Single naked black holes in my area?
I do research on dark matter, and one of the more interesting possibilities I have heard is that these black holes could in theory be formed by directly collapsing dark matter!
There’s and increasing amount of attention being spent investigating a slight modification to the standard Lambda cold dark matter cosmology, by allowing dark matter to have a little bit of self-interactions. These can then allow part of a larger dark matter halo to directly collapse into a black hole.
Oh yeah, baby, take it all off!
The ASSUMPTION of the uniformity of the early universe has always been exactly that: an ASSUMPTION. Anyone with half a fucking brain should’ve easily realized direct-collapse black holes should be expected in the Big Bang theory.
Anyone with a full brain knows that putting scientific phrasing into layman’s conversation conveys a much dumber message than is intended. “scientists assume…” yes because without making assumptions, they’ll never calculate anything. Assumptions get tweaked as evidence is presented. “Scientists can’t explain why…” scientists do not have a foolproof explanation. They have theories that are likely and make sense, bit nobody knows for absolutely certain that it’s true and extremely accurate. “Historians don’t know what happened…” because they weren’t there, but they probably have some good ideas.
I said what I said because I’ve heard far, FAR too many “scientists” use the assumption to dismiss blatant evidence against it. The constant pekachu facing at JWST pictures is frustrating beyond belief, and the dismissal of ideas before JWST provided evidence for those ideas has been tentamount to scientific dogma.
My original post is just pointing out that the dogma is, in fact, dogma.
Could there be a cycle of big bangs to big crunches, with a critical mass for a black hole causing it to explode/bang? During crunch phase localized black holes would form and possibly consolidate, and then instead of big bang being the entire mass of the universe, it can be most of the mass in the universe?
I think OP is saying this is very old because there is no mass around it for it to “feed” anymore. It would seem more probable for it to predate big bang rather than form soon after it.
