Video Clip: The Fermi Paradox

This video on the Fermi Paradox by Kurz Gesagt is a thought-provoking piece on the absence of other known civilizations in our galaxy.  He also talks about the impossibility of travel to any other galaxies outside our cluster due to increasing distances. It is a very sobering piece, though I think we have plenty to explore in our own neighborhood, particularly if the space is available for settlement.  

Unless, as he postulates, a Type III civilization that controls the entire Milky Way is zapping potential civilizations that rise to threaten the neighborhood.  Think of it as the opposite of Star Trek where the Vulcans step in and help an emerging Earth.  This bleak scenario is close to ideas expressed by Dr. Hawking, where he noted we could get into trouble as we become a space-faring civilization.  Plenty to ponder as we move forward with SETI and space travel.

Mr. Gesagt has other informative video, including videos on the big bang and our moon.  I recommend you take a look at these videos as well.
