Watch this stunning Starforge simulation of a star being born

Catastrophe

"There never was a good war, or a bad peace."
"Researchers hope that the visually stunning simulation will help them to explore the many unsolved mysteries of star formation, such as: Why is the process so slow and inefficient? What determines a star’s mass? And why do stars tend to cluster together?"


"Stars can take tens of millions of years to form — growing from billowing clouds of turbulent dust and gas to gently glowing protostars, before materializing into gigantic orbs of fusion-powered plasma like our sun. While studying the night sky enables astrophysicists to glimpse brief snapshots of a star’s evolution, they need to use an accurate simulation to view and study the full process."


"If we can understand star formation, then we can understand galaxy formation. And by understanding galaxy formation, we can understand more about what the universe is made of," Grudić said. "Understanding where we come from and how we're situated in the universe ultimately hinges on understanding the origins of stars."

Well worth a look.

I watched the video and the time counter stops about 4.3 million years into the simulation. Star formation theories are tricky. Here is a report demonstrating this using higher mass stars. High-mass stars are formed not from dust disk but from debris, https://phys.org/news/2021-05-high-mass-stars-disk-debris.html, May-2021. "A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic mess..."

My observation. In the BB model, the CMBR forms at or near 1.198 x 10^13 seconds after BB. The universe today is about 4.35 x 10^17 seconds after the BB. Thus, between 10^13 seconds after the BB and 10^17 seconds after BB for the present, the universe must undergo an enormous evolutionary transformation to explain all that we do observe today using telescopes, not including all that is not observable in the BB model, e.g. Population III stars or original, primordial gas clouds.
