Understanding Supermassive Black Holes

The video discusses radio telescopes and their role in observing supermassive black holes, specifically focusing on the M87 galaxy and the Milky Way. It highlights the belief that most galaxies contain supermassive black holes, though recent studies suggest some exceptions.

Which collaboration is responsible for the direct observation of black holes using radio telescopes?

• Event Horizon Collaboration

• Galactic Observation Group

• Black Hole Research Team

• Cosmic Exploration Society

How does the mass of the M87 black hole compare to our sun?

• It is 6 billion times the mass of our sun

• It is 60,000 times the mass of our sun

• It is 6 million times the mass of our sun

• It is 600 times the mass of our sun

Where is the smaller supermassive black hole located?

• In a distant galaxy cluster

• In the Andromeda galaxy

• At the center of the Milky Way galaxy

• In the M87 galaxy

What is the general belief about the presence of supermassive black holes in galaxies?

• They are rare cosmic phenomena

• Virtually every galaxy has one at its center

• Only a few galaxies have them

• They are found only in large galaxies

What recent findings have been suggested about galaxies and supermassive black holes?

• Supermassive black holes are a myth

• Supermassive black holes are only in the Milky Way

• Some galaxies may not have supermassive black holes

• All galaxies have supermassive black holes
