Episode notes
Supermassives As Galactic Heartbeats
- A supermassive black hole is a million to billions of solar masses found at galaxy centers.
- They act like a galaxy's heartbeat and can power quasars and massive jets affecting their surroundings.
Mystery Of Early Massive Black Holes
- Supermassive black holes are mysterious because of their huge masses and early appearance in the universe.
- They also actively influence galaxy evolution by ejecting gas and regulating star formation.
Schwarzschild's Frontline Discovery
- Karl Schwarzschild solved Einstein's field equations on the Russian front and found the first exact solution.
- He died shortly after without seeing black holes accepted as real astrophysical objects.
