“If you use all the physics we know now, and you do this straightforward calculation – it’s bad news.

“What happens is you get just a quantum fluctuation that makes a tiny bubble of the vacuum the Universe really wants to be in. And because it’s a lower-energy state, this bubble will then expand, basically at the speed of light, and sweep everything before it,” the Fermi National Accelerator Laboratory theoretician told BBC News.”

In other words, this Universe will come to an end someday.  The implication of that is that life as we understand it, no matter where, no matter what form, will come to an end.  All life.  No matter how many solar systems are terraformed, no matter how many galaxies have spawned versions of ourselves, it will all end and there will be no life anywhere we would be able to observe were we around.  There will be no complex structures which rely upon water and fight an uphill battle against entropy.

So what does all this mean, if it will all go away?  Or at least be reduced to elemental levels and exposed to very harsh conditions?  Eliminated.  Oh, I know we as a species gets along as well as we can for as long as we can, and if we are going to disappear doesn’t that say something about  our importance and the importance of our endeavors?
