The quantum mechanics of The Quantum Universe provides a concrete model of nature that is comparable in its essence to Newton’s laws of motion, Maxwell’s theory of electricity and magnetism, and Einstein’s theory of relativity.
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Anything that enters a Black hole is lost from the observational Universe. In a matter of speaking, one might think that it is destroyed. But how can it be destroyed?
The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain constant—it can neither increase nor decrease without interference from outside.
Today, we’ll consider Black Holes to be a part of a closed 11 dimensional Universe according to the String Theory.
If that is so, Black Holes cannot lead to destruction of any energy. Not even a single particle. It should rather just be changed from one form to another, or moved from one dimension to another.
Black Holes are huge areas in Spacetime with extreme Gravity.
You are using a vacuum cleaner. In front of you, there is a chunk of sand held together by low quantities of moisture. When it will be sucked in, that chunk of sand will break down into thousands of grains of sand. That would be a result of pressure and evaporation of moisture. But the entire mass that existed outside the vacuum cleaner will still exist inside it, just in a different form.
Now, applying the same observation and analysis to a Black Hole and considering the fact that no energy can be destroyed inside a closed 11 dimensional Universe, one might stumble upon the possibility of existence of sub-atomic Universe inside a Black Hole.
All matter and energy is stretched and transformed into sub-atomic particles inside a Black Hole. We know that no light can escape a Black Hole but that doesn’t mean a Black Hole is dark on the inside.
Black Hole may not let light escape, but it cannot even destroy it.
For example, if you have a vantablack jar and you light a bulb inside it, no light would escape the boundary of jar but there would still be some light inside the jar.
If all of this happens inside a Black Hole, it may very well be possible that Black Holes are the Quantum Universes.
