Because the B-modes represent the END of a splitting Fractal Black Hole Big Bang nucleus (singularity) inflation process and Black holes heve electric potential!!! creating Alven and Birkeland currents.
So, the Big bang was the splitting and evaporation of the big crunch black hole ( all universal 10^90 particles closely packed inside) into what I call a black hole splitting fractal inflation creating the Lyman Alpha forest structure. What we observe in the B-Modes of the BICEP 2 image should be the END of the Fractal splitting black hole inflation process at the rim of our own Universal bubble and as part of the super symmetric navel cord multiverse.

Quote: “It turns out that the physical process by which inflation generated these gravitational waves is the same process (discovered by Stephen Hawking) by which black holes evaporate. Whenever there’s an event horizon, quantum fluctuations cause it to emits radiation. For an evaporating hole, you look at its horizon from the outside; in our cosmos, we look at the horizon (basically the region from beyond which light can’t reach us) from the inside. Until today, there was no experimental evidence for Hawking’s prediction – but now there is! :-)”
