The history of all models is that they are incomplete until someone discovers/stumbles across an entirely new insight that comes from a new breakthrough or from an old tool or analysis.

In reality and for all practical purposes the cosmos is a flowing eternity….of everything.

That may be a tautology, but there’s insight to be had from it nonetheless because you can’t very well buck the cosmos and its nature. And if one contemplates that nature until they thoroughly understand it and can put a word to it and then compares it to the state of whatever is under analysis….it may lead the way out of the problem under discussion and the way home…to where one has always been….and didn’t know it.
