Traditionally, astronomers have used this approach to invent and test new theories of <a href=\"https:\/\/phys.org\/tags\/galaxy+formation\/\" rel=\"tag\" class=\"\">galaxy formation<\/a>, one-by-one. Peter Behroozi, an assistant professor at the UA Steward Observatory, and his team overcame this hurdle by generating millions of different universes on a supercomputer, each of which obeyed different physical theories for how galaxies should form.<\/p>\n<p>The findings, published in the <i>Monthly Notices of the Royal Astronomical Society<\/i>, challenge fundamental ideas about the role dark matter plays in galaxy formation, how galaxies evolve over time and how they give birth to <a href=\"https:\/\/phys.org\/tags\/stars\/\" rel=\"tag\" class=\"\">stars<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How do galaxies such as our Milky Way come into existence?
