Will we ever live on other planets?

Question

Scientific answers only please

Answer 1

If we can avoid destroying the Earth through global warming or nuclear war, then yes, we will someday inhabit other planets. I would say we are at least 100 years away though, due to the extraordinary expense of developing the required technologies.

Answer 2

We could colonize Mars now if we were to follow Robert Zubrin's suggestions.

We will have colonists on the moon in 20 years, rotating through much like the scientists do in Antarctica.

In the near future, we will colonize and terraform Mars first. It will be comparatively easy, there will be billions of colonists living there in 200 years. Then we will terraform Venus and Callisto next, and they will be difficult.

We either colonize other planets or go extinct.

And I think that for all we know, intelligence such as ours may be very rare and precious in our corner of the cosmos and it would be a shame to squander it.

Answer 3

I think it's inevitable that humans will have at least some kind of colony effort on Mars ... but ONLY Mars, for the foreseeable future. Any other planet would be too difficult or unsuitable, and other star systems too far away.

Answer 4

I doubt "we" (living now) ever will, but it's a good bet that our descendants will someday terraform Mars and build cities there.

Answer 5

Not until they can support human life. Otherwise, way too expensive and dangerous.

Answer 6

That's like asking will we ever invent a time machine...
Who Freakin' knows?!?
