How exactly does curved space-time describe the force of gravity?
Today we will be talking about the Theory of Relativity and how exactly does curved space-time describe the force of gravity. So, basically, Einstein discovered that space and time can't be separated. They are part of the same thing, and gravity is actually produced by bending and warping this "spacetime", like a heavy ball sitting on a sheet of elastic. (for the simpler answer to the title's question look at the bottom of the page) Classical(or Newtonian) Physics Time can be considered as a dimension, just like distances. In this way, our universe is four dimensional: three for space and one for time. Before Einstein came along, people thought that these dimensions were fixed: anyone who looked at something would measure the same distances, see the same things happening at the same time. Special Relativity Einstein realised that this is not true. Two events that appear simultaneous to one observer may seem to happen at different times to a diffe...
