I absolutely enjoy this program! The sad part is, I have to endure the most obnoxious ads from the Discovery channel for their terrible 'reality based shows'. We all know that these shows are so far from reality it's ridiculous. I've been a fan of 'How The Universe Works' for a long time and always look forward to seeing them. It just takes a lot for me to be subjected to all the other terrible programming on the Science Channel.
It's entertaining but also becomes annoying when you want to watch something that's real. This video is real but also some facts are based on theory. You have to take what you get & separate the facts from fiction or "educated" guess.
I hate that there is so much reliance on these scripted shows rather than the original content.I am a big fan of "How the Universe Works". So when they run mutiple episodes like this, I ❤ it!
I agree that this video is very interesting and on point for what we know about the universe. Where we accurately use true science and not science fiction in programming is where things should stay. Bigfoot and alien contacts and other programs like that should not be supported.
How awful to be subjected to the intrusive ads which tend to spoil this beautiful program. I watch this and others like it without interruption on You Tube. I hook my laptop to my 65" screen (VGA to HDMI) in the living room, and voila! Fabulous, colorful programming without ads.
If there happens to be intelligent life such as ours out there somewhere, they're going to be just nearly impossible to find as we are. Do you have any idea how infinitesimally small earth is in the universe? Yes, it would be possible for some intelligence to follow our radio waves, assuming they are close enough to have received them yet.
Yes , so where are we looking for a planet like ours ? And how to get there ? Rather look in our region ? Until the light speed issue is solved , how far can we go ?
Maybe our species is spread all throughout the universe from some major event, in such case we would all potentially be evolving on the same timeline. I'd say if this were the scenario, perhaps we may even find ourselves out there In the next few centuries . If not, remnants of our attempted communications may be discovered many thousands of years later on the other side of this big ol bubble.
What make you think we’re so intelligent? Expecting other living beings to pick up our radio waves is like expecting a deaf person to hear us talk? Maybe we or looking and or expecting incorrectly. We’re still in the level 1 caveman infancy stage of civilization. We’re still on rocket boosters.
Folks, I love all things outer-space and I’d be as excited as anyone if we discovered life, intelligent or otherwise, on other planetary bodies either in or outside our solar system, or they discovered us - but let’s face it: As much as it saddens me to say so, the chances are better than fair that the human race will go down to its extinction having never detected life anywhere but here. I would dearly love to be wrong, but I have a feeling I’m not.
We can use our own Galaxy as something to compare other Galaxies. There must be a way to create an atmosphere artificially. Unfortunately it would probably take millennium to create something even close to a safe & more importantly stable conditions. Finding a planet with our gravitational pull is a needle in a haystack with another haystack, for now. Even if we did find one it would be extremely too far to reach. All this sucks
I always find it strange that you practically never hear of nuclear propulsion when documentaries discuss potential interstellar travel methods... project Orion already demonstrated the feasibility of this type of propulsion system, and it could get us to alpha Centauri in just 100 years using currently existing technology. No need for someday maybe propulsion systems.
The blame for the failure of the Orion project can be laid mainly on the Outer Space Treaty of 1967. Hot wars change borders and cultures. Cold wars change ways of thinking.
I wonder if there are planets out there with a huge gravity, but the size of a grain of sand. Could a black hole just be a grain of sand that weighs a lot? If there was a grain of sand that had a lot of gravity, could we capture it and harness it for energy?
Yes and Yes. Much closer to Yes than No. You're looking for a Kugelblitz Black Hole. BHs can be microscopic. They just have to be ultra-dense. If we surrounded a big ball of iron with big nuclear bombs and lit them all off at the same time, it should compress the ball into a BH. And, yes, we could produce an enormous amount of energy by tossing stuff into the accretion disk around the BH. Would also be a great way to get rid of radioactive waste and stuff. One problem is that it would be so small it would be almost impossible to get anything into.
I love the idea after reading the Reading K Stanley Robinsons trilogy on terraforming it. but it's also a giant potential gardening project..and how therapeutic is gardening..I think a lot of us would deeply connect to the idea of making Mars a garden world.
The music shouldn't become so loud it drowns out the commentary. These videos are so well done, that effect was really surprising. It happens in the segment a little after about 1:57.
