Black Holes and Their Mysteries

The video discusses the discovery of massive black holes, their locations, and their connection to quasars. It explains why black holes are not visible due to galactic dust and how they can be detected through light distortion. The potential threat of wandering black holes to our solar system is also explored, highlighting the possible disruptions they could cause.

What is the estimated mass of the black hole at the center of the Milky Way galaxy?

• 2 to 4 million times the mass of the Sun

• 2 to 4 million times the mass of the Moon

• 2 to 4 million times the mass of the Earth

• 2 to 4 million times the mass of Jupiter

Why can't we see the black hole at the center of the Milky Way clearly?

• It is too far away

• It is moving too fast

• It is too small

• It is obscured by clouds and galactic dust

What are quasars believed to be?

• Distant planets

• Old stars

• Baby galaxies with raging black holes

• Clusters of asteroids

What is a possible reason we no longer see quasars in our galactic vicinity?

• They have been destroyed

• They have become quiet

• They have moved to another galaxy

• They have merged with other stars

How can wandering black holes be detected?

• By the distortion of light

• By their smell

• By their temperature

• By their sound

What is the main characteristic of a wandering black hole?

• It is stationary

• It is visible

• It emits light

• It moves through the galaxy

How is the detection of black holes similar to the function of glasses?

• Both emit light

• Both are visible

• Both distort light

• Both are heavy

What could happen to planets if a wandering black hole approached our solar system?

• They would shrink in size

• They would be flung into outer space

• They would stop orbiting

• They would become invisible

What is the potential impact of a wandering black hole on Earth?

• It could make Earth spin faster

• It could gobble up Earth

• It could make Earth invisible

• It could make Earth colder

What is the appetite of a black hole described as?

• Non-existent

• Enormous

• Moderate

• Small
