The aim of this note is to connect various elements from current physics to build an alternative model of some of the invisible objects purported to contribute, at least gravitationally, to the observable universe.
The pantheon of inflationary big bang cosmology includes model versions where time began as inflation started. An unresolved issue with basic quantum mechanics in all such models is highlighted that may or may not help with future developments in quantum gravity theory and/or cosmology. Any issues concerning the cause(s) of inflation are separate and take no part in the following discussion.
