Dark Energy, Cosmology part 2
The majority of the universe is made up of a currently mysterious entity that pervades space: dark energy. We don’t know exactly what it is, but we do know that dark energy accelerates the expansion of space. We think this means the...

The Tiny Planet Revealing Gravity’s Big Secrets
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...

How Big Are the Mountains on a Neutron Star?
The extreme mass of neutron stars leads to enormous gravitational pulls, resulting in nearly perfect spheres. But those imperfections, or mountains, might be able to help us spot more neutron stars in the future! And back on Venus, more...

Designing a Trial
It's time to design some trials. Sometimes engineers need to figure out how to test ideas. In order to do that, we need to design trials to find failure points and see how things are going to work in the real world (with gravity, wind,...

Reinventing the Wheel: 5 Species That Roll
If wheels and rolling have proven so efficient for humans, why hasn’t evolution pushed at least some other species in that direction? Well actually, there are a few species that can get around by rolling. Chapters View all GOLDEN WHEEL...

Gravitational Mass
In this video Paul Andersen explains how the gravitational mass is a measure of the force on an object in a gravitational field. The gravitational mass is based on the amount of material in an object and can be measured to a standard kg...

Gravitational Force
In this video Paul Andersen explains how an object with mass placed in a gravitational field experiences a gravitational force. On the Earth this gravitational force is known as weight. The gravitational force is equal to the product of...
