How To Detect Faster Than Light Travel
Warp drives may or may not be possible, but if they are then could a distant alien civilization’s warp fields produce gravitational waves that we could see here on Earth? According to a recent study.. Actually maybe, at least eventually....

Was the Gravitational Wave Background Finally Discovered?
A few weeks ago a large team of gravitational wave astronomers announced something pretty wild. The moderately confident detection of pervasive ripples in the fabric of space time that presumably fills the cosmos, detected by watching...

Why A 4.8 Magnitude Earthquake Isn’t Always A 4.8 Earthquake
The New Jersey earthquake of 2024 might have felt bigger than ones of the same magnitude on a Richter scale or intensity in California. That's because earthquakes in the eastern US go farther and hit harder than their western...

These Islands Shouldn't Exist
You've probably heard that climate change is leading to rising sea levels, which is bad news for lots of islands. But for some islands like the Maldives, rising waters are making them... bigger? Correction: We mixed up east and west!...

The Effects of Climate Change: Crash Course Biology #9
Climate change shakes up all of Earth’s systems, including the living ones. In this episode of Crash Course Biology, we’ll see how climate change’s effects rattle the entire chain of life. Changes felt in one population ripple out to...

The Deadliest Thing At The Beach
You might think the most dangerous thing that can happen at a beach is a shark attack, or that the scariest thing might be a tsunami - but instead, rip currents kill more beachgoers than all other causes combined.

TED: Could we replace data centers with … plant DNA? | Cliff Kapono and Keolu Fox
Is it possible to meet the world's seemingly infinite demand for data storage while also caring for the natural environment? Biomedical researcher Keolu Fox and professional surfer and scientist Cliff Kapono believe that Indigenous...

TED: Our savory, spicy, significant relationship with food | June Jo Lee
Exploring the rich meaning behind what we choose to eat, food ethnographer June Jo Lee unpacks how our "modern hungers" — or our deepest desires and need for connection — inform every bite. She decodes what Gen Z's palate says about the...

Gravitational Waves Explained Using Stick Figures
This video is about gravitational waves in the weak field limit as discovered by the LIGO collaboration, explained by parallels to electromagnetic radiation, sound waves, water waves, etc. I want to see Cat LIGO ASAP!

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...

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...

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.

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?

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...
