Recent findings suggest that the fundamental constants might not be as stable as we assumed. And be sure to signup for your free trial of The Great Courses Plus at http://ow.ly/rcsA30beNw1

The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it’s hard to unravel the complexities of distant parts of the universe if we don’t know the basic rules. But what if this is wrong? There is a hint of evidence that the fundamental constants that govern our universe may evolve over time, and even from one location to another.
