Human: Why is light affected by gravity even if it doesn't have mass?

Assistant: 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.

Assistant: 
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. General relativity is a theory of gravitation that describes how massive objects distort the fabric of space-time, causing gravity. In other words, it explains how gravity works as a result of the curvature of space-time caused by the presence of mass and energy. Sure thing! Here is a concise explanation of General Relativity:

General Relativity postulates the existence of so-called *spacetime* which encapsulates both spacial and temporal dimensions in a singular special 4D coordinate system. 

A straight line path (geodesic) in this *spacetime* object corresponds to the path that an object (with no forces acting upon it) would move along. Energy and mass alter the local geometry of spacetime and therefore change how objects move around them. This explains the observed phenomenon of "gravity".
This can be summarized in simpler terms by the saying: "Energy tells spacetime how to curve, spacetime tells energy how to move."

Please keep in mind that this explanation is lacking in terms of scientific and mathematical precision to make this answer more understandable.
