Cosmologists create 4k virtual universes to solve Big Bang mystery

"Cosmologists are pressing rewind on the first instant after the Big Bang by simulating 4,000 versions of the universe on a massive supercomputer.

The goal is to paint a picture of the immediate aftermath of the Big Bang, when the observable universe suddenly expanded 1 trillion trillion times in size in the tiniest sliver of a microsecond. By applying the method used for the simulations to real observations of today's universe, researchers hope to arrive at an accurate understanding of what this inflationary period looked like.

'We are trying to do something like guessing a baby photo of our universe from the latest picture,' study leader Masato Shirasaki, a cosmologist at the National Astronomical Observatory of Japan (NAOJ), wrote in an email to Live Science."

Would be nice to have more details on how they constructed their models, and how they captured variance between each model seed. Otherwise this is just fluff, like "cool story bro".
