Why Relativity Would Mess Up Car Headlights

The crew over at Vsauce has set out to answer a very important and critical question: would car headlights work at the speed of light? Unsurprisingly, the answer is not simple, but in the process, you do learn a lot about general relativity and photons and other sciencey stuff. » 2/26/15 11:08pm 2/26/15 11:08pm

Science Finally Answers: Could Kool-Aid Man Break Through A Brick Wall?

We've seen it happen time and again in commercials: a six-foot-tall pitcher of walking, talking Kool-Aid bursts through a brick wall, bellowing his trademark, "Oh yeah!" But could he really do it without completely cracking up? » 1/20/15 1:30pm 1/20/15 1:30pm

What If You Piled Every Human On Earth Into The Grand Canyon?

There are more than seven billion human beings living on Earth. That sounds like a lot until you imagine all of them sitting in a pile in the Grand Canyon. » 4/29/14 2:20pm 4/29/14 2:20pm

What would it look like from Earth if the Moon were a giant disco ball?

So, technically, this is what it would look like if the Moon were a disco ball AND orbited Earth at the same distance as the International Space Station, i.e. roughly 420 kilometers (260 miles) above the surface of the Earth. But that doesn't make it any less incredible looking. » 4/05/14 9:30am 4/05/14 9:30am

What makes creepy things creepy?

Lots of stuff frightens us that should frighten us – things that pose a clear threat to our physical wellbeing, for example. But what about things that just... creep us out? A shadowy visage, for example, or an almost – but still not quitehuman-looking robot? » 7/03/13 10:40am 7/03/13 10:40am

What would happen if Superman punched you in the face?

We did love the superhuman-on-superhuman violence in Man of Steel, but what if Superman were to launch his solar-powered fist at an ordinary human being? Vsauce gives us a lesson in comic book physics and explains why a Kryptonian punch would damage far more than just your face. » 6/15/13 9:00am 6/15/13 9:00am

What would happen if the Sun just... disappeared?

Many of you probably know that it takes light from the Sun a little over 8 minutes to reach Earth, so it would take us all at least that long to realize our parent star had vanished. But what would happen after that? » 3/31/13 10:00am 3/31/13 10:00am

What would happen if everyone on Earth jumped at exactly the same time?

If everyone on Earth stood shoulder-to-shoulder, they would occupy an area roughly the size of Los Angeles — about 500 square miles. Now imagine if every single one of them jumped. Together. All at the same time. What would happen? » 8/25/12 3:50pm 8/25/12 3:50pm

Try to get through this video on the science of yawning without yawning

This video, by vsauce, not only explains why yawning is contagious, but also lays out the physiology of yawning, reveals that you're less likely to yawn when your brain is cool, and gives us some delightful clips of parakeets yawning. » 5/20/12 1:00pm 5/20/12 1:00pm
