Cooling universe after the hot big bang.
String theory zillions of solutions !
String landscape is Different vacua
Inflating like crazy!
with external inflation, then: the multiverse !!
Perhaps our universe is a speck of nothingness in the multiverse.
Negative energy vacuum. Big Crunch
Are we a tiny part of the vast multiverse. if so:
Then it is the modern Copernican revolution.

In contrast with Nima Arkani Hamed however, Quantum FFF Theory says:
Big Bang is the explosion of the Cool Super Symmetric (SuSy) Big Bang dark matter black hole, only heating up by plasma creation ONLY around big bang dark matter black hole splinters and star/Galaxy formation between Herbig Haro dual black holes ( the dual hotspots).
String theory has restricted particle form solutions but because of SuSy entanglement between all quanta the SuSy multiverse bubbles (probably only 8 or 12) we should count zillions of choice solutions for collapsing the wavefunction. see: multiple entangled pinball machines see below.
