How does gravity bend light?
PhysicsRelativity
Quick Answer
Massive objects curve spacetime, and light follows that curved path. This effect is called gravitational lensing.
The Full Story
Albert Einstein’s general relativity, published in 1915, predicts that massive bodies bend the fabric of spacetime. Light moving near a galaxy, star, or black hole does not experience a force in the usual sense, but it follows the curved geometry. This can magnify distant galaxies, create arcs, or even produce multiple images of the same object. The effect was famously confirmed during the 1919 solar eclipse by observations led by Arthur Eddington. Gravitational lensing is now a major tool in astronomy for mapping dark matter and distant galaxies.
