A Taste of Crush
Rats are afraid of heights. Listen to this excerpt from Crush to see how we discovered rodent acrophobia.
Snakes: Nature’s Gravity Experiment
Over hundreds of millions of years, gravity has changed snakes in different ways, depending on whether they live in the water, in trees, or on land.
What Happened to Hawking’s Theory of Everything?
For more than 30 years, Stephen Hawking pursued the ultimate Theory of Everything. Then, abruptly in 2009, he announced that there is no such thing, and he was OK with that.

Oppenheimer’s Biggest Blunder: Frozen Stars
One of J. Robert Oppenheimer’s greatest theoretical triumphs was also his biggest blunder.
The One Orbital Effect You’ve Never Heard of
It takes relativity to explain planetary orbits, but there’s one relativistic effect you’ve probably never heard of.
Could You Live Inside a Black Hole? (TL;DR: Yes, you could.)
Taking up residence in black hole might not be too bad, if it’s a rapidly spinning supermassive black hole.
Death by Black Hole? You might survive diving in after all.
You might survive a trip into a black hole afterall.
Gravity isn’t Geometry, according to Einstein
“I cannot agree with the widespread view,” Einstein once wrote, “that general relativity 'geometrizes' physics.”
Einstein’s Black Hole Error (and an Easy Fix)
Einstein didn’t believe in black holes. Here’s why.
The Black Hole in Your Kitchen Sink, Part 3 -Gravitational Lensing
Gravitational lensing is one hallmark of Einstein’s version of gravity know as relativity. You can do your own gravitational lensing experiments in the water flowing in your kitchen sink.
The Black Hole in Your Kitchen Sink, Part 2 -Experiments
Tinker with black holes, whites holes, and extreme gravity in your kitchen sink.
The Black Hole in Your Kitchen Sink, Part 1
A black hole is only as far as your nearest faucet.