I'm always thinking: why this all exists? We might never know how universe was created or if there are other universes. But why there even is a universe with laws? It's probably my human brain that needs a reason and explanation but it's really amazing to just think about it. Thanks for an interesting video.
One of my favorite ideas is either the completely unprovable multiverse theory, that there are infinite iterations of the universe each slightly different and likely most of the time there is not life as the ‘rules’ or makeup of the universe don’t support it. But just like life on earth, after an unknown number of random iterations, one had the qualities that could support a small chance of life, and then one or more spaces in the universe (I hope more than one) had the right things happen for life to form, etc. It’s just as unprovable as any other idea of why we exist, I just like the through line with what has happened to form life on the Earth.
@Reacher Jack: When we are very young one of our first words is WHY ? Why can't I have that. Why do I have to share ? Why can't I do what Mommy and Daddy do ? Why is the sky blue ? After that last question we strive to understand. Curiosity is curiously human nature.
Until we can get full coverage and unbridled enthusiasm world wide on space travel, we won’t even get out of our own Milky Way for thousands of years- first we need to learn how to travel back and forth to our moon…..practice practice makes perfect ❤
Our understanding of what intelligent life is, is rather limited by our egos. We highly underestimate the intelligence of the creatures around us on earth today!!!
Life as we know it is unique to this planet, we are a part of this planet!!! Our 5 senses gives us awareness in this world, going outside this world would be like a fish out of water! The stars could be a form of life
I'm not that smart, but I always question one thing, why do they always say water is life. Or any lifeform needs water. Why can't there be any life forms that don't need water? After all, we are talking about extraterrestrial life. right?! There may be entirely other stuff we never ever could imagine instead of looking for water.
I believe that the reason for this way of thinking is twofold. First is the overwhelming abundance of water in the universe of which the liquid form is an ideal solvent to support chemical processes. The second point is that carbon is the most versatile element to support biological processes and it interacts very well with water. This is not to say that other elements would not support the rise of life but rather that carbon and water would be more likely to produce life due to their versatility in acting with hydrogen and other very abundant elements found in nature
I just watched how the universe Works season 11 episode two, which suggested much of mars’s water likely didn’t boil away, but went into minerals in rocks. Why the contradictions? this episode states that without earths atmosphere most of the water, would boil off into vapour?
That is because when Mars had water few billion years ago and when that was the case, Mars did have an Atmosphere and that Atmosphere didn't just go away all at once it probably took 100 millions of years for it all to go away and gave the water time to get into the ground and rocks.
The more we learn , the less we know . is there a cosmic map with an arrow pointing to Earth ? Yes , somewhere in the Milky way , one of billions of places . Just where are they ? Where are we looking and why ? Going back in time to the start ? Will look nothing like it is today :-) Really busy back there :-) We are on the edge of a spiral cluster , why are we not looking at things out our way ?
We vastly overestimated the possibility of life out there in the Universe because of the specific conditions on Earth that brought life into existence are so very rare because it requires an impact early on that melts the interior of the early Earth and creates this marvelous magnetic field that protects life from cosmic rays. Because of all the specific conditions required to have life it becomes obvious that life out there is as rare as is the Earth itself.
Jupiter has a magnetic field, none of the earth characteristics are unique. The counter argument is that there is an unbelievable number of planets out there, so they are likely exist, by probabilities alone.
Spoken like someone who has a LOOSE grasp of the processes that spawned our planet. How do you over estimate when you have only sampled .01% of the universe, if that much.
All planets have a molten interior upon formation because they form by accretion. Which is just material slamming into each other. It generates heat. They cool at different rates depending on size.
I hope other countries not only the USA, start going beyond orbit and the moon that will boost our eagerness to explore again There is too little incentive for space exploration. The first country that lands on Mars will be the next super power of science. Humans at this point are like dirty water drying out and dying cause we don't move forward because we are waiting on the rainy day (money).
When oxygen gets ionized (O2-) by the sun's plasma it can become water molecules because the sun's plasma contains free floating protons. Plants produce oxygen.
Is a star manufacturer of planets if so what is the cycle period and production! Super strange ! I am happy I got a chance to live on earth! Thank you!
