When the black hole was first proposed as a vacuum solution to Einstein's equations of general relativity, it was received with great skepticism to the possibility of it representing an actual astronomical object. At the time, gravity was understood only in the context of mass, and such strong gravitational field could only be created by a highly compact mass. Our deeper understanding of quantum entanglement nowadays, allows in our opinion for a reinterpretation of black holes. Specifically, we suggest that the strong gravitational field at the center of the black hole could actually be due to the vacuum as originally suggested. The black hole could be understood as consisting of different degrees of energy from grosser at the periphery to subtler at the center, the origin of which could be the fact that all energy tends to decay towards the ground state of the vacuum, a state of perfect cancellation between matter-antimatter. The higher the rate of arising and disintegration of matter-antimatter pairs, the stronger the gravitational field.
Dear Gemma F. Lopez , I agree with your hypothesis but I would omit "at the center": the strong gravitational field of a black hole is due to the quantum vacuum space inside the photon sphere. The second part of your assumption is, in my opinion, inexact because there isn't any gradient of energy inside. Regards!
Jacinto Jesús Rodríguez Pérez how (by which mechanism) is the quantum vacuum the cause of the strong gravitational field inside the photon sphere?
Appreciated Gemma F. Lopez , there are two approaches to understanding the physics of the black holes: the traditional one is mathematical (metric, curvature, ...) but there is another one that emphasizes how a black hole forms. If we admit that black holes are a consequence of the stellar death in the form of a supernova, the quantum vacuum (a region where the metric is not defined) is produced by that extreme explosion . With this in mind, you can establish a bridge between General Relativity (the mathematical model) and reality. I can't be more specific (if you check the second tweet of this Twitter account: @jjrodrip you will be able to understand my reasons)
Jacinto Jesús Rodríguez Pérez One of the problems of conceiving black holes as formed only as a consequence of stellar death, is that it is difficult (or simply not possible) to explain the origin of supermassive black holes formed at very early stages of the Universe.
Another mechanism is therefore needed to explain black hole formation which is more compatible with our observations towards early stages of the Universe.
Estimated Gemma F. Lopez , your objection is correct (from the point of view of our present understanding) but... suppose that you don't need an intense convergence of pre-galactic gas or matter in order to form a supermassive black hole and that the only requisite is a vacuum region (as you proposed in the statement of your question and like those present In the infancy of the Universe). My turn of question: How do you ascribe mass to an empty region of space (or vacuum region)?
We can't ascribe mass to an empty region of space so the mass of a Black Hole is zero. This fact is in concordance with "a vacuum solution to Einstein's equations of General Relativity" ( Gemma F. Lopez ). But this result arise another question: How can we explain its gravitational field?
1.- The space sorrounded the singularity inherit the angular momentum of the progenitor star before the supernova explosion ( Sydney Ernest Grimm
wrote: "vacuum space around" is responsible for the creation of gravity)2.- The temperature of the region fall "very rapidly" (So we have heat transfer with the rest of surrounding Universe in form of Electromagnetic Waves)
and 3.- We must use the results of the experiments carry on by Louis Rancourt and Philip J. Tattersall:"Further Experiments the Effect of Light on Gravitation" and mentioned by Sydney Ernest Grimm
.With these three points in mind we can understand why the bodies have weight and fall in a vacuum region.
