why earth big and black
Answers
Explanation:
Black holes are just about the strangest objects in the universe. They are regions of space where gravity is so powerful that even light can't escape. Scientists call them holes, but they are anything but empty! They contain matter so compressed that their gravitational pull will not let even light leave them to reach our eyes and telescopes. That is why we cannot see them directly. But we are confident they exist because of the odd behavior of the matter we can see near them. For example, gases swirl around these regions at nearly the speed of light, giving off lots of high-energy radiation.
Black holes come in vastly different sizes. Some contain huge amounts of matter, some contain much less.
