Space-Time Fabric

The concept of space-time fabric is a way of visualizing how gravity works according to Einstein's theory of general relativity. Imagine space and time as a flexible, four-dimensional sheet—like a trampoline or a stretched fabric—where objects with mass, such as stars or planets, create dents or curves. These curves influence the movement of other objects, causing them to follow curved paths, which we perceive as gravity. Larger objects make deeper dents, exerting a stronger gravitational pull, while smaller objects create gentler curves. This model helps explain how gravity affects everything in the universe, from planets orbiting stars to light bending around massive objects.
