10 Best Places in the Universe if you’re a Human (collab with Paul Sutter)


this is another collaboration with
astrophysicist Paul M Sutter of Ohio State University this time we’re looking
at the 10 best and 10 worse places to be in the universe if you’re a human for
part to check out Paul’s channel link in the end screen and in the description
below now without further ado here are the 10 best places in the universe if
you’re a human number 10 the upper atmosphere Venus Venus is a very strange
planet on its face it looks like the absolutely most awful place you could
possibly find in a solar system it’s a hellish environment of sulfuric
acid crushing pressure and extreme heat from a runaway greenhouse effect but at
the same time it boasts a layer in its upper atmosphere that is one of the most
Clement and earth-like environments in the solar system so much so that if you
lived in a balloon colony suspended in the atmosphere at this level you could
accidentally tear your spacesuit and not die and in fact take your time getting
back to your colony this is because within this zone the atmospheric
pressure is the same as Earth meaning you don’t get gases leaking in or out as
badly from the tear as you would say on Mars where the low atmospheric pressure
would suck the air out of your suit very rapidly this is one of the few places in
the solar system other than earth where this can happen as a result Venus is an
interesting planet to humans though currently often overlooked it has enough
resources to be terraformable over a long period of time and it has that
Clement area where humans can hypothetically live while the
terraforming occurs though that colony would likely be highly dependent on
earth for centuries and there is a potential astrobiological techno
signature in this one as we gain the ability to study exoplanet atmospheres
and say we see what should be a Venus like world given its placement and its
system close in to its star but instead appears atmospherically to be an
unlikely analog of earth as far as oxygen levels and chemical composition
goes it would need to be considered that someone may have made it that way number
nine Trappist 1d the search for and the discovery of exoplanets has absolutely
exploded in recent years we know of hundreds upon hundreds already and we
suspect there men more as a result of this we can now say
with confidence that planets aren’t rare in the Milky Way but what of planets
like Earth we simply don’t have a good understanding of how common our planet
is it could be an exceedingly rare type subject to a very specific circumstance
which increasingly seems to be the case but there could be others in the galaxy
but so far we have not seen a twin of this world but we do have one that may
come close at least we think it is right now it’s a planet in orbit around the
red dwarf Trappist one and it currently holds the highest score on the earth
similarity index out of any other exoplanet 0.91 out of one study of this
planet is ongoing and it could well go down but as it stands new data shows
that as much as 5% of the makeup of this planet seems to be water very possibly
in liquid form in other words it may have oceans also studies with Hubble
showed that the planet lacks a thick hydrogen atmosphere opening up the
possibility of a more earth-like atmosphere but we know little else it
could be a greenhouse effect atmosphere like Venus or a carbon dioxide one like
Mars but if it turns out similar to earth and we start seeing odd oxygen and
methane levels as ongoing study continues then life would be on the
table as the origin for that number 8 colonized ice shell moons when we think
of colonizing a planet we tend to think in terms of habitats domes and eventual
terraforming in other words recreate on another world the conditions of Earth
where we evolved key to this is the one thing that we’re going to need lots of
anywhere we choose to colonize an ample supply of liquid water but we are land
creatures fundamentally yet we venture into the oceans with submarines and
ships it also pays to remember that Earth also has water environments that
teem with life that hypothetically could also be colonized realistically
underwater colonies in Earth’s oceans would be limited to shallow waters to
avoid having to deal with the extreme pressures of the deep but they are in
principle possible with the right technology trouble is
there’s no reason to do this on earth but in thinking about colonizing a body
that doesn’t have a land environment quite like Earth rather a nice shell but
does have liquid water oceans beneath it might be viable to locate such a colony
in that ocean rather than at the surface the obvious candidates for this are the
ice shell moons like Europa or Enceladus while surface colonies likely would end
up being more practical on these moons should we ever choose to do it
underwater components could also be useful especially in regards to
harnessing any geothermal energy present at these places the high pressure in
these oceans opens up questions here but ultimately an ocean environment is at
least more familiar to humans than the surface of a frozen Jovian moon number
seven ignorance is bliss we live in a time where it is at least possible to
largely understand the universe though we are still very much within the
learning curve but there is a part of our universe so distant that light does
not travel fast enough to overcome the rate of expansion of the universe in
between barring faster than light travel we will
never see this part of the universe and we don’t know how large it is and it
gets worse as the universe expands eventually everything becomes so distant
from everything else that eventually isolation becomes the rule as a result
future civilizations may have no way of ever knowing the Big Bang ever occurred
or that there’s an entire universe out there as such why pay attention to the
blackness of space outside of your own galaxy future scientists may say that
nothing could come of it and they may well conclude that their galaxy is all
that there is and it might as well be what exists outside of what you can know
or what affects you is meaningless just as it’s meaningless to ask what happened
before the Big Bang and the onset of time if that concept even makes sense
this limited scientific toolkit could leave a human-like future civilization
in a kind of blissful ignorance never able to know that your universe could
someday come to an end number six calm super-earths earth is an
amazing world but it’s by no means perfect at times in its history it’s
nearly frozen over has caused mass extinctions from periods of widespread
volcanic activity frequently features extreme weather and all manner of other
natural disasters earth can be a harsh planet but what if planets that might be
a bit calmer it’s possible to envision a world perhaps a bit larger than Earth in
circumstances that may make it possible for it to experience less extreme
weather or a lack of ice ages and perhaps placement in a star system that
sees less asteroid impacts and so on as such it may be possible that there are
worlds out there that are better for humans than earth is oddly though this
may only be true for us humans any species native to such a world faces a
possible challenge it may never evolve intelligence with better more Clement
conditions comes a less of a need for intelligence it has been suggested that
the general lack of true intelligence and sea life on earth most intelligence
in the ocean is limited to animals that evolved to go back into the ocean after
a period on land might indicate that oceanic life has it too easy this may be
