What Sonic Black Holes Can Teach Us About the Information Paradox
Do ‘dumbholes’ on Earth hold the key to a black hole’s interior?

I can relate to this article! The terms and images are associated with the “recovery” phase I just experienced. It was an “event.”
Excerpts:
Hawking’s theory suggested that black holes could behave as thermal, heat-emitting objects — in contradiction to the normal understanding of black holes as objects which never let energy escape. In 1974, Hawking proposed a solution to this contradiction by showing that, over exceptionally long timescales, black holes could have both entropy and emit radiation by taking into account their quantum effects. This phenomenon was dubbed “Hawking radiation”.
Hawking argued that black holes were actually acting as an idealized black body in space that absorbed all wavelengths of light, but which emitted energy called black body radiation, or Hawking radiation, all along the event horizon.
That is because of virtual particles — matter and anti-matter particles that momentarily spawn in space out of nothing and due to their proximity to each other — immediately annihilate each other and release the energy used to produce them in the first place. This maintains the vital law of thermodynamics that states that the energy of a closed system (the universe) must remain constant.
But, if a pair of virtual particles spawn along the edge of an event horizon, one of the two particles will get sucked into the black hole, while the remaining particle survives and flies away into space as a form of energy known as Hawking radiation.
You can see the problem, right? The universe just took some of its energy and created matter out of nothing, but didn’t get that energy back.
The only way Hawking radiation could be allowed to exist mathematically is if the in-falling particle actually had negative energy equal in magnitude to the positive energy used to create the two particles, thereby preserving the universe’s total energy.
And there’s more to read (if linear) and digest (if non-linear). It digested me !! There’s that Wiccan angle again !
