Professor Fay Dowker: What is the problem of quantum gravity?

Einstein’s general relativity explains gravity, but it contradicts quantum theory – is there a solution to one of modern physics’ greatest problems?

This week, we’re going on a search for the theory of everything.

The two main theories of physics are at odds with one another. Einstein’s general relativity explains gravity, but it contradicts quantum theory: how we understand matter, atoms and particles.

Theoretical physicist at Imperial College London Professor Fay Dowker has been working on a solution to this quantum gravity problem, and tells us why the theories are incompatible, and how she plans to bring them together.
