Space-Time Fabric: A Complete Overview The concept of space-time fabric originates from Albert Einstein’s General Theory of Relativity (1915). It describes how gravity is not just a force (as Newton thought) but rather the curvature of space and time caused by mass and energy. This explanation transformed our understanding of the universe. 1. What is Space-Time? The Four-Dimensional Continuum In classical physics, space and time were seen as separate entities: Space: A three-dimensional framework (length, width, height). Time: A separate, independent dimension that flows uniformly. However, Einstein’s Special Relativity (1905) showed that space and time are deeply linked, forming a four-dimensional continuum called space-time: 1. Three spatial dimensions (X, Y, Z – length, width, height). 2. One time dimension (T – the passage of time). Thus, events in the universe occur at specific points in this four-dimensional fabric, leading to the term space-time fabric. 2. How Does Gravity ...
