Why has there been no progress in physics since 1973?

The twentieth century was a truly exciting time in physics. From 1905 to 1973, we made extraordinary progress probing the mysteries of the universe. Then, in 1973, this extraordinary progress... stopped. Why?

How to find causally invariant rules

Causal invariance is a crucial characteristic for any rule of Wolfram Physics. Given that not _every_ rule of Wolfram Physics is causally invariant, I asked Jonathan Gorard how we find the ones that _are_.

How to knit the universe

Some of rules of Wolfram Physics seem to fabricate space itself in much the same way as knitting needles might fabricate a blanket... and if you think that knitting is a far-fetched analogy, just wait until you see my animations!

What is physics? the how and the why

I pick up a stone. I hold it in my hand, my palm over the stone, my fingers curled underneath. I let go. The stone falls. Why? This one-word question takes us to the heart of what physics is. And, perhaps more importantly, what physics isn't.

How to measure the dimensionality of the universe

Beware invisible things

As I explore Wolfram Physics, I'm aware of certain invisible things that we believe in now, but we're going to have to let go, if Stephen Wolfram is right. And I'm also aware of the temptation to replace this old set of invisible things with a new set of invisible things. Here's why we'd do well to resist.

Where to apply Wolfram's rules?

The question of where to apply Wolfram's rules is not as easily answered as you might think. This seemingly straightforward question will take us into the philosophy of time, causality, consciousness, contingency and determinism. And it'll lead us towards some of the most important concepts in Wolfram Physics: the multiway graph, branchial space and causal invariance.

Hypergraphs are everywhere

Wolfram Physics models the universe as a hypergraph. Maybe I'm just seeing things, but it seems to me that hypergraphs are everywhere: physics, chemistry, biology, neurology, ecology, sociology, technology. What I want to know is: Why? Why are hypergraphs everywhere?
