This is how Ed Fredkin explained the nature of energy to me: There are two kinds of energy. Momentum is information disparity in space, and matter is information disparity in time. I don't even know if it is true, but it is a gem of deepest insight, if you can see it.

(In Fredkin's cosmology, space is a lattice that stores information at its nodes, and time results from the succession of states of that lattice. Mass is a periodic in-place fluctuation, due to a disparity to the adjacent states, and momentum is a translational fluctuation.)

Most likely ruled out (or heavily constrained) by bounds on space time defects

Do you suggest that space time is too messy to support his deterministic automata dynamics, or more messy than suggested by his model, or not messy enough?

I mean that it is exceedingly hard to get relativity emerge healthy from these types of models

Most of them violate lorentz invariance too much to stay in the game

The trick is to understand how rate of change and shape of an observer get deformed depending on the observer's translation. Lorentz invariance seems to result from the observer's ignorance about its own deformation.

This sounds weird. Whats the shape of an electron or photon?

When most physicists talk about observers with respect to relativity or QM its not about perception

In classical physics, observation is about knowledge, in GR it is about trajectory, in QM, about measurement. From the computational perspective, observation is about the patterns observed by a computational system now, and the patterns these allow to predict for the future.
