is there a possibility of another planet in the universe where life can exist?

Answer 1

Yes. Although no true science can give a 100% answer yet.

Consider the Drake equation, where the probibility of life is based on a series of math variables.

Even modest answers for these variables produce incredible results... although life may be possible in other reaches of the cosmos, the ability to communicate is in the very distant future (if ever).

Answer 2

well, so far we still have pretty poor planet detection methods, and we've started just 10 years ago, and we already have over 150 planets detected.

It increasingly seems that most stars have at least a few planets around them (natural part of the formation of the system). It also seems that most systems look like ours i.e. smaller rocky planets closer to the star, then a couple much larger gas giants.

You have roughly hundred billion stars in our galaxy. You've got hundred billion galaxies in the "known" universe.

It thus would seem pretty likely that you'll have many, possibly millions, possibly more, planets with all the right conditions for life. And if life evolved naturally based from basic chemical properties of elements, and given that those elements are the same across the known universe, it seems very likely that there are numerous planets with life.

Now whether they harbour intelligent life, or simply if we will ever know that it is there (given the huge distances, and the poor means of communication we have), these are two different questions.

Answer 3

If we exist, there should exist other civilizations, and we should not be the first; some should be older and much more technically advanced than we are. If space travel is possible, then some of them should have visited us by now. Iit should only take a few million years for an advanced civilization to explore our whole galaxy. With potentially thousands of such civilizations (Drake equation), we should be swimming in extraterrestrials. If not, either there is nobody else, or the rare civilizations are very far apart, or interstellar travel is impossible, or technological civilization lifetimes are too short.

Answer 4

Yes. Did you really think we were special? The human race has come up with all of these ways to believe that we are special. Sorry, we are not. This type of planet is very common and carbon based life forms are very common. We are in a common solar system in a common galaxy, surrounded by trillions and trillions of other galaxies. Though... we may be one of the only life forms who actually lasted long enough to ask these kind of questions and look up into the universe and ask where we came from.

Answer 5

We've already identified planets very similar in nature to earth, that are capable of sustaining life similar to our own. That being said, the universe is so vast that literally millions or billions of similar planets are bound to be out there, but we haven't discovered them yet. Add to that the likelihood that different forms of life can be supported in weird climates that we also don't know about. Yes, life on other planets is almost a certainty.

Answer 6

It's almost a certainty, there are billions of stars out there. Each star is a sun, and each sun has a few planets. This means that there are billions and billions of planets out there. At least one planet must support life. There could be people out there just like us wondering if there's life on another planet, like you. There could be life that is different to ours, they could have evoled to live without air or anything. The only bad thing is that they are probaly light years away from us and so we will probaly never be able to find them. Hope this helps.

Unless they find us first.????

Answer 7

The famous drake equation in astronomy estimates that there are between 10 and 50 intelligent civlizations in our galaxy alone. So in a nutshell, the most scientific and educated guess in science says there are at least 10 civilizations in our galaxy that are at least as advanced as our own. This is a statistical probability based on the best information available to science today.

Answer 8

if you believe in math, statistics will show that the chances are about a trillion billion to one. life cant be supported unless circumstances are perfect. i.e.-water must be in all three forms (liquid,solid,gas), planet must be a certain size or gravity will crush everything, must have an atmosphere to protect from fatal cosmic rays and debris ect.
if god is responsible for life, then yes, if he wants to create more he could, if evolution is responsible, then its a miracle we even exist (and can comprehend our own existence no less).

Answer 9

I believe so, and this is my reasoning. Earth is such a pinprick in the universe, how can we be alone?

We dont even know half of what is going on with our own planet and our own environment. How can we be so arrogant to think that we are alone in this vastness?

Answer 10

Well, its a mathematical certainty if we assume the universe to be infinite in size. Now within any distance that we'd ever encounter them- that's another matter.
