if there are other galaxies???

Question

then are there other planets? do they have life? will we ever know?

Answer 1

Hello,
From a scientific standpoint I can't confirm the existance of life on other planets but I can confirm this. Scientists have discovered planets that have similary temperatures and atmospheric conditions to earth. Do I think there is life on another planet somewhere in the universe? I am very optimistic about it if that answers your question.

Answer 2

To expand a little on what Steve N said. We live in the Milky Way galaxy which is pretty average and has around 100 billion stars. There are probably at least that many galaxies in the Universe so there are a lot of stars around. Some of these stars might have planets and some might not. Some of the planets might be habitable and some might not be. You can see that there are a lot of unknowns in this question. You may want to read about the Drake Equation which attempts to calculate how many advanced civilizations there are that have reached a stage where they could possibly communicate with other planets. Drake I believe was the first guy to try to hear radio transmissions from other civilizations and of course failed. There is currently CETI (Search for Extraterrestrial Intelligence - originally I think they just scanned radio frequencies from space looking for patterns that might represent someone trying to communicate but now days are a much larger outfit doing other things as well since listening to static for almost a quarter of a century gets a little old pretty quick) and I have included links for that. You may help them if you want by letting your computer help process the data they get. It is possible that there is life, since there is life on this planet, but it may take other forms than what we are used to. And we may never know since zipping around the galaxy like on Star Trek or Star Wars or Stargate is just not possible (the laws of physics dictate this and you should read up on these so you will be informed).

As of this time no other inhabited planets are known of. Life forms have not been found on the moon, mars or in any meteorites that have been examined. It is known though that clouds of amino acids and other chemicals that form the basis of life on earth exist in space.

Answer 3

Yes, there are other planets. So far, we have found 248 planets around other stars. Yes, 248. And the number keeps growing.

We do not know if these planets have life, but a few are likely contenders for hosting life forms, including the famed planet Gliese 581 c, which was discovered in its stars "habitable zone."

The habitable zone is the zone in space where the temperature on the surface of a planet is just right for liquid water to exist. Earth lies right in the middle of the Sun's habitable zone.

We will probably know if life exists elsewhere in space within 50-75 years. That means we should be around to hear about it!

I am hopeful that humanity will expand into space, and along the way will find exotic and beautiful life forms as varied as the millions of species on Earth.

Answer 4

There's no reason to believe that either our galaxy or solar system is particularly special or unusual. There are many other galaxies out there that are forming stars like our own all the time, and there are planets forming with them. We will probably never know factually the answer to this question, but I believe there are just as many planets in spiral and irregular galaxies like ours that have been forming stars at a steady rate over billions of years. There has been so far more than 200 planets found orbiting stars other than our own, and it's a matter of time before we find Earthlike planets with some sort of life living on them.

Answer 5

We've already detected a couple of hundred planets about the nearby stars in our galaxy; We've no doubt that there are planets orbiting stars in all the other galaxies as well.

Do they have life? Without proof, hard to say, but I feel some would *have* to.

Will we ever know? I think we'll worry about finding life in the Milky Way first, and it's hard to think about that far into the future where we'd consider looking in other galaxies.

Answer 6

Read Carl Sagen's The Cosmos. There are billions and billions of stars. The earth was created by the Big bang, there is a third dimension it is baed on String Theory. The Earth was seeded by ailens millions and millions of years ago. New Planets are discovered all the time. There are meteors, cosmic showers, comets, stars go through a life cycle: White Dwarf, Red dwarf, black dwarf than supernova.

Answer 7

There are billions of other galaxies. Trillions of other planets.
And some of those have life. Carl Sagen predicted that there are between 5 and a million intelligent civilizations out there

Answer 8

galaxies do have other planets, and it's possible the planets have life i don't think we'll ever know.

Answer 9

Yes, there are other planets. Some of them may have life. But we may never know. They are so far away!

Answer 10

Research the Drake equation and decide for yourself. That's what's really most important, anyway, as far as your question is concerned. We may never know for sure in our lifetimes! Support SETI.
