How is Einsteins idea of space and gravity different from Newtons?
Newton’s Idea of space was a fixed arena where all events played out all in a single refrence frame. For Newton, space and time were absolute. Einstein theorized and others later proved that all observers are in their own frame of reference and motion through space is observed differently for different observers. Even space itself was able to be warped or bent. No longer was space a backdrop for all events to take place in or for matter to exist in, now it was a dynamic and key player in events. I’ll be briefer with gravity. Newton decribes gravity as a force where Einstein said it was simply a warping, or indention created in space-time by the mass of an object which tends to cause matter or waves to follow this warped bowl likw path when near an objects gravitational influence.
