The 2011 Nobel Prize in Physics
“Some say the world will end in fire, some say in ice…” *
What will be the final destiny of the Universe? Probably it will end in ice, if we are to believe this year’s Nobel Laureates in Physics. They have studied several dozen exploding stars, called supernovae, and discovered that the Universe is expanding at an ever-accelerating rate. The discovery came as a complete surprise even to the Laureates themselves.

It should be noted that this is a simulation of one possible way our universe might evolve, one that current observations suggest is incorrect. However, it is a solution of Einstein’s equations of General Relativity, and as such well worth studying.
When I was much younger something like this might have been called an “analog computer.” I have not seen that term much lately.
