Topic: Exploding Stars, Dark Energy, and the Runaway Universe
Speaker: Dr. Jeffrey Silverman
Some of the most energetic and fascinating objects in the Universe are exploding stars known as supernova. These colossal outbursts result from the deaths of stars and for a time can outshine the entire galaxy in which they're found. Elements necessary for life are built up in stars during their lifetimes and are spread throughout space during these supernova explosions. Observations of distant supernova provided the first evidence that the expansion of the Universe is speeding up with time, rather than slowing down. This wholly unexpected phenomenon is likely due to a repulsive "dark energy" and has become one of the biggest unsolved mysteries in modern science.
Jeffrey Silverman is Director, Data Science & Analytics at Samba TV where he uses Big Data to, among other things, figure out exactly how many people are watching Game of Thrones. Before moving into the tech industry, Jeffrey was an NSF Astronomy & Astrophysics Postdoctoral Fellow at the University of TX at Austin and he earned his PhD at UC Berkeley working on supernovae and dark energy with Prof. Alex Filippenko. Jeffrey is also heavily involved in various science communication and public outreach programs including co-hosting Big Screen Science, a monthly movie showing followed by a science presentation at the Alamo Drafthouse Cinema in San Francisco.
