It’s “always proved right” because it’s based on the electromagnetic observations that our physical existence depends on and resides in. It doesn’t explain as much as measure real phenomenon.
The 3d+time observations of light based on light by creatures and machines made of light doesn’t really see anything that isn’t light (waves or particles).
If the universe was actually a solid crystal of imaginatium, we couldn’t tell.
We distilled 3 dimensions in order to simplify mathematics over time. When things get wonky, we either screw up time or the mathematics, but the wonky universe keeps going.
A 5-axis milling machine balanced on a boat still exists in 3 dimensions, and always produces a 3D part (so far: search “time crystals”).
You’re trying to define the price of the milling machine based on human zoning laws.
