can there ever be another earth outside our galaxy?

Answer 1

Not one but maybe hundreds, thousands or hundred of thousands, who knows, our galaxy has billions of stars like our sun and most have planets orbiting, but our galaxy is not the biggest one, let's say Andromeda is much bigger that the Milky Way so you could imagine, only one star in that galaxy, Antares is a thousand times the size of our sun, we are not alone, because this life we have came from somewhere else in the form of cosmic dust, so I think there are plenty of planets like ours and maybe with civilizations much more advanced..☺

Answer 2

With the billions of different planets in billions of different galaxies there is an almost certain chance that there is a planet at least very similar to the earth if not identical. This is of course supposing the theory that the universe is infinite or that there are many alternate realities either one supports the fact.

Answer 3

I'm not entirely sure I understand what you mean by Earth. Is there another Earth exactly like this? If the many worlds interpretation of quantum mechanics is correct then yes, millions and trillions of them out there and new ones being created each moment.

If you only mean inhabitable planets roughly our size, covered in quite a bit of water and some greenery - then there might be hundreds of thousands of earth like planets in this galaxy alone.

Answer 4

I think it would be extremely foolish and conceded for us to think that we are the only lifeforms in existence. There probably is another planet out there that is very similar to Earth. Even Venus and Mars share characteristics with our planet. I'm sure there are other solar systems in the vastness of space and even in this very galaxy that have planets not unlike our own.

Answer 5

yes there could be a earth outside our Galaxy because there are millions of galaxies which can have solar system like overs and can have a earth although the people there may not be able to search us like we cant search them now.

Answer 6

In our universe there isn't likely to be another Earth, ie a planet exactly the same. However there should be plenty of other planets which can sustain life, a study or two have been done. See link.

Answer 7

Yes, in fact, there's probably billions in other solar systems in other galaxies. Trust me on this. There's billions of galaxies, billions of solar systems, and billions of planets orbiting other galaxies. THe changes of no other earth anywhere, would be about 1/10000000000000000000 there's definately another earth somewhere.

Answer 8

I know a known planet just past years. It's bigger than Earth but smaller than Neptune. It is the Kepler 22b. It is an Earth like planet than is found in Milky Way Galaxy. It doesn't revolves through Sun. But, it revolves through our another star, which is Betelgeuse.
Actually the revolve thing was just my guess, but anyway you can search for it.

Answer 9

that's a question that some men have been asking for a long time. And every time they say they have found life on another planet, it turns out to be a false alarm.

Not even a trace of an earthworm in outer space has been found.

The conditions on earth have been found to be unique.

Ask God.

Answer 10

Possibly not another Earth such as our Earth, but then again the possibilities are endless to the point of infinite.
It would seem extremely conceited of us to think that we are the only life forms in infinity.
