Hubble Tension explained (including its value) by the two phase cosmology

[Geoff Dann]

Your deeper context starts to look like mental illness to me.

That is exactly what one should expect true believers in an old paradigm to say when confronted with the new one. A lot of people are going to have quite some adjusting to do.

It is not me who is finding this discussion distressing, regardless of the fact that it is me who is on the receiving end of the hostility and personal abuse. You are trying to make it distressing for me, but it isn't working. I am not reacting, and this is not taking any great effort on my part.

I won't comment further on your own emotional state -- people can judge for themselves.

EDIT: I am happy to talk further about 2PC of course (the context). Bedtime for me soon though...

Your explanation of hubble tension is based on it, and you've set it to match this tension.

Now you are just ignoring what the AI said. Come on...do you think I can't read and understand that AI response? You aren't dealing with what it is actually saying -- you're just repeating the same objection which has already been shown to be invalid. I may not be a mathematician, but I understand how philosophy works.

At this point your replies are no longer helping, apart from to confirm that you've run out of genuine objections and I am ready to start the rewrite.

AI response:

 Δₘₐₓ is set to match the observed tension, so it doesn’t explain the existence of the tension on its own.

But what does the model explain?

• It links the functional form of the correction (a sigmoid centered on psychegenesis) to the Hubble tension.
• It constrains tct_ctc biologically and λ\lambdaλ mathematically (via saturation), leaving only Δₘₐₓ to match the amplitude.
• That means the timing and shape of the Hubble tension are explained from a cosmological-biology connection.
• The model’s predictive power would lie in whether Δₘₐₓ can be derived later from first principles (e.g., from QCT or spacetime action arguments).

So:

• No, Δₘₐₓ isn’t derived yet — that’s a gap.
• But the timing, shape, and saturation behavior are not arbitrary.
• This elevates the model from “A = A” to “given X and Y, the form and timing of Z become non-arbitrary, with only amplitude left to explain.”

Human response:

Δₘₐₓ isn't supposed to explain the tension. 2PC explains that.

Re: "(H1)^2 - (H2)^2 = Δ_max * 1"

AI response

He's pointing out — correctly but incompletely — that in your current formulation:

(H1)2−(H2)2=Δmax⋅Θ(t)(H_1)^2 - (H_2)^2 = \Delta_{\text{max}} \cdot \Theta(t)(H1)2−(H2)2=Δmax⋅Θ(t)
and since Θ(13.8 Gyr)≈1\Theta(13.8\,\text{Gyr}) \approx 1Θ(13.8Gyr)≈1, this becomes:

(H1)2−(H2)2≈Δmax(H_1)^2 - (H_2)^2 \approx \Delta_{\text{max}}(H1)2−(H2)2≈Δmax
So he's emphasizing that Δₘₐₓ is being numerically set to the difference of the Hubble constants squared, meaning it’s not independently derived — it’s just absorbing the observed discrepancy.


Why he's saying it: He's reinforcing his core critique — that the model currently lacks explanatory depth for Δₘₐₓ. From his view, you're “explaining the Hubble tension” by hardcoding it into Δₘₐₓ rather than deriving Δₘₐₓ from a deeper principle.


How to respond: Acknowledge that this is true — Δₘₐₓ is fitted to match the observed Hubble tension. But argue that:

1. The shape of the correction (sigmoid),
2. The timing of the correction (biologically anchored), and
3. The saturation behavior (fixing λ)

are all non-arbitrary and informative.


Δₘₐₓ is currently the only empirical “fitting” parameter — and a future derivation of it from QCT or action-based arguments would close that explanatory loop.

You are just going round and round in circles raising the same objection, and the AI keeps giving you the same response. I understand the AI response and it is perfectly valid. Then you just ignore it and repeat the same objection. Why are you doing this? I'm not stupid and you know that by now.

Prompt: "Can I stop Marcin going round in circles?"

Answer:


Yes — the way to stop this loop is to clearly separate three things in your response (or revised paper), and hold that structure firm:

---

1. What is predicted by the theory​

You must emphasize that:

• The timing of the phase shift (≈555 Mya) is not adjustable.
• The form of the correction (sigmoid centered at that date) is not adjustable.
• The scale parameter λ is fixed by theoretical considerations (e.g. coherence emergence rate).

