Um, just differentiate the known functions of ##\tau## with respect to ##\tau##?

We don't know. Different interpretations of QM say different things about this.

This question has already been answered: cosmologists so far have paid little or no attention to the theory. Ultimately it's up to the...

I'm not sure what you mean. You say the theory does predict the metric. That is sufficient to predict the specific function.

You do indeed say about Trifonov's theory: But then you go on to state: That description of the universe implies that the scale factor...

In a sense, that's true, but not the way you mean. See further comments below. And in any case, that doesn't change the fact that a...

It's a slice taken out of spacetime, but it has no extent in the fourth spacetime dimension. So it has no spacetime volume. In a model...

A piece of spacetime doesn't have a 3-volume. Here's what you said earlier: In other words, you're saying "Lebesgue volume" of a...

He says "associated with". Why not just "is"? Because actually, no, the position he describes is not Everett's relative state...

This doesn't make sense. Lebesgue mesaure is one function of time. Matter density and radiation density are two different functions of time.

But matter density and radiation density dilute differently as the universe expands (that's why it's even possible for the early...

As I said, I'm not a cosmologist, but I can see at least one obvious flaw in the model you describe: This is not true of our actual...

I'm not a cosmologist. I based my opinion on what I know of cosmologists' reaction to the paper (i.e., basically none), and general...

But his analysis does not do that. An Everett type of explanation makes crucial use of the entanglement between the measuring device (or...

It's a speculative model, which, as far as I can tell, has not gotten any real traction in the cosmology community. So the answer to...
