Can a Multiverse Reverse Entropy and Lead to White Holes?

[hurk4]

In our observable universe it is observed that entropy develops from low to high. At the same time specialness goes from high to low. (see Penrose's road to reality). Apparently it is possible if we consider our observable universe as part of a black hole that black holes have no constant entropy. Maybe our universe develops from a white hole to a black hole with one or many singularities. Is it thinkable that in a multiverse a concentratation of radiation can occur reversing entropy from high to low leading to white holes (bigbang's) ?

It is possible that in a multiverse, concentrations of radiation could lead to the formation of white holes, or big bangs, which would reverse entropy from high to low. However, it is not clear how this could happen in practice, as the existing laws of physics do not allow for the conversion of energy into matter and vice versa. Additionally, some theoretical physicists have speculated that the universe is actually a part of a larger black hole, so it is not clear if the concept of a multiverse could be applied in this case.