For all those that ask "Why haven't we been back to the Moon" The bigger question is why did we go to the Moon in the first place ? It wasn't because we could, it was because we had to. We were in a pissing contest with the Soviet Union and once we won the charm was over. Human nature is not driven by by scientific discovery and exploration. But it is driven by who can "win". It is amazing the United States Moon program even lasted until Apollo 17. We had already won so why keep going ? The program was extremely expensive and nothing was new and exciting anymore. NASA didn't fail us, we failed NASA.
Everybody's always so hype about meeting alien life, but never worry on what if meeting alien life leads to enslavement or worse, human extinction. Hate being a kj, but playing with fire isn't always fun
It behoves me that people living in a magnetic field stronger than 0.5 gauss would have the unwanted luxury of migraines and systemic problems of untold varieties.
Why should we worry about finding other worlds to live even if we did find one that was compatible we would screw it up anyway like we've done this one
I was all for going to Mars until the terraforming part where we pump out toxic gas and release all the planet's frozen water. Did they forget that Mars has no core to keep the water rooted down to the planet? It would all evaporate into space over time and Mars would eventually be left direr than it had been before humans had arrived! All this sounds horrible! Not to mention how we have no idea if Mars has life can't detect yet. Maybe microbial life under the plant's surface or even something else, who knows?. At any rate, we would be destroying any life or possible evidence of life by contaminating the planet.
57:38 Isn't pollution so much more breathtaking in space? It's really too bad that it's just as stupid of an idea there as it is here. (even more so, because after we're done destroying this planet we won't even be able to leave so we can destroy another one)
I am about the same age as Dr Zubrin, except I got my PhD in cognitive psychology. Back in the 70's when the Apollo program got cancelled, most of us still thought we'd get back to the moon and mars soon. There was an optimism that is dead today. Then Nixon gave China "most favored nation trade status" and dropped all tariffs so corporations could use cheap labor, sending all high paying non-college jobs overseas. Wages stagnated, nobody earns as much as their parents did in terms of buying power, homeless are everywhere and people no longer have that optimism about the future. Americans expect a future with less freedom, more crime, more poverty, crumbling infrastructure and the money to fix it given to the military instead. We let corrupt politicians funnel all our wealth into weapons in exchange for kickbacks from weapons makers, so we are now too broke to accomplish anything other than fighting wars over diminishing resources. Our only hope is that China will colonise space while we watch them on TV, possibly from inside a tent on the sidewalk of a decaying city.
Why does life necessarily need oxygen? Carl Sagan proposed the possibility of alien life based on hydrogen. Why not methane or some other natural element?
There's plenty of life on earth that doesn't need oxygen. And hydrogen and silicon and other types of life are possible, but it's much less likely to happen than carbon based life.
Obviously other beings are way older than us, maybe by millions of years, which makes sense, life wouldn't have sprung up at the same time, there's beings that travel unimaginable distances, but they don't travel at the speed of light in a linear way we think, they bend or fold space/time to blink in and out of different places, different dimensions, we're likely the youngest, most primitive intelligent beings in the universe.
You assume that life evolves at the same pace everywhere, but there is as likely that live evolves as it doesn’t. Even is there where other systems with all the same conditions as Earth does not mean that life would evolve since it took an almost infinite series of events at the right time for live to have a chance to evolve and an other whole series for life to evolve intelligence so in places it might take 5 billion years and in another 20 billion. When it comes to the matter of folding space, this idea comes from movies like Dune
We are less than 100 years old in actual technology. And, only since last 50 years the our technology improved to a better level. So, only based on 50 years knowledge we are talking about we being the only intelligent species. Like a kid, who immediately gets satisfied for his little achievements thinking he is only smart kid😃. I think as the technology will evolve further, many aspects of science will get unfolded. Who knows aliens maybe on planet already..
I applaud Dr Zubrin for his attitude and persistence but I am very disappointed with what NASA has become. They evolved from a goal oriented can do organization into a politically motivated self sustaining bureaucracy more oriented towards their own survival rather than achieving any specific goals and like any other bureaucratic entity the main focus seems to be spending as much money as possible
I’m no expert but I’ve said time and again on many a’ thread .. We need to be looking at G mid sequence stars with similar mass, brightness and metallicity to our sun .. Exclusively seek out solar analogs to study …. Get on with it !
