I respectfully disagree about the need to attach significance to the concepts of time and space. Certainly not all people need to do so, but some certainly should.

No I didn't say that. Perhaps someone else can explain why the Tolman surface brightness test results have been shown to support expansion.

Supposedly in a static universe the appearant area of a distant object and the radiation intensity will both decrease with the square of the distance, yielding a surface brightness that should be independent of distance. Consequently, the fact that the surface brightness is a function of...

Perhaps I am just saying stuff that everbody knows, but expressing it very inefficiently.

Yes, you are right. My distinctions are not very clear, and it does seem that time and distance are very similar, both conceptually irrational and real. Space-time therefore is also so is it not?

We can forget Compton scattering for the time being - fine with me. But distant sources are in fact spread out, as evidenced by the Tolman surface brightness test.

It seems unlikely to me that light could arrive, after billions of years, with all of its directional information intact. By design, the telescopes are filtering out all but the direction-specific wavelengths. Has anyone discussed that on top of inverse square loss there could be another loss...

The word i used was interval, I think. Never used the word integer. I don't have answers about what irrational space means - it's just my layman's term to convey a lack of clarity on the subject.

I suppose the stretching and dimming could be an inherent property of the redshift phenomena, regardless of root cause, but a successful theory would have to show that as you said.

That didn't really answer my question but thanks anyway

by the way - thanks. I checked out the thread that you suggested, and certainly don't want to restart a heated debate that goes nowhere. I withdraw my original comments and label them as "not at all useful" (until such time as someone comes up with a shocking and useful new theory - and then I...

Yes, I agree. And that was my point really - that space could not be less complicated than time.

It seems like human understanding of space can be no clearer than our understanding of time. I still don't understand time. On the one hand it is a discrete interval; but it is also continuous and infinite. All our science is based on an understanding of this time concept and its constructions...

What radiation model is used for understanding the cosmological redgarbage? It seems that neither a planar wave nor a point source would represent what we think we are really observing when looking at distant galaxies or exploding stars. Could the observed redshift be a property of the radiation...

Those are two good points that I was not thinking about! I was actually wondering if there would be a lot lower W/m2 because the frequency is somewhere in the infrared I think (I didn't try to figure it out from the article). Certainly the incident energy must be lower in the evening, relative...
