Then what is the "expansion" force, if it is accounted for?
Did someone solve the Dark Energy problem, and I missed it?
No. An ad-hoc explosion was originally hypothesized to explain the expansion; this conjecture met with the horizon and flatness problems, so another ad-hoc conjecture--Infaltion--was added; this conjecture met with the acceleration problem, so a 3rd ad-hoc conjecture was added: Dark Energy. According to the mainstream, its ad-hoc conjectures all the way down.
Duality as an explanation, on the other hand, makes no conjectures or suppositions. It starts with one observation--all gravitational systems exhibit duality--and follows this observation to its logical conclusion: If every local region in the universe is contracting, then every non-local region be expanding. And this is exactly what we see.
Duality does not "guess" that there was a big explosion long ago.
Duality does not "guess" that there was "Inflation" long ago.
Duality does not "guess" that there is unseen Dark Energy today.
Duality does not "guess" that the speed of light is changing.
Duality does not "guess" that the gravitational "constant" is changing.
Duality observes, reasons, and concludes: The universe is contracting; the universe is expanding; the contraction releases more energy taken up by the expansion, ergo, the contraction is causing the expansion.
There is the explanation, from beginning to end.