Not just the Amazon. Borneo has a issue either deforestation due to palm oil cultivation. A lot of animals are on the endangered species list and some has gone completely extinct. It sad that people don't understand is the rain forest go, we are all dead.
This idea has to stop immediately, the next mission must be the moon. there are minerals that will be needed too make this dream a reality. A base on the moon with a total plan as per logistics and the need for an area of low gravity makes that the next plan of action. Oh and the idea that there are no pathogens on that planet all you must do is look at Africa for all the exotic new diseases that came out of the ground from war and mining. Mars just cannot be the next course of action, please people....
Yeah but we need dreamers. Without the dreamers we don't get the full send explorers that Advance our Horizons. Triggered by inspiration to do the extraordinary. On the other hand speculation and Theory taken as fact can be harmful and for sure highly annoying
This guy lost me when he said "we'd be extending life for smokers" by sending them without tobacco. An answer for everything.. come on! I would prefer he said " yeah.. there's gonna be risks.' I have a feeling he wants his name associated with Mars and that shouldn't be your driving factor. There are people lives involved and that should be your first, second and third priority, period! The talk of going and staying on Mars for extended periods of time are kind of crazy.. people have a hard enough time living on Antarctica and there's all the basic comforts of home.. strip away the oxygen.. the warmth (yeah compared to Mars Antarctica is wildly warmer) take away that a 7/11 is only a cpl thousand miles away and plenty of other things and you have Mars. Sure, we will get there 1 day but I don't see it in a few more life times.. sorry guy.
Why are we stuck on life requirements of water?? I think we need to think out the box. We can’t breathe water like fish do. What if there’s life beings that don’t have to breathe water nor oxygen?
God created water for life on Earth and for our human existence. From it's macro properties to it's chemical properties to it's quantum properties water was created so life on Earth could flourish - including we, humans.
Only the earth has elements that support life. Life so complex it couldn't form by natural selection for a billion years. Water is so necessary, that atheists insist water must exist on other planets, especially Mars, where it is so cold CO2 becomes liquid, and dry ice on the polar regions.
Robert Zubrin's constant whiney preachey I have a PhD therefore superior is very off putting. His I'm cross attitude was even criticised by that government review panel. He alone caused me to stop watching this. The British narrator was, as always, very endearing.
what happens if when you warm up mars, it then cools the earth. Why do humans think they can change things like this. not saying this is what would happen, but we don’t know that.
Why wouldnt you only send 6months worth of supplies at a time. Once on mars send a ship of supplies only therefore, 6 months later our astronauts receive a resupply vehicle bringing anything needed to help survive a 1yr stay on mars.
You talking about too much danger out there you go to the beach Danger War is dangerous So do we just give up Get butts to the mars Build a base Can we go on Other planets Get to the moon wasting an easy We did it Let's go on😊
I will answer the question without watching the video. We will discover alien life on exoplanets when we start exploring space. Many decades if not centuries away.
Some prisoners in America have spent longer than that in Isolation....why not ask them if they would like to take the ride....? they are mostly physically fit...and already withstood the isolation test.
The answer my friend is 42, courtesy of the Hitchhiker's Guide too the Universe. Seriously though this question led me down a rabbit hole way to early in the morning. My best guess is the History Channel under the title you seek. Best wishes and happy hunting. P.S. If you find it let me know, please and thank you
@DeereJohn haha thank you so much for the effort 😃. So a little history behind my question, this is my favorite show going on about 10 years now. I got interested in space and science about that long ago (can’t believe it took until my 40’s to catch the bug lol) and of all the documentaries I’ve collected over the years How The Universe Works is my favorite. I like both of the narrator’s and the visual has always been spectacular. Anyway I work in the middle of nowhere on a rotating schedule of days and nights, and when on nights I use shows like this to fall asleep and when I watched this one last week I didn’t recognize it so that’s why I asked. As soon as I got home for my days off I searched and discovered they have started season 11 so I bought the season pass. I’m about to start watching it now so I’ll let you know if I see this episode in it. Thanks again for the reply.
i drilled wells all over the country and beyond close to 5 plus miles down, at every depth from 0' to 30,000' the there is water and it is a nuisance in production, it could go much much deeper then we will ever reach and even imagine possible, this could be where life on mars and venus could be and we will never know it...
