Title: A theory about Black Holes: They may not have a singularity.
Post by: Diogo_Afonso_Leitao on 17/12/2015 14:32:51
Hello everyone! My name is Diogo and I am a 13 years old brazilian, so sorry for grammar errors (English is not my native language). Yesterday i had an idea about black holes and why they might not have a singularity in their center. This theory is most likely wrong since I am not a physicist (yet :D) so I am open to suggestions and critics

First of all, we need to think of black holes of another way. Black Holes are basically a region of space dense and massive enough so that it's escape velocity > c. Black holes are a result of a star collapsing. Let's see how this works:
1. Force of gravity constantly trying to make the star denser and denser
2. Nuclear fusion counteracts the force of gravity, making the star stable
3. The nuclear fusion of Iron (In the end of the life of supermassive stars) consumes more energy than releases. Therefore, nuclear fusion can no longer counteract the force of gravity. As a result, the star collapses into a black hole.

Theoretically, a singularity would form, since there is no way the collapsing star can counteract gravity. Here's my idea: Althought nuclear fusion of iron consumes more energy than releases, nuclear FISSION should be able to counteract gravity, therefore not creating a singularity.
Singularities are a quantum mechanics paradox and scientists are trying to create a new theory that unifies quantum mechanics and relativity to avoid the formation of singularities.

I thought it may be simpler: As an object gets really dense (close to singularity), it's temperature, density and pressure becomes so high that the collision of two atoms (Iron atoms) cause them to break up, releasing energy by nuclear fission.

However, this needs an exorbitant amount of pressure, which may occur only after the density is so big that it's escape velocity > c (It might only occur inside black holes).
So what I am proposing is that, inside black holes, there are extremely small stars (meters, centimeters or smaller of diameter), dense enough to create nuclear fission, counteracting gravity (not forming a singularity) and stabilizing a black hole. As the star gets denser, the rate in which nuclear fission occurs increases, which makes singularities impossible to happent.

What do you think of this idea? Is it plausible?
Thank you very much for reading!

Diogo_Afonso_Leitao, good on you for having a go young man. It's fantastic that your thinking about these things at 13.
I have a question.
Why do you think that Matter in a Black Hole exists as elements?
The reason I ask is, there is an established path from Elemental Matter, to a Black Hole.
For there to be Elements, that is Protons and Electrons, the most compact Mass is a White Dwarf with a Mass less than 1.4 Solar.
If it gets to 1.4 Solar electrons can no longer maintain the space/separation they need from the Nucleus. They recombine with the Protons and we have a Mass made entirely of Neutrons.

No more Elements, just Neutrons.

From there any further collapse leaves us looking at an Event Horizon. What lies within I don't think is anything that can Fission.
Unless maybe Quarks are not fundamental and can break down into even smaller units.
