“Space is big. You just won’t believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.” – Douglas Adams, The Hitchhiker’s Guide to the Galaxy
In the previous two parts I discussed two ideas:
That the universe is finite.
That any computable mathematical structure exists in the same sense as our universe exists.
I would now like to suggest the general form of structure our universe takes: that of a network or graph. I’ll be considering a network to be a finite number of points, some of which are connected and some are not. That’s it. For example:
Clunky graphics I know, but I’m working on it. Continue reading

In these posts I want to present a line of reasoning that is an explanation of why this universe exists, and in particular why it started with a Big Bang.
There are a few points to cover so it will require a bit of patience on your part. Along the way I will be attempting to answer three questions in particular:
What do we mean when we say infinity exists?
What do we mean when we say mathematics exists?
What do we mean when we say the universe exists?
A key part of my line of reasoning is the presumption that the universe is finite along the lines of digital physics. To try and persuade you of this I need to first talk about infinity as it is presented in mathematics and this requires me to talk about the axioms of mathematics, where infinity first makes its ugly appearance.

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
