Scientists are puzzled by the lack of ultraviolet light in the universe as announced in the July 10, 2014, issue of Astrophysical Journal Letters. When scientists utilized supercomputer simulations to determine the amount of electrically neutral intergalactic hydrogen, it did not match the amount of ultraviolet light in the universe displayed by the Cosmic Origins Spectrograph on the Hubble Space Telescope. In other words, the amount of hydrogen, the source of the light, was five times more than the light detected.
Hydrogen, which makes up about 73% of visible matter in our universe, is mathematically consistent with dark energy, which makes up about 73% of the invisible matter/energy in our universe. Helium, which makes up about 25% of our known universe, is comparable to dark matter, which is estimated to equal about 25% of the unknown universe. This is more than a coincidence. However, nobody knows why the building blocks of the visible universe have similar percentages as the blocks for the invisible universe.
Does the invisible universe interact with the visible universe so as to capture the missing light emissions? In other words, does dark energy or dark matter consume the light from hydrogen emissions? We know that the early universe had few elements other than hydrogen (75%) and helium (25%), but as the universe expanded, more and heavier elements were created so that today, hydrogen has lost about 2% with helium remaining about the same.
Since dark energy is expected to gain rather than lose mass, the early universe may have had a lower percentage of dark energy, perhaps 70%. As hydrogen continues to decrease in its percentage of the visible world, dark energy would continue to increase in its percentage of the invisible world. The light emanating from the hydrogen loss could be disappearing into the dark side, either dark energy or dark matter.
The missing light primarily appears in our nearby cosmos. When scientists examine galaxies that are billions of light years away, the 400 percent discrepancy does not exist. It does not occur in the early universe. What does this tell us? It may be explained by the decay of dark matter becoming dark energy, so that the missing photons cannot be seen in this invisible universe which is generating the extra light.
It makes sense if you view the visible universe as shrinking as evidenced by the loss of visible light, and if you imagine the invisible universe gathering strength, including light, as it pulls the visible universe into its powerful contracting jaws. The lights may be being turned off by the incredible shrinking universe.
