According to our current understanding of black holes and the laws of physics, light emitted from within a black hole cannot reach another universe or dimension.
Black holes are regions of spacetime with extremely strong gravitational forces. The gravitational pull of a black hole is so intense that not even light can escape from it once it crosses a boundary known as the event horizon. Anything that crosses the event horizon, including light, is trapped within the black hole.
Inside a black hole, our understanding of physics breaks down, and our current theories, such as general relativity, are insufficient to describe the conditions. Therefore, it is not possible to make definitive statements about what happens inside a black hole, as our understanding is limited.
Speculating about other universes or dimensions is highly speculative and not grounded in empirical evidence. While some speculative theories, such as certain formulations of string theory or the concept of a multiverse, propose the existence of other universes or dimensions, the interactions between such entities and black holes are currently beyond our scientific knowledge.
In summary, based on our current understanding, light from inside a black hole is unable to reach out to another universe or dimension. The extreme gravitational forces within a black hole prevent anything, including light, from escaping its gravitational pull.
