Scientists are buzzing about gravitational waves and what a big deal they are. Wait! Don’t be embarrassed if it all leaves you confused and you just can’t share their excitement. Here's your guide to gravitational waves, short and simple as ABC.

fter a decades-long quest, The MIT-Caltech collaboration LIGO Laboratories has detected gravitational waves, opening a new era in our exploration of the universe.

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...

For the past 90 years, the predictions laid out Einstein's general theory of relativity have continued to be confirmed by experimental science. 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...

How big can they get? What's the largest so far detected? Where does an 18 billion solar mass black hole hide? We've never seen them directly, yet we know they are there. Lurking within dense star clusters or wandering the dust lanes of the galaxy. Where they prey on stars. Or swallow planets whole....

A coor versionof Albert Einstein Explaining E= MC^2, Real Speech.

A mysterious and intense X-ray source near the black hole shines onto the surface layers of the accretion disk, causing iron atoms to radiate characteristic emission -- what astronomers call the iron K line -- at about 6,000 to 7,000 electron volts. The inner part of the disk is orbiting the black h...

According to ancient astronaut theorists, Ramanujan, the mathematician who lived almost a hundred years ago and whose breakthroughs helped form the basis of superstring theory and multidimensional physics, claimed to have been influenced by otherworldly beings in this clip from Season 11, Episode 5,...

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...
