14 Subatomic Stories: Where Einstein failed - quantum gravity

From the creator

Gravity is the most familiar of the forces and Einstein’s theory of general relativity describes it pretty well.  However, it fails in the subatomic realm and it will eventually need to be completely replaced by a new theory of quantum gravity.  In episode 14 of Subatomic Stories, Fermilab’s Dr. Don Lincoln talks about quantum gravity, including a couple of candidate theories.
