White holes are mathematically possible, according to general relativity. But does that mean they're actually out there?

Also Idk what you are talking about nobody believing there's an actual singularity; I don't know what else you think is happening, or of what use the mathematics might be if it doesn't approach some degree of accuracy as concerns the physical character of the phenomena

Here's some reading about black holes singularities and whether they're real or not:

https://en.wikipedia.org/wiki/Gravitational_singularity#Interpretation

We know that GR predicts some things extremely well, and QM some things extremely well, but they fundamentally disagree. Both CANNOT be entirely correct, and black holes is the most notable case where one or both break down. (See the "black hole information paradox".)
