Is There Life Anywhere Else On The Universe ?

The fact that Pluto was taken off the list of planets had me thinking about other planets and other galaxies.
Surely somebody like us will be inhabilting one of those distant galaxies. If life started on the Earth, then it should have started on any other planet near a start like the sun. And there would be many such planets.
What sort of people world they be ? Would they also have houses, electronic stuff, nuclear weapons etc. Would they be more advance than us ? Communicate by thought. Travel through time etc. Would they travel through space and find us. Because there is no chance of our finding anybody in the near future. If somebody else is living on this universe they have to come and find us out.
Lets wait for them...

I really like this subject. If you sit back for a moment a realize the shear size of the universe then you will know there has to be life somewhere. Each star you see at night is a star like our sun. Each one having a groupe of planets. And they are only the ones in our solar system. then you have our entire galixy. then you have all the hundreds of billions of galixys in the universe. There has to be some sort of like on at least one planet when you take it all into context.

Well yeah I mean cmon so many planets outside our Milky Way I mean there must be other life. What is the chance that there is none? Very little I mean we got life so can't other planets.

Well, topics similar to this one have been discussed many times. I don't know whether we'll ever get to find out whether or not other planets have any kind of life, but I wouldn't mind betting that that even some of the nearest planets, such as Mars and Venus (Probably not venus as it's closer to the sun, so might be quite hot) may have some kind of life.

I agree with what is said in the above posts, there are millions of different stars, planets and galaxies out there. Obviously, a lot of them are pretty much dead and haven't got the correct conditions for a living thing to be able to live.

Maybe when scientists are investigating other planets and sending space shuttles to them, they might accidentally discover some form of life. This would be on the news I guess, so we'd find out if there was some kind of life. Space is such an interesting topic to discuss and think about. If galaxies and planets etc didn't exist, we wouldn't exist, so we wouldn't be here to speak.

If we ever found people, they would have to be totally different from us. Maybe they are used to living in -20 degree weather all day (finally we could have a use for Antartica). Either them or us would have to adapt to each other. Plus, would we try to move them unto our planet or theirs? What would the people be like? I would imagine that they aren't as educated as us, but who knows? Maybe there is a whole different place with a different Bible and King and they have their own solar system? It's a creepy thought, but one that must be considered.

I think we are mistaken if we think that there is no life in other planets or galaxies just because of temperature and the lack of water or oxygen.

Think how we die in water without artificial support and how fish die out of the water.

Think how plant use CO22 and produce oxygen and we use oxygen and produce CO22.

Think how polar bear are living in that atmosphere.

Think how we have blood pressure and the plants has another pressure.

Think how cows eat bush to produce milk and meat. Can people is living on the grass only?

Can Lion and other meat-eating animals survive on grass?

All this conclude that creator could create another type of life . I think all these planets and galaxies are not only for one life which is our.

Well as far as water goes, Mars has it underneath it's rocky surface. It also gets extreme heat, when on the right angle to the sun so that is a formula for bacteria, which eventually evolves into other creatures. The problem with it though is there is no food for them to eat...

Food is not really a problem. I remember reading once somewhere in this forum that deep in the pacific ocean, there are microscopic organisms that do not rely on sunlight and, instead, feed on noxious stuff like sulfur or metals, I dunno exactly. They get energy from the heat of deep ocean volcanic vents. I don;t see any reason why there can't be any such forms of life like this.

Jupiter's moon, Io, for example, has a more than healthy volcanic activity. I'm not sure about groundwater in Mars, though, although water can remain liquid on mars, I think.

Yes I know I was just chating with a guy who is 1000 light years away from us. lol

Very good point raised by Kasm, we know that atmosphere is ecessary for life and all our prediction that life is not in venus, mars etc. is based on this fact, that they cant have life supporting atmosphere.

But life can be of any form, it is not necessary to be originated from bacteria, but can be of some new form, who knows. I think some sort of life can be possible in Sun too, as Husker said life can be in -20 degree weather then why cant in +millions of degrees.

So some day will come when an UFO will land in earth, and not only 2-3 people but the whole world can see them, I wish this to happen in my life time.

