I assumed that this phenomena would look like a blurring of the supernova image, but I am not quite sure. What do you think it will would look like? At what distance or redshift will it begin to be detectable?

The density of the universe can be 10,000 times as dense as one proton/m3 without dark matter. The best way to get an estimate of the density is by measuring effects such as you are chatting about here like scattering over distance. No doubt a some point the column density will will cause so much scattering nothing will be observed beyond the point. It needs to be determined how many protons are needed to make an opaque column and what kind of scattering occurs between here and there. There is data but it is not being looked at in this way.

This remind me of a question:
Suppose that blackhole exist. After an indefinite time a quantum fluctuation or something else transform all the mass to photons. Will the blackhole be destroy? Or the "rest mass" of the photons maintain the blackhole condition?
In this question I am thinking about the BB where all the universe was concentrated in a small space then was a blackhole.

I am curious about something that I hope someone can answer. BBers claim to have seen areas having black holes. What are they seeing in the MM if black holes do not exist? -MV

The questoin of what is seen and what is reported is very interesting and when a preconceived model is used as a filter this is the result. It is too bad nothing in astronomy gets reported before the BB filter is used. And in my opinion MM filters are no better.
