Can we simulate the Universe?
Summary
Daniel and Kelly explore how scientists use computer simulations to study cosmic evolution, focusing on the FLAMINGO project. This massive simulation incorporates complex physics like hydrodynamics and neutrinos to model galaxy formation more accurately than previous models. The hosts discuss why these approximations are necessary, how they help test theories about dark matter, and whether our universe itself could be a simulation.
