Question: What are the laws of physics ?

Arttu Rajantie answered on 13 Jun 2011:

General relativity and quantum field theory. Amazingly, we do not know of any phenomenon that could not be described with these two theories.

There are two caveats. First, if you actually try to describe some real phenomenon using these theories, the maths becomes so complicated that you usually cannot do it in practice. Second, the two theories are incompatible with each other, so we know that we must be missing something. So we are still trying to find the “theory of everything”, which would describe all phenomena.
