Alien planets...?

Question

The universe is essentially infinite, so the probability of there being advanced life (aliens) out there is very high. Is anyone else absolutely infatuated with this fact? Aliens wouldnt necessarilly be little green men, but imagine coming across a world that could not be more foreign to earth. It could be 10 times bigger or smaller, all differently shaped land masses. Where are the important and historic population centers of this planet? Some of the greatest heros and leaders of its history? The possibilities are endless, it would be like entering a sci-fi movie. Anyone else share my enthusiam?

Answer 1

Why goe so far? They apparently theorize there are whale like creatures swimming in the methane lakes on Titan right off Saturn. Maybe if true they are intelligent Who can say? One thing is sure for now if we find any life we can truly research it would be on the moons within our own solar system.

If you thoroughly meditate and contemplate the above, the best and most reasonable solution is that we are the ONLY show in the town.

Sorry kid... the craft are just New World Order vehicles and what you call "aliens" are just  extradimensional beings or what some call "The Fallen" (Mr. Mitchell knows this):

Answer 3

I share your enthusiasm, but would like to point something out...

A planet 10 times the size (note, not mass, but size) of Earth is a gas planet, like Jupiter or Saturn. I have little hopes for life on gas planets.

A planet 1/10 of the size (note, not mass) of Earth is comparable to large asteroids in our solar system. Such objects lack the mass (assuming reasonable density) to hold on to an atmosphere to support an intelligent form of life.

More reasonably, perhaps 1/2 of the size of Earth, to twice the size of Earth, might have intelligent life.

Answer 4

i feel ya the universe IS endless and there is no way were the only liveing things in the whole frekin thing, yea there has to be extreterrestrials

Answer 5

heres my opinion  that a planet even the size of Jupiter or Saturn if it had the mass to support life like ur earth  and wasn't to cold or hot then yes there could be life there. we haven't seen a planet yet that is big that has that much mass all we know for sure is that our giant planets will not support life as we know human life to be

Answer 6

Definitely! I absolutely AGREE with you.Nothing's impossible,absolutely nothing!I think "aliens" DO exist.I don't think they're those green little men,i think that this green little men thing was a made up story.....The real ones are prolly somewhere up there in the universe or something,nut i doubt they're green and all that.U know what?I wouldn't be surprised if they looked just like us.lol And i wasn't joking with this.They could very well look like us,or just look different,i have no idea,but certainly they're not green.lol One thing i know for sure,we're NOT alone in the Universe!

Good stuff, but the Universe isn't close to infinite.  It's about 13billion years old.

And many of those planets are well past life-giving and many well before, so you should look at a standard deviation.

Even a high standard of deviation would give you  six to seven billion year timeline for life-bearing planets.

Then you have to deal with multiple-suns tearing at planets, planets too cold or too hot, etc, etc.

There's something called the Drake equation that tries to take all these variables into account.  The problem is if one variable is guessed at wrong, the percentages of life swings dramatically.

And assuming life is in multiple places in the universe, how do they get here?  Or we to them?  Statistics would suggest they'd be visiting us a trillion times before we get off this rock.  I hope I've taken a shower the day they introduce themselves.

Answer 8

The universe is not infinite, but you're right that it is vast.  Gothika is also right in that the range for planets that sustain "life as we know it" is somewhat smaller than you estimate, but it's still very large.  Even gas giants could harbor some sort of floating balloon-like creatures, as Carl Sagan speculated.

I recommend you read up on the search for exoplanets.  It really is a fascinating field, because it demonstrates so fully the immensity of the universe.
