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

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. If you have a burning science question you want an expert to answer, send them to us on twitter at @sciencefocus, and we may answer them in a future episode.
