Why is light affected by gravity even if it doesn't have mass?
user
Light doesn't have mass but still have energy, and according to general relativity, gravity affects anything with energy, therefore gravity still affects the path of light, but not the speed.

Can you concisely explain General Relativity?
user
General Relativity, formulated by Albert Einstein in 1915, is a theory of gravity that describes how massive objects like stars and planets influence the fabric of spacetime, causing it to curve. This curvature of spacetime dictates how objects move and how they interact gravitationally. In simpler terms, objects with mass cause spacetime to bend, and this bending affects the motion of objects, including light, even if they don't have mass.
