Exploring Black Holes

What is the photon ring in the context of a black hole?

• A ring of stars orbiting the black hole

• A magnetic field around the black hole

• An image produced by light that has orbited the black hole

• A physical ring of gas surrounding the black hole

How does the camera's speed affect the light sources in the simulation?

• It has no effect on them

• It causes them to dim

• It makes them disappear

• It causes them to brighten greatly

What causes the starry sky to appear distorted and mirrored in the simulation?

• The speed of the black hole's rotation

• The black hole's magnetic field

• Light making multiple orbits of the black hole

• The camera's lens is faulty

What is the significance of the successive bands in the photon ring?

• They are distorted images of the gas disk

• They represent different colors of light

• They are layers of gas clouds

• They indicate the speed of the black hole

How long would it take a typical laptop to compute the black hole simulation?

• More than a decade

• 5 days

• A few hours

• One year
