ELI5: How come photons have no mass (0.000...), don't interact with the higgs field, but are caught by black holes?

Gravity isn't just an attraction between masses. it's also a bending of the fabric of space. So even though a massless photon is traveling in a straight line, gravity's effects redefine what "straight line" means.

In the case of a black hole, if that straight line path takes it past a black hole's event horizon, the path is so bent that it never comes back out.
