The last hold out is gravitational waves - the idea that certain gravitational events cause actual ripples in Spacetime. The problem is that the effects are...

This movie of the March 6, 2012 X5.4 flare was captured by the Solar Dynamics Observatory (SDO) in the 171 and 131 Angstrom wavelength. One of the most dramatic features is the way the entire surface of the sun seems to ripple with the force of the eruption. This movement comes from something called...

Gravitational Waves Detected, Confirming Einstein's Theory: A team of scientists announced on Thursday, February 11, 2015 that they had heard and recorded the sound of two black holes colliding a billion light-years away, a fleeting chirp that fulfilled the last prediction of Einstein's general theo...

Brian Randolph Greene is an American theoretical physicist and string theorist. He has been a professor at Columbia University since 1996 and chairman of the World Science Festival since co-founding it in 2008. He stopped by The Late Night Show with Stephen Colbert to demonstrate an exciting new sci...

Residents and tourists in Montauk, New York, ventured out to the beach Saturday morning to get a glimpse of some of the waves and wind from Hurricane Irene which was still hundreds of miles away on Aug. 27.

For the next two years starting tonight, San Francisco's Bay Bridge will host artist Leo Villareal's magnificent installation "The Bay Lights", a shimmering LED sculpture that draws its inspiration from the bridge's surroundings - boats, waves, clouds, the city itself.
