How to validate a simulation?
There's a numerical validation (e.g. energy/mass/momentum conservation, div(B) condition etc), but even when this is passed, there must be a validation against available observable.
A mandatory step, done in any simulation, is the production of observable-like quantities - either images or catalogs of sources.

This collection of frames show the many ways in which the same cosmic volume may look like

Posting some old art. Here's a 2D-style short made with &

The entire scene is with physics and each frame individually hand drawn.

@NicVdSijpe The Fulton fish is a great application indeed! Typically, though, I give them data (and talk about the supply and the demand for ice-cream, last year rainfall (cows & milk), current temperature, etc). Then I move to Quarter of Birth in the spirit of "From Supply and Demand to Natural Experiments" 😀

Space is to our what numbers are to the in any computer. Matter moving through space can simply be seen as operations happening on the . If is moving at say 1,000 miles per second, then 1,000 miles worth of space is being transformed by a , or operated upon every second. If there were some hardware running the simulation called “space” of which matter, energy, you, me, everything is a part, then one telltale sign of the artifact of the hardware within the simulated reality “space” would be a maximum limit on the container size for space on which one operation can be performed. Such a would appear in our universe as a .
