At present, our understanding of black holes and the nature of the universe is limited. While black holes are fascinating objects with immense gravitational pull, there is currently no scientific evidence or theoretical framework to suggest that they can be used for inter-universal travel.
Black holes are formed from the collapse of massive stars and have an extremely strong gravitational field from which nothing, not even light, can escape beyond a certain region called the event horizon. While they have been theorized to have various intriguing properties, such as time dilation and the possibility of wormholes, the concept of using black holes for traveling to different universes remains speculative and purely theoretical.
The study of black holes and their behavior is an active field of research, and scientists continue to explore and expand our knowledge of these mysterious objects. It's possible that our understanding may evolve in the future, uncovering new possibilities or providing insights into phenomena that could potentially allow inter-universal travel. However, at this point in time, it remains purely speculative and falls outside the scope of established scientific theories.
