Black holes 'attracting' light?
I'm puzzled. If light is made up of photons and photons have no mass, how can black holes 'attract' light into themselves - surely gravity only acts on things with mass? I can't see how thinking of light as a wave would help with this either...
Sorry if the answer is very simple - I think I must be missing something obvious but it's annoying me!
Thanks!
