SUMMARY

The discussion centers on the evaporation of black holes, referencing Stephen Hawking's theory that black holes emit radiation and can eventually disappear. Participants clarify that while black holes absorb matter, smaller black holes evaporate faster due to their higher radiation rates. The conversation also touches on the density of black holes, explaining that as they lose mass, they become denser until they reach Planck mass, at which point they may release a significant amount of energy. The final moments of a black hole's evaporation could result in a substantial energy release, but not a supernova-like explosion.

PREREQUISITES
  • Understanding of Hawking radiation and black hole thermodynamics
  • Familiarity with the Schwarzschild formula and its implications
  • Knowledge of the four fundamental forces of physics: gravity, strong force, weak force, and electromagnetism
  • Basic concepts of quantum mechanics, particularly regarding singularities
NEXT STEPS
  • Research the implications of Hawking radiation on black hole lifespan
  • Study the Schwarzschild radius and its relationship to black hole density
  • Explore the concept of Planck mass and its significance in black hole evaporation
  • Investigate theories regarding primordial black holes and their potential evaporation
USEFUL FOR

Astronomers, physicists, and students of cosmology interested in black hole dynamics, particularly those exploring the intersection of quantum mechanics and general relativity.

What I said is that the impact that results in a neutron star "overcomes" might be a better word ("extinguishes") the weak nuclear force such that only the strong force and gravity remain. That is true, too.

No it's not. If you raise the temperature you can reach a point where the difference between the forces are not important, but if you just increase gravity that's not going to do it.

Think of it this way. If you take a chair and a cup of coffee and heat them to 10,000K, they basically behave more or less the same way. A 10,000K chair and a 10,000K cup of coffee are just going to be gases that tend to act in the same ways. The hotter you make the chair and the cup of coffee, the more similar they are going to be. At 10,000K, they still have different elements, but if you heat things to 10 million K, the chair and the cup of coffee are going to break down into protons and electrons and then they *really* start being similar.

All the talk about "force unification" is an extension to that idea.

But if you crush the chair and the cup of coffee and don't increase the temperature, they are still going to be very different.

You still have the weak nuclear force happening in a neutron star, and the weak nuclear force is *extremely* important in neutron stars since it provides the neutrinos that have something to do with blowing up the star.

If there are forces strong enough to snub out each of the 3 forces, given larger masses and more powerful implosions, why not speculate as to an event, that could also snub out gravity.

Because the *if* is as far as we know incorrect. Gravity doesn't "snub out" the other forces.

Since the above warning was not heeded, and speculation continued without evidence, it's time to close this thread.
