Physics is the science of matter, energy, space and time. It looks both inward and outward, from the smallest subatomic particle to the vastness of the universe—and yet it is also intensely practical. Physics begins with the everyday physical world around us—the blue of the sky, the colors of the rainbow, the fall of an apple, the motions of the moon. What's happening here? Why do things work this way?

The big bang theory

In this video, Fermilab's Don Lincoln tells about the big bang theory and sketches some speculative ideas about what caused the universe to come into existence.

Is the Higgs boson really the Higgs boson?

The deputy physics coordinator for CERN's CMS experiment Darin Acosta explains what we know about the Higgs boson and what remains to be discovered. NSF funds the CMS (Compact Muon Solenoid) experiment, which is investigating a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.

The Higgs Boson explained

We visit particle physicist Daniel Whiteson at CERN, where he talks to us about what the mysterious Higgs Boson is and how the LHC Is going to find it.

A quantum entanglement

How do you make something that has never existed before? Physicists Jeff Kimble and Chen-Lung Hung take us on an exhilarating adventure of exploration.

Quantum computers animated

Theoretical physicists describe how things are different in the Quantum World and how that can lead to powerful quantum computers

A quantum experiment

Physicists Amir Safavi-Naeini and Oskar Painter describe how they were able to measure quantum motions of 1 femtometer (0.000000000000001 meters) in a micro-scale object.
