Welcome


The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Science at Cal - Jason Dexter - Black holes - What do they look like?

Despite their dark name, black holes power some of the brightest objects in the Universe. Jason Dexter will discuss the observational evidence for the existence of black holes, the types of black holes that can be seen and the reasons why. What is an accretion disk that forms around a black hole? Jason will attempt to answer this question and others, as well as describe what the supermassive black hole at the center of the Milky Way will look like when Astronomers manage to image it in the near future.

Jason Dexter got his Ph.D. from the University of Washington, and is now a postdoctoral fellow in the Astronomy Department at UC Berkeley. He is interested in astrophysical black holes, and what we can learn from the light emitted by gas falling into them.
