A deeper look

This has got to be big news, perhaps our first glimpse behind the cosmic firewall which obscures our view to about 13.5 billion light years. Prior to that point photons were scattered by dissociated protons and electrons, rendering the universe effectively opaque and once the universe cooled enough, the electromagnetic force was able to overcome the energy levels and hold electrons and protons together as hydrogen, allowing the universe to become transparent.
This makes it impossible to see the earliest moments of the universe directly, but this week it appear the first crack in the cosmic veil of secrecy has  appeared. It comes in the form of polarity shifts that are observable as altered polarity in the CMB radiation. Theoretical work suggested that gravity wave from the earliest moments of the universe could affect the polarity of light that form the Cosmic Microwave Background (CMB) radiation.
Observers in Antarctica, have seen twists in the CMB that seem to approximate some predictions of this earlier theoretical work.
This is also the first time we have seen evidence of the gravity waves that were predicted by Einstein. It may also be a big step toward a grand unified field theory for explaining the for fundamental forces of nature, the strong nuclear force, the weak nuclear force, electromagnetic force, and the wascally wabbit of them all, gravity.
