Physics
What can a theory of everything actually explain?
Quick fact
A theory of everything would attempt to unify quantum mechanics with gravity.
Why this is interesting
Physics has explained many parts of reality, but scientists are still searching for a deeper connection between them all.

Understanding What can a theory of everything actually explain?
Current physics has two extremely successful but incomplete descriptions: quantum mechanics for tiny scales and general relativity for large scales.
A deeper explanation
A complete theory may require new ideas about space, time, particles, and the fundamental structure of reality. Approaches such as string theory and quantum gravity attempt to solve this problem.
