Seeing real US Navy SEALs moving underwater is way cooler than any movie

This isn't a trailer for the next Tom Clancy movie. These are real U.S. Navy SEALs showing how they get into enemy territory from the sea.

Magician can guess the card you're thinking about through this video

Our eyes are too slow and our brains are too easily fooled. Just watch this video where Illusionist Eric Leclerc shows off by reading our minds through a simple YouTube video.

Carl Sagan explains why aliens are not visiting us all the time

If all the reports of UFO sightings are real, then Earth must be the most popular destination in the Universe. Obviously, that's a ridiculous anthropocentric notion, as Dr. Carl Sagan explains in the must-see 1966 CBS documentary UFO: Friend, Foe, or Fantasy hosted by Walter Cronkite. Listen to Sagan at the 51:55 mark. » 7/21/14 5:36pm Yesterday 5:36pm

Wow, all these rotating white dots are actually moving in straight lines

It looks like the white dots in this optical illusion are all orbiting an imaginary point in space that, at the same time, is orbiting the center of that red circle. They are not. In reality, they are all moving in straight lines going from one side of the red circle to the opposite one. » 7/21/14 4:08pm Yesterday 4:08pm

A new J. J. Abrams' Star Wars VII video shows a new version of the X-Wing starfighter. It may look like a Z-95 Headhunter because it doesn't appear to have the classic s-foils that open to give it it's X attack shape, but this official tweet says it's the real thing. So, ladies and gentlenerds, behold the X-wing Mark… » 7/21/14 8:35am Yesterday 8:35am
