General Relativity | Don't Miss That Window

General relativity, Albert Einstein's monumental 1915 theory, fundamentally reshaped our understanding of gravity. It posits that gravity isn't a force pulling objects together, but rather a curvature of spacetime caused by mass and energy. Massive objects warp the fabric of spacetime around them, and other objects follow these curves, which we perceive as gravitational attraction. This elegant framework successfully explained anomalies like Mercury's orbital precession and predicted phenomena such as gravitational lensing and black holes, later confirmed by observations like the 1919 Eddington expedition. Its implications stretch from the cosmic dance of galaxies to the precise functioning of GPS satellites, making it a cornerstone of modern astrophysics and cosmology.
