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...

Why the Weak Nuclear Force Ruins Everything
The weak force has been causing trouble for a century, ruining everything physicists thought was true. But it might actually be responsible for your very existence.

TED-Ed: The battle that formed the universe | Fabio Pacucci
It's time for the biggest battle in the Universe: the Big Bang. In one corner is gravity— the force that brings all matter together. In the other is pressure— the force that can push matter away. Over the next several hundred thousand...

Feynman's Infinite Quantum Paths
There is a fundamental limit to the knowability of the universe. The Heisenberg uncertainty principle tells us that the more precisely we try to define one property, the less definable is its counterpart. Knowing a particle's location...

The Unreasonable Efficiency of Black Holes
This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not naturally-occurring. Chemical reactions...

Why Quantum Information is Never Destroyed
If you have perfect knowledge of every single particle in the universe, can you use the laws of physics to rewind all the way back to the Big Bang? Is the entire history of the universe perfectly knowable? Or has information somehow lost...

Are the Fundamental Constants Changing?
The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it's hard to unravel the complexities of distant parts of the universe if we don't know the basic rules. But what if this is...

Noether's Theorem and The Symmetries of Reality
Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And yet they're wrong - or at least they're only right sometimes. These laws are consequences of a much deeper, more fundamental...
