Saturday Science: The History of the Universe

From the description at YouTube:

Scientists at MIT have traced 13 billion years of galaxy evolution, from shortly after the Big Bang to the present day. Their simulation, named Illustris, captures both the massive scale of the Universe and the intriguing variety of galaxies -- something previous modelers have struggled to do. It produces a Universe that looks remarkably similar to what we see through our telescopes, giving us greater confidence in our understanding of the Universe, from the laws of physics to our theories about galaxy formation.

This is what it's describing:


It's fascinating, but the video moves a little too fast for me to follow very well. If you want more information, the research paper itself is here; it's behind a paywall, but you can read the Nature article about the project here. And via Towleroad, here's a rather more accessible discussion of the creation of the model at The Guardian.

It's like I've always said: The universe is a fascinating place.
