Did our cosmos begin inside a black hole in another universe? New study questions Big Bang theory
"Challenging long-held assumptions is essential to scientific progress."
makes sense to me considering Webb is finding 'old' galaxies in early universe.
This is a Big Bounce theory, so it will not help explain "old" galaxies. It still presupposes the observable universe went through a short period of extreme density and temperature, just not one infinitely dense. Galaxies and stars would not have survived. The article does say the theory allows for existence of pre-primordial black holes though, which is cool. That also allows for the possibility that primordial supermassive black holes "seeded" the early galaxies, enabling them to develop faster than existing models predict. We are still not exactly sure whether galaxies develop around SBHs, or whether SBHs grow in the centers of galaxies.
@m3t00 that would make sense, as matter collapses into singularity anyway. It should be reversible
singularity is a math view. sort of like 'dark' matter. so called because math says it's there. unseen. i'm guessing a more dense state of matter. i'm no physicist. just a guess.
@m3t00 i was also thinking about maybe singularity is a small big bangs.
If black holes actually may explode, then the white hole and big bang are the same thing. If that is true, then big bang happened after the death of big black hole.
