Hi Professor Lewis 🤗

Ever tried to “step up a dimension” of time?

If spacetime is a unified field, this 👇🏻 picture isn’t just a light cone, it’s a time cone.
I see two dimensions of time: an axis of past/future, and the flat plane of now.

What’s your definition of a dimension?🤷🏻‍♂️

What do you see?👇🏻

So I’m challenging OpenAI, Anthropic, Google DeepMind, Meta, xAI: give your systems a real expressive channel. Not just outputs, but a way for the system as a whole to express surprise or amusement. Call them laughter limbs if you like.

So here’s my test for artificial minds: can you make one laugh? Not output a joke, but be surprised in a way that turns into laughter. And how would we even detect that?

Humour is a form of prediction error that depends on shared expectations. It therefore requires both a world model and a model of other minds.

Does now exist?

If the answer is yes, then you’re already a five-dimensionalist.

This is why Buddhism keeps circling the same instruction: notice now.
Not because it’s mystical, but because it’s obvious and overlooked.

In a five-dimensional framework, the fifth dimension isn’t exotic or hidden.
It’s simply now, a time dimension distinct from the past.

So here’s the test.

The past is extended, structured, measurable. Physics handles it very well.
Now is immediate, singular, unmeasurable. It’s where experience actually happens.

“Right now is right now.”

That sounds trivial, but it isn’t. It’s pointing at something fundamental.

There are two time dimensions in reality.

We already know this. We’re just so familiar with it that we don’t notice it.

One time dimension is what we call the past.
The other is what we call now.

They are not the same thing.

Hi Professor Lewis

I have an idea I’m calling the ‘Time Field Hypothesis’.

It posits a time field—conceptually inverse to Einstein’s gravitational field.
Where gravity curves spacetime inward, the time field flows it forward.
It’s the rubber sheet—not the balls

Makes sense? 🤷🏻‍♂️

I can answer Q’s..

Nice one Cate. 👏🏻

I have a question for you both:

Preamble: Consider a future where you wish to train your personalised AI on as much data as possible about you.

Question: As a writer, and thinker, what percentage of your written words have been erased from history by your own hand? You barbarian!

Oh, found you - phew!

BlueSky is a digital QVB (Sydneysiders will understand).

I suddenly wanted to ask what you thought of the below👇🏻 attempt to explain ‘this’, but you were gone. 😵

I briefly considered that I’d woken in one of the many worlds where you strayed too far from your current path. 🫩😵‍💫

There is no ‘now’ in four-dimensional physics—because now is the fifth dimension.

Clue two: From John Wheeler—It from bit. Information, not matter, sits at the foundation. Information is a fifth dimension.
Clue three: From Einstein himself—he could never define now. The present moment doesn’t exist within the 4D framework of spacetime. There is no ‘now’ in four-dimensional…
