PBS Space Time Season 2016 Episode 39 Black Holes from the Dawn of Time

In PBS Space Time season 2016 episode 39, titled "Black Holes from the Dawn of Time," the hosts delve into the mysterious origins of black holes and their impact on the universe. The episode first explores the concept of cosmic inflation, a theory that suggests the universe went through a rapid expansion period in its early stages. This led to the creation of primordial black holes, which are thought to be the smallest and oldest black holes in existence.

The hosts then move on to discuss the formation of larger black holes through the collapse of massive stars. They explain how the mass of the star determines what kind of black hole is formed and provide examples of observed black holes in our galaxy. But the episode doesn't stop there - the hosts examine the possibility of intermediate-mass black holes (IMBHs), which are believed to exist but have yet to be detected. They explain the potential impact IMBHs could have on nearby stars and galaxies.

The episode also explores the role of black holes in the evolution of galaxies. The hosts explain how supermassive black holes at the centers of galaxies act as gravitational anchors, driving the motion of stars and gas. They discuss the impact of black hole feedback, where energy from a supermassive black hole can cause an outburst of activity in a galaxy. This can create powerful jets of gas and can even shut down star formation in the galaxy.

Overall, "Black Holes from the Dawn of Time" provides an in-depth look at the fascinating world of black holes and their impact on the universe. The hosts use clear and engaging language, along with helpful visual aids, to explain complex concepts in an easy-to-understand way. This episode is a must-watch for anyone interested in astronomy, astrophysics, or the mysteries of the universe.
