Are there any alternative theories/explanations of why light from distant galaxies is redshifted by an amount proportional to the distance away from us, other than the popular universal expansion explanation? Maybe some theory about light losing energy when traveling over such large distances (the further the distance the more energy is lost, the more the redshift)? Or maybe something related to an alternative gravitational theorem which predicts that other mass out there increases the redshift, ...
If no other theories on this, then I suppose there is more evidence for universal expansion than just the observed redshifts? Could someone send me a link or some keywords so that I can read more about that.
Thanks
