Dark Matter is the most abundant form of matter in the known universe, so what's keeping it from forming into planets?

It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those secrets may be revealed by turning...

When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and...

It may be that for every star in the universe there are billions of microscopic black holes streaming through the solar system, the planet, even our bodies every second. Sounds horrible - but hey, at least we’d have explained dark matter.

The possibility that a black hole could actually impact Earth may seem straight out of science fiction, but the reality is that microscopic primordial black holes could actually hit Earth. If one did, it wouldn't just impact like an...

Hunting for rogue planets is like hunting for an invisible needle in a haystack. But we're getting a much clearer view thanks to gravitational microlensing surveys. And it looks like there are a LOT more of them out there than we thought.

There are two types of rain, and one of them is almost impossible to forecast.

This video is about elastic and inelastic collisions in 1D, 2D and 3D - and how the collision of conservation of energy with conservation of momentum, plus a secret direction, results in a completely predetermined behavior for most...

You've heard of Breast Cancer, Skin Cancer, Colon Cancer, and many others. But this specific cancer was something entirely different—it took a research team five months to diagnose this specific cancer case, and that’s due purely to its...

The third and final part of the block collision sequence.

Some people try to attack things like evolution by natural selection and man-made climate change by saying "Oh, that's just a THEORY!" Yes, they are both theories. Stop saying it like it's a bad thing! It's time we learn the difference...

In this video Paul Andersen explains why astronauts are weightless. He also explains how Newton's Universal Law of Gravitation can be used to calculate the gravitational force between objects.

The insides of the our gas giant friend, Saturn, might be less of a mystery now that we’ve figured out how to use its rings to indicate its internal makeup. And the light emitted from some very old, very hungry black holes could be...

You've probably known OF E=mc_ since you were born, and were also probably told that it meant that it proved Mass equaled Energy, or something along those lines. BUT WAIT. Was E=mc_ explained to you properly? Mass equalling energy is...

The hunt for dark matter is still on, and the candidates for it could be primordial black holes as massive as Earth, or axions, as tiny as the smallest subatomic particles in existence!

Last week, seven earth-like planets were discovered orbiting a Red Dwarf star 39 light years away. Each one could be capable of supporting life.

The first time scientists found exoplanets, they were orbiting something very different from our sun: a pulsar.<br/>

Thanks to NASA's James Webb Space Telescope (JWST) project and the Space Telescope Science Institute for supporting this video.



This video is about the line between Brown dwarfs and gas giant planets (aka...

The medical industry has developed countless methods and tools for diagnosing the myriad of illnesses that can befall us. This, as you might guess, includes cancer. But it took a research team five months to diagnose this specific cancer...

Mercury’s path through our solar system is, well, a little eccentric, and some of its movements were a mystery astronomers couldn’t explain for a long time. Then, in the early 20th century, Einstein reran the numbers and proved a whole...

Playing with LEGOS is fun. But, they can also teach us something about matter. In this episode of Crash Course Kids, Sabrina chats about chemical reactions and the Conservation of Matter.

Neutrinos are weird. But all the big unsolved problems in physics are somehow connected to one unsolved mystery: Why do neutrinos have mass?

In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow.
