Do you think there are planets similar to earth in different galaxies?

Question

Do you think we could ever get to them?

Answer 1

There are some scientists who believe that planets like Earth are extremely rare, and that ours might be the only such planet in the whole galaxy. I also know that many other scientists do not accept this argument. With some 400 billion stars, I think that there's a good chance of finding lots of other Earths out there, even if they are "rare" compared to uninhabitable worlds.

In terms of other galaxies, I'd say it's a dead cert that every large galaxy (at least every spiral) has at least one Earth-like planet with life. I'm not so sure about elliptical galaxies.

Answer 2

Not only in different galaxies but in our own galaxy.

Answer 3

its a possibility

even if there aren't many like earth, i'm sure most of them contain life

and, guess what

if there is a planet out there with the same conditions as earth(same geographical properties, same type of star, etc.), the planet can have life similar to us

Answer 4

there are possibilities that there are planets like earth somewhere in space.

Answer 5

It seems very unlikely that Earth is the only planet capable of sustaining life.

There are probably thousands or even millions of such planets in the Milky Way galaxy alone, which has some 400 billion stars.

Answer 6

Given how vast the universe is and even our Milky Way galaxy I'd say it is close to certain.

Answer 7

Of course, the fact that ours is here, and the sheer size of the universe, the number of stars, galaxies, etc, its just utterly impossible that there isn't. But getting to them? I highly doubt it. Again look at the distances of space, even traveling at the speed of light it would take us millions of years to even reach our neighbouring galaxies.

Answer 8

Gliese 581c is planet not too far from us that resembles the Earth and it was discovered last year!

Answer 9

we have a lot in our own galaxy... they are farr...but we will be able 2 reach them some day

and if u wanted 2 know if life is present in other galxies... well. it IS!!
