Los agujeros negros

The video explains the formation of black holes from collapsing stars, where the core's mass exceeds four times that of the Sun, leading to a singularity. The event horizon marks the boundary beyond which nothing can escape the black hole's gravity. Accretion disks around black holes can emit radiation jets. Despite their reputation, black holes do not consume everything around them. A massive black hole is believed to be at the center of the Milky Way, with others scattered throughout the galaxy. The closest known black hole is 1600 light-years away, posing no immediate threat to Earth.

Explain the role of the accretion disk in relation to black holes.

How would the presence of a black hole with the same mass as the Sun affect the Earth and other planets?
