What are Black Holes, and How are They Formed?

Question:

What are Black Holes, and How are They Formed?

Answer:

A black hole is a celestial object with an immensely powerful gravitational pull that prevents anything, including light, from escaping it. Due to their small size and the absence of light emission, black holes cannot be observed directly. However, they can be detected through the influence their intense gravity has on surrounding matter. Examples of black holes include Cygnus X-1 and Sagittarius A.

How Black Holes Are Formed?

The formation of black holes occurs when massive stars reach the end point of their life cycle. As the star dies, its core becomes unstable and collapses while its outer layers are expelled. The immense pressure from the collapsing matter compresses the star to the point where its volume becomes zero and its density becomes infinite.
