What are the differences between Newtons Law & Einsteins Theory of General Relativity?
Newton defined gravity as a force, whereas Einstein described it as a curvature of space towards the dense object. EDIT: Here’s a way of thinking about it if you don’t understand: To visualize gravity as Newton proposed it, think of it like magnetism – a force which pulls objects together, except that with magnetism it’s only metal objects and with gravity it’s ALL objects. To visualize Einstein’s version, imagine a net attached to four posts. Drop a football on it, and what happens? The net sinks down where the football is. Now drop a tennis ball near the football and the tennis ball will roll towards the football, because the football has ‘curved’ the net towards itself. Furthermore, if you roll the ball in a straight line, it will start veering towards the side where the ball is when it gets to the dent (or ‘curve’), just like how objects trap smaller objects in orbit. The crucial difference is that in space there is no net, no friction, so while the friction of your net will eventu
