Simulation.

Most people would agree that the planet earth is pretty large.  Not huge and maybe small in comparison to the galaxy or the universe, but it is large when compared to the things you see and interact with on a daily bases.  And something else people would agree with is that we have some pretty impressive technology as well and we have the ability to simulate quiet large or complicated things.  I have two things to talk about, having to do with both of these things.  First, the popular game minecraft is a simulation of a land in which you can do a lot of a things, but not a lot of people know the full size of the game.  In truth it is quite large.  The game explored to its full size is about the same size as Neptune.  A planet that is larger then ours.  We as humans have made things that have the ability to simulate a world that is larger then our own.  That i think is quite insane.  But it gets better, a team in Austria made a simulation that was so large and in depth it took not 1, not 5 or 100 computers but 500+ computers.  It is a simulation of our Universe at its young age.  It looks amazing, and was well worth the 30 years of computing hours.  If you want to see the final product i highly suggest that you do, and you can download the video at there site.  Here is a link.  Its called the Millennium Run.  here is a photo of what it looks like.  Simply Awesome.
