Consider the shortest algorithm that simulates the universe perfectly.
Meaningless, on my metaphysics. Definition is circular—in order to define fundamental you have to already assume that the universe can be simulated “perfectly”, but to define a perfect simulation you’ll need to rely on concepts like “fundamental”, or “external reality”.
Assuming that the way the universe looks changes continuously with these constants, it seems strange to insist that if the changes are so small you can’t notice them they don’t exist.
The assumption is meaningless. It seems strange to me to insist that something “exists”, especially infinities, which are never observable. On our actual known physics we have strict limits on how much information can be contained in a finite amount of space, but even if we didn’t know that you can’t define these concepts in a noncircular manner.
