Question

How can gravity attract light even if light i.e photon does not have any mass

Answer 1

gravity of earth attract the ray of light.
but it could not attract due to speed of light.

Answer 2

Well, what Einstein said is this.

Gravitational force does not kust occur out of nowhere.

It happens because the space bends around objects having mass. Kind of like how a rubber sheet would bend due to putting a mass on it.

This bending leads to objects getting attracted towards the fold, like a marble falling into the little pit created by the mass on the rubber sheet.

This is how gravitational force arises.

Also, due to this space-bending, light bends when it passes through this space. However, to us it looks like gravity is causing it to bend.
