All mathematics is produced by physical objects (brains, computers). Therefore the laws of physics determine what theorems are possible, and mathematics has no existence independent of our universe.

You may have it almost exactly backwards. Math exists independently outside of our universe (and there may be perhaps > ~Tree (3) such universes in the multiverse). There are mathematical structures which are perfectly valid but are physically impossible to exist in our universe.

Well, no. Our physical brain and our mind/consciousness are two different entities. They may well exist in 2 (or more) different Universes. We are all made of the same particles - but the arrangements (their mathematical structures) matter. They don’t have to reside together.

The point is even if maths did not exist in our mind, i.e if there were no humans. Mathematical concepts would still exist in the universe.

They don't exist in our minds. Their understanding exists in our minds, not the structures themselves.
