If you ever wondered what the entire universe looks like, I can refer you to some stunning video illustrations, including this one.  One thing to keep in mind when viewing simulations like this is that your point-of-view zooms around at impossibly high speeds, far faster than anything even Star Trek writers dared to consider.  So allow some artistic license.

In 1911, Albert Einstein applied his theory of general relativity to calculate how gravity bends light rays.  One hundred years later — thanks to new satellite observations, extensions of his theories and computing power — we have a much better appreciation of our place in the cosmos.  Now, if we can only get this living-together-peacefully thing down, Einstein might think we accomplished something.
