The Science Asylum

Tidal locking is when the rotation of a planet or moon is equal to its orbital period. It's actually quite common in our solar system and likely elsewhere. How does that actually happen though?

Where are all the aliens?! This is the essence to the Fermi Paradox. It's most popular solution is the "Great Filter." What is the obstacle that life and/or intelligent species are unlikely to survive? Let's discuss.

Is the speed of light finite? Or is it infinite? That depends on what geometry you're using and how you define speed. It's infinite in hyperbolic geometry, which is the proper geometry for spacetime.

Entangled particles are the quintessential quantum object. They simply can't be explained by classical physics, but do they really communicate faster than light? In a way, yes.

Infrared light can allow you to see many normally invisible things, but can it allow you to see through walls? Let's take a look at the flow of heat using a thermal camera and also using a simulation based on the heat equation.

Supermassive black holes are pretty mind blowing. Some of them are larger than our entire solar system. The problem is, the universe isn't old enough for them to exist.

Bell's spaceship paradox from special relativity has been tormenting physicists for decades. I try to settle the debate once and for all with the use of spacetime diagrams.

About 107 years ago, Albert Einstein and David Hilbert published general relativity. It's the most modern model of gravity we have, but university courses on it are difficult to find. This video is a self-study guide.

Polarized sunglasses allow you to see the orientation of light. That combined with birefringence can help you see patterns of stress inside materials. But how does that work exactly?

The Star Trek transporter uses the concept of quantum teleportation, which should be physically possible. I asked other YouTubers whether or not they'd use one and we discussed the philosophical implications.

At about 9.6 billion light years, our intuition about angular diameter breaks down. Galaxies start getting larger the more distant they are. Let's find out why.

The circuit inside a microwave oven is a half-wave doubler, an incredibly inefficient design. How does it work? Why do we put them in microwaves?!

Ancient humans really wanted Earth to be the center of the universe. Geocentrism wasn't a mistake. Ptolemy wasn't that far off from the truth. He just gave Earth too much importance.
