Etchings on the Attic Wall

Here’s an interesting animation.  It goes through a slide show describing what will happen to Earth over the course of 7.1 billion years.  You can see how the continents, climate, and solar system will change.  Boggles the mind, doesn’t it?  Humans had better be relocated by about 3.5 billion years because Earth won’t be hospitable for life anymore.  Yes, this is a LONG ways away, but is a very compelling reason why we should continue to invest in space flight and exploration.  We likely won’t last another thousand years if we continue to destroy the environment like we are doing.
