Q6. What phenomenon is thought to result from the collapse of massive stars into black holes?

Answers

A1. Albert Einstein

Because he developed the theory of general relativity, which describes the effect of gravity on the curvature of space-time and leads to the understanding of black holes.

A2. Event Horizon

Because it defines the region surrounding a black hole where the gravitational pull is so strong that escape is impossible for anything, including light.

A3. Solar Masses

Because it provides a convenient way to compare the mass of a black hole to the mass of our sun, using a familiar reference point.

A4. Messier 87* (M87*)

Because it was the first black hole captured in an image by the Event Horizon Telescope in 2019.

A5. Milky Way

In 2019, the Event Horizon Telescope captured the first-ever image of Sagittarius A*'s shadow, providing direct evidence of the supermassive black hole's presence at the galaxy's core.

A6. Supernova

Because the collapse of massive stars under their own gravity can lead to a supernova explosion, which occurs when the outer layers are expelled, leaving behind a black hole.
