Singularities frustrate our understanding. But behind every singularity in physics hides a secret door to a new understanding of the world.
What do we mean by a black hole’s size? A photon sphere? The minimal stable orbit? The event horizon? The singularity? Which one is right?
The multiverse is an idea that has gained a lot of traction in popular culture. But what does science have to say about it?
Explanations for the cosmic speed limit often conflate mass with inertia.
The outer planets’ clouds hide the weirdness within.

The transformational change driven by AI will elevate neurodiversity inclusion as an organizational asset, argues Maureen Dunne.
It’s the origin of our entire observable Universe, but it’s still not the very beginning of everything.
Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?
Finding out how the Universe grew up was the biggest science goal of JWST. This ultra-early proto-galaxy cluster is one amazing discovery.
After 15 years of monitoring 68 objects known as millisecond pulsars, we’ve found the Universe’s background gravitational wave signal!
“Even with my training, I still got insights from the book’s descriptions. That’s how good Carroll is at explaining physics.”
An average undergraduate student in physics is better than the AI.
Some constants, like the speed of light, exist with no underlying explanation. How many “fundamental constants” does our Universe require?
Realizing that matter and energy are quantized is important, but quantum particles aren’t the full story; quantum fields are needed, too.
The hyperloop would be a great idea for a completely flat planet. With topography and infrastructure, it’s a very different story.
