This question examines the fundamental difference between Newton's view of gravity as an instantaneous force acting at a distance and Einstein's revolutionary idea that gravity arises from the curvature of spacetime. It seeks to understand why, in modern physics, the bending of spacetime by mass and energy is considered the true source of gravitational effects, rather than a mysterious force acting across empty space.
Newton's description can be shown to be a limiting case of the description of gravity as the result of spacetime curvature (in the non-relativistic limit, more precisely).
It would be a good idea to learn general relativity, there's no excuse not to learn it.
There are many lecture notes available. For example, Article Lecture Notes on General Relativity
Gravitational force has been shown to be an electromagnetic force due to recessional acceleration of the sun arround the centre of the galaxy in the scientific research paper titled 'Foundation of Theory of Everything Non-living Things and Living Things' which is available in my profile on ResearchGate.
Answer:
Because spacetime doesn’t carry gravity — it is gravity.
Newton thought gravity was a force — invisible, instant, and acting at a distance. But Einstein showed that what we call “gravity” is simply geometry. Massive objects don’t emit a force — they bend the fabric of spacetime, and other objects follow that curvature.
Why curvature causes motion (not force):
1. In Newton’s view, if the Sun were to disappear, Earth would somehow feel the loss of its gravitational pull instantly.
→ That violates causality and the speed of light limit.
2. In Einstein’s view, mass curves spacetime, and objects move along the straightest possible paths (geodesics) within that curved space.
→ Earth orbits the Sun not because it’s being “pulled,” but because the Sun bends the space around it, and Earth is simply falling through curved space.
3. That’s why light bends around stars — not because it’s heavy, but because the space it travels through is curved.
The best analogy:
You’re walking in a straight line on a curved surface — like a ball rolling on a trampoline. The ball doesn’t “know” it’s curving — it’s just following the local geometry. That curve is what we call gravity.
Einstein rewrote gravity’s identity:
Gravity is not a force.
It’s a symptom of spacetime trying to stay straight — in a universe where mass curves everything.
If Newton explained what gravity does, Einstein explained why.
And if you’re curious how wavefronts (like in quantum systems) may behave similarly under environmental curvature — well, that’s exactly what my theory, Quantum Wavefront Dynamics (QWD), is about.
Different scale — same principle:
Geometry governs behavior.
Dear Allwin K. Rex ,
In the article exists an answer to your question. The answer is similar in many ways to Einstein's answer.
Article The existence of the graviton can be proven physically and m...
While Einstein does not talk about action at a distance, but solves gravity mathematically, in the attached article a metaphysical concept hase been introduced to have reality as close as possible.

Answer:
The curvature of spacetime fundamentally cannot cause gravity, since, as that rigorously proven in the Shevchenko-Tokarevsky’s Planck scale informational physical model
https://www.researchgate.net/publication/395113364_Planck_scale_informational_physical_model_and_fundamental_problems_in_physics,
- Matter’s spacetime is fundamentally absolute, fundamentally flat, fundamentally continuous, and fundamentally “Cartesian”, (at l east) [4+4+1]4D spacetime with metrics (at least) (cτ,X,Y,Z, g,w,e,s,ct),
- which is fundamentally nothing else than a logical “empty container”, where everything in Matter exists and happens. The emptiness fundamentally cannot be impacted, including “curved”, by anything in Matter and impact on anything in Matter.
Gravity fundamentally is nothing else than some fundamental Nature force, which, as all other, i.e. Weak, Electric, and Nuclear/Strong, Forces, acts in the spacetime above; more about what are Gravity, Electric, and Nuclear/Strong Forces, which act on Planck scale essentially by the same scheme, see initial models of the Forces in section 6. “Mediation of the fundamental forces in complex systems in the link above.
Newton Gravity law is quite correct at statics, practically correct at bodies tens km/s velocities motions; and in rather weak Gravity fields; real complete classic Gravity Force theory must be developed basing on the initial SS&VT Gravity model above and take into account these cases.
