Couldn’t you keep stuffing more and more energy and get a bigger black hole?
I guess. But it wouldn't be light with a wave length anymore. It would be a black hole.
Also would such a blackhole move at the speed of light?
That's an interesting thought. I don't think so. Once you get the black hole it should gain mass. But that's really hitting the limit of my physics knowledge.
Well ... take you're upvote. Now go burn in hell.
