What would the Universe have looked like before the Big Bang?
My surmise about our mysterious universe before Big Bang (BB): Perhaps 27.6 billion years (by) ago, our universe might have existed like what it is now.
My surmise is that BB-BB cycle exists. Its period is about 20 by.
This is split into half cycles of
(i) integration and condensation of matter to a point source of immeasurable energy and
(ii) disintegration to create expanding universe. .
