Do you believe there is other intelligent life in distant galaxies? If no, why not? If yes, do you believe this is something to be feared and avoided or actively sought out?
I certainly suspect there is, but without some heavy-duty changes in our understanding of physics, I don't expect us to ever really know.
Heck, the chances of us stumbling on intelligent life in our OWN galaxy are pretty darn remote. Space is very, very big and very, very empty.
