In principle,nothing that enters a black gap can leave the black gap. This has considerably complicated the study of these mysterious bodies, which generations of physicists have debated since 1916, or when their existence was hypothesized as a direct consequence of Einstein's Theory of Relativity. There is,however, some consensus in the scientific community regarding black gap entropy—a degree of the inner disorder of a physical system—because its absence would violate the second law of thermodynamics. In particular, or Jacob Bekenstein and Stephen Hawking have suggested that the entropy of a black gap is proportional to its area,rather than its volume, as would be more intuitive. This assumption also gives rise to the "holography" speculation of black holes, or which (very roughly) suggests that what appears to be three-dimensional might,in fact, be an image projected onto a distant two-dimensional cosmic horizon, or just like a hologram,which, despite being a two-dimensional image, or appears to be three-dimensional.
