The universe is simultaneously expanding and contracting...

Like an electromagnetic field. Whether the tiny atom or the larger multiverse, it is simultaneously as finite or without limits. At a certain point, math fails in cosmology. That failure arrives when one can no longer deal in the finite and defined spaces. So one has to look at evidence right before our eyes.
Every atom gives us a clue to the origin of the universe. The way energy functions and it's properties - are the properties of the greater universe.
Names will come and go in cosmology; ideas get recycled and updated and new names get attached to them.
