You could be right, it’s a while since I thought about it.

The scalar field gives one contribution to the overall geometry, and the energy-momentum tensor gives another. Originally Posted by Noa Drake As we observe that matter is distributed diversely over the universe, this leads then to negative and positive areas expressed as local scalar potential energy density, right ? Yes, this is essentially how I understand their proposal. Not all carbonates decompose easily and I couldn’t remember if this was one of them hence my question in post #3. Just as an informative note :I came across this article, and the corresponding paper from 2012:GRAVITATIONAL FIELD EQUATIONS ANDTHEORY OF DARK MATTER AND DARK ENERGY(TIAN MA AND SHOUHONG WANG)”A pair of mathematicians — one from Indiana University and the other from Sichuan University in China — have proposed a unified theory of dark matter and dark energy that alters Einstein’s equations describing the fundamentals of gravity”Link article :http://www.sciencedaily.com/releases/2012/09/120906092059.htmLink paper : http://arxiv.org/pdf/1206.5078.pdf I’m not sure, but are they not aiming to install this as the cause of the fundamental forces, instead of being a fifth force ? No, they postulate a specific form of coupling of the scalar field to the energy-momentum tensor field; this is equivalent to a new fundamental interaction. We successfully did the drying of acetone using Potassium carbonate and the results were fine.

This seems to me more or less exactly what standard cosmology suggests – you start with a hot, dense, very homogeneous and uniform state,...
