If we’re ignoring the fact that it would probably collapse into a black hole, and assuming that the entire universe is a sphere, and assuming that the inflationary theory estimate (the estimation that the entire universe is 10^23 times the size of the observable universe) is correct. How many hydrogen atoms packed completely together would fit into that unimaginable amount of space?

Also bonus, what is the number of all possible combinations of atom positions in that space down to the planck length/volume? Would that number be the factorial of the answer to the first question? What would it be
