If true, the rapid engorgement would solve paradoxes like why the heavens look uniform from pole to pole and not like a jagged, warped mess. The enormous ballooning would iron out all the wrinkles and irregularities. Those particles were not missing, but would be diluted beyond detection, like spit in the ocean.
This bit in the BBC article in particular is the most exciting part to me:
But by associating gravitational waves with an epoch when quantum effects were so dominant, scientists are improving their prospects of one day pulling the fourth force - gravity itself - into a Theory of Everything.
If this holds up I can't even imagine what happens next. I hope that this and the other things like the relaunch of Cosmos gets people excited about science and space. I guess this works towards confirming the multiverse theory, this once again shows observation following theory.
fireballs619 first brought up the potential of this discovery here.
