In 2025, our YouTube audience spent nearly 16 million hours watching TED-Ed Animations (that’s equal to over 1,800 years!). Our most-viewed videos of 2025 include an exploration of dragon legends from around the world, tips on how to best build new skills, an explanation of why it’s a really bad idea to mess with a crow, a handful to help you understand your body, and more!
Qubits break quantum limit to encode information for longer | New Scientist

The odd phenomenon of quantum superposition has helped researchers break a fundamental quantum mechanical limit – and given quantum objects properties that make them useful for quantum computing for longer periods of time.
How 3 imaginary physics demons tore up the laws of nature | New Scientist

There is a long history of doing physics by imagination. Albert Einstein built his special theory of relativity after imagining himself chasing a beam of light. Erwin Schrödinger gave us a cat that was both alive and dead. The German mathematician David Hilbert demonstrated the counterintuitiveness of infinity by imagining a hotel with an infinite number of rooms and guests. By taking creative liberties, physicists use thought experiments to stress-test ideas and so better understand them.

Are we living in a simulation? This experiment could tell us | New Scientist

Thomas Anderson – otherwise known as Neo – is walking up a flight of stairs when he sees a black cat shake itself and walk past a doorway. Then the moment seems to replay before his eyes. Just a touch of déjà vu, he thinks. But no, his companions insist: he is living inside a computer program and he has just witnessed a glitch.
Quantum experiment finally settles a century-old row between Einstein and Bohr | New Scientist

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries of quantum physics: is light really a wave, a particle or a complex mixture of the two?

Black hole entropy hints at a surprising truth about our universe | New Scientist

Imagine you’re standing in front of a closed door. Behind it is a teenager’s bedroom, and your task is to rate how messy it is on a scale of 1 to 10. But here’s the twist: you can’t open the door – and you don’t even know what kind of stuff might be inside.
