SUMMARY

The discussion centers on the necessity of unifying gravity with the other three fundamental forces: electromagnetism, the weak nuclear force, and the strong nuclear force. Participants argue that while unification has historically led to more accurate and elegant theories, gravity may inherently resist such integration due to its unique properties, particularly in extreme environments like black holes. The contradiction between quantum theory and general relativity is highlighted as a significant barrier to achieving this unification.

PREREQUISITES
  • Understanding of fundamental forces in physics

I am wondering why gravity needs to be unified with the other three forces into a super-force. Why can't the three forces be seen as interactions between particles in a space-time fabric whose geometry gives the impression of gravity?

It doesn't need to be unified with the other three forces. It's just that unification has, so far, led to increasingly accurate and arguably more 'elegant' theories. It's entirely possible that gravity simply cannot be unified with the other fundamental forces.

A basic problem is the inside of a black hole. Quantum theory and general relativity are in contradiction.
 
Thanks Drakkith and mathman. That makes sense, especially now that I've read a bit more about black holes.