Yes we need water to live but if we were a water world there would be no steel , no fire , no glass no electricity , no smelting , no technology. A fish no matter how smart can't make a telescope or assemble a spaceship ever .
Wow. I haven't heard Mike Rowe narrate in quite awhile. I love these space videos. It's fascinating.
I absolutely enjoy this program! The sad part is, I have to endure the most obnoxious ads from the Discovery channel for their terrible 'reality based shows'. We all know that these shows are so far from reality it's ridiculous. I've been a fan of 'How The Universe Works' for a long time and always look forward to seeing them.

Do you have any idea how infinitesimally small earth is in the universe? Yes, it would be possible for some intelligence to follow our radio waves, assuming they are close enough to have received them yet.
I think you should tell cosmologists how large the galaxy is and how small planets are. They probably didn't think of that.
Yes , so where are we looking for a planet like ours ? And how to get there ? Rather look in our region ?

It is truly amazing to me how high and complex the human brain can be, and at the same time, how low and ignorant our species can be at the same time.

Hot wars change borders and cultures. Cold wars change ways of thinking.
It would be more like 30,000 years. Or more realistically 65,000 years.
You watch too much TV
Come over to SFIA. Issac Arthur is all over that stuff. Orion Drives, and Shakadov Trursters are small potatoes on SFIA.
I wonder if there are planets out there with a huge gravity, but the size of a grain of sand. Could a black hole just be a grain of sand that weighs a lot? If there was a grain of sand that had a lot of gravity, could we capture it and harness it for energy?
No no and no.
Gravity is dependent on mass.
Yes and Yes. Much closer to Yes than No.

@Everett Cox: Yes, yes and yes. Ever heard of a Neutron star ?
@DeereJohn k
Imagine what the first telescope views from the surface of Mars will look like. 🌏
With a stronger magnetosphere, less radiation can pass to the planet, which I would argue could impact the evolution of life.
I love the idea after reading the Reading K Stanley Robinsons trilogy on terraforming it. but it's also a giant potential gardening project..and how therapeutic is gardening..I think a lot of us would deeply connect to the idea of making Mars a garden world.

Maybe "why" isn't the right question? maybe we should be asking "how" instead? but ya, I'm right with ya.

It’s just as unprovable as any other idea of why we exist, I just like the through line with what has happened to form life on the Earth.
I think this exact thing on a daily basis. It's so mind blowing how we exist and how everything works.
@Reacher Jack: When we are very young one of our first words is WHY ?
Why can't I have that. Why do I have to share ? Why can't I do what Mommy and Daddy do ?
Why is the sky blue ? After that last question we strive to understand.
Curiosity is curiously human nature.
The universe is so amazing that it created us to understand itself
This is great stuff for all the family to view. KZclip please show more of this kind intelligent programs.
Life is so abundant in this universe that we wouldn't know it if we did see it
Awesome video ! I like it so much . Thank you for sharing . I hope that you will find Aliens staying in our galaxy one time . Happy week to you !
Music is too Loud!!!!🙄

Do you mind if I emailed your comment to an astronomer friend? I want to read what he says about it.

All planets have a molten interior upon formation because they form by accretion. Which is just material slamming into each other. It generates heat. They cool at different rates depending on size.
I agree with the beginning of your statement
there's no mistaking Mike Rowes baritone voice. I find it soothing and puts me to sleep lol
I hope other countries not only the USA, start going beyond orbit and the moon that will boost our eagerness to explore again There is too little incentive for space exploration. The first country that lands on Mars will be the next super power of science. Humans at this point are like dirty water drying out and dying cause we don't move forward because we are waiting on the rainy day (money).
I would guess the biggest problem with other countries getting involved is financing. It's hard to do space travel on the cheap.
I like that Dr.Robert Zubrin talk about his plans to Mars mission, and others talk about many other things.
I believe in my heart there is life out there all these plants out some thing is out there
When oxygen gets ionized (O2-) by the sun's plasma it can become water molecules because the sun's plasma contains free floating protons. Plants produce oxygen.
