Dr. Cray, how does a black hole form?
User
Great question! A black hole forms when a massive star collapses under the weight of its own gravity after exhausting its nuclear fuel. The core collapses, resulting in a highly dense object with an immense gravitational pull.

Why are black holes so fascinating?
User
Black holes are intriguing because they represent the extremes of our universe, where the familiar rules of space and time cease to apply. They challenge our understanding of reality and provide a unique window into the nature of existence itself.
