In this video, a supercomputing simulation depicts the physics involved in the formation of the Milky Way. Researchers at the University of California, Santa Cruz and the Institute for Theoretical Physics in Zurich used over 8 months of supercomputing time to run the simulation, called “Eris,” which solves a long-standing problem that led some to question the prevailing cosmological model of our universe.o complete their analysis.

Previous efforts to form a massive disk galaxy like the Milky Way had failed, because the simulated galaxies ended up with huge central bulges compared to the size of the disk,” said Javiera Guedes, the postdoctoral researcher at ETH Zurich who authored the study.
