We have no way of knowing if the image of a distant galaxy is blurred or not due to the fact that we can obtain no image which does not contain the intervening particles.

Are you quite sure of that, Bill? Isn't the resolution of the HST and other modern photon receivers - able to 'see' billions of parsecs - sufficient to rule out scattering as the cause of the measured redshift? Have you taken a look at the Hubble Ultra-Deep Field image?

Just for the record, as you probably know, it has been a matter of controversy:

BTW, do you still think we have no way of knowing if the image of a distant galaxy is blurred or not, despite the HUDF images? Surely, if blurring has occurred during the several billion lt yr journey, then it must be of an extremely small order. don't you agree?
