OK, but I understand this is also true if we assume a constant expansion. What changes here when the light experiences "additional expansion" due to the accelerated expansion? Or why does the added expansion due to an accelerated expansion have a more pronounced effect on the luminosity, even...

Hi Chalnoth! Maybe it is obvious if you know the Math behind it (I certainly don't), but to me it again sounds as if you describe the same thing with different words. Isn't "how the rate of expansion has changed since the light was emitted" exactly what you need to know to determine the...

Hi Peter! Thanks for the link! I will fight my way through it. Will take me a while though, I am afraid. So let me try to rephrase my question once again without distances (and still without formulas) : Why does the added expansion that the light experiences on it's way to us have a more...

Thanks for the reply Chalnoth! OK, the relationship is not linear, got it! But still you say that, with accelerated expansion, distant objects at a given redshift are at a greater distance. So it appears to me that the "added" expansion seems to have a bigger effect on the distance (or...

Hello! I have a question regarding the effect of the accelerated expansion of the universe on the Hubble plot (redshift over luminosity (or distance). I understand that for relatively nearby galaxies, this appears to be a linear relationship but that because of the accelerated expansion of the...
