Ethan Siegel, astrophysicist, author, science communicator, and educator, as well as a senior contributor for Forbes and other publications, delivers an insightful and thorough overview of space/time, black holes, and the physics that seeks to explain it all.
Siegel is an award-winning science writer and founder of the popular blog, Starts With A Bang.
And he has two books currently available, Treknology: The Science of Star Trek from Tricorders to Warp Drive, and Beyond the Galaxy: How humanity looked beyond our Milky Way and discovered the entire Universe.
Siegel discusses the recent black hole photograph, obtained by using Event Horizon Telescope observations of the center of the galaxy M87, that created a buzz around the world. As Siegel states, nothing will be the same in physics afterward.
He underscores the importance of this image. He states that the goal in science is to test and try to disprove, in order to cement theories. And Siegel explains, in great detail, how this image establishes the accuracy of Einstein’s theory of relativity and other scientific ideas. Siegel explains Newton’s theories and describes gravitational principles in regard to what we now understand about black holes.
The astrophysicist discusses the space-time continuum. He goes into detail about how space is being dragged faster than the speed of light in an event horizon, in regard to the acceleration of matter and differences of temperature. And he explains the fabric of space-time, in regard to what is happening in the event horizon, detailing information about the rotation of a black hole with an outer event horizon and an inner event horizon. Siegel explains the significance of these discoveries that again underscore the importance of the recent black hole photograph that Siegel states is one of the most consequential
moments in the science of the last decade.
