- In math and in physics the concept of infinity always leads to indefinition, like something that cant actualy exists, as an impossibility a point cant be never reached, instead it get closer and closer.
For example, the einsteins formula wich, describes the speed of light as the limit of velocity to anything, becouse otherwise its mass would be infinity.
Similarly for the black hole wich acts like pushing the speed of light beyond that limit, what is impossible, makes me believe that inside the horizon event of the black hole, it is an empty place and all the things, even light only gets closer and closer to it, but never crosses it, making the inside of the black hole a completly empty place(4 votos)
