This could be the first time you have heard about a white hole (WH). Meanwhile, we have been hearing for quite some time about “black holes” (BH) as regions in outer space where nothing — not even light — could escape. Such cosmological entities, roughly represented by a singularity or point of infinite energy/mass/information density and an event horizon defining the “size” of the BH, are increasingly subjects of study. In addition, the possibility of detecting gravitational signatures as the ones detected two years ago, coming allegedly from the collision and merging of two black holes, have increased their interest even more. So, what about WH?
The obscure regions of space called BH have, at least theoretically, a counterpart mathematical description, which would imply an opposite behavior; a region of space where nothing — not even light — could ever enter. For this reason, they are referred to as white holes (WH). Just as BH, WH started as a hypothetical mathematical situation with no equivalence in the physical realm, and just as BH, maybe WH do exist after all.
This is the theory Nassim Haramein has alluded to for decades. The same idea is being explored by different research teams, among them, Carlo Rovelli, a theoretical physicist at Aix-Marseille University in France, and his colleagues, who suggested that BH and WH might be connected. A BH could quantum-tunnel into a WH; once a BH evaporates to a degree where it could not shrink any further (assuming a quantized space-time), the disappearing or “dying” BH would rebound, forming a WH. This translates to matter collapsing into a BH and then emerging from a WH. As the authors Haggard and Rovelli claim “this scenario alters radically the discussion on the black hole information puzzle.” https://arxiv.org/pdf/1407.0989.pdf
But this is not all… WH could account for most of the mysterious dark matter in the universe, some of which may even predate the Big Bang!
So, probably, we will be hearing about these new and exotic entities increasingly more…