true for land life on a Clement super earth and worse water itself can become
an enemy on full-on water worlds where no land exists but very deep oceans do
the conditions of earth-like life may never arise volcanism may never occur on
these worlds for example and certain gases needed for heating might not get
released into the atmosphere perhaps creating ice shell conditions where the
liquid water is locked up under the ice life might exist but it might also not
be able to progress past a certain point number 5 Goldilocks zones as the earth
illustrates where you are located in relation to your star is crucial to the
evolution and existence of life as we know it known as zones of habitability
or the Goldilocks zone for being just right they provide a basic framework for
what planets earth like life and humans can comfortably live on the first of
these zones are the circumstellar habitable zones this essentially is
where Earth lives in our solar system just the right distance from the
for liquid water this zone depends on what type of star our planet orbits in
this zone can be closed into the star if it’s cool or far from the star if it’s
hot but there is also a Galactic habitable zone
this one is more forgiving and that a large part of the stars in our galaxy is
within it but certain areas such as the center of the galaxy or inside a dense
star cluster probably would not host planets where humans could easily live
if at all the reason for this is that you’re simply too close to other stars
and subject to their radiation and nearby supernovas at the furthest
reaches of the galaxy you don’t have that problem but that far out presents
other issues that may make it uncomfortable for humans such as a
scarcity of raw materials of course habitable zones are subject to
exceptions such as the ice shell moons like Europa and with technology humans
could live far outside these zones but as a matter of the best places in the
universe for humans the habitable zones provide the best starting conditions
number four virtual realities well it could be said that some basic Clement
environment is needed for human life that equation may change in the future
when humans are able to alter our own biology or abandon it entirely there the
rules change for Machine life that was once human a broad variety of
environments open up including that of deep space in fact if the speed of the
calculations being performed by a formerly human computer are a concern
the colder the environment the better but would humans as technological beings
even care about what their actual physical environment is like would earth
still matter we don’t know yet but it may be that the best environment for a
technological human is a total virtual reality that’s superior to anything that
exists in the real universe why pay attention to this universe when a
digital utopia can be created that better suits the human condition
so here the concerns for where we would be most comfortable depend more on
efficient calculation and massive energy production to keep it all going rather
than the concerns of suitable atmospheres and warmth number-3 improved
earth one of the things that advancing technology allows us is greater control
of the circum dances earth finds itself in within the
solar system ultimately we will be able to essentially improve earth by gaining
greater control over certain risks such as that posed by asteroid impacts in the
past earth was not nearly as Clement as it is today
and in fact early in its history could not support life at all and was subject
to constant bombardment asteroid impacts can still happen and with technology we
can deflect or even destroy problematic asteroids but in the future earth will
eventually become uninhabitable again but not necessarily so if we develop
technologies to literally move earth or move somewhere else
as the Sun brightens and eventually becomes a red giant this is not as
far-fetched as it might sound by orchestrating asteroids to pass by earth
and provide a small but nonzero gravitational tug on the planet over
very long periods of time on order of hundreds of thousands or even millions
of years the planet could be migrated to wherever we want so to some degree we
could hypothetically improve our world by giving it longer life in a changing
solar system or protect it by mitigating planetary risks like asteroids or even
building orbital sunshades to mitigate its growing luminosity number two better
than Earth Earth is a wonderful world located in an amazing solar system that
all happened to allow conditions that have resulted in the rise of life
intelligence and a civilization in a way human civilization for all its faults is
still an encouraging indication that other civilizations could exist in the
universe and often we imagine them as being more advanced or more enlightened
than we are that may or may not be true but Earth is not necessarily perfect
while it has the conditions conducive to the development of intelligent life
it can also be subject to conditions that might cause intelligent life to go
extinct such as the aging and eventual death of the Sun or asteroid and comet
impacts but in the end if we stay in this solar system the conditions of it
will long-term likely force us to look elsewhere for habitable worlds and while
nothing in this universe is going to be perfect
including the universe itself which will eventually become inhospitable to life
in its own right there are some cases where we might find worlds better than
earth that could remain habitable for far longer of a period than this planet
could one factor would be stellar types the Sun is a type G yellow dwarf that
will eventually expand into a red giant and finally settle down to be a white
dwarf while there are hypothetical ways to
keep earth or at least some body in the solar system habitable during all three
phases it might be better to just inhabit another star system entirely
that will remain stable far longer than this one will this includes the type K
orange dwarfs and type M red dwarfs both of which live far longer than our star
and they’re happily far more numerous than any other kinds of stars in the
Milky Way so as far as long-term human survival is
concerned there may be worlds located in perfect sweet spots within the
habitability zones of mature red dwarves and orange dwarfs that might yield
planets better than earth if we as humans tweak them with terraforming
number one artificial worlds and habitats the case can be made that only
humans know what’s perfect for us our own planet can at times become
unpleasant or even uninhabitable but being human we can also envision
technologies that would allow us to alter a planet’s climate or even create
a completely artificial environment that maintains ideal conditions for human
life we already do this to some degree with air conditioning and heating but on
a planetary or even larger scale we could do this with far larger amounts of
space than we have here on earth the first such option would be a terraformed
world a natural planet that we have used terraforming techniques to alter to make
for a better environment but that’s not the only option it’s also hypothetically
possible to build megastructures and even artificial planets that can be
inhabited by humans and maintain a perfect environment for us
these include Dyson spheres around other stars or partial variants of that ideas
such as Larry Nivens Ringworld but also enclosed rotating habitats such as
O’Neal cylinders that make use of centrifugal force to produce the effect
of artificial gravity such an environment could be perfect for long
term human habitation thanks for listening I am John Michael Gautier

