Markus Hanke Posted December 6, 2022 Posted December 6, 2022 https://www.quantamagazine.org/asymmetry-detected-in-the-distribution-of-galaxies-20221205/ https://arxiv.org/abs/2206.03625 Now this is very interesting! Despite the 7-sigma significance mentioned in the paper, this will of course require further corroboration. But if this turns out to be a real thing, then it would have far-reaching consequences. Definitely one to watch!
MigL Posted December 6, 2022 Posted December 6, 2022 At first I thought this was a violation of isotropy and homogeneity, indicating the universe has a 'drection', but on reading the link, I realized it is another ( of a few ) parity violations. Who knows, investigatng the cause of this effect at the earliest moments of the Big Bang, may shed some light on why the current universe is predomiinantly matter, and almost devoid of anti-matter. ( but I doubt it )
Mordred Posted December 6, 2022 Posted December 6, 2022 Interesting read will have to study it later. Thanks for sharing
joigus Posted December 7, 2022 Posted December 7, 2022 Very interesting. Thank you.

Yes, it took me some time to picture it in my mind. It's not the most intuitive picture I can think of. A mirror asymmetry that's compatible with spatial isotropy and homogeneity is certainly possible. Every bit of tetrahedral clustering slightly skewed on the average.
