RaumZeitGefüge

Raumzeitgefüge is a term that can be translated from German to English as "spacetime fabric" or "spacetime structure." It refers to the concept of spacetime as a unified, four-dimensional continuum, encompassing the three dimensions of space and the one dimension of time. This notion is a fundamental consequence of Albert Einstein's theory of relativity.

In classical physics, space and time were considered separate and absolute entities. However, relativity revealed that they are interwoven and relative to the observer's motion. The "Raumzeitgefüge" is not a physical substance but rather a geometric description of the universe. Massive objects, such as stars and planets, warp or curve this spacetime fabric, and this curvature is what we perceive as gravity.

The curvature of spacetime dictates how objects move. Objects follow the straightest possible paths, called geodesics, through this curved geometry. The more massive an object, the greater its effect on the surrounding Raumzeitgefüge, leading to a stronger gravitational pull. This model has been extensively tested and confirmed through various astronomical observations, including the bending of starlight around the Sun and the precise orbits of planets. The concept of Raumzeitgefüge is central to our modern understanding of cosmology and astrophysics.