  1. Hey Mr. Godier, crazy theory to toss your way…what if Dark Matter is the remains of previous universes? I mean, it sort of seems like what the final state of matter might be after a heat death…any thoughts? I mean, nothing says there wasn't something before our current universe, so…

  2. Apart from Earth, the places most suitable for people in our solar system are 50 km above the venusian surface and Saturn's moon Titan. If we colonze any other planet or moon, we'd probably have to live in underground bunkers due to solar radiation and a lack of breathable atmosphere. If we want to live above ground on the Moon, Mars etc. Artificial magnetic fields and airtight, self sufficient domes and pyramids would likely be essential. Spacesteads AKA a rotating space habitats could be constructed to provide Earth like conditions, complete with villages towns and cities, plus farms and some more " nature oriented " areas like forests and parks, in addition to lakes and rivers for good measure, and to provide water based recreation as well as or in leiu of, swimming pools. Spacesteads may be our best option for living beyond Earth, we could taylor them to fit our needs and desires. Want a tropical utopia in space? That can be done with enough resources and technology. An Arctic style winter wonderland with skiing, ice skating etc? Ya bet it could be done! An orbital plantation? Sure! When we get the resources and will power to get civilians to be able to live, work, play and vacation in space, which hopefully will be in the 2020s, then orbital spacesteads will become possible and desirable!

  3. I'm a bit skeptical about that last Dyson sphere graphic. A sphere 93,000,000 miles in radius but only 3m thick? Probably more fragile than a soap bubble.

