This is a map of the multiverse. Or in physics-ese, it’s the maximally extended Penrose diagram of a Kerr spacetime. And in english: when you solve Einstein’s equations of general relativity for a rotating black hole, the universe does...

A hydrogen atom is traveling high within the outermost layer of Earth's atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth's gravitational pull and escapes, joining the...

You and the professor have driven your DeLorean back to the past to fix issues with the spacetime continuum caused by your time traveling. But another DeLorean appears with older versions of you and the professor. The professors panic...

Nature can be pretty noisy, but there's some stuff that's just quiet all the time - right? Well, thanks to advances in audio equipment, researchers are finding out that everything from plants to bacteria have a lot more to say that we...

Humans may use fiber optic technology to make everything from novelty desk toys to high speed internet cables, but Nature has its own ideas. For decades, scientists have debated to what extent polar bears may use the optical properties...

Bumblebees fly, lights turn on, and you can ride a bike without falling over. We all know these things to be true, but what you may not know is the real reason behind why they work. Join Olivia to bust seven myths about motion.

For thousands of years, a sea creature has plagued sailors by attacking and devouring their ships. It is so destructive that reportedly it swiss-cheesed the hulls of Christopher Columbus’s ships, sinking at least two of them.

You may have had an ultrasound before, and wondered what that gel does. Well, that weird alien goop has a purpose, and it has to do with being like our weird human skin.

Hank talks about how warp drives could potentially work.

In which Hank celebrates the landing of the Mars Curiosity Rover, which, if you were following SciShow on Twitter, you know was pretty freaking cool. So here are the Top Five Coolest Things about the Mars Curiosity Rover!

Michael Aranda explains the nuts and bolts of Hyperloop, the new magnet-driven, solar-powered transit system proposed by Spacex genius Elon Musk. Learn how Musk answered three vexing questions to create the transportation of the future...

Long lines, metal detectors and pat downs are a common staple of the airport process. But are these security measures actually efficient and effective? Join Michael Aranda for a new episode of SciShow where he breaks down the science of...

If you ever get nervous about missile attacks, they're actually a lot harder to make than you might think. To hopefully put your mind more at ease, Hank is here to talk about the work that goes into designing and building ICBMs in this...

Fasten your seat belt as software engineer Alex Koster takes us on a journey in what he calls the "software dream car" of the future. He breaks down how massive technological shifts are transforming the automotive industry and paints a...

Jessi and Squeaks learn all about pine cones and their seeds today! Did you know that pine cones can open and close to help protect their seeds?

As Squeaks continues to prepare for his big trip with Jessi, Mr. Brown helps him learn all about different kinds of wings and how they help animals and machines fly!

By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate...
