Do Neutron Stars Shine In Dark Matter?
New ReviewNeutron stars aren't dark matter--we figured that out a while ago. But new research is telling us that they may be dark matter factories. They may produce the exotic axion, one of the most popular dark matter candidates.

The Final Barrier to (Nearly) Infinite Energy
New ReviewThey say fusion is 50 years away, no matter when you ask. Then why are billions suddenly being pumped into fusion startups? Yes to train LLMs, but there's a reason the technobrats are bullish on fusion in particular. The fact is, the...

What Would Happen If We Just Kept Digging?
New ReviewThe deepest hole we've ever been able to dig is just 0.2 percent of the way to the center of the Earth. What would we encounter if we could drill all the way? Correction: We mislabeled these! These are ammonite fossils, not trilobite...

What’s Below Absolute Zero?
New ReviewIt's impossible to have something colder than absolute zero...right? That's why it's called "absolute zero". Well, it turns out you can get certain substances to negative absolute temperatures (e.g. -1 Kelvin)...but in order to do so,...

Magnets: How Do They Work?
How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

The Alien Storm That Ate Itself
From cyclones to snowstorms, Earth is home to some spectacular weather events. But they're nothing compared to what you can find on the other planets in our solar system. Magnetic tornadoes? Ammonia mushballs? Let's (not literally) dive...

The Moon is Rusting. It's the Earth's Fault.
The Moon is typically 380,000-ish kilometers from the Earth, so it doesn't seem like they have that much of a direct influence on one another. However, the presence of hematite on the lunar surface suggests our planet is causing the Moon...
