Hey, hey, short waivers, Emily Quang here.

It has been such a good week revisiting some of our favorite episodes featuring black scientists.

You've heard from geneticists Janina Jeff,

chemist Clarice Phelps, Horticulturalist Abre Lee.

And to close out the week, we are looking to the cosmos.

Our episode today features theoretical physicist Chanda Prescott Weinstein,

chatting with once upon a time and forever, short waiver, Maddie Sophia.

Enjoy and see ya on Monday.

You're listening to short waiver from NPR.

Once upon a time, there was a universe.

We are not sure about how it started or whether there is a reason.

We don't know, for example, if space time is ordered or disordered at the smallest scales,

which are dominated by the weirdness of quantum mechanics.

Then again, we are not super sure about this either.

For some reason, particles formed more matter than antimatter.

That process, which formed a particle type called barians, is called bariogenesis.

Chanda Prescott Weinstein is a theoretical physicist and author of the new book,

The Disordered Cosmos, a journey into dark matter, space time, and dreams deferred.

From there, those barians started to form structures and from those structures stars formed.

Then the stars got old and some of them died in super epic, rather fabulous fashion.

They exploded into supernovae, making heavy elements like carbon and oxygen in the process.

Those elements went on to be the basis for all life on Earth.