Is a star manufacturer of planets if so what is the cycle period and production! Super strange ! I am happy I got a chance to live on earth! Thank you!
For all those that ask "Why haven't we been back to the Moon"
The bigger question is why did we go to the Moon in the first place ?
It wasn't because we could, it was because we had to.
We were in a pissing contest with the Soviet Union and once we won the charm was over.
Human nature is not driven by by scientific discovery and exploration.
But it is driven by who can "win".
It is amazing the United States Moon program even lasted until Apollo 17. We had already won so why keep going ?
The program was extremely expensive and nothing was new and exciting anymore.
NASA didn't fail us, we failed NASA.
I don't know why people think you'll see any of the time playlist I see you're back let School
Not being an exomoon, Earth is in fact at a disadvantage. or at least not having a large planet to moon around on leaves earth at a disadvantage.
Life as we know it needs water and oxygen to survive. Who knows what aliens need?
Explaining the universe and all its unbelievable complexities is a dirty job indeed
ALIEN LIFE MUST EXIST IF ITS TRUE OR WE ARE ALONE BOTH TERRIFYING
Everybody's always so hype about meeting alien life, but never worry on what if meeting alien life leads to enslavement or worse, human extinction. Hate being a kj, but playing with fire isn't always fun
It behoves me that people living in a magnetic field stronger than 0.5 gauss would have the unwanted luxury of migraines and systemic problems of untold varieties.
Why should we worry about finding other worlds to live even if we did find one that was compatible we would screw it up anyway like we've done this one
I feel asleep and woke up to this guy talking about cosmic phenomena and the infinite, ever expanding universe.
"Will we live on more than one planet?" why if we already do?
I was all for going to Mars until the terraforming part where we pump out toxic gas and release all the planet's frozen water. Did they forget that Mars has no core to keep the water rooted down to the planet? It would all evaporate into space over time and Mars would eventually be left direr than it had been before humans had arrived! All this sounds horrible! Not to mention how we have no idea if Mars has life can't detect yet. Maybe microbial life under the plant's surface or even something else, who knows?. At any rate, we would be destroying any life or possible evidence of life by contaminating the planet.
57:38 Isn't pollution so much more breathtaking in space? It's really too bad that it's just as stupid of an idea there as it is here. (even more so, because after we're done destroying this planet we won't even be able to leave so we can destroy another one)
I am about the same age as Dr Zubrin, except I got my PhD in cognitive psychology. Back in the 70's when the Apollo program got cancelled, most of us still thought we'd get back to the moon and mars soon. There was an optimism that is dead today. Then Nixon gave China "most favored nation trade status" and dropped all tariffs so corporations could use cheap labor, sending all high paying non-college jobs overseas. Wages stagnated, nobody earns as much as their parents did in terms of buying power, homeless are everywhere and people no longer have that optimism about the future. Americans expect a future with less freedom, more crime, more poverty, crumbling infrastructure and the money to fix it given to the military instead. We let corrupt politicians funnel all our wealth into weapons in exchange for kickbacks from weapons makers, so we are now too broke to accomplish anything other than fighting wars over diminishing resources. Our only hope is that China will colonise space while we watch them on TV, possibly from inside a tent on the sidewalk of a decaying city.
Why does life necessarily need oxygen? Carl Sagan proposed the possibility of alien life based on hydrogen. Why not methane or some other natural element?
There's plenty of life on earth that doesn't need oxygen. And hydrogen and silicon and other types of life are possible, but it's much less likely to happen than carbon based life.
Maybe life is the universe as it exist
Obviously other beings are way older than us, maybe by millions of years, which makes sense, life wouldn't have sprung up at the same time, there's beings that travel unimaginable distances, but they don't travel at the speed of light in a linear way we think, they bend or fold space/time to blink in and out of different places, different dimensions, we're likely the youngest, most primitive intelligent beings in the universe.
Yep. If there were already dudes that could fold spacetime, theyd have already left a mark everywhere that we could have seen in the 1950s
You assume that life evolves at the same pace everywhere, but there is as likely that live evolves as it doesn’t. Even is there where other systems with all the same conditions as Earth does not mean that life would evolve since it took an almost infinite series of events at the right time for live to have a chance to evolve and an other whole series for life to evolve intelligence so in places it might take 5 billion years and in another 20 billion.
