What do we know about black holes?

The video explains black holes, focusing on two types: stellar-sized and supermassive. Stellar-sized black holes form from star explosions and have intense gravitational fields. Supermassive black holes, found in galaxy centers, have masses millions to billions of times that of the Sun. Despite their mass, they are small in size. The video dispels the myth that black holes will suck us in, explaining that their gravitational influence is only significant when very close. It concludes with the mystery of what happens to matter inside black holes.

What is the defining feature of a black hole that prevents even light from escaping?

• Gravitational pull

• Event horizon

• Stellar explosion

• Singularity

How do supermassive black holes differ from stellar-sized black holes?

• They are formed from star explosions

• They have a larger spatial scale

• They have a mass millions to billions of times that of the Sun

• They are found outside galaxies

Where are supermassive black holes typically located?

• In the center of galaxies

• In the outer regions of galaxies

• In the Milky Way's arms

• In the solar system

Why is it unlikely for our solar system to be sucked into the black hole at the center of the Milky Way?

• The black hole is too far away

• The black hole is too small

• The black hole has no gravitational pull

• The black hole is not in our galaxy

What remains unknown about black holes?

• Their formation process

• Their gravitational influence

• What happens to matter after it falls into them

• Their location in the universe
