Whenever we open a new window on the universe, we discover things that no one expected. Our newfound ability to measure ripples in the fabric of spacetime—gravitational waves—is a very new window, and so far we’ve seen a lot of wild...

In the Many Worlds interpretation of quantum mechanics, the universal wavefunction is the reality, encompassing all possible histories and futures and all exist. But we are only sensitive to a slice of the wavefunction corresponding to...

As the 19th century came to a close, physicists were feeling pretty satisfied with the state of their science. The great edifice of physical theory seemed complete. A few minor experiments remained to verify everything. Little did those...

The double slit experiment radically changed the way we understand reality. Find out what the ramifications of this experiment were and how we can use it to better comprehend our universe.

Ocean currents are our planet’s circulatory system, and they keep everything from ecosystems to the climate healthy. But we’re changing Earth in ways that threaten to disrupt and even break critical ocean currents like the planet-wide...

Hurricanes, typhoons, and tropical cyclones are Earth’s most powerful storms, capable of unleashing destruction and death on coastal areas worldwide. As climate change warms Earth’s oceans, we face more risk of storms rapidly...

We often use decibels, a measure of sound pressure, to describe how loud something is - but loudness is caused by how we perceive sounds, and the two often don't line up.

This video is about the "Kelvin wake" shape of water wakes behind boats - we talk about mach angle, dispersion, superposition of many waves, and how these all lead to the pattern of a wake. We don't get into Froude number though...

For thousands of years, sailors have been telling stories of a mysterious phenomenon called dead water. Even after scientists figured out why it happens, it still affects swimmers today.

Olympic National Park is temporarily closed as Washington, the US, and the world work to mitigate the spread of the COVID-19 virus. We filmed this series in early January and are currently at home practicing social distancing. We hope...

Until now, researchers have assumed that healthy cells switch off the enzyme telomerase as a way to protect themselves from turning cancerous. But a new study suggests the enzyme may have a healthier role than we previously thought....

Units are a major way we describe the world around us, and by looking at the scientists some of them are named after, we can get a sense of how we’ve learned so much about our universe.

When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

This week's SciShow news has Hank bringing us a primer on the science behind various illegal and illicit ways in which athletes "improve" their bodies, proof of general relativity that we can actually see, and a new way to measure how...

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.

Singing in the shower seems to sound better, but what is actually happening to the sound waves in that soapy, tiled room?

Scientists think they’ve discovered some peaks taller than Mt Everest deep beneath the earth’s crust, and this range might be the key to one of the biggest mysteries in geology!

There are some geological areas on the planet that scientists still don't understand. For most things it's pretty clear—combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on...

If you want to make particles move really fast, you have to build a particle accelerator that is really big, right? Not anymore! Hosted by: Hank Green

While many of us have heard of white noise, did you know there are a myriad of other color noises that can help with sleep, relaxation and focus? Join Michael Aranda for a new episode of SciShow, and learn which color noise might be just...

Modern life runs on wireless technology. What if the energy powering our devices could also be transmitted without wires? Electrical engineer Ali Hajimiri explains the principles behind wireless energy transfer and shares his far-out...

Long ago, the Hawaiian wind goddess wielded a gourd that housed the winds of the Islands. It came to hold her bones, along with the life force they carried, and was eventually passed to her grandson, Paka'a. Like his father before him,...

Squeaks is back from visiting Sam the Bat’s cave and is excited to learn all about how different caves form and why they look the ways they do!
