I'd like you to take a look at this very interesting videos by NOVA featuring physicist Brian Greene, professor of Columbia University. They examine important topics of physics:
Quantum mechanics, with renowned professors from MIT, Stanford, Harvard, etc.
The Illusion of Time, a most see.
What is space?
Universe or multiverse? Which begins with a discussion of inflation.
