PBS Space Time Season 2018 Episode 4 Kronos: Devourer of Worlds

Kronos: Devourer of Worlds is the 4th episode of PBS Space Time's 2018 season. This episode delves into the captivating world of celestial objects known as black holes. Black holes are one of the most mysterious phenomena in astrophysics, and their enigmatic nature has made them a popular topic of interest among scientists and the public alike.

The episode begins by explaining the basics of black holes, including how they are formed and what happens to matter that gets too close. It then focuses on a specific type of black hole known as a "spinning" or "rotating" black hole, which is also called a "Kerr black hole" after the scientist who first proposed its existence.

The episode explores how matter is pulled into a spinning black hole and how it interacts with the black hole's intense gravitational forces. The episode also explains how the phenomenon of "frame dragging" causes matter to spin around the black hole's event horizon and how scientists can use the gravitational influence of spinning black holes to study their properties.

Throughout the episode, experts in the field of astrophysics provide insights into the latest research on black holes, and how these findings shed light on some of the biggest mysteries of the universe.

Perhaps the most intriguing aspect of this episode is its focus on the effects of black holes on the fabric of space and time. It's well-known that black holes warp the fabric of space and time in their vicinity, but what exactly does this mean? This episode attempts to answer that question by exploring the concept of the "inner horizon" of a spinning black hole, and how it can cause time to slow down or even come to a complete halt.

The episode also delves into the concept of "ergospheres," the region surrounding a spinning black hole where matter is propelled outwards at incredible speeds. Experts discuss how these ergospheres could be harnessed to generate vast amounts of energy, making them a potential source of renewable energy in the far-off future.

Overall, Kronos: Devourer of Worlds is a fascinating exploration of one of the most enigmatic and awe-inspiring phenomena in the universe. With its clear explanations, stunning animations, and expert insights, this episode is a must-watch for anyone interested in the mysteries of the cosmos.
