Is Spacetime a Discrete Lattice? - Prof. Sila Beane's Experiment

Click For Summary
SUMMARY

Prof. Sila Beane's experiment utilizes a Quantum Chromodynamics (QCD) Lattice to simulate a portion of the universe, positing that spacetime is a discrete lattice rather than isotropic. By incorporating the Greisen-Zatsepin-Kuzmin (GZK) cutoff point of cosmic rays, the experiment suggests that the angular distribution of high-energy components exhibits cubic symmetry. This finding is presented as evidence supporting the simulation hypothesis, although the validity of the experiment as a true scientific experiment is debated, with some labeling it a calculation instead.

Recently I found an experiment done by Prof. Sila Beane. In this experiment he simulates a tiny porportion of the universe using a QCD Lattice where spacetime is a discrete lattice. He inputs the GZK cutoff point of a cosmic ray into the lattice and what happens is, the result is that the angular distribution of the highest energy components would show cubic symmetry. He then states that this concludes that spacetime is a lattice and not isotropic, he says this is evidence for the simulation hypothesis, but that's not the point, is the fact that spacetime is a discrete lattice true?

I kind of object to the use of the word "experiment" here. This is a calculation. It's validity I can't comment on.

A question more appropriate for a physics forum is the following: Can spacetime be successfully modeled as a discrete lattice? Which translates to: Does the behavior of the model match the behavior of Nature?

I don't see how a single video could answer that question when it takes years of study to understand how the current model of spacetime, as a continuum, answers it.
