Is there anything faster than light?

Albert Einstein discovered that time is relative, meaning that when objects travel at, or close to the speed of light, distances stretch and time slows down. Learn more about light, time, mass, energy and the very fundamentals of the universe in these videos.

10 Ways to See into the Future: Time Travel

On Discovery Channel's "Assignment Discovery," learn about, what is perhaps, Albert Einstein's most startling conclusion, the mass-energy equivalence formula or E=mc squared. It states that energy and mass are linked with the speed of light.

Assignment Discovery: Mass Energy Equivalence Formula

On Discovery Channels "Assignment Discovery," learn how refraction occurs when light travels through a transparent medium affecting the speed and redirecting the light.

Assignment Discovery: Refraction Basics

Electricity and magnetism are related because they both result from the movement of electrons. Learn more about electromagnetic waves and the speed of light on Discovery Channel's "Assignment Discovery."

Stephen Hawking's Universe: A Walk In Time

Hawking uses a variation of the "grandfather paradox" to show why time travel can give cosmologists nightmares.

Stephen Hawking's Universe: Mad Scientist Paradox

In the future, a massive spaceship built for extreme velocities could accelerate to near light speed and travel into the future.

Stephen Hawking's Universe: Time Travel Starship

If we could ever open a massive wormhole, could it be used as a portal for journeys to distant planets or the deep past?

Stephen Hawking's Universe: Wormhole Voyages

Cosmic strings may be a way to travel trough the universe at the speed of light. Think of them as HOV lanes for space travelers.

Through The Wormhole: Cosmic Strings

This physicist is driven to try and construct an actual wormhole that is both predictable and has stable properties. What could go wrong?
2:26

Through The Wormhole: DIY Wormhole

This physicist describes the fluctuating properties of light as an experience similar to staring at a barcode on a juice carton while intoxicated.
2:03

Through The Wormhole: Double Vision

Because it's impossible to travel faster than the speed of light, mankind is eternally stranded inside the confines of our solar system.
