The GZK Test of Whether We Are In a Simulation

The world of Digital Physics is generally immune from appearing in mainstream media. But some nights ago, during an insomnia induced late night TV viewing, on a mainstream news source (either BBC or Al Jazeera English, can’t remember which) I saw a piece on Are We In a Computer Simulation? And the term Digital Physics was bandied about.

A google search showed activity in various mainstream news websites that appeared to feed off an article at the MIT Technology Review website that you can find here, which talks about an arXiv technical article that you can find here.

It talks about the universe being a regular cubic lattice of points, with an observable effect occurring when light travels parallel to the lines of the lattice, sort of like getting your car tyres stuck in tram tracks.

So what can we make of this? Continue reading

Hello

Hello. This blog is about digital physics (DP), a fringe-but-not-fringe view of the fundamental physics of the universe that considers the physics of the very small to be ultimately discrete – both with respect to distance and time. My aim is to present some readable, understandable commentary on issues around DP for anyone interested and prepared to listen. While I may present some mathematics, I’ll attempt to keep the wordy parts comprehensible on their own.

I also plan to create some simulations (with movies) but alas, I may well be confusing Ambition with Ability. Continue reading
