Black Hole Black Hole The general relativity view. Gravity is not a force. It is an effect caused by the curvature of space-time fabric. (Theory of  Space-time fabric is a 4D sheet, which gets bend or curved due to any mass or object. (Like a trampoline sheet gets bent when a heavy object placed over it) . Mass and energy are the same things. Heavier the object more the curvature in space-time hence more gravity.  I mentioned before that heavy object causes more curvature in space-time hence more gravity. Space-time is like a single elastic fabric made from the three spatial and one time dimensions. ( You can read my previous blog  gravity ). The object bends both space and time, and the bending of time component makes the clocks run slower in more gravity. Or you can say time is slower near heavy objects or planets or stars.  The flow of time changes due to the curvature of space-time. Now, a black hole is way heavier than our Sun making the time run even slower ar...
