pervect said:there are other effects of curvature that don't fall into that description.
pervect said:frame-dragging effects (which don't, as far as I know, have an interpretation as tidal effects)
pervect said:the Topogravitic part, which has a reasonable interpreation as "curved space", but no interpretation in terms of tidal effects that I'm aware of
pervect said:I've noticed resistance and a lack of satisfaction when I try to explain the "gravity" of a moving body by explaining just its tidal forces.
General Relativity is geometry described mathematically.Phy_enthusiast said:...thus lacking pureness of geometry and mathematics.

Spacetime curvature refers to the bending or warping of the fabric of space and time caused by the presence of massive objects. It is a fundamental concept in Einstein's theory of general relativity and helps to explain how gravity works.
Spacetime curvature affects objects by causing them to follow curved paths in the presence of a massive object. This is why planets orbit around the sun and why objects fall towards the Earth. The amount of curvature is determined by the mass and energy of the objects involved.
Yes, spacetime curvature can be observed through various phenomena such as the bending of starlight around massive objects, the gravitational lensing effect, and the gravitational redshift. These observations have been confirmed by numerous experiments and observations.
Understanding spacetime curvature is crucial to our understanding of the universe as it helps to explain the behavior of gravity on a large scale. It also plays a significant role in the study of cosmology and the evolution of the universe.
No, spacetime curvature is not the only theory of gravity. There are other theories, such as Newton's theory of gravity, that have been successful in describing the behavior of gravity on a smaller scale. However, general relativity and the concept of spacetime curvature have been the most successful in explaining gravity on both small and large scales.
