If light has no rest mass, why does gravity affect it?

At first, this sounds like a contradiction.

We often think of gravity as a force that pulls objects with mass. But Einstein’s theory of general relativity gives us a completely different picture.

Gravity isn’t simply a tug on massive objects—it’s the curvature of spacetime.
Massive objects like stars and black holes distort the geometry of spacetime around them. Light travels through that curved spacetime, so its path can bend even though photons have zero rest mass.

This effect is called gravitational lensing, and astronomers observe it across the universe.

So when light passes near a massive galaxy cluster or black hole, it can follow a curved path.

The surprising part?

Gravity doesn't need to “grab” light like a hand pulling an object.

It changes the spacetime through which light travels.
