starless sky

I heard a physicist talk about the universe expanding.  It was a pretty cool and a little bit geeky, but still accessible to me.  It was fascinating.  I read more about the work that is the basis for the talk.  A couple guys won a nobel prize a couple years ago for showing that universe is not only getting bigger, but that things the universe is accelerating away from itself.

The force moving stars apart is stronger than the gravity holding them close.  This means that eventually that stars will be moving away from us so fast that they will be going the speed of light (or faster even?).  If stars in the sky are going away from us at the speed of light then their light will never reach us.  The sky will eventually just be dark!  This might not be news, but I read it with gravitas.

It's pretty amazing to be here NOW.  There are countless cliches about living right now and in the moment.  They're sometimes inspirational and often overused and ineffective.  I read about this discovery and found it pretty inspirational.  One day the world will be different.  One day we actually won't be able to see stars in the sky.  I'm glad that's not today.  Things are pretty good today.
