Labels:text | screenshot OCR: BENDING LIGHT THE GENERAL THEORY of relativity indicates Actual Apparent position that gravitational forces are caused by position the curvature of space-time. Light rays travel in curved paths as they pass near any massive object. This is because they follow the curvature of space-time caused by that object's mass. Because a black hole has such an extreme concentration of mass, the space-time around it is bent to such an extent that even light cannot escape. CURVED STARLIGHT Light from a distant star is bent around the massive object, Massive object causing an apparent change in curves space-time | Light ray the star's position.
