If we are but one of endless universes, like the foam of bubbles...

Expansion occurs within each of these bubbles for a time, and then one tiny bubble expanding next to a neighbor doing the same....with all neighbors around THEM doing the same, 2 of the bubbles suddenly open to each other, and become one larger bubble. Near the point of the time they are coming together, they begin to speed up radically, and then snap and then slow as the larger single bubble wobbles a tiny fraction of time and settles.

We may be at the point shortly before the universe snaps together with another.

Our neighbor is knocking, and we haven't let them in ....yet.
