In a recent article in ScienceNews, Ron Cowen states:
(quote) Hidden in the peaks and valleys imprinted on the cosmic microwave background — the radiation leftover from the Big Bang — is a wealth of information not only about the early universe but the distribution of matter throughout the cosmos. (endquote)
The CMB photons (on their way to Earth) must collide with many, many particles of gas, dust, etc. which must change their direction of travel a little bit from each collision. I would think that by the time they reach us, they are quite a bit out-of-line with the spot on the CMB from which they started. In other words, they are being scattered like a piece of sand-blasted plate glass diffuses to a flashlight beam.
Is it possible that the CMBR is not nearly as uniform as it appears to us here on Earth?
