Why is the universe flat?
Cosmic inflation is a theory that was proposed in the 1980s by cosmologist Alan Guth to answer some of the most fundamental questions of the origins of our universe. It also solved the Horizon Problem and the Flatness Problem.

Star and Galaxy Formation in the Early Universe
Okay, so we are about 150 million years into the lifetime of the universe. We've got a bunch of hydrogen and helium and not much else. But then gravity takes over, and boom! We've got stars! How, you ask? Well you'd better watch this!

Gravity Assist: Freaky Physics on the Space Station, with Ethan Elliott
The laws of physics get very, very weird in the realm of particles too small for the eye to see. Aboard the International Space Station, an experiment called the Cold Atom Laboratory (CAL) is exploring how the universe works .
