NASA's new frontier, and the Trouble with "Gravity"
Hank describes how astronomers used a technique called gravitational lensing to find the most distant galaxy ever detected -- and how NASA is embarking on a new program to use this same technique to peer deeper into space than ever...

The Phantom Singularity
Isaac Newton's Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton's equations. They don't always accurately...

Einstein's Biggest Blunder, Explained
This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the problem by introducing the cosmological...

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...

The Man Who Corrected Einstein
This video is about how Russian physicist Aleksandr Fridman corrected Albert Einstein about the expansion of the universe. Einstein thought that general relativity implied that space had to be static and unchanging, but he had made a...
