What should I program?

Ok, /prog/. A wizard gave me a One Quadrillion Trillion Quadrillion 65536-bit Floating Point Operations Per Second computer to use, with 2²³² terabytes of memory, two T1 lines, and it works off of a gram of sugar per day.

What should my first project be on this new computer? I want to make something a little more interesting than fibs.

Create a computer simulation of the Universe incorporating every relevant equation know to man, including QM and your choice of theory (I suggest M theory).
