Einstein's theory of relativity fundamentally reshaped our understanding of gravity and the nature of the universe, building on and expanding upon [[Isaac Newton]] and his work on gravity. Newton's theory of gravity described gravity as a force that acted instantaneously across any distance, and was proportional to the masses of the objects and the distance between them. This theory worked well in explaining the behavior of objects in our everyday world, but it couldn't fully explain the behavior of objects at very high speeds or in extreme gravitational environments, such as around black holes. Einstein's theory of relativity, on the other hand, showed that gravity was not a force, but rather a curvature of space and time caused by the presence of mass and energy. This meant that the motion of objects was not simply determined by the forces acting on them, but also by the curvature of space and time around them. Einstein's theory of relativity also introduced the concept of time dilation, where time appears to slow down or speed up depending on the observer's motion relative to the object being observed. This concept has been experimentally verified and has significant implications for our understanding of the behaviour of matter in extreme environments, such as around black holes. Overall, Einstein's theory of relativity expanded upon and reshaped Newton's work on gravity, providing a more comprehensive and accurate understanding of the behaviour of matter and the universe. “God does not play with dice.” Of course he does! Or certainly we can’t be certain he doesn’t! Randomness is part of life… Ah, but after listening to [[Bernardo Kastrup]] I have to agree, that actually Einstein is probably right with this statement - What he means is that, what we call randomness, is actually just stuff that we don't know, but that there is a cause and effect behind everything.
