Related: About this forumBlack holes: Not endings, but beginnings? Theoretical study delves into 'white holes'
https://phys.org/news/2025-03-black-holes-theoretical-delves-white.htmlOur understanding of black holes, time and the mysterious dark energy that dominates the universe could be revolutionized, as new University of Sheffield research helps unravel the mysteries of the cosmos.
. . .
Using the laws of quantum mechanics, a fundamental theory describing the nature of the universe at the level of atoms and even smaller particles, the new study proposes a radically different theoretical standpoint where, rather than a singularity signifying the end, it could represent a new beginning.
The new paper, titled "Black Hole Singularity Resolution in Unimodular Gravity from Unitarity," published today in Physical Review Letters, aims to illustrate the point where our current grasp of physics and time falters.
While black holes are often described as sucking everything, including time, into a point of nothingness, in the paper, white holes are theorized to act in reverse, ejecting matter, energy and time back into the universe.

Interesting... The referenced paper is a bit beyond my comprehension but I'll work on it.

Maybe white holes are actually dark holes. Perhaps ordinary matter gets sucked into black holes, converted into dark matter and dark energy and spewed out in the neighbourhood or some distant place.
