One of the strangest predictions of general relativity is that if a large body collapses under its own gravity, nothing can stop it becoming a black hole, a region of space with gravity so strong that even light can’t escape. Astronomers have discovered that nearly every super-massive galaxy, including our own, has a black hole at its center.
Physics has no force to stop this collapse, so a black hole is considered to be a point of infinite mass density, called a singularity, surrounded by an event horizon that is the region where light can’t escape its gravity (Figure 5.11). This is based on the equations but in most sciences, an equation that gives an infinity is an error not a fact.
Processing models can’t have infinities because they can’t be computed, so in this model, matter can’t become infinitely dense because space can’t become infinitely small. Space, like a screen, has a pixel limit, and each pixel has a finite bandwidth.
A black hole then isn’t a singularity but a region of space that is at maximum capacity, so it can take no more. Just as the finite transfer rate of network limits the speed of light, its a finite capacity limits the density of mass in a black hole. What stops the collapse of a black hole isn’t a force, but the bandwidth of space itself.
Black holes then expand as they acquire matter because more space is needed to handle it. A black hole’s Schwarzschild radius is linearly proportional to its mass, but if that mass was at a point, its effect would decrease as an inverse square like gravity.
Instead of a singularity of infinite density, a black hole is a volume of space at maximum capacity. Instead of radiating light, it absorbs it, so black holes are in effect dark stars that absorb energy (Barcelo et al., 2009). Sagittarius A*, the center of our galaxy, isn’t a hole at all, but a super-massive dark star with a halo of light whose dark matter keeps its stars together. To us as matter, dark matter is destructive, but for the galaxy, it is beneficial.
