According to our current understanding of physics, it is not possible to transmit any information or signals from beyond the event horizon of a black hole. The event horizon is the boundary beyond which nothing, including light, can escape the gravitational pull of the black hole. It is a region of space where the gravitational field is so strong that the escape velocity exceeds the speed of light.
Inside the event horizon, the curvature of spacetime becomes so extreme that all paths lead inevitably toward the singularity at the center of the black hole. Any information or signals emitted inside the event horizon would also be pulled toward the singularity and would not be able to escape.
Furthermore, attempting to approach the event horizon would require surpassing the speed of light, which is currently believed to be impossible according to Einstein's theory of relativity. As a result, any data or information that crosses the event horizon would be inaccessible to observers outside the black hole.
It's worth noting that our understanding of black holes is based on general relativity, and there are ongoing efforts to reconcile general relativity with quantum mechanics to develop a complete theory of gravity. However, until a comprehensive theory that incorporates both quantum mechanics and gravity is established, the limitations on transmitting data from beyond the event horizon remain in place.
