You've probably heard the rule that you cannot travel faster than the speed of light (in a vacuum). And this is true.

You may also have heard that you cannot travel precisely AT the speed of light. But this is false...because you...

This video unravels why tickling causes laughter and explores the concept of the stomach as a second brain, influencing our emotions. Discover the physiological and neurological responses behind being tickled and how our gut's complex...

Howcast - Learn how to order coffee in Italian with this Howcast video.

Why does the universe have an upper speed limit on the speed of light? Why isn’t the top limit infinite? Or what if the speed of light was not constant but changed in different reference frames?...

1930 - A new luxury cruiseliner hits the waters and begins escorting elite passengers from New York to Puerto Rico. Drafted as a military transport during World War II, she earns the name “Lucky Star” for never being struck by enemy...

If you travel at the speed of light, your mass will increase exponentially. The speed of light is 300,000 kilometers per second (186,000 miles per second). When you move at this speed, your mass will become infinite. Therefore, infinite...

You can break the speed of light in your back yard! (but don't worry, Einstein is still right)

Howcast - Learn how to say "how far is that" in Italian with this Howcast video.

All the light that we see are electromagnetic waves. All different wavelengths are equivalent, except that waves of higher frequencies are more energetic. The speed of all these EM waves, however, is the...

Not only do they describe every electrical and magnetic phenomenon, but hidden within these equations is a fundamental truth about the nature of light, and why it is the ultimate speed of the universe. We...

One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can we really be sure that the speed of light wasn’t different in the past, or perhaps in other parts of the universe? In...

Howcast - Learn how to say "I'm lost" in Italian with this Howcast video.

What is the purpose of light? How does light work? Why does Light exist? There had been a controversy about whether light was particles or waves. Albert Einstein showed that light must come in discrete packets of...

Summary:

If you point a powerful laser at the moon, and spin it 100 times per second, the dot on the moon will move 3X the speed of light. This is ok. The maximum speed limit is not a limit with which...

Howcast - Check out part 68 and go down to the Quarian homeworld, Rannoch, and destroy the Reaper Base in this walkthrough of Mass Effect 3.

We talked a little bit about relative motion in the classical physics course, with Galileo dropping stuff in boats. But once Einstein got his hands on relativity, he went a little nutty with it! The inertial reference frames are back but...

Psychologist and memory scientist Elizabeth Loftus (UC Irvine) describes how "memory repression therapy" began in the United States and was then somehow "exported" to the rest of the world.

The current NASA spacesuits use gas to maintain atmospheric pressure inside the suit. While necessary for the astronauts to survive, it makes the suits very difficult to work in. MIT astronautics engineer Dava Newman has developed a...
