Simulations of the Dark Matter
The way we do the simulations is quite simple. We have these initial conditions starting state which we represent mathematically and feed that into a big computer. Secondly we make an assumption about what the dark matter consists of. Thirdly we instruct the computer on how to solve the equations of physics, Einstein's relativity and so on. And fourthly we let it compute often for months in a rowbig computers can do this. What comes out at the end are universes when you make the right assumptions about the dark matter that look just like the universe in which we live. So long as we make the correct hypotheses for the nature of the dark matter.
