Your Body Was Forged in the Spectacular Death of Stars

Embark on a cosmic journey through the spectacular birth, death, and rebirth of stars in this 16-minute TED Talk by astrophysicist Enrico Ramirez-Ruiz. Discover how supernovas forged the elements essential for life, creating everything from the air we breathe to the very atoms that compose our bodies. Explore the life cycle of stars, nuclear fusion processes, and the formation of heavy elements like iron. Learn about computer simulations of supernova explosions and understand how atoms from ancient stellar events have taken residence in our bodies. Gain a deeper appreciation for the interconnectedness of all matter in the universe and the profound impact of stellar phenomena on our existence.
