No, the images CMBR of WMAP, aren’t visible lights, dad.
Calling CMBR “light” is simply wrong.
It is known physics law that over time photons, or EM radiations will lengthen or increase their wavelength towards the red. Hence, the physics terminology for this phenomena is called “Redshift”.
No that is not known, if you are talking about over great time. Besides a wave is time dependent. We see a wave straming in from out of the solar system area and each crest of that wave, so to speak, takes so much time. As for what shifts light out there, that is not known. What is known is what shifts light in the fishbowl! Then science believes and assumes it must be the same thing working out there...for no real reason at all. Right?
EM radiation is moving apparently at the speed of light science claims.
"EM radiation is created when an atomic particle, such as an electron, is
accelerated by an electric field, causing it to
move. The movement produces
oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of
light energy called a photon. Photons travel in harmonic waves at the fastest speed possible in the universe: 186,282 miles per second (299,792,458 meters per second) in a vacuum, also known as the
speed of light. The waves have certain characteristics, given as frequency, wavelength or energy."

So they call it light energy. It still involves time.
The observation of expansion of universe, is indicated by observation of any two distant galaxies moving away from each, the observed lights spectrum, will showed that spectrum will shifted towards the red end of the EM spectrum.
You chose to interpret red shifted light that way, based on realities on earth basically. Hoever, if time and space were not the same out there, the jury is out on what could bend light, or shift it! You should admit you don't know.
But it is very different with CMBR, because what we seeing today, like with WMAP mapping of the universe, the photons decoupled since the universe was 377,000 years old (Recombination Epoch), the CMBR aren’t visible lights, but ancient photons going beyond the red of EM spectrum. What we really observing is Cosmic Microwave Background radiation, not visible lights.
In your religion, yes, of course. Total fantasy! There was no such long ages that existed to start with. You BELIEVE that IF there were, and IF the space and time in the whole universe were uniform, then such and such would have happened. No. No. No. That is religion. You never saw any light 'decoupling' for some 377 thousand...or millions years! Really. Science has been around mere decades in the distant universe observation business.
And the only way you could detect and measure CMBR, if you have some sort of equipments capable of detecting microwave, like radio antenna, such as those big hunker satellite-like dishes used in radio astronomy - the radio telescopes. Or you have some sort of space observatories, such the COBE (Cosmic Background Explorer, launched in 1989), WMAP (2001) or Planck spacecraft (2009), that were specifically design to detect cosmic background radiation, such as the Cosmic Microwave Background.
That equipment is IN the fishbowl if you notice! They detect/observe only HERE. Yes they detect waves like microwaves.
How and why the ways came to exist is not known.
Even the interpretation of what the waves mean and are like in deep space is open for opinion. They assume for example it means stuff id cold way out there.
"Today, the CMB radiation is very cold, only 2.725° above
absolute zero, thus this radiation shines primarily in the microwave portion of the
electromagnetic spectrum,"

But if the waves entering the fishbowl do not really represent what is going on out there, then we need to revisit even such claims!
As I stated earlier, CMBR is dated in the Big Bang timeline, when the universe was approximately 377,000 years old, and CMBR is older than the oldest stars; CMBR, in fact, existed before the first generation of stars, and it is even older than the oldest quasars.
Total religion and fiction and nothing more than a fishbowl based godless attempt to explain the created universe in their own image basically!
And these CMBR didn’t come from any stars (including our Sun), from any galaxies, or from quasars.
Hey, who cares if they came from a night club on the far side of the universe?? The point is that this 'light energy' as the link I posted called it, arrives here in this world or solar system area, where we start to see it IN our time!
