Re: Life on Other Planets?
I think it's possible that there's life on other planets. But first we have to find them.
As for "visits," I'm a doubter. So far as we know, the speed of light is the absolute upper limit for velocity in the universe. It would take a LONG TIME to get from "there" to here. The nearest star is over 26,000,000,000,000 miles away (4.2 light years).
One of my friends is an astronomy geek. He is of the opinion that intelligent life would probably blow itself to smithereens before it could get to the point of sending an investigative probe to other stars.
