100 Billion Galaxies

I know I haven’t written a substantive post on my site for a while.  I apologize for that.  I’ve been busy working in the lab and doing my own research on various things!  I do have plans to write a good post here soon.

Besides studying solid state physics, I’ve been researching international relations and political theory.  I’ll be writing up some posts on those things, I think.  In the meantime, I found a great video which goes along well with the photograph I posted just the other night.

“Those worlds in space are as countless as all the grains of sand on all the beaches of the Earth.  Each of those worlds is as real as ours, in every one of them there is a succession of incidents, events, occurrences which influence its future.  Countless worlds.  Numberless moments.  An immensity of space and time.”

– Carl Sagan

“There are in fact 100 billion galaxies, each of which contain something like a 100 billion stars. Think of how many stars, and planets, and kinds of life there may be in this vast and awesome universe.” “We find that we live on an insignificant planet, of a humdrum star, lost in a galaxy, tucked away in some forgotten corner of a universe, in which there are far more galaxies than people.”

– Carl Sagan
