From Planck quantum-small, to cosmic large,i imagine Energy fluctuations scale all over the spectrum.
The largest one, must be the entire Universe; as if where the BigBang has reached so far.
(93bilion lightyears.https://en.wikipedia.org/wiki/Observable_universe)
Around that sphere where light has boldly shone (and no light has shone before it)
is where Time-Space ends & extends,
reaching into NoThing, and 'inverts' it into space like formatting a harddisk
hm... that's like dark matter eating dark energy, or the other way around ;-)
i find it really hard to imagine a universe that didn't come 'from NoThing, in the middle of nowhere'...
This is precisely the sort
of thing I love :)
