The Maximum Tension Principle in General Relativity(2002)

Another similar treatise listed a bunch:
Maximum pressure is what you would hypothetically feel on the bottom of your feet if held up against the gravity of a black hole at the even horizon, as-if standing on the surface of a solid plant or on the floor of a spaceship holding position.
Maximum irradiance is the photon density that would turn into a black hole because there’s too much mass/energy per unit volume of space.
Etc, etc…
Essentially, the existence of black holes puts constraints on everything physical. There are no true infinities in the universe!
I’ve never seen a better argument for “we’re living in a simulation” than this. It just feels an awful lot like everything is represented with 128-bit numbers and these extreme are what happens as you approach the maximum representable range…