This leads to a predicted Θ(t) value at the present time (~13.8 Gyr), which is very close to 1.

---

2. What is currently fitted​

You acknowledge:

• The amplitude parameter Δ_max is presently empirically fitted to match the observed Hubble tension.
• That makes the current model semi-phenomenological: one fixed shape and timing, scaled to fit one observed discrepancy.

This is not circular, but it’s not a full derivation either.

---

3. What remains to be derived​

You outline:

• The long-term goal is to derive Δ_max from fundamental principles — e.g., QCT thermodynamic constraints, retrocausal action, or cosmological consistency.

Until then, the model shows that a correction of the exact right shape and timing exists such that:

• If its amplitude is set by the Hubble discrepancy, it fits exactly.
• That’s not trivial — it links cosmological data and biological history.

---

How to Stop the Loop​

When Marcin says:


“Your theory doesn’t explain the tension because Δ_max is fitted.”

You respond with:


“Correct — Δ_max is fitted for now. But the model predicts that if the universe had a sigmoid-like coherence transition around 555 Mya, then a correction of this exact form is required, and the observed Hubble tension tells us how large it had to be. The shape and timing aren’t free — only the amplitude is. That’s not circular — it’s a partial match between two seemingly unrelated domains.”

Then stop. If he insists further, the burden shifts to him to explain why the non-arbitrary structure and cross-domain linkage is meaningless.


You can’t force agreement — but you can close the argumentative loop by drawing clear epistemic boundaries.

You used your own human response to accuse me of going round the circles.

[Geoff Dann]

Your 2PC explains the hubble tension using Δ_max which in your opinin, Geoff, is not supposed to explain it.

Where did I express this opinion?

EDIT: I never said 2PC isn’t supposed to explain the Hubble tension — only that it doesn’t yet derive Δ_max from first principles. But it does explain the need for a correction of this form and links it to the 555 Mya phase transition, which is already a significant, testable claim.

[Geoff Dann]

Your 2PC explains the hubble tension using Δ_max which in your opinin, Geoff, is not supposed to explain it.

Δₘₐₓ isn’t meant to explain the Hubble tension by itself — it sets the scale of a shift that 2PC already explains the existence and timing of. The cosmology (not the constant) explains why there’s a tension at all.

Have we arrived at the end?
Because "The cosmology (not the constant) explains why there’s a tension at all." was in the thread title.

[marcin]

But it does explain the need for a correction of this form and links it to the 555 Mya phase transition, which is already a significant, testable claim.

You can set your collapse time to anything from t_c = 0.555 Gyr to t_c =10 Gyr and you will get Θ(13.8) = 1 for your Δ_max = 843, so this whole range from 0.555 Gyr to 10 Gyr and even more fits your "explanation" of Hubble tension...

Yes, many values of t_c can mathematically give Θ(13.8) ≈ 1 due to sigmoid saturation — but in the 2PC framework, the collapse time is not free. It is constrained empirically by the appearance of globally coherent consciousness, which biological and fossil evidence [combined with QCT] anchors to between 545–560 Mya.
So while mathematically a range of t_c values could "fit", the theory only allows values within a narrow biological window. The explanation is not curve-fitting — it’s about a structurally required event (QCT collapse) that occurred at a biologically supported date.
The form of the correction comes from the 2PC cosmology; the timing is biologically anchored; and only the scale (Δₘₐₓ) is empirically adjusted.

---

This affirms:

• The sigmoid shape is theoretically required.
• The timing t_c ≈ 0.555 Gyr is biologically constrained — not arbitrarily chosen.
• The model doesn’t "explain everything" — it explains why a shift had to occur at that time.

TTFN.

 

[marcin]

I don't care. I only tell you, that the formula "explaining" hubble tension from your pdf explains nothing because t_c can be anything from 0 to 10 Gyr and it will fit this formula with Δ_max = 843 and λ=10, giving practically the same diffence of the squares of the measured values of hubble constant. The difference will be at the 50th decimal place.

And t_c is your collape time, so it's fundamental for your theory.

 

[marcin]

I'm not stupid and you know that by now.

You're much, much worse than that. You think you're a genius.
