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 it. 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 described as a point of infinite mass density called a singularity surrounded by an event horizon that defines the region where light can’t escape its gravity (Figure 5.11). This is based on the equations but they aren’t theories, so most sciences take an equation that gives an infinity to be an error not a fact.
A processing model can’t have an infinity because it can’t be computed. Matter can’t become infinitely dense because the network of space can’t become infinitely small. It has a pixel limit like a screen and each pixel has a finite bandwidth of how much it can handle, like a cup that is full.
A black hole then isn’t a singularity but a region of space whose points have accepted all the matter they can, and can take no more. Just as the network has a finite transfer rate that limits the speed of light, it has a finite capacity that limits the density of mass in a black hole. What then stops the collapse of a black hole isn’t a force but the bandwidth of space itself.
It follows that black holes expand as they acquire matter because more space is needed to handle it, so a black hole’s Schwarzschild radius is linearly proportional to its mass. In contrast, if that mass added to a point singularity, its effect should decrease as an inverse square, like gravity.
A black hole then isn’t a singularity of infinite density, but a volume of space at maximum capacity with no infinities. 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 that generates the dark matter needed to keep its stars together. To us as matter, dark matter is destructive, but for the galaxy, it is beneficial.
