That so many galaxies once upon a time formed so early once upon a time is [no] fact at all. No once in forever, or just once in a 1-dimenional line-string of cycling, fact! That so many galaxies, and so many other entities, have always formed so early; are always forming so early, and will always form so early, in level of a current and concurrent multiverse of levels, universes to infinity and eternity horizontal and vertical, I state in dispute is a fact! Despite what some people think and would have us believe to the exclusion of anything else -- as being, to them, impossible because we aren't supposed to dispute their premises for their structures built over their [indisputable] premises (built indisputably upon distant mirage sands, that is to say solely here in light and not at all actually distant either in space or time), there is no such thing as closed systems without concurrent open systems. There is no such thing as one world without concurrent many worlds. No such thing as one dimension without many, nor one universe without many. There is no such thing as unity without division, concurrent! And just because they are unobserved in that observed universe at / in scopes -- are unobservable (inertialessly 'fast') universe within and without that observable (inertially 'slow') universe -- does not means they do not exist, period! I say, because there are two or more sides, two or more levels, it means they, the unobserved and unobservable -- more or less ['inertialess'] -- universes must exist and probably do, too, right under the noses of those who continuously without letup naysay the unobserved and unobservable universe, universes, and physics there of! They don't have to be seen to be believed (to be realized). Doctrinaire mediocrity, stone 1-dimensional thinking throughout history and without doubt throughout the future, has been and will always be fought in the streets.
There will always be many coins more than one, even if all of them of a certain type are single-sided 2-dimensional coins (frames) without any rear, any backside, to them to run up, to run down. Only the stereotype, the archetype -- such as my PBB(B)H (collapsed constant) Horizon, aka my Infinite Multiverse Universe Horizon ('Aice In Wonderland', 'Through the Looking Glass' (into the 'Mirror's Window)), an ['inertialess'] Quantum Mechanics-like picture raised to the macro-macro-cosmic from the micro-micro-cosmic and being the 'beyond relativity' both ways) -- will ever be singular as far I'm concerned . . . and probably a few others of mankind, just a few others, to boot, willing to dispute a 1-dimensional universe only . . . willing to dispute an imposition of (a naked singularity of) observed / observable ['inertial'] universe "conventional wisdom" picture only!
