Physics, Astronomy & Cosmology / Can WMAP really see primeval radiation?
« on: 19/09/2017 22:09:27 »
According to Big Bang theory, e/m radiation and matter were created pretty much simultaneously, after the Bang. All this stuff moved outward from the center of expansion, eventually coalescing into our universe.
Matter necessarily moved slower than radiation.
How can we observe any of this radiation from a planet composed of matter? The e/m radiation must have moved outward from the same smallish area of space much faster than the configurations of matter we use to observe it, such as the WMAP observing instrument.
If you send a beam of light from earth out into deep space, you cannot see it. The best you can do is see reflections of some photons bouncing off dust. How can we possibly see any form of radiation that was generated at, or nearly at, the same time as the atoms we use to observe it?
At best, WMAP can only be observing radiation reflected from matter. What reason might we have to believe that this radiation was generated at the B.Bang, when theory implies a subsequent origin?
