This Is Why Einstein Knew That Gravity Must Bend Light

WebLight is following a straight line. This path is called a geodesic. However, spacetime itself is curved by massive bodies. Therefore, an observer sees light as curving. In order for a body moving through curved spacetime to travel a path appearing to be straight from an observer, a force would have to act upon it.
