Now since Daecon has specifically raised this issue and wants to know why this nuclear force thingie is poposcience, then I must clarify...before you proceed you may like to brush up by referring
https://en.wikipedia.org/wiki/Strong_interaction
1. In the context, your reference is about Strong Nuclear Force as attractive force between Neutron/Proton in a nucleus which is very strong. This force binds the nucleons together by despite the Proton-Proton repulsion. The classic theory behind this with potential well is know to any middle school Physics student, but it has something more which if required/raised will be taken up later.
2. This attraction force is inward, and Gravitational collapse is also inward, so there is no need for Gravity to overcome this. Gravity will have to overcome if this attraction force acts as resistance to collapse but it does not. So his argument fails here itself.
3. When a core collapses and say it has sufficient mass to form just the Neutron Star, then all Neutrons in the inner core, has strong Nuclear Force binding them, Gravity also acts as compressive / binding force only, so in the Neutron Star there is no overcoming of Nuclear Force (Which is present in its extreme maxima) by Gravity.
4. If the star core mass is more, then the 'Equation of state of matter' changes, and we really do not know, what becomes of Neutrons, you may like to read about hypothetical Quark Stars, and also above wiki link would have given you an idea about strong interaction...but thats no longer Nuclear Force, as there are no longer Neutrons/Protons...so called some kind of hypothesized Quarks/Gluons soup.
5. if the star core mass is still more than, a BH comes, and we know nothing about Equation of State for sure beyond Neutron Star, not even mathematically.
So can anyone pin point where the Gravity has overcome the strong Nuclear Force and how ?
Now coming to mass accretion by Black Hole..
6. If the BH is large, then nothing untoward may happen near EH because tidal forces may not be so strong. As the object approaches singularity, tidal forces become significant. How these Tidal Forces overcome Strong Nuclear Force, I do not know, this is a free fall and we do not know the maths under such extreme Gravity. The plight of the object as it merges with the singulairty (or vanishes to oblivion) is unknown...Its a very complex stuff and I am not aware of any paper/work which talks of a condition when for pair of Neutrons or protons or for Neutron Proton pair (Tidal Force > Strong Nuclear Force).
If any of you can put a paper, which explicitly discusses this issue, I am willing to retract.
So, I urge all three of you, pl desist from making such false accusations that I am terming mainstream as poposcience. I have no problem with your blind support to Paddoboy's popscience, Poposcience and adhoms posts, but do not make false representations. Post some science, contribute, not some one liners.
