One thing worth looking into is the "Fermi Paradox". It concerns not only the possibility of intelligent life and communication but interstellar travel. If interstellar travel were possible in even thousands of years and the development of intelligent life capable of achieving it were possible in the current age of the universe then we should've seen signs of it flooding the galaxy by now. We haven't seen a single peep.

I'll let you know after my round trip to Proxima Centauri :D

I know about the Fermi Paradox! The resolution of it that makes most sense to me is the Great Filter idea. Looking at our own civilization... Yeah. That checks out.