  4. #7 is bullshit. Ignorance is hell and that which does not directly affect us is still meaningful. Intensely so if it might help us to survive the death of our universe or contain dangers to our existence. The moment we accept or embrace our ignorance is the moment we throw in the evolutionary towel and become technologically advanced cave men, waiting helplessly for extinction and blissfully getting progressively more stupid until we are become our own worst enemy. This era would be one of the worst times to live, especially with a lack of FTL technology. Are we sure this guy didn't just pull this one off HIS list?

    Addendum: why pay attention to the real universe when a virtual one is better? Because the real universe will eventually KILL US. A virtual one won't.

  5. If FTL travel follows the laws of causality (which it must, if we want to take it seriously), it won't let you explore what's beyond the cosmological horizon.

  6. Question: Being that the universe is heading toward maximum entropy, I'm curious at to what happens when it eventually dose hit. Is everything down to the smallest possible particle going to be perfectly spread out throughout the universe and hit 0k. How is this not a violation of the Heisenberg uncertainty principle?

  7. We humans are great at harnessing the forces around us. Could you make a video on hypothetically harnessing dark energy to travel beyond the visible universe?

  8. I don't know if I'd like the idea of a Dyson sphere around our solar system. I'd miss looking up at the stars.

  9. Maybe the best 10 places are: 1) Earth 2) Earth 3) Earth … you see these facts? I love research in the universe and creating new human habitats. But we should never forget, that for the nearly 8 Billion people on Earth "this is the place we make our stand" (to cite Carl Sagan). I love your channels – and would like to see you reflecting this fact. Compare the effort we will need to make any of the other places acceptable for human beeings – and the deficiencies these will still have (go hiking in the mountains in the weekend?) just underlines that we should "cherish the pale blue dot, the only home we have."

  10. Wow… John I love your voice however…. nothing personal to the other guy.. . But I just couldn't listen to him…

  11. Number 7, while probably true, seems like a chunk from an entirely unrelated video.
    I kept waiting for it to connect to the topic at hand… only it didn't.
    Bit of a jarring pothole to encounter when we're used to the buttery-smooth content that John gives us here.

  12. supercool collaboration.. thanks for the great work an my new top 10 channel to listen too. Subscribed immediately to Paul sutters channel. 👍👍👍

  13. Before I was this video, I am going to say that the list should be one and the one should be Earth. Humans do not belong anywhere else, nor should they attempt to go anywhere else. If we want to explore beyond Earth, we should send robots. Humans need food, water, oxygen, gravity, waste disposal, a very tiny temperature range, entertainment, other humans, and many other things. Humans are also emotionally unstable, jealous, selfish, fearful, irrational, and weak. We are NOT a good candidate for space explanation. We are one of the worst. But, what we have, is the intelligence to build what we are not.

  14. I have been curious why brown dwarfs are never considered an option. Sure it doesn't produce light, however it does have lots of material present for say fusion reactors.

  15. JMG, idk if you were a fan, but i was saddened to hear of Art Bells passing. You would have made a fascinating guest on his show back in the day. Thanks for the fascinating programs.

  16. Your voice puts me to sleep at night I love it ur awesome bro. We should get drunk sometime and u teach me your knowledge

  17. To the 12 thumbs down: how could you not like this video? The fact that you watched it shows that you must have some kind of initial interest in this subject. Perhaps you are religious and it somehow scoffs in the face of your God that we as humans will one day have to save ourselves instead of relying on a fairytale to save us. I'd love to know your reasons. Replies are most welcome to help me understand. With that said, thank you John and Paul (ironically your names are both biblical), I really enjoyed this video.

  18. John Michael… with your great radio voice and interesting subject matter, you could start a late night talk program (M thru F) and I bet you could pick up all of the misplaced Art Bell fans out there.. now that he's passed on. I for one would tune in regularly !

  19. Future civs could be castaways from universe expansion, like species trapped on distant oceanic islands.

    But if you advance soon enough you can colonise other galaxies before they are too far away, like a species colonising entire continents before plate tectonics isolate you. Mind blown, epic video.

