The presence of gravity greatly complicates the description of spacetime. In general relativity, spacetime is no longer a static background, but actively interacts with the physical systems that it contains.

Jul 31, 2025 · “What we experience as gravity is actually the curvature of space-time,” Medeiros says. This effectively means that time is slower the closer you are to an object with a strong gravitational pull.

Oct 24, 2025 · Whereas Newton thought that gravity was a force, Einstein showed that gravity arises from the shape of space-time. While this is difficult to visualize, there is an analogy that provides …

Einstein eventually identified the property of spacetime which is responsible for gravity as its curvature. Space and time in Einstein's universe are no longer flat (as implicitly assumed by Newton) but can …

May 4, 2022 · Albert Einstein taught us that space and time could warp and bend like a piece of fabric. This warping of the space-time continuum is what we experience as gravity. But Einstein’s theory is …

Sep 16, 2025 · Detailed observations of that light will provide stringent tests of strong gravity. General relativity also predicts that the inspiral of two massive objects will perturb spacetime and generate …

May 28, 2024 · Explore General Relativity’s role in understanding gravity, black holes, and the cosmos, from space-time curvature to gravitational waves. General Relativity, a theory developed by Albert …

May 24, 2025 · From the flowing arrow of time to the curvature that governs gravity, spacetime challenges our intuitions and invites us to see reality from a deeper perspective.

In general relativity (GR), concentrations of mass and energy curve the structure of spacetime, affecting the motion of anything passing near — including light.

Oct 29, 2024 · General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the theory of special...
