Stephen Hawking was considered by many to be the greatest scientist of his generation. He was brilliant and funny and authored a best selling book titled “A Brief History of Time.” He had ALS, a disease that led to his paralysis. But he was able to overcome his adversity and do great work as a scientist by using a speech-generating device with the muscles in his cheek. As a theoretical physicist, his work explored the mysteries of the universe and black holes and inspired millions of people. Listen to this story about Stephen Hawking’s life and accomplishments.

Supernovas happen at the end of a star’s life and then they fade away. Scientists are struggling to explain why one supernova has lasted for the past three years. During research, scientists found documentation from the 1950s that indicate this supernova was long-lasting back then. This discovery is challenging the established theories of how stars evolve. Listen to learn how scientists are rethinking their theories about supernova.

Our world is made of matter. Everything you see and feel is ordinary matter. Matter has a counterpart called antimatter. And true to science-fiction stereotype, if matter and antimatter meet, they destroy each other. Scientists are trying to find out why antimatter is so rare. One recent experiment took place inside a giant particle accelerator where scientists made small amounts of antimatter. After studying and measuring the forces of both antimatter and matter, they found that they behaved exactly the same. Listen to hear more about this discovery and why it matters.

Individuals who make extraordinary contributions to science often begin as regular people with a passion. This was certainly the case for Alan Guth, the physicist responsible for our understanding of how the universe formed after the Big Bang. Guth’s love for physics was sparked in high school and continues to drive his work today as a professor at MIT. Listen to learn more about his journey from a small town in New Jersey to physics textbooks around the world.
