It says in numerous books that radiation dissipates after about a distance of from the Earth to the sun, and also when the scientists sent the radio signal of the Beatles's music into outer space a while ago, that , even though they did that through SETI, or whatever program they did that through, that the signal will dissipate after a certain distance and not reach any aliens. If radiation dissipates and behaves this way, then how is cosmic back ground radiation evidence of the big bang? Are they saying that cosmic back ground radiation is radiation that was somehow able to not dissipate (or be absorbed)?