  20. its kinda amazing, that you can survive without a space suit on venus at 50 km height, and if you just lose or your oxygen tank leaks, you can safely hold your breath for maybe a minute

  21. Life that can exist as habitable zones on planet Venus , exoplanet Trapist 1 d with the hunt that there might be liquid waters , atmosphere favourable with oxygen ,Europa and Anceledus the ice shells Moons of Jupiter and saturn with the discovery of waters inside the crust. , Super Earth better then our Earth , Virtual reality technology to alter our own biology ,Improving our own Earth by protecting from asteroids impact that may occur in future or shifting the Earth to a safe place as Sun will become a red giant in future .Interesting video viewing the top 10 places in Universe to live.Thank you Sir Paul and Sir John for sharing the knowledge.

  22. the mankind should have first the information about the chimical content for a new habitable planet. If this new planet have the seem life signature like auer earth we could trravels there to create a new humans colony of this new planet!

  23. John, you and isaac are awesome i love listening to you both. Paul you were fine but im a creature of habit they sound more natural (no offense).

  24. And just throwing it out there but anywhere life isnt present now i believe e have the responsibility to spawn it.

  25. Imagine being on a floating city in the upper Venusian atmosphere, as the city’s mechanical system experiences catastrophic failure due to accident or sabotage, and slowly sinking into the clouds to your horrendous doom…

  26. Hey who is this other guy? Take over? Whoa? He wants your followers..haha having fun…may be true.

  27. Given that distance is a huge problem is time travel likely.All those darn UFO's are strangely similar in design.The f150 of the year 9595 so to speak.Thank you great show.

  28. I have always thought that when the our Sun eventually Expanses over time, I'm sure the goldie lock's position will move with it, moving outward towards Mars and Saturn's Moon's eg: Enceladus, also Jupiter's Moons Ganymede and Callisto, Europa will have a run away green house affect, with the Sun expanding which mite cause a Earth 2.0 on maybe more than 1 Planet also the Moon's ect, and not only have a Earth like atmosfear but a totally viable living conditions for the future human race.. #TheSunsGoldieLocksPositionsEuropaEnceladus

  29. a Dyson sphere would drowned the planets with lethal radiation. The heliosphere would back up and be more hell. IMO

  30. What if there's an advanced civilization at the center of the galaxy where the residents thrive on the energy output from those densely packed stars?

  31. We have some submarines that can survive in the crushing depths of the abyssal and hadal zones of the Earth's oceans. We could scale up that technology to make living areas and colonies. Settling just below the ice on Europa, Enceladus, or Triton; or moving colonies deep in their oceans would be better, than having to deal with hostile conditions of the vacuum of space on the surface

  32. 1:30 – i have the feeling that we faster colonize Venus… we will also terraform it. It has magnetic field, atmoshpere could be converted easily and it's same size as Earth. I think scientist should start thinking aobut travelling there than to Mars. First we could station there stations that would produce the oxygen out of carbon dioxide that is in the atmosphere of Venus. This is very realistic to colonize Venus is a few hundred years.

  33. 10 best places for humans in the universe
    1: a place with water and air.
    2: a place with water and air.
    3: a place with water and air.
    4: a place with water and air.
    Should i continue??

  34. Regarding the idea of colonizing ice-shell worlds like Europa: Why drill all the way down to the ocean? Just make an ice-cave and live inside that instead. As a bonus, if you treat the ice properly, you wouldn't even need glass to form the roof, because you can make optically-clear ice that is strong enough to retain an atmosphere and let sunlight in.

  35. Mr. Godier, I like your channel a lot but this colaboration seemed a bad choice. I'd rather hear you alone. The voices together are so incompatible that it creates a disruption that is counterproductive. My regards.

  36. The Mediterranean and Southern California, clearly. Well, apart from all the people living in Southern California that is. if it wasn't for them, though….

  37. Also, we can't even live here anymore now when unassisted by technology. Remove "civilization" and about one in ten thousand will be able to feed and house themselves to survive past three months, If that. This is the trap of civilization and why they always collapse. They look advanced and invincible, but each individual is more helpless than before if anything goes wrong. Which it does, frequently.

  38. Great vids but please don't contribute to the extinction of the word "fewer". It's a fine and streamlined word. People mistakingly say "less problems, less ice ages", etc. but the word is "Fewer" ("fewer ice ages, fewer problems", etc.) Thanks

  39. How many times have ppl accidently renamed or rediscovered the same planets? Given that the planets move around

  40. Terra forming would include having to keep up with the "up keep" with terra forming as the planet would eventually return to it's original status

  41. Best places for people in the universe

    1 – Earth's surface, except a few desert and arctic areas

    2'- Underground on Earth, though not too far below ground

    3 – Venus about 50km above the ground. At This altitude, Venus possesses temperatures and pressures akin to those of Earth

    4 – Proxima b or c, assuming these planets are habitable like Earth

    5 – The Trappist 1 planets, particularly Trappist c, d and e.

