A Hidden Connection Between Digital Physics, Quantum Mechanics, and Relativity (scrollto.com)

> It is thought to be impossible to do continuous movement in any direction, if having to take place on a discrete lattice..ie a chess board..a pixel universe. The most famous example is Conway’s Game Of Life.

Followed by an animation of Conway's Game of Life, which launches gliders, which proceed to continuously to the bottom right until they exit the scene. If the scene were bigger, the gliders would move until they exited that scene, too, because they move forever in the same direction. So... that didn't prove the point very well, did it?

[Edit: Or was the point that you can't do continuous on a discrete lattice; that is, you can't move 0.1 pixel? Well, yeah, that's kind of trivially true, and also not very interesting.]

No.

It actually isn't. Our universe appears to have equal speed of light in all directions and a full fidelity of directions, the continuum. Both QFT and GR rest on premise that spacetime is a continuum. However, even if it isn't a continuum, there are ways to make it seem as high fidelity as possible. These techniques may be at use in our own very universe, which may indeed be digital voxels. Everyone is always asking for a reason for QM, for the indeterministic randomness - here lies a potential answer.
