TIL: perhaps you have heard that black holes are something detected (Cygnus X-1) and well established, while white holes are a mathematical solution, but probably they don't exist.
But the theoretical physicist Carlo Rovelli thinks the opposite! He suggests that there're essentially no black holes in the universe, only stars collapsing more and more slowly due to time dilation. His proposal is that the singularity never forms because of the effects of quantum gravity and that these effects somehow spit out all the matter, creating a white hole.
I guess the community is very sceptical of all this, and rightly so. I wonder how Rovelli explains the detection of gravitational waves via black holes merging. (I'm not discussing his height as a physicist, though. I'm sure he has developed an explanation).