    6 – Saturn's moon Titan. While it's ultra cold and the atmosphere not breathable, Titan has the right atmospheric pressures and negligible radiation.

    7 – Mars. Sure, the atmospheric pressures of Mars are far too low and there's a little radiation problem on the surface, but these things are workable, plus there's a possibility for terraforming!

    8 – Ganymede. As the biggest moon in our solar system with its own magnetic field and an orbit of Jupiter just outside the planet's main radiation belt, Ganymede is pretty much the best place in the Jovian system and likely the easiest moon to terraform!

    9 – The craters and lava tubes of Luna and Mercury. Mercury and our moon don't have very hospitable surfaces, but underground, it's an entirely different story! These craters and lava tubes would be relatively easy to dome over and pressurize, and they'd offer kilotons of protection from the radiation and temperature swings to boot!

    10;- The underground oceans of ice moons and minor planets. About as habitable as Earth's ocean!

  42. so far every planet we're been able to properly study there has been both no life and a very good reason there is no life…. but it would be interesting to study a planet that at least should have life on it, even if it doesn't.

  43. Forget about liquid water and all of that. A planet needs to have an unlimited supply of 6' horny blond Swedish girls, plus grilled salmon and white wine or I'm just not going.

  44. Sorry but how tf would we survive if we migrated our planet to a different solar system? All life in earth would die, plants, insects and animals, everything…

  45. Worst place in the universe to be if you’re an intelligent human being: a Donald J Trump rally.

  46. We search for Earth-like planets for the obvious reasons of finding environments where life as we know it might be evolved, or that we could live there, etc. However, might there be myriad environments where some form of life would develop and prosper, forming some sort of intelligence in the process? Not only do we not know exactly what or how our minds work, neither do we know how life might arise in a vast spectrum of conditions.
    As always too, will we recognize living material or beings when we encounter such things?

  47. My only consern here is the artificial climate change made by mankind. We may not be here anymore (or be dragged to the stone age) by our own stupidity before we can leave Earth

  48. I think the impact with Thea in the early evolution of Earth may have been the reason why the Earth turned out like it did. I think planets like Earth are going to turn out to not to be that common

  49. #1 far away from humans and earth or people who like the kardashians and may I say you have a great voice. thought I was playing mass effect

  50. achieving a Type III Civilization on the Kardeshev scale would be the end game in the next 10,000 generations… maybe 100,000 generations, UNLESS you're a Judeo-Christian Zionist shill, then as long as Israel is the last-standing habitable zone on our planet, then humanity would have achieved its objective of freedom, human rights and democracy, God Bless

  51. No intelligent life evolved in the ocean? What about octopus and squid? At any rate they're intelligent for molluscs/invertebrates.

  52. The best places in the universe to be if you are a human .
    1. Earth
    The worst place in the universe to be if you are human .
    1. Anywhere that's not earth .
    I honestly believe that interactions with alien planets , even with exactly the same type of conditions we live in currently , would be catastrophic to us . There's no telling what kind of nasty little alien microbes could mix with our biology and kill us in horrible and fantastic ways . There's no way I'd be the first guy to take my helmet off . I would however be happy to be the guy to test the spaceship to get to another planet .

  53. Something i'd like to ask you, if oxygen feeds our brains, and o2 hasnt always been the main gas in our atmosphere, and the fact oxygen eventually corrodes and ends all life, it makes sense (to me at least) that there could be, on another planet, a gas or collection of gasses in an alien atmosphere that could, in theory, prevent the corrosion that oxygen causes?? In effect, cause life to be infinite, or possibly last much longer than oxygen does?? If such a place exists and space faring humans discovered such a planet, it would potentially start wars, or if we could emulate such a fountain of youth gas, couldnt we terraform other planets with said gas?? I know its unlikely but the universe is big, and like you said, some planets may be better than Earth for us! Just a theory, i have had a glass or two of red wine!!

  54. Wouldn't a super earth have many times the force of gravity making it most likely impossible for humans to live on it? I would think a 100 lbs person being 500 lbs on the super earth would make it impossible for that person to even stand .
