What was there before there was a "There" there?
We're a little closer to an answer....
Analysis of microwave radiation in the vast "emptiness" of space suggests that our universe bubbled off a previous universe, and that in that moment our universe already had a set of rules. In other words, the rules of physics that we know didn't just fall into place like sevens on a One-Armed Bandit - they were part of this Universe's original structure.Detailed measurements made by the satellite have shown that the fluctuations in the microwave background are about 10% stronger on one side of the sky than those on the other.
Sean Carroll conceded that this might just be a coincidence, but pointed out that a natural explanation for this discrepancy would be if it represented a structure inherited from our universe's parent.
Isn't that awesome? Our universe could be one of an endless chain of parent and child cosmoses, bubbling and budding off each other in some supra-universal froth.Their model suggests that new universes could be created spontaneously from apparently empty space. From inside the parent universe, the event would be surprisingly unspectacular.
Describing the team's work at a meeting of the American Astronomical Society (AAS) in St Louis, Missouri, co-author Professor Sean Carroll explained that "a universe could form inside this room and we’d never know".
A Big Bang from the inside, but less than a flicker of light from the outside.
Research is ongoing, but this really should be bigger news than it is....
