468: Simulations for Science and Fun Astronomy Cast 468: Simulations for Science and Fun by Fraser Cain & Dr. Pamela Gay

Astronomers depend on simulations to study the Universe. From relatively straightforward orbital simulations to vast simulations that try to recreate the large scale structure of the Universe from the Big Bang. Today we're going to talk about some of those simulations, as well as tools you can use simulate the Universe.
