WebJan 8, 2014 · Gravity is a consequence of the localised curvature of space. According to Relativity, space (space-time) is curved. So: Does the general curvature of space cause a gravitational force (or an anti-gravitational force where curvature is "convex") over inter-galactic and greater distances? WebSep 13, 2024 · This is not a distortion of spacetime, only of space, and the time part is essential in GR. It is a way to represent two-dimensional motion in Newton's theory as space curvature, but the laws are those of Newtonian gravity, not general relativity.

Is gravity caused by the curvature of spacetime? - Quora

WebIt is a central mathematical tool in the theory of general relativity, the modern theory of gravity, and the curvature of spacetime is in principle observable via the geodesic deviation equation. The curvature tensor represents the tidal force experienced by a rigid body moving along a geodesic in a sense made precise by the Jacobi equation. WebMar 15, 2016 · As to why warped space-time creates gravity, it's just from the distances themselves. Try doing this: (1) go step forward, then step right. (2) first step right, then step forward. In a flat space, you'll end up in the same position on both tries. In a curved space, this is no longer true. garland light bulbs

Q: Why does “curved space-time” cause gravity?: A better answer.

WebJan 27, 2024 · This is free fall, this is gravity, this is a large scale motion interpreted as a consequence of local curvature. Example: Original separation between \(\mathrm{A}\) and \(\mathrm{B}\)-and every other pair: 20 meters. Time of observation: 8 seconds. Shortening of separation in that time: 1 millimeter. Fractional shortening: 1 millimeter/20 meters WebGravity is not “caused” by the curvature of spacetime; it is the curvature of spacetime. Or so we think. Let me explain a bit further. It is, in fact, possible to interpret many theories geometrically. For instance, electromagnetism … WebOct 3, 2024 · What is space-time curvature? Is General Relativity the final say?

From the inside of each elevator, the situations are identical. WebSep 16, 2024 · But gravity can be called the curvature of spacetime when we want to describe it in terms of how matter determines gravity (to whatever extent it does). But these two notions don't agree with each other up to the extent allowed by gauge freedoms and propagating degrees of freedom." blackpink oldest to newest songsWebDec 19, 2013 · The two don't work together, they are competing descriptions of gravity. From a QM perspective gravity is mediated by the graviton. Picture gravitons encountering photons, imparting the force of gravity thus changing the photons' paths.

WebSo usually, people don’t say that velocity causes space-time curvature because it is a relative quantity. It is still an important point that moving objects do result in space-time curvature and therefore gravity – it is not possible for an observer to be at rest relative to all moving objects. This is true even without using General Relativity. WebGravity is a physical phenomenon. The curvature of the spacetime is an abstract mathematical concept. Some philosophers might argue that, whereas gravity exists in nature, spacetime curvature exists in our minds. Gravity is an intrinsic property of nature. The curvature of the spacetime is a mathematical model.

WebApr 27, 2024 · Consequently, we infer that the curvature interpretation of gravity does not describe the underlying natural phenomenon, but behaves as a mathematical tool to predict the natural phenomena correctly. WebOtherwise, let's just call the curvature "gravity". How do we reconcile this curvature, this gravity, with incredibly short distances and low energies, and quantization at those scales? ... Quantum field theory is well integrated with special relativity and can handle the time and space warping associated with the relativistic speeds of ...

WebSep 1, 2015 · The curvature of spacetime influences the motion of massive bodies within it; in turn, as massive bodies move in spacetime, the curvature changes and the geometry of spacetime is in constant evolution. Gravity then provides a description of the dynamic interaction between matter and spacetime.

WebApr 1, 2024 · Yes, this is Newton-Cartan gravity. It is a little different from General Relativity. It has a pair of degenerate metrics on spacetime, and the connection is a little more difficult to define. But it shares many of the same basic features of GR. Gravity is locally an inertial force. Inertial objects travel on geodesics.
