If the Sun Became a Black Hole Would Earth Fall In

The video explains that only massive stars can become black holes, while the Sun will turn into a red giant and then a planetary nebula. It discusses the properties of black holes, including their mass, size, and event horizon. The video reassures that replacing the Sun with a black hole of equal mass wouldn't affect Earth's orbit due to the unchanged gravitational pull. It highlights the importance of the event horizon and Schwartzschild radius in determining safety around black holes. The video concludes by emphasizing the stability of orbits around massive objects, regardless of their size.

What would be the consequences of being within the Schwartzschild radius of a black hole?

Discuss the implications of replacing the Sun with a black hole of equal mass on Earth's orbit.
