Good question, and I must admit I don't really have a good answer, other than the fact that not all the scattering happens near the source. Of course now you are going to say, "then why aren't they even blurrier?" Aren't far away objects blurrier than close ones? Perhaps this isn't the whole cause of the red shift, but it must be a contributing factor. > >Harry Regards, R. van Spaandonk Crops, not towns, should be planted on floodplains.

In reply to H LV's message of Wed, 31 Aug 2022 11:04:43 -0400: Hi, 1) This is an interesting idea. 2) Light bounces off particles anyway, regardless of whether or not people believe this causes the red shift. Images *are* blurry to some extent, however, if most of the scattering occurs soon after the light is emitted, then from a great distance the source will appear to be a point source anyway. 3) Most of the scattering does happen locally, because there is a gradient in the density of particles. Greatest near stars, and decreasing into intergalactic space. >When a wave pulse encounters a change in the density of a medium some of >the energy of the pulse is transmitted and some of it is reflected. > >Suppose it is possible for a wave pulse to partially self-reflect by >inducing a local change in the density of the medium as it travels through >it. >If this is possible then the difference between the cosmic microwave >background (CMB) and the Hubble redshift would literally be a function of >perspective. > >The CMB would be the reflected energy from our own local emanations, and >the Hubble red shifted light from a distant galaxy would represent the >energy lost as it is reflected back to the originating galaxy on its >journey to us. > >This would mean the CMB is not an echo of the entire universe as it was in >the past according to the expanding universe hypothesis.
