Episode notes
Milky Way's Supermassive Black Hole
- Our galaxy, the Milky Way, has a supermassive black hole at its center called Sagittarius A*, massing a billion times our sun.
- This black hole's gravity helps hold the galaxy together along with dark matter.
Gravity as Spacetime Curvature
- Gravity is not just a force but the curvature of spacetime caused by mass or energy.
- Spinning objects curve spacetime more, creating stronger gravity due to increased energy.
Micro Black Holes and Uniform Physics
- Micro black holes, possibly as small as molecules or planets, may exist from early universe times.
- Regardless of size, black hole physics remain the same according to current theory.
