Solomonoff's razor says there's nothing suspicious about the universe being big, so he must be very wise and I believe everything he says (pending further evidence).
It's 5am in the morning where i am, i inputed the figure into chatgpt pro for an explanation. No idea whether anything of it is correct. But i seriously enjoyed the trip.
Yes, the radius is somehow linear in the mass, instead of the 1/3 power of mass like it would be for constant density. I stopped my physics journey at special relativity so I can't explain why. https://en.m.wikipedia.org/wiki/Schwarzschild_radius
One thing to note is that if the universe's mass is uniform outside the hubble volume, it wouldn't be a black hole, because that expression assumes a vacuum outside the volume, with no gravity counteracting the forces pulling in, but still an extremely odd coincidence if in fact it is.
seems really small and flat to me. you could binary search it left to right and find a particular atom in a few minutes. largest and smallest scales differ by only 200 doublings, with us in the middle. that's the 200th lowest number in existence, out of infinity

"We explain how this depends on the unlikely assumption that our Universe is surrounded by zero density Minkowski space."
