There is now an emerging theory that a Universe, is a ripened fruit at the bottom of a black hole in another universe. It is a life cycle. IT is sucessful if it can manage, thru the birth pains, to end up with Fundamentals that allow for rich and deep black hole production. IT's wombs. In Many Worlds, a universe could be sterile, born a drone and unable to create the wombs. And another, born in the right conditions, could be quite fecund, indeed.
So, have you ever puzzled over the Flatland story? If we are on a 2D plane with no 3D perception, what would a sphere passing thru it, look like, in 2D?
First, just a dot appears, a Big Bang out of nowhere. Then it inflates practically instantaneously to a small circle. The Inflationary Period. After that near instant switch from a point to a tiny circle, the "circle" of 3D spacetime continues to expand. As the higher dimensional, Baby universe matures in it's passing through, we get to the circumference.
So, the analogy is a Higher Dimension creature born from the mother of all twisted timespace, a Black Hole, and is born into a matrix, the Higgs Field?
As it is pushed out into yet another Higgs Field from the Mother Universe, particles are condensed and are sorted by density. These particle create mass, therefore, and hopefully she can make a womb for herself.
