Here’s a fascinating physics model by computer artist Mark J. Stock, showing the 3-dimensional movements of 1 million bodies, each given their own gravity:

One can easily imagine witnessing the birth of galaxies after the Big Bang, millions — even billions — of years passing before your eyes in seconds! It’s amazing how quickly a large “web” structure forms, very much like the structure of galactic superclusters and filaments that are observed to exist in our Universe today.
Mark J. Stock is a talented artist specializing in “computational artwork”. Check out his website here, and see more videos on his YouTube channel.

Amazing! But what happens into the future with this model? Do all the bodies collapse together in a giant black hole like physicists predict?

I don’t know. The simulation ends before the Big Crunch…
