Hello,
I have made a 26 minute video to explain my version of the MUH on my YouTube channel. It's called 'Universe on a T-Shirt AKA How Nothing = Everything' - Meat on the Bones of the Mathematical Universe Hypothesis. Link below:
The hypothesis predicts that:
a) Dark Energy is a warp caused by Entropy information, just like Gravity is a warp caused by Energy information.
b) One dimension of Space is warped by Energy and Entropy information - in the extreme cases forming Black Holes and Cosmic Rips, which each dynamically add a Space dimension, forming 3D space.
c) This 3D Space further warps to an infinite dimensional space, Matter in these higher dimensions would seem like Dark Matter to us, and the fractal structure means the infinte copies make this type of universe most likely, so we are in a typical universe.
