An Odyssey Through the Warped Side of Our Universe - Kip Thorne - 07/12/2024

Join us for this special 100th Stargazing Lecture, featuring Nobel laureate Kip Thorne. We host a 30-minute public-level lecture discussing black holes, quantum fluctuations, and other surprising, counterintuitive phenomena in our universe. The lecture is followed by a panel Q&A consisting of several astrophysicists to answer your questions about astrophysics and space science.

By this I mean objects and phenomena made from warped spacetime instead of from matter. In this lecture, I will describe some of what we have learned. For example: weird facets of black holes that you may not have not heard of before. And also likely new to you: voracious, ‘vacuum fluctuations’ — tiny bits of everything that ever could inhabit our universe, flashing in and out of existence, randomly. These fluctuations suck energy from rapidly distorting spacetime and use it to convert themselves into real, material stuff." Image Credit: NASA GSFC / Jeremy Schnittman
