asked on Alternative explanation for Hubble's Law
When one looks at the huge repertoire of evidence supporting the Big Bang, there really seems no doubt.
But let's take just Hubble's Law for now. A sceptic might argue that perhaps there's some property of space which causes the frequency of light to change as a function of distance that it propagates. So the further the distance, the greater the shift, and so the greater the measured velocity.
I've read of such an argument being made before, and I'm wondering if there are any grounds to dismiss it? Can we be sure that this measured red-shift is due to the Doppler effect?
Thank you

I like your openmindedness about this subject. What most people fail to realize is that a phenomenon occurs in nature and we try to describe it We make all kinds of fancy models. Then, we get carried away with our fancy models. And, we believe them more than what we were looking at in the first place.
It is always a good idea to go back to the beginning and take a fresh look.
I wonder sometimes why the red-shift increases the farther away. It should be steady unless they are accelerating. What could that be? Sometime pushing or pull them away? What force could that be?

ozo>Does your alternative property make any predictions that we may be able to use to distinguish the explinations?
Perhaps. By applying Hubble's law to the equation of red shift, my back-of-the-envelope calculation (not literally, I'm out of envelopes) suggests that Voyager 1, at a distance of about 108 AU, would produce a red shift of about z=1.2e-13. Could we measure this?

If everything were moving at the same velocity away from us, then that would place us at the centre of the expansion..