When it comes to the matter of folding space, this idea comes from movies like Dune
It takes a God to make a planet composed of 2/3 water. It isn't that easy to do.
Going to mars will be to scary when I was young I watched a movie called space idiocy 2001 still makes my hairs on my neck stand up
Excellent stuff😮 Nicholas Moore British.
We are less than 100 years old in actual technology. And, only since last 50 years the our technology improved to a better level.
So, only based on 50 years knowledge we are talking about we being the only intelligent species. Like a kid, who immediately gets satisfied for his little achievements thinking he is only smart kid😃.
I think as the technology will evolve further, many aspects of science will get unfolded. Who knows aliens maybe on planet already..
I hope Dr. Zubrin did not lose his sanity wasting his life with NASA in charge of a Mars program that never crossed the street.
I applaud Dr Zubrin for his attitude and persistence but I am very disappointed with what NASA has become. They evolved from a goal oriented can do organization into a politically motivated self sustaining bureaucracy more oriented towards their own survival rather than achieving any specific goals and like any other bureaucratic entity the main focus seems to be spending as much money as possible
I’m no expert but I’ve said time and again on many a’ thread .. We need to be looking at G mid sequence stars with similar mass, brightness and metallicity to our sun .. Exclusively seek out solar analogs to study …. Get on with it !
hey , thanks , but why not HD quality !
Not just the Amazon. Borneo has a issue either deforestation due to palm oil cultivation. A lot of animals are on the endangered species list and some has gone completely extinct. It sad that people don't understand is the rain forest go, we are all dead.
The universe is ALL THAT IS. So there is nothing outside of it!!!!
This idea has to stop immediately, the next mission must be the moon. there are minerals that will be needed too make this dream a reality. A base on the moon with a total plan as per logistics and the need for an area of low gravity makes that the next plan of action.
Oh and the idea that there are no pathogens on that planet all you must do is look at Africa for all the exotic new diseases that came out of the ground from war and mining. Mars just cannot be the next course of action, please people....
Yeah but we need dreamers. Without the dreamers we don't get the full send explorers that Advance our Horizons. Triggered by inspiration to do the extraordinary. On the other hand speculation and Theory taken as fact can be harmful and for sure highly annoying
i wish new videos would be put out. This video is just clips from other videos that are over 10 years old. Ive seen them all many times over the years
This guy lost me when he said "we'd be extending life for smokers" by sending them without tobacco. An answer for everything.. come on! I would prefer he said " yeah.. there's gonna be risks.' I have a feeling he wants his name associated with Mars and that shouldn't be your driving factor. There are people lives involved and that should be your first, second and third priority, period! The talk of going and staying on Mars for extended periods of time are kind of crazy.. people have a hard enough time living on Antarctica and there's all the basic comforts of home.. strip away the oxygen.. the warmth (yeah compared to Mars Antarctica is wildly warmer) take away that a 7/11 is only a cpl thousand miles away and plenty of other things and you have Mars. Sure, we will get there 1 day but I don't see it in a few more life times.. sorry guy.
Why are we stuck on life requirements of water?? I think we need to think out the box. We can’t breathe water like fish do. What if there’s life beings that don’t have to breathe water nor oxygen?
God created water for life on Earth and for our human existence. From it's macro properties to it's chemical properties to it's quantum properties water was created so life on Earth could flourish - including we, humans.
Only the earth has elements that support life. Life so complex it couldn't form by natural selection for a billion years. Water is so necessary, that atheists insist water must exist on other planets, especially Mars, where it is so cold CO2 becomes liquid, and dry ice on the polar regions.
Why are we causing mass extinction here at home? It is the most urgent scientific and existential question today.
Robert Zubrin's constant whiney preachey I have a PhD therefore superior is very off putting. His I'm cross attitude was even criticised by that government review panel. He alone caused me to stop watching this. The British narrator was, as always, very endearing.
He's incredibly rude and an egomaniac. I'm surprised he got any followup meetings at all...
And trees for oxygen 😮
what happens if when you warm up mars, it then cools the earth. Why do humans think they can change things like this. not saying this is what would happen, but we don’t know that.
