Hi, I am a dummy in physics, my knowledge of physics is quite pathetic. Can anyone please explain to me the main idea, the essence, of the theory of relativity of Einstein in simple terms. I especially want to know how does it disprove the system of gravitation of Newton. Thank You.|||It doesn't disprove Newton, it simply provides a more accurate result that works for more complex systems.
Newtons law is generally only valid for near point masses in a generally isolated system. Once large distances and very large masses are involved, general relativity is better.|||The basic idea is this: that is all cases where you are moving at constant velocity (like v=0) the laws of physics still hold true.
Using Maxwell's equations of electricity %26amp; Magnetism you can show that the speed of light is the same no matter how you are moving relative(!!!) to other people. This means that things like time, mass, length, etc. are not constant, but relative quantities depending on who is measuring them.
General Relativity is essentially the same thing, but using more difficult math to show these relations when you are not moving at a constant velocity like acceleration.|||I can't do what you ask. Interestingly, Einstein said "If you can't explain something to a first grader, you really don't understand it yourself." Where does that leave me?|||Special or general?
