The most massive stars in our universe—those at least 10 times more massive than our sun—shape the environments of the galaxies they live in. They're also responsible for producing heavy elements, which are necessary to create complex life forms (like humans). But how these burning behemouths come into being is a scientific mystery. This week on The Physics Central Podcast
I talk with physicist Paola Caselli
, a professor of astronomy at the University of Leeds, about how she and her colleagues are trying to solve massive mystery.
