Testing What Exercise Actually Does to Your Butt
Cassey and I investigate the biomechanics of butts. What activates your butt muscles more, running or squatting? How effective are bridges as a butt workout? How much can we change the shape of our bodies with exercise?
Why Are There Giant Concrete Tunnels in the Desert?
The Physics Girl team visited LIGO once again. This place is Dianna's obsession.
What Happens When Black Holes Collide?
What happens when black holes collide? What is the speed of gravity? There are so many weird questions related to gravitational waves.
The Surprising Ways Mars is Hostile to Life
Wanna know all the reasons Mars will kill you and how we know? I hit up my friend Raquel Nuno who's a planetary geologist to find out.

Why This Stuff Costs $2700 Trillion Per Gram
There’s a factory in Europe that makes antimatter! It’s the rarest, most expensive, and potentially the most dangerous material on earth. Scientists don’t know why this material is so rare. Anti-atoms took 72 years after we discovered antimatter to make. Why?
How the Edge of Our Galaxy Defies Known Physics
How is it possible that you can't see 95% of the universe? The edge of our milky way defies known physics, so physicists are using the LHC at CERN to search for Dark Matter.
Inside the World's Largest Science Experiment
Dianna from Physics Girl visited CERN in Geneva Switzerland to find out what the detectors at the LHC are looking for, and dive into the fundamental question: what are particles?
This Thing is -270°C and is EVERYWHERE
In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming from everywhere in the universe. It turned out to be light from an unusual process 13.8 billion years ago.
