Our two best theories of the physics of the universe – quantum mechanics and general relativity – often fail to agree. Physicists have been trying to unite them for over a century, and now, researchers have found one place where they don’t seem to clash. Working out from this one example may open the doors for building a more general, universe-wide theory.
