Also I am equally ballanced between a and b at this point.

that you are questioning if there is expansion? To make it possible it does require that space from trillions of years in the past has expanded the wavelength (or sine wave like part) so that we see it as longer now that when it was first emitted.

Now first I look at alternatives and so this is not the mainstream expanding space answer. In order to have light redshift over trillions of years without expansion means that light travelled faster back at the time it was emitted than it can now. So what redshift is in that case is like a change in pitch down a notch. The reason the idea clashes with accepted science is that it requires light to have changed speed over time.

Second time could have changed over that time frame to slow the rate of passage of light and current science is even more opposed to that concept.

Space could be getting dragged as one would expect near an event horizon but that then defines dark energy as all pervasive and the idea there would be that we are like some part of a smaller Mandelbrot set on a larger dynamic attached membrane and that membrane is not subject to the laws of relativity. It is a third option, one I have not gone into because it redefines dark energy not as a force like an anti-gravity and subject to the speed of light. It then defines dark energy as an entire and unseen membrane changing size evenly and fully attached to our universe.

Fourth is the option I have looked at where the vacuum of space is a false positive and that the pressure of the universe has changed showing a slight and uniform increase and that causes light to redshift. Much like the extra water pressure makes the high pitch detection ping sent out from a boat to find a submarine sound so much lower in pitch to the crew within the submarine.

There may well be other ways like temperature which would have changed since the big bang. Unless you have a favoured position it gets a bit hard to step forwards because in some ways these ideas are at odds with some of the other ideas and not just with mainstream science, (which is probably why mainstream science stays very firmly with an idea that is very hard to prove wrong).

I hope that helps, cheers.
