TED-Ed: These animals can hear everything | Jakob Christensen-Dalsgaard
The world is always abuzz with sounds, many of which human ears simply can’t hear. However, other species have extraordinary adaptations that grant them access to realms of sonic extremes. And some of them don’t even have ears— at least,...

The Universe Runs on Vibes
As much as we like to talk about vibes, actual vibrations underlie pretty much everything about the universe. From the patterns of galaxies created by the Big Bang to the existence of subatomic particles, here's how the universe runs on...

The WEIRD Way Monkeys Got to America
Many of the greatest biological dispersal events in history likely happened because animals inadvertently traveled across the oceans on floating debris.

How Long Can You Live Underwater?
In 2023, Joseph Dituri set a world record for the longest continuous stay underwater. And that 100 day stay had effects on both his body and mind. Scientists have been studying the effects of living underwater since the 1960s, but how...

Boom Boom Thump: How to Make Quieter Supersonic Planes
Supersonic jets like the Concorde face concerns over safety, high carbon output, and cost. They also make loud sonic booms so loud that only transoceanic flights are legal. Now one NASA program is trying to make a quiet supersonic plane...

This is How We’ll “See” the Universe’s First Second
In June 2023, scientists around the world announced the first official detection of the gravitational wave background — a cacophonous symphony of gravitational waves coming from every direction in space. Buried within that cosmic noise,...

The Snail We Misidentified More Than 100 Times
Everyone makes mistakes, but misidentifying a species more than 100 times? It happened. In this List Show, we tell the tale of the periwinkle snail and other creatures scientists confused for someone else.

Building Black Holes in a Lab
Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we...

Where Are The Worlds In Many Worlds?
Many Worlds interpretation of quantum mechanics proposes that every time a quantum event gets decided, the universe splits so that every possible outcome really does occur. But where exactly are those worlds, and can we ever see them?

Could LIGO Find MASSIVE Alien Spaceships?
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...

Breaking The Heisenberg Uncertainty Principle
Quantum mechanics forbids us from measuring the universe beyond a certain level of precision. But that doesn’t stop us from trying. And in some cases succeeding, by squeezing the Heisenberg uncertainty principle to its breaking point.

Gravitational Wave Background Discovered?
It was pretty impressive when LIGO detected gravitational waves from colliding black holes. Well we’ve just taken that to the next level with a galaxy-spanning gravitational wave detector that may have detected a foundational element of...

How to Communicate Across the Quantum Multiverse
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...

How Luminiferous Aether Led to Relativity
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...

When 90dB is LOUDER than 120dB
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.
