What If Gravity is Not Quantum?
New ReviewThe holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't feel bad because it turns out that...

Gravitational Waves Explained Using Stick Figures
This video is about gravitational waves in the weak field limit as discovered by the LIGO collaboration, explained by parallels to electromagnetic radiation, sound waves, water waves, etc. I want to see Cat LIGO ASAP!

Do Photons Cast Shadows?
This video is about two-photon (gamma-gamma) physics, and how photons can interact with each other - either mediated by a passing lepton, or gravitationally via lensing, or via vacuum fluctuation pair production of vertical particles...

The Mysterious "Space Roar"
We here at SciShow like to start things off with a "Boom" for yet another season! Hank talks about the mystery behind the "Space Roar" and why it is we can't really hear it.

Electromagnetic Waves
In this video Paul Andersen details the characteristics of electromagnetic waves. Electromagnetic waves are transverse waves that can move through both mediums and vacuums. The electric and magnetic fields oscillate perpendicular to the...

Electromagnetic Radiation
In this video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays, infrared...

How We Know Star Wars Isn’t A Documentary | Compilation
Plot often trumps reality when portraying space in movies and, as a result, many films are full of inaccuracies. So how much fiction is actually written into some of our favorite movies? Movies mentioned (and potentially spoiled) in this...

Mechanical and Electromagnetic Waves
In this video Paul Andersen compares and contrasts mechanical and electromagnetic waves. Both types of waves transfer energy through oscillations but mechanical waves requires a medium. Several examples of each type of wave are included.

Why Is the Speed of Light Limited—and What If It Weren’t?
New ReviewWhy does the universe have an upper speed limit on the speed of light? Why isn’t the top limit infinite? Or what if the speed of light was not constant but changed in different reference frames? The speed of light is dependent on two...
