Why are Quantum mechanics and General relativity incompatible?
Probably some complicated mathematics going on? Right?

Your guess is correct. When both need to be applied at the same time (for example inside a black hole), mathematical nonsense results.MagnusM said:Why are Quantum mechanics and General relativity incompatible?

That's exactly the sort of thing that Quantum Field Theory is designed to deal with. And for other fields it does.Khashishi said:In GR, the metric of spacetime depends on the stress-energy distribution. In QM, you never know the energy distribution exactly.

The assumptions are incompatible. And by assuming a contradiction, you can derive absolutely anything. So in principle, any result you'd like, you can get. Want it to be too high, it can be made too high. Want it to be too low, it can be made too low. Mathematics is completely broken at this point.MagnusM said:Mathematical nonsense as in bizarre answers and something very different from reality?
Like gravity being predicted to be too weak or something like that?

Quantum mechanics and General relativity are two theories in physics that explain the behavior of the universe at different scales. Quantum mechanics deals with the behavior of particles at a subatomic level, while General relativity explains the behavior of objects at a larger scale, such as planets and stars.
Quantum mechanics and General relativity are considered incompatible because they have different mathematical frameworks and make contradictory predictions in certain situations. They cannot both be used to explain the behavior of the universe at the same time.
Scientists have been working on combining Quantum mechanics and General relativity for decades, but have not yet found a successful unified theory. This is because the two theories have fundamental differences that make it difficult to merge them into one cohesive framework.
The incompatibility between Quantum mechanics and General relativity has significant implications for our understanding of the universe. It means that there are certain phenomena, such as the behavior of black holes or the beginning of the universe, that cannot be fully explained using our current understanding of physics.
Yes, there is ongoing research and debate in the scientific community to find a way to reconcile Quantum mechanics and General relativity. Some theories, such as string theory or loop quantum gravity, attempt to bridge the gap between the two theories and create a unified understanding of the universe.
