The Particle So Extreme Scientists Called it OMG
In 1991, a subatomic particle smashed into Earth's atmosphere traveling faster than anything humans can replicate. It's the most energetic particle detected to date, and maybe even the fastest (except light itself). Astronomers call it...

How To Go Faster Than Light Speed (Seriously…)
Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past that speed limit, creating a stunning glow called Cherenkov radiation. We can see this glow in a nuclear reactor as...

When Is Now?
When is now? Seems like a pretty simple question… just look at your watch. But do you and I share the same “now”? Let’s journey from Einstein’s thought experiments about relativity to cutting edge neuroscience research to try and answer...

New Results in Quantum Tunneling vs. The Speed of Light
Paradoxically, the most promising prospects for moving matter around faster than light may be to put a metaphorical brick wall in its way. New efforts in quantum tunneling - both theory and experiment - show that superluminal motion may...

From Thunderstorms to Black Holes: 4 Natural Particle Accelerators
We've been making particle accelerators for more than a century and have accelerated particles to more than 99.9999% the speed of light. But our accelerators are nothing compared to some of the ones we've found in nature!

Why Scientists Keep Trying to Break This 18th Century Law
It’s usually not a great idea to break laws, but breaking the laws of science is an exception! In fact, it’s often how we make progress.

Blazars Are A Thing
Hank explains how quasars and blazars are both the same thing - just oriented differently in respect to us - and how that impacts the way we perceive them and how it also effects the ways we can study them.

How To X-Ray A Black Hole
Black holes are everywhere, including at the center of our galaxy. But because they’re invisible they’re quite difficult to study. Looking at the disks of material surrounding them, however, can give us tons of clues about how they...

How Jupiter’s Moons Showed Us the Speed of Light
Light travels through space as fast as anything in the universe possibly can, but before scientists could figure out light’s speed, they had to figure out whether that speed was even finite.

Black Holes
We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar mass black holes form when a very massive star dies, and its core collapses. The core has to be more than...
