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...
What is so special about Gravity? Does know about gravity explains everything in the universe? I ain't going to explain to you the textbook description as it is boring and absurd. So, the special things about gravity are; it is somewhat strong and somewhat weak (Gravity is strong on Earth in comparison to on Moon, you might have heard or read that people float on Moon. I won't be giving you an example of Blackhole unless I explained you.) Newton's Idea of Gravity: He described gravity as a force of attraction between two objects as we are attached to Earth. He says if we know Speed and time, we can predict the future positions of any particle or object. So, his theory explains the motion of Earth, but later they found Uranus. Scientist recorded some deviation in the trajectory of Uranus around the Sun. So, here Newton's laws were failing, but they thought Newton could not be wrong. They recalculate the Uranus orbit by assuming a planet X which balance Newton's Gr...
