Alienation

Do extraterrestrials exist?

It's difficult to conceive of no other life forms in a universe consisting of 100 billion galaxies. It's equally inconceivable to me how interstellar travel is possible. With the innumerable options available it seems a tad unlikely for aliens to be attracted to a planet extremely polluted by its inhabitants for global domination at extreme warfare cost. It makes for great movies, though (discounting Battlefield Earth, of course).

Agreed completely, except that we might "meet" them in the form of microbes or tardigrades or other life that we might not even recognize as life because it's beyond our normal perception. We might have already "met" life in that form, with everything that drifts into our solar system.

I came upon an article asking astronomers what they thought and I thought it was a neat idea.

I'd like to think there's a network of intelligent life out there. As the famous poster says, "I want to believe."

Maybe interstellar transit isn't impossible after all. I have no idea how feasible that technology is, but it's an interesting idea.
