Question

Quizplus · Accepted Answer

The tremendous activity detected at the center of the Milky Way Galaxy can be best explained by the presence of a supermassive black hole. This object is thought to have a mass of about four million times that of the sun and is responsible for the strong gravitational forces that cause stars to orbit around it at high speeds. The black hole also feeds on surrounding gas and dust, leading to intense bursts of energy and radiation that can be detected by telescopes. This activity is consistent with what we observe at the center of our galaxy, supporting the idea that a supermassive black hole is present there.
