Quantum mechanics is our best theory of the fundamental nature of reality, but it's usually only distinguishable from familiar classical mechanics on the smallest scales. However, there are some fringe cases where its distinct features manifest on scales we can observe—in things like superfluids, or the interiors of collapsed stars. But it’s also possible that our entire galaxy is filled with a re...

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 stuff. We’ve observed black holes colliding, and their oddly high masses challenges our understanding of black hole formation and grow...

The weird rules of quantum mechanics lead to all sorts of bizarre phenomena on tiny scales— particles teleporting through walls or being in multiple places at once or simultaneously existing and not. Shame all this magical behavior doesn’t happen on scales large enough for us to see...

Interstellar travel is horrible-what with the cramped quarters of your spaceship and only the thin hull separating you from deathly cold and deadly cosmic rays. Much safer to stay on here Earth with our gloriously habitable biosphere, protective magnetic field, and endless energy from the Sun. But what if we could have the best of all worlds? No pun intended. What if we...

The device you’re watching this video on is best understood by thinking about positive and negative charges moving around a circuit of diodes and transistors. But the only elementary particle actually flowing in the circuit is the negatively charged electron. And yet those flowing positive charges are th...

The deaths of massive stars results in one of the most beautiful and violent events in the universe: the supernova. They are so luminous we can see them here on Earth and historical records show that we can even see them into the day. But supernovas release...

We humans have always been explorers. The great civilizations that have arisen across the world are owed to our restless ancestors. These days, there’s not much of Earth left to explore. But if we look up, there’s a whole univ...

Astrophysicists have discovered a black hole that for millions of years has been blasting vast particle beams in opposite directions across the sky. And has recently swiveled to point its one of these jets directly at us. Is this an intergalactic death ray of an alien civilization that has suddenly noticed us? Absolutely not, and there’s no danger at all. But it’s a...

The humble proton may seem simple enough, and they’re certainly common. People are made of cells, cells are made of molecules, molecules are made of atoms, atoms are made of electrons, protons, and neutrons. And protons are each made of three up or down quarks. Simple stuff, right? All except for that last part. Protons are actually made of many, many quarks th...
