2001: A Space Odyssey introduced a lot of people to the idea of rotation based artificial gravity, but in sci-fi, it’s far from the only one to implement the idea! Babylon 5, Halo, and Ringworld also used rotation-based artificial...

So, if gravity pulls everything down, then why don't things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabrina talks about gravity and explains that when we talk about gravity pulling...

The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as mythical as the grail of legend? What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? Or...

The holy grail of physics is to connect our understanding of the tiny scales of atoms and subatomic particles with that of the vast scales of planets, galaxies, and the entire universe. To connect quantum physics with Einstein’s general...

There are four fundamental forces - the strong and weak nuclear forces, electromagnetism, and gravity. Except maybe gravity is no more fundamental than the force of a stretched elastic band. Maybe gravity is just an entropic byproduct—an...

In nature, most of our basic forces both attract and repel. In fact, gravity is the only exception. But, according to theorists, sound waves actually have negative gravity.

Maybe you'd like to just hear about one topic for a while. We understand. So today, let's just watch some videos about Gravity. We'll learn about why we don't fly off into space, what mass has to do with it, how does air resistance work,...

This Quick Question explains the difference between gravity and g-force, and how you can experience zero-g in space even when it’s not zero gravity!

If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple theories that claim to do this, but it’s notoriously difficult to test them. They seem to require absurd...

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...

In this episode, we discuss the basic nature of gravity, one of the four fundamental forces in our universe.

What if there is no such thing as dark matter? What if our understanding of gravity is just wrong? New work is taking another shot at that Einstein guy. Let’s see if we’ve finally scored a hit with Modified Newtonian Dynamics aka MOND.

Einstein suggested that objects aren’t pulled by massive objects, but rather pushed down by the space above them. According to General Relativity, matter warps the fabric of not only space but time as well, collectively known as the...

We use a plumb line and hook to find the centre of gravity of an irregularly shaped piece of card. A hole is punched in the card and it is suspended from the hook. A plumb line is used to let us draw the vertical line under the hole on...

The closest thing we have to an all-encompassing framework that explains all particles and forces is represented by the Standard Model of particle physics. But this model is flawed because it does not...

Recent maps of the Moon's gravity have taught us a lot about its overall shape, and have been invaluable for lunar exploration. Maria Zuber, principal investigator of the Gravity Recovery and Interior Laboratory (GRAIL) mission, reflects...

The Gravity Recovery and Interior Laboratory mission, or GRAIL, consists of twin spacecraft in a polar orbit around the moon. GRAIL will map the moon's gravitational field by measuring changes in the distance between the two spacecraft...

Derive the acceleration due to gravity on any planet. Find the acceleration due to gravity on Mt. Everest. And determine how much higher you could jump on the top of Mt. Everest!

The force of gravity and the gravitational potential energy between an object and a planet is derived and graphed, inside and outside the planet.
