If you haven't seen it yet, the simulation released last year of the hypothesized Earth-Theia moon formation is really cool: [VIDEO]

It's not my area, but this video looks interesting and is produced by NASA " New Supercomputer Simulation Sheds Light on Moon’s Origin " (October 2022) [VIDEO]

What I want to see is the Theia collision rendered in realistic 3D (and if there was enough gas around for sound to carry, that too!) [LINK] I guess this is close but not like the Hollywood blockbuster it should be [VIDEO] [LINK]
