One thing I should point out is that Mr. Manley consistently gets Karl Schwarzschild's name wrong. It's Schwarz Schild (black shield) and pronounced more like shield (except the d is a t sound and it's a shorter i sound than in English) and less like the pronunciation in the video.YouTube
Black holes are weird. In particular the orbits as you get close don't behave like Keplerian orbits in Newtonian physics, which leads to many misunderstandings about how close you could get to a black hole. Many sci--fi writers make the mistake of presuming that the point of no return is the Event Horizon, when in fact there are limits even further out.
