Hello, Peter. Nice to see you here again. What happened to our discussion in the other thread? (Dark energy Dark matter)

Err, because this has nothing at all to do with the accelerated expansion. I know you think otherwise - but in contrast to standard physics, you have not supported that assertion in any way so far.

There is no duality in the form in which you propose it.

Show your math. Don't forget to include the energy and angular momentum contained in the sun, and in the interplanetary gas etc.

No, that's a non sequitur.
Again: show your math.

Show your math: how does duality predict an accelerated expansion?

Well, what about showing first,
quantitatively, that your "duality" exists and can account for the acceleration?

If you think otherwise: provide evidence that it does. I. e.: show your math.

Wrong.
The prediction from GR for a
totally homogeneous universe is that it either expands or contracts. However, the prediction from GR for a universe with
density fluctuations is that even if the universe on the whole expands, these fluctuations will "contract" (on smaller scales).
In the pop-science literature, you will almost always find only the first prediction. Suggestion: try reading some real scientific papers (or at least a textbook) on a theory before attacking it.
