The Quest for a Theory of Everything in Quantum Physics

A “Theory of Everything” aims to unite all fundamental forces and particles under one framework.
Today, quantum mechanics and general relativity remain incompatible at extreme scales.
The four fundamental forces are gravity, electromagnetism, and the strong and weak nuclear forces.
Quantum field theory successfully unites three of them—but gravity resists.
String theory suggests all particles are tiny vibrating strings.
Loop quantum gravity proposes space itself is woven from quantum loops.
A true Theory of Everything could explain black holes and the Big Bang.
It might reveal hidden dimensions or new particles beyond the Standard Model.
Experiments with particle colliders and cosmic observations hunt for clues.
The quest for a Theory of Everything is one of the greatest scientific challenges of our time.
