General Relativity is the Curvature of Spacetime

WebJust to nitpick -- spacetime is never Euclidean, but can be pseudo-Euclidean. What you mean is that 4D spacetime is flat in the absence of mass-energy (that is, it is a Minkowski space). Einstein's general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. WebAug 15, 2015 · In the absence of an external force, objects travel along the straightest possible paths, geodesics, through spacetime. In the absence of gravity, those paths look like the straight lines we’re all used to. But in the presence of mass, they can look very curved. That, my friends is the gravitational “force.” And let’s be clear. It’s nota force!

WebNov 26, 2024 · Why does mass deform space-time? Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects. Does mass cause a space-time curve? WebSpace is indeed curved -- in four dimensions. Many people think the fourth dimension is simply time, and for some astronomical equations, it is. Einstein used time as a fourth dimension to describe a coordinate system called space-time.
