Exploring the Mysteries of Black Holes

What is one of the proposed ideas about the nature of singularities inside black holes?

• They are large, visible structures.

• They are wormholes connecting different universes.

• They are made of dark matter.

• They are composed of antimatter.

What happens to light as it approaches the event horizon of a black hole?

• It speeds up and escapes.

• It becomes invisible.

• It gets trapped by the black hole's gravity.

• It changes color.

What is the significance of the event horizon in a black hole?

• It is the center of the black hole.

• It is where time stops.

• It is the point where light is emitted.

• It marks the boundary where escape speed exceeds light speed.

What is the concept of holographic duality related to?

• The connection between particle theories and gravity.

• The interaction between light and sound.

• The relationship between time and space.

• The behavior of dark matter.

What is the main focus of the research team from the University of Michigan regarding black holes?
