Computer simulations of the Universe have recently been able to finally simulate the characteristics of real galaxies by tweaking the Galactic Wind.
I love computer simulations. They’re kinda like grandmas.
Generally speaking, if you can successfully explain something arcane to your grandma, then you probably have a decent understanding of the topic. Historically, this has not been the case with simulations of galaxies. Many different types of astronomical simulations have been successful and illuminating but galaxies themselves didn’t really match up to reality.They were either too small or too big. If not that, then they were probably too old or too perfectly spherical.