Why wouldnt you only send 6months worth of supplies at a time. Once on mars send a ship of supplies only therefore, 6 months later our astronauts receive a resupply vehicle bringing anything needed to help survive a 1yr stay on mars.
You all can't face the fact that we are the last living planet 🌏 this is it folks lol ❤😂🎉
Why look for trouble? Can the earth defend itself from hostile aliens? Just prepare for the inevitable.
You talking about too much danger out there you go to the beach Danger War is dangerous So do we just give up Get butts to the mars Build a base Can we go on Other planets Get to the moon wasting an easy We did it Let's go on😊
I feel sorry for the first people who attempt to go.... as you will quickly find out, this is a death wish with no return ticket.
I will answer the question without watching the video. We will discover alien life on exoplanets when we start exploring space. Many decades if not centuries away.
It's mag-KNEE-toes-fear, not magnet-Oh-sphere. Sheesh!😄
200 golden earths and 500 platinum earths? The universe has one valuable PS5...
Any science programme with Michelle Thaller in, is OK by me.
Some prisoners in America have spent longer than that in Isolation....why not ask them if they would like to take the ride....? they are mostly physically fit...and already withstood the isolation test.
😮😊😊😊❤
This video is all over the map subject wise. Good snooze material though.
Lol yeah, exactly what I used it for.
BUT!!! We have an atmosphere that burns any germs 🦠 that come from meteor when they enter the planet.
If u go to another country u become an alien 😂
I didn't know Dave Mustane was a scientist
What season of how the universe works is this please?
The answer my friend is 42, courtesy of the Hitchhiker's Guide too the Universe.
Seriously though this question led me down a rabbit hole way to early in the morning.
My best guess is the History Channel under the title you seek.
Best wishes and happy hunting.
P.S. If you find it let me know, please and thank you
@DeereJohn haha thank you so much for the effort 😃. So a little history behind my question, this is my favorite show going on about 10 years now. I got interested in space and science about that long ago (can’t believe it took until my 40’s to catch the bug lol) and of all the documentaries I’ve collected over the years How The Universe Works is my favorite. I like both of the narrator’s and the visual has always been spectacular. Anyway I work in the middle of nowhere on a rotating schedule of days and nights, and when on nights I use shows like this to fall asleep and when I watched this one last week I didn’t recognize it so that’s why I asked. As soon as I got home for my days off I searched and discovered they have started season 11 so I bought the season pass. I’m about to start watching it now so I’ll let you know if I see this episode in it. Thanks again for the reply.
If you haven't found it, this might be season 7 episode 9
@Brian Ziemba thank you if you collect these season 11 is out😃
its called star DNA what do we look like ?
What was that at the back of the head?? Looked like a kickstand...
i drilled wells all over the country and beyond close to 5 plus miles down, at every depth from 0' to 30,000' the there is water and it is a nuisance in production, it could go much much deeper then we will ever reach and even imagine possible, this could be where life on mars and venus could be and we will never know it...
we need to seed mars first start with algee then other plants that convert the air first
Lol.
You can't give Mars a magnetic field. Ever.
You dont know that. We may figure out a way to reactivate a molten core.
@Gym Hayes 0
Why not?
Mars is too small...
WTF is up with the sound at 1:57:00 ?
It gets LOUD as F^&% for some reason.
Why does this happen so often in these videos?
If I hear the ‘Goldie lock zone’ explained one more time….I may just focus on earth 😭😭 every video saying same things
Launch some volatile stuff on rockets now to try and terraform mars.
Why not just enjoy our own planet instead of looking for life elsewhere?
I am pretty sure they are already trying to engineer mars. They just aren’t telling us.
Precious❤
Mars is miserable. Planet-wide dust storms, cold, no water, (no magnetosphere? What about solar radiation storms?)
VĪRIETIS TEICA, VĪRIETIS IZDARĪJA!
Yes we need water to live but if we were a water world there would be no steel , no fire , no glass no electricity , no smelting , no technology.
A fish no matter how smart can't make a telescope or assemble a spaceship ever .
Ah, no fucking shit? Geez, you're a fucking genius, dude.
Goodnight, legends.
Maybe one day. 2029 maybe….
1:24:30 I would quit smoking too go to Mars
How old is this? It ain't new, that's for sure.
