Why is it difficult to take photos when the black hole is close

Astronomers released the first photo of the central black hole of the Milky Way galaxy, Xinhua News Agency (image provided by the event horizon telescope) the central black hole of the Milky Way galaxy is 27000 light-years away from the earth, and its size is about the same as the doughnut on the moon seen from the earth. To image it, we must ensure that the telescope is sensitive enough and the details that can be resolved are small enough, so as to ensure that we can”see” and”see clearly”.


What would happen if a primitive black hole hit the earth

If the modern universe had such a dense mass of matter, it would immediately collapse into a black hole. However, this does not mean that no black holes have been formed. Some areas happen to be very dense, and countless black holes may have been formed. We call these primitive black holes.
