Theory of everything facts for kids
We do not have a theory of everything. It is a hope for the future. The basic concept of the theory of everything is that one theory could explain every aspect of physics. The four basic forces of nature are gravity, the strong force, the weak force, and the electromagnetic force. The theory of general relativity explains gravity, and quantum mechanics explains the other three forces. Right now, no one theory that everyone accepts can explain all four forces.
String theory is a theory that could become the "theory of everything".
