The relativity cause for redshift
It occurs to me that if space time can be considered as a rectangle moving thru space such that the [size=height] of the rectangle is one dimension and the [size=time] it is moving is another dimension and multiplied they give an [size=area] which is the same for all observers, (in different frames of reference) even though the observers disagree on the height and time measurements, then why couldn’t this account for the decreasing energy (redshift) from galaxies further and further away?
The analogy is that even though space (area) is the same everywhere, we on earth measure distances more and more inaccurately as the time it takes for the light to reach us increases with the distance. You could say each light year is a frame of reference. Light is traveling so far that it’s frame of reference (relative to ours) is very different and is constantly changing in a negative fashion relative to ours, thus apparently decreasing its frequency.
Or, light travels at a constant speed but time is relative to the distance traveled and is not constant from our perspective?

Can anyone refute this or help me clarify the concept.
I am not a physicist.

Welcome to the board,
I was hoping someone else would answer this as I not an expert in relativity!!!
However, the problem I see is that there are a whole lot of redshifts z = 0.3 etc and these are not relativistic.
z = v/c and my understanding is that relativistic effects only occur when one is close to 'c' (0.9c?)
So you would need a separate theory for these.
Cheers,

But, the light travelling from the distant galaxy (assuming no interaction w H) would be at the SOL and that is relativistic!
Even with your theory the light travelling between H encounters is also relativiistic.
Second idea:
I find Arp's new photon depostions (thru a white hole) idea as a very good one and would explain redshift due to age and not distance, but your theory is still applicable even if he is correct. You two must have discussed this??

Nah! speed of light is speed of light.
It gets slower cos it is absorbed and re-emitted by electrons.
It travels at the speed of light between electrons but because it is delayed on interaction with electrons the AVERAGE speed is less
