In general relativity, gravity affects anything with **energy**. While light doesn’t have mass, it still has energy, and so experiences gravity.

If you visualize gravity as a distortion in spacetime then I think it’s fairly intuitive that it doesn’t matter what the object is. As long as it exists, gravity affects it.
