I'm Cody Gough. And I'm Ashley Hamer. Today you learn about what Antimatter is and how we discovered it.

Then Dr. Jen Gunter, author of the Menopause Manifesto, who's also been called the world's

most famous gynecologist, will bust some myths about menopause.

Let's satisfy some curiosity.

In physics, the theories guiding the worlds of the very large and the very small have often been at odds.

And many prominent physicists have tried to unite them.

In 1928, Paul Dirac made an important first step to combine these theories,

and his work ended up predicting a completely new kind of material.

Antimatter.

Here's the weird story of what Antimatter is and how we discovered it.

Dirac was known as a very competent mathematician.

So when he tried to reconcile quantum theories Schrodinger equation

with Einstein's famous E equals MC squared from general relativity, he recognized something interesting was going on in the mathematics.

Instead of a single solution, there were two.

One solution corresponded to the electron, which is a particle we've known

about since the 1800s. The other solution predicted a similar but so far undiscovered particle. This new particle would have all the same characteristics

as the electron except for one. It would have a positive charge instead of a negative one.

Yeah, an electron with a positive charge.

At the time, it was imaginary.

To make his new theory work,

Dirac had basically come up with a make-believe particle,