I'm a member of an amatuer astronomy club in the area in which I live. One night the main man was telling us the possible number of stars in the universe. He held in his hand a plastic container holding 4 grams of sand. He spread them out and counted 1/4 of the sand grains which were 500. the total numer of sand grains were 2000. He then said that a two (2) tonne truck can hold 500 000 000 grains of sand. Now imagine a row of two tonne trucks all loaded with sand bumper to bumper around the equator. Every single grain of sand is a star. We are looking at very large numbers now but that is still a very small number in terms of the universe. Each star may have a body orbiting it (or a planet). It is strange to think that some people actually admit that they think this is the only planet that has life. Of course there is life - you would have to have a very small mind to think so.

take a minute to think about this- life is VERY fragile! the only reason we exist is because we are EXACTALY the right distance from our star (the sun) for a number of variables to be just right for life to form:
its not too hot or cold, so water stays mostly in liquid form (water is the universal solvent!)
its the perfect distance for the perfect temperature for life
the earths orbit is perfect - not too fast, not too slow, not too big, not too small

also, we lucked out and got a planet that just happens to have oxygen, carbon, nitrogen, and hydrogen (the 4 organic elements); these are key to creating carbon chains, which form proteins, which then form deoxiribonuceic acid --- DNA!!!, which through adaptation, and other evolutionary processes evolves into more and more complex life (like us!)

next, with the varitey of newly discovered exoplanets and the sheer number of stars in our galaxy, then with the sheer number of stars in the UNIVERSE! the probability of finding a star that supports a planet similar to ours is pretty good!

so is there life, consider how fragile life is, and the perfect situation it requires to exist and you can see the possibility.... having said that, evolution, and stellar formation takes a long time! and our universe is estimated at 13.5 billion years old (that means it took that long for US to evolve!) so the final answer, and it is purely opinion at this point of scientific exploration and knowledge; but i think so. one last thought- IF it does exist, its probabily not just like us, at the very least, its probabily just a patch of weeds growing on some far away planet in some galaxy not yet discovered! like i said, its fragile, therefore rare!

That is why we as Earthlings continue to use science to explore the universe in hopes to find life that is just like us or even more advance, however, in order for Earthlings to truely explore the universe we nned to band together, and let go our pride and put all our sources together in order to create a space that is fast like the Enterprise in Star Trek, powerful defense capabilities like the Death Star in Star Wars,, and cost effective to not bankrupt the world 100 times over. Scientists specular that when asteroids were crashing into earth a few billion years ago, that one of the asteroids carried the human genome, and when it crashed into earth the process of human life would begin from there. Of course, it is the tales from science fiction stories that made us want to keep on exploring and seek out the answers to our existence, and the existence of the universe as well.

If there are to be any signs of life on another planet. I would believe that the lifeforms would be completely different to us, considering the different gravity, and living conditions on another planet. For example, the moon, instead of walking you jump. Other planets, may have varied temperatures as another example, or there may be lack of (or no) air on a particular planet, yet a lifeform may have other uses to stay alive.

i for one is believes in God and science at the same time.

many people believe that science and religion cannot coincide with each other but i think this is wrong.

there is no verse in the bible that tells us that there are no other beings but tells us we are special. ( can anyone verify )

i think also that an analogy: its so big there's something in it is false. one cannot say that the universe is big because we cannot see the other side.

ok so i am ignorant and stupid and some other stuff that i don't believe that there other intelligent life out there. and science is really the answer to everything then

how come everyday their are breakthroughs that contradict the old knowlodege that we hold true.
how come astronomy is been here for thousands of years has still no answer to why the universe is expanding, how come it is expanding, where it is expanding into, and how really big the universe is.-- (don't tell me the calculations made by scientist that
predicts the number of stars is true. then your calculating the prediction of numbers by predicting the variables and in math that cannot be)

how come evolution is so believed that even if its logic about the giraffe is wrong we still hold evolution as true. ( give the missing link first then i will believe your evolution. one of the stupid analogy of scientist= A and C is so the same so there should be a B in the middle)

The question is: Is faith part of science? Do scientists go around trying to prove what they believe in? As basically many have been saying, they believe that there is life out there besides what is on earth. If scientists are using whatever they can to try and prove such a thing, then they are running off of faith. But will their faith fail them? Of what evidence do we have to know that there is life out there besides what is on planet earth? Sure you can give out a lot of reasoning as to why you believe there is life "out there," but how does that go about in proving that there is life "out there"? It only brings more people to(wards) the faith.

The universe is infinitely big, and we've only been able to explore about 0.005% of it.

The second half means that we know the actual size of the universe and that it's not infinite. Which means it contradicts the first half. So, how big is the universe?
