SUMMARY

The discussion centers on the concept of infinite density within black holes, specifically addressing the singularity at their core. It is established that infinite density is a mathematical abstraction rather than a physical reality, indicating a breakdown in current models. The standard model of black holes posits a singularity with zero volume containing all mass, but this leads to unresolved questions about the nature of matter under extreme gravitational pressure. Future advancements in quantum gravity theories are anticipated to provide clearer insights into black hole singularities.

PREREQUISITES
  • Understanding of black hole physics and general relativity
  • Familiarity with the concept of singularities in astrophysics
  • Basic knowledge of quantum gravity theories
  • Awareness of mathematical modeling in physics
NEXT STEPS
  • Research the implications of singularities in general relativity
  • Explore quantum gravity theories, such as string theory or loop quantum gravity
  • Study the mathematical models that lead to the concept of infinite density
  • Investigate current research on black hole information paradox and its implications
USEFUL FOR

Astronomers, physicists, and students of theoretical physics who are interested in the nature of black holes and the fundamental laws governing the universe.

If an object is infinitely dense, does this simply mean that there is no empty space within the object? I'm hung up on the fact that you can't possibly get denser than infinite density; what is stopping a black hole from getting even denser? What happens to atoms once they're under such intense gravitational pressure? !

It is not believed that "infinite density" exists in the real world. It is a mathematical fiction that is the result of some model's calculations and is therefore taken as a sign that the model breaks down at the point where it gives infinity as a result.

For example, the most standard model of a black hole says there is a singularity at the center that has zero volume and all of the mass of the black hole and therefore infinite density, but what that really means is that we don't understand the black hole singularity. A successful theory of quantum gravity will likely give a different answer for what the singularity of a black hole is.
