You don’t need to pay hundreds of thousands of dollars or sit through hours of classes in order to understand the fundamental nature of the universe. In truth, the fabric of the cosmos is just a mouse click away.

Hundreds of free videos have been made available by the world’s top universities, and they feature some of the leading physicists of our era. Here, we have compiled just a fraction of these in a kind of “guide to the cosmos” that will give you a basic overview of the key concepts in physics.

Huge thanks to the wonderful Moinak Banerjee for his work on this.
