Isn't it just mad that there's anything at all there to form these things depends on my state but that one gets to me. If u think about what we understand today 50 or 60 or even a 100 years ago it would have been completely mad to think it so in another 50 or 60 years what we think is mad today may be normal so I think we have a few i think im going to soil myself moments ahead of us when we realise.😂😂

Maybe it's electrons combining with protons?

Maybe when we observe galaxies from a distance appears that they are centrifugal. Maybe all the matter in a galaxy is literally falling down a hole?

Reality is far more complex and multilayered than any single system can fully describe. The fact that we have not encountered or studied certain models of reality does not mean they do not exist. There are dimensions, forms of consciousness, and modes of being that remain beyond our current perception and language.

"Just because you can't see it doesn't mean it's not there" as it is with air and black holes, also as it is with aliens, just because we can't see them doesn't mean they aren't there 😆

I don't miss Lawrence Kraus I get creeped out every time I see him and remember the SA allegations he was under years ago.

To Grow Big Galaxies, What if the initial assumptions are wrong? In other early universe scenarios, change the initial assumptions about the density of matter before first light. It's not smooth and uniform. It's more like a water puddle kids jump in. The singularity blew itself apart. Energy in the form of heat expanded rapidly. After a few million years some energy cooled into matter. Why would matter be smooth and evenly disbursed? How do atoms clump together to make small bits of matter with greater pull to drawn more bits. Clump clump clump bits fuse quickly in the first light universe. It's easy. As the clumps coalesce they leave voids where they came from. The bigger clumps fuse to make stars. The stars gather together to make galaxies. The stars grow until they've caught most of the matter around themselves, leaving little voids in their wake. Stars combine with nearby stars to create massive galaxies, leaving voids in their wake. The galaxies are HUGE, with massive stars that burn out fast, explode and spray metals into the gasses in the galaxies to make more stars, repeat repeat repeat. How could early galaxies be anything but massive, forming black holes in the center amid huge exploding stars. Some stars join the black hole, some stars are flung into the cosmos, outside the "shrinking" galaxy, where the form new smaller galaxies. Repeat repeat repeat etc.

Anytime anyone says nebulas or supernovae, I cringe! It’s nebulae and supernovae, respectively

I don't get it. Red dwarfs can live trillions of years. While other stars can't, so what does this even mean 😅😊
