If light has no mass, then how does it get sucked into the black hole? How is it that it gets trapped in the black hole? Google gave me explanations that weren't too helpful. Can someone actually explain it?

Everything has a mass. Everything has a weight. This includes light.
That is why everything can be pulled into a black hole.
Mass and energy are pretty much the same thing. Photons have mass.
Are you sleeping in physics class?
Edit: Anyway, to explain your question, it's that the pull of gravity is strong enough to pull the light into the black hole, even though light is very fast.
Took the words straight from my mouth.Quote:

This might help some more:

I suck at physics, but get familiar with the concept of mass-energy. And photons aren't really massive. You can't crash two photons together.
Or maybe you can, and the effect is so minute that you don't notice.Quote:

but suction can pull anything in if great enough.
I don't know about that, but when photons collide, which has been evidenced to happen, there is no real way to explain it other than with virtual particles. I need to brush up on this before my finals. Shit.
^ ^ good luck.
Thank you. If physics wasn't so damn abstract, maybe I could stand a chance.
Am I the only one that giggled after reading the thread title?
Light photons have energy and duly has mass
E=mc^2 (mass times speed of light squared)
And despite traveling at 300000000 meters per second, the gravitational pull is so strong that it cannot pass by the black hole before falling too deep into it's gravity well.
if you pass the event horizon light cannot escape, NOTHING can escape, except for laurence fishburne.
