In the early 20th century, Alfred Wegener's theory of Continental Drift laid the foundation for our modern theory of plate tectonics. And today we know something even more exciting: Pangea was only the latest in a long lineage of...

Black holes are the result of absolute gravitational collapse of a massive body: a point of hypothetical infinite density surrounded by an event horizon. At that horizon time is frozen and the fabric of space itself cascades inwards at...

An introduction to the quantum behavior of light, specifically the polarization of light. The emphasis is on how many ideas that seem "quantumly weird" are actually just wave mechanics, applicable in a lot of classical physics.

If you've ever been stuck at a red light on a country road, you know it can be annoying. No other cars for miles, but you can't shake the feeling that if you run the light, one will appear out of nowhere and slam into you. Today we have...

The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it's hard to unravel the complexities of distant parts of the universe if we don't know the basic rules. But what if this is...

Roller coasters give people the opportunity to experience physics in dramatic ways. In this episode of SciShow, we break down how physics work on roller coasters to give you the ride of your life!

There are a lot of ways to get around in space, from using plain old sunlight to making super-hot plasma. We’ve talked about a lot of propulsion methods over the years, and now, it’s time for some highlights!

Earth’s magnetic field is special! And, in the last 20 years, we’ve made incredible discoveries, thanks to a squad of probes that have flown around our planet, observing solar wind as a team!

Pulsed plasma thrusters use the same stuff that’s on your frying pan to make spacecraft zoom around the universe. And they’ve been doing it since the 1960s.

Our understanding of the world has to start somewhere! And while early ideas like the Hollow Earth Theory are mostly wrong and sound silly to us now, that doesn’t mean they weren’t important.

The way modern researchers study the sky hasn’t really changed in the last few centuries. For the most part, astronomers still study things by analyzing their light.

In 1944, amateur astronomer Hisako Koyama's latest endeavor was sketching the sun's shifting surface. She spent weeks angling her telescope towards the sun and tracking every change she saw with drawings. Little did she know, these...

How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called...

Dark Energy is what we call the mysterious force that seems to be pushing the universe apart. By some calculations, it makes up 70% of everything in nature. Or...maybe it doesn’t exist at all! Plus, Juno’s observations give us new...

Astronomers have found the first asteroid orbiting closer to the Sun than Venus, and recently, some scientists have been looking at Earth, trying to understand the origins of our protective magnetic field.

Life on Earth has always been shaped by other bodies in space, and life in our oceans is especially susceptible to interactions that have huge effects on life as we know it!

Scientists have revealed the results of the Parker Solar Probe’s first two flybys of the Sun, and LIGO has a new instrument called the quantum vacuum squeezer!

We've been making particle accelerators for more than a century and have accelerated particles to more than 99.9999% the speed of light. But our accelerators are nothing compared to some of the ones we've found in nature!

With so many claims about the moon’s influence over everything from menstrual cycles to rainfall, SciShow is here to set the record straight with these 8 truths and myths about our moon.

Good news for fans of Venus - last week, NASA announced two new missions to learn more about our planetary neighbor! And this week, NASA's Juno mission sent back a treasure trove of data about Ganymede - the largest moon in our solar...

Scientists have conclusively imaged a circumplanetary disk around a distant exoplanet, and Jupiter's auroras claim the spotlight with their unique Birkeland currents.

SciShow’s Executive producer Hank Green faces off against SciShow senior editor Alyssa Lerner in this Quiz Show about weird experiments and strange animal parts.
