The equations of general relativity predict that when a large enough mass collapses under its own gravity, nothing can stop it. The result is a black hole, a region of space with gravity so strong that not even light can escape from it. It is now believed that nearly every supermassive galaxy, including our own, has a huge black hole at its center.
Since nothing can stop it, the matter that forms as black hole collapses to a point of infinite density called a singularity. The event horizon of a black hole is the region from which nothing, not even light, can escape the pull of its gravity (Figure 5.9).
In quantum realism, black holes represent the bandwidth of space, when all the channels of space are filled. So despite what the equations “predict”, a black hole isn’t a point singularity of infinite density within its event horizon. What stops the matter collapse that produces a black hole is the finite bandwidth of space itself.
If a black hole is space processing at its maximum, adding to it must expand its volume, which is the case. Adding quantum processing requires more nodes of space, as each node in the black hole is already processing at maximum capacity. Recent arguments suggest that black “holes” are in effect black stars, i.e. sources of energy absorption (Barcelo, Liberati, Sonego, & Visser, 2009).
