Geoff Dann replied to the thread Hubble Tension explained (including its value) by the two phase cosmology.Not sure what this has to do with my new proposal for explaining the Hubble tension?
-
Geoff Dann replied to the thread Hubble Tension explained (including its value) by the two phase cosmology.Great question! You're absolutely right to point out that in the expression Θ(t)=11+e−λ(t−tc),\Theta(t) = \frac{1}{1 + e^{-\lambda (t -...

Geoff Dann replied to the thread Hubble Tension explained (including its value) by the two phase cosmology.Actually....I just asked the AI, and the problem is actually my hamfisted description, not the AI's model.
-
Geoff Dann replied to the thread Hubble Tension explained (including its value) by the two phase cosmology.For the record, I believe the underlying idea is correct. But the implementation was sloppy and rushed.
