Space Time Curvature
Faster things curve less.
Space time curvature. This does not mean that four dimensional notation is not useful. In the absence of gravity those paths look like the straight lines we re all used to. That s the curvature of space time.
That my friends is the gravitational force. General relativity generalizes special relativity and refines newton s law of universal gravitation providing a unified description of gravity as a geometric property of space and time or four dimensional spacetime. In qft gravity is a quantum field in ordinary three dimensional space just like the other three force fields em strong and weak.
What it means though is that a falling object follows a path called a geodesic. We still try it. In particular the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present.
The space time curvature is a key concept in albert einstein s theory of relativity. But in the presence of mass they can look very curved. How space time curvature works.
In 1 1 dimensional minkowski spacetime having one temporal and one spatial dimension the points at some constant spacetime interval away from the origin using the minkowski metric form curves given by the two equations. The answer in quantum field theory is simple. What exactly is meant by the concept of space time curvature is not so easy to explain.
Space is space and time is time and there is no curvature. Now of course it involves time as well as space so it s more complex than the rubber sheet thing.
