Do you think that we'll be able to find another civilization in the space?

Out of 10,000 Billion Galaxies out there. No Doubt there is something out there.\n\nEarth will contact something...but not in our lifetimes.\nI even believe there is another planet like ours out there somewhere.\n\nWe would be very naive to think we are the only intelligent planet in the entire Universe.

While I agree with other people here that we should take better care of our planet, eventually the Earth will be destroyed.  Even if all comets and planet-killing asteroids miss us, the sun will eventually expand into a red giant and engulf the Earth.   Though that isn't likely to happen for possibly another billion years, it will eventually happen.\n\nThat being said, the more planets that we as a species inhabit, the greater our chance of survival.  Especially when we consider the possibility of colonizing other worlds in distant solar systems.  The endeavor will not be an easy one, and is indeed not possible at our current level of technology.  However technology may eventually advance that allows us to traverse great distances of space in but a few moments, perhaps through the creation of artificial wormholes.  Maybe we'll be lucky enough to see it in our lifetime.

If there is life on other planets (outside of our solar system), the odds of ever finding out that there is life there is infinitely, ridiculously small. The next-closest star to our solar system, Alpha Centauri, is just a shade under 4.3 light years away. Even if someone or something from a planet orbiting Alpha Centauri had the ability to travel the distance between our two solar systems and not die of starvation or, if they were able to achieve near-light speed, keep their molecular structures from becoming severely distorted, they would have to make an amazing pinpoint shot to hit Earth. Even if there is "intelligent" life out there, I think it's impossible for us to ever make any sort of meaningful contact with it. Anyone who has ever shot a rifle knows how just a fraction of a degree can determine a hit or miss on a distant target. The odds are that much more exponentially outlandish if we imagine interstellar travelers getting lucky enough to find our planet and solar system out of all the others out there, no matter how "close" we are.

Unless we do something, life on Earth will most likely not exist once the Sun supernovas. If 'we' can figure out how to live elsewhere by then, ostensibly the galaxy is our playground. Big challenges involved though. It seems it would make sense to just move the Earth. Why not? 'we' could move the Earth, don't you think? What part of the galaxy should we move to. I'm sure we'd mostly like to stick around the Sun and it's leftovers, but we could choose to ride the Solar wind to another star. (Don't worry, humans won't have to do the hard labor of converting the Earth into a space ship with temperature and climate control). \n\nIt'll be fun. Like a road trip. Too bad we won't be alive. Probably no actual humans, either. I hope they're cool who/whatever they are.

Even though we can't prove it, the answer is yes. The universe has billions upon billons of stars. So even if our planet was like 1 in a billion, there still would be 8 or 9 other planets like ours. How advance the civilization is, we cannot tell. This is in reference to intelligent life. As far as microscopic life, there well may be signs of this in our own solar system. Scientist at NASA have recently discovered liquid water under only tens of meters of ice on one of Saturn's moons. Along with this, they also discovered a thermal heat source at it's south pole, which is spewing water 300 miles into space. So this heat source and water may be home to microscopic organisms that have adapted to the cold of the moon. Hope this helps.

I think it would be naive to think that we are the only intelligent beings in this vast universe. Of course it would continue to exist. And as far as anyone knows, the boundaries to this universe may never be reached by human beings. Also, you are correct in your statement that human beings will become extinct. I say this because we only need to look at the dinosaurs. Excellent question!

Probably find a ship graveyard.\n\nNo...for real...I don't think it is possible to reach the edge of the universe.\n\nPrint this out, then if it happens, you can say, "I told you so."  :)

Thinking that in an "infinete universe" we are the only planet with life is selfish and stupid...\nImagine: We are in an insignificant planet, at the corner of an small galaxy...\nI think is very probable that exists other intelligent life form out there... \nThe question is: How far away? Can we ever met them? \nI think they are far enough, so we won't have some kind of encounter with them...

Yes, we will discover other planets that also sustain life, and we will do so within our lifetime.  I do not mean that we will physically go to these planets but we will discover this by placing much more powerful telescopes in orbit around Earth.  There is a definite signature that we will be looking for and that will be the presence of Oxygen in another planet's atmosphere.  If a planet does not have any oxygen in its atmosphere then it would not be able to support life.  There was a time billions of years ago on Earth when there was no oxygen in the atmosphere and at that time there was no life on Earth.  We may not discover other intelligent life on other planet's during our lifetime but i am sure that we will discover other planets that are supporting at least plant life if not primordial single cell life as well.

if theres not i would be extreme surprised.  the universe is so huge that it would be ridiculos to assume or think there isnt.  even though we have only explored probably less then 1% of the universe we have still found planets that we think would be able to suport human life (remember not all life would have to be carbon based like us either) so even if there isnt a planet that we could live on some other type of creature might think its paradise.  the answer to your question is yes there is most likely life other then ours out there somewhere. although it would depend on what you mean by "life" if you mean intelligent life i still think yes there probably is although they have found fossils of bacteria on mars so technically that means there was at one point there was life in our solar system other then earth.

of course. As long there is a living thing outside space, they r aliens. The possibility is low but the no. of planet is almost infinity so the possibility increases.

With the nearly infinite number of stars out there, it is reasonable to expect that life has developed on another planet. However, we won't know for sure until we actually encounter that lifeform, and that may be a long way off.

Chances are, yes.\n\n90% of all solar systems are not in a circle so they can not support life.  Of the 10% that are left what are the odds that another planet is moving around a sun where it's not to hot or too cold. Even in our own little solar system there is only one.\n\nSo, if there is life elsewhere, we will never meet them.

It may well be!\n\nThe problem is that we haven't really looked. It's true that the probes we've sent around our own solar system have drawn a blank when it comes to life. Life as we know it seems to prefer a certain range of temperatures and habitats, and those conditions aren't all that common. But they do exist, both here in our solar system and (almost certainly) in other solar systems as well.

not in our solar system. \nBut you also have to remember that even if there is life on other planets, we are assuming that they are as advance as we are or more. Could it be that maybe they are in a pre-industrial era and have no means of space exploration?

First of all take into account that nothing is impossible ;on the other hand do you think we are the sole inhabited planet in so many Universes ? When there are millions of...Galaxies, contain ing millions of Stars and 5llions of Planets, why, some of them do\ncontain a logical life form....! And why shouldn't have been advan ced in a way to minimize distances and exceeding our civilization\n ???\n Do you think US Pentagon hasn't caught some of them,studied them and...manufactured replicas ? Do you think they'd come out\nrevealing people about their break through??????????\n Why not being tolerant and accepting-even-the-theoretically--im possible????\n (we'll all feel much better!)\n Ciao.......John-John.

This is a little hard to answer.\n\nFirst, we haven't found any.  So there's no positive evidence, so it's hard to be really sure. \n\nBut on the other hand, there are billions and billions of planets like ours, and it would be really weird if ours was the only one to have life on it.\n\nSo most astronomers think there's probably life out there somewhere.  I hope we find it.
