The Universe has No Center?
People --- including mankind's "best and brightest" --- who say "everything has a center except the universe" either aren't very serious, aren't very logical, or they think others are not serious or logical...
Every time I watch, for example, a very serious person like Neil De Grass Tyson using the Earth to explain HOW the Universe doesn't have to have a center --- by skimming over the fact that a person floating on the earth's oceans is similar to what a person or a planet or a galaxy is like, IN THE UNIVERSE.... an existence with BOUNDARIES BUT NO CENTER TO IT ---- I started giggling... because I can't take him seriously.
Just because you're floating on a raft --- and you could go around and around the world, without ever finding THE CENTER of the Earth ---- and you're in no position to know the CORE of the Earth.... doesn't make the Earth having no center to it!
What Tyson and all these other scientists expect us to do ---- when we hear them use the earth's upper crust analogy (as to why the Cosmos also SHOULD have no center "and still be a perfect entity/existence..... supported on the back of a turtle that goes all the way down) --- is just to shut up and stop pestering them (because THAT, to them, show we are really educated, not "childish," the convoluted logic goes)...
That is, they expect us to go:
"Wow, I didn't think of it like that... yeah, you're so right... there is no way you gonna find a center to the Earth, 'cuz, as you said, you could walk or sail around the earth over and over and never find a center to that spherical object floating in the blackness of space..."
But, Mr. Tyson.... there IS, IN FACT, A CENTER TO THE EARTH...
Just because YOU or I or some wise man doesn't know it or doesn't have a way to getting to it... doesn't mean it doesn't exist.
LIKEWISE, just because we don't know it, just because we CAN'T get to the center of the Universe ---- which was, according to these very people, supposed to have started from a singularity many, many trillions of times smaller than an atom, WHICH HAS A CENTER, by the way, a universe that started to GROW FROM WITHIN "not expanding into nothingness," etc ---- it doesn't mean it doesn't exist.
The "center" of something is nothing magical.
It's just a place where MATHEMATICALLY --- or gravitationally or by means of some other space-time METRICS ---- it is in the "middle" of all other things...
The reason we CAN'T know where we are, in the Universe, is because our cosmic horizon is only ~13.8B or so every which direction.
The reason we can never know where the center of the Universe is... is NOT because we're completely stupid, like some Stone Age man floating on a raft, adrift in the open oceans!
But by logic and by "cosmic law"/Hubble Constant.... at least currently, we know the diameter of the Universe is close to 100B light years.
And by THAT VERY METRIC --- with that imaginary cosmic yardstick of 93B light years --- there indeed IS a center to the Cosmos... because all you have to do is just pivot, rotate, and angle that "93BLY" yard stick in every direction.... and there is a CENTER to the whole endeavor...
Anyway, saying we know every major contours of the Universe, today, in 2024.... is like what Sir Eddington saying how HE & the best and brightest of HIS GENERATION, of he early 1900s, already knew every major aspect of earth and the Universe .... with nothing to do except for post docs to flush out the boring, tiny details.
Eddington was IN NO POSITION to know any such nonsense.
In 200, 500, or 3,000 years, humans will know much more about the Milky Way, the local group and its neighboring clusters, as well as the larger Universe, in terms of both its constituents and contours...
Saying, in 2024, that "the Universe is made of 5% Baryonic matter, of which we and planets and stars are made.... 25% Dark Matter (Planet Vulcan stuff), and 70% Dark Energy, exotic Planet Vulcan stuff)...." is like saying, in Aristotle's time, "The world is made of Earth, Fire, Air, and Water..."
Those are just pop culture beliefs & norms that every epoch's "best and brightest" like to engage in... to show the rest of the little people that WE NEED to give them money (via the government, via generous taxes).... so they (those few "best and brightest") could, with plenty of leisure time on their hand, come up with endless & deep sounding thoughts for everyone to hear...
But REALITY ---- or the contours and/or constituents of what we describe as the Cosmos.... as some wise guy (science fiction writer?) once said ---- is stranger than fiction.

The Earth DOES HAVE A CENTER!
