Thanks for the interesting link, Steve.
From a ball of positive charge to an amalgamation of three quarks to a "quantum mechanical object that exists as a haze of possibilities until an experiment forces it to take a concrete form" - a proton is "the most complicated thing you could possibly imagine".
Actually, I don't care to waste time searching through 541 pages of Lounge Room nonsense, thanks.
I rarely even, very rarely.... click on any post of such lengths, because I know they contains endless babbling and debating that bores the death out of me.
Besides, this being the Lounge area, my comment was of a sarcastic nature.
“Sarcasm is the lowest form of wit but the highest form of intelligence.” - Oscar Wilde.
On this thread, we try to combine intelligence with wit, however some may regard it as a work in progress! 😉

I was curious what the Latin word, perhaps a particple, "Emense" meant... perhaps it would have been better to employ "Immense"?
It gets worse:
Surely the word OM is part of Buddhist Chant? Om, mani, padme, om... an' all that.
With two spelling mistakes so far, surely you must admit a certain linguistic uncertainty? Therefore a doubtful source?
More certainly, though we admit the Coriolis Effect, it might be greater in one hemisphere than another.
Reason I say this is our Universe is, AFAIK, left-handed:

Don't take my autistic criticism too hard. But you are dealing with "Third Kind" here. We are mainly visual, but at the highest level can do words too. A matter of training.

Can't spot it myself!
Anyway, I am now off to Wetherspoons, Palmerston Road, Portsmouth UK for breakfast. 11.15 AM. A mere £2.99 with coffee!
I have a voucher.
Bargain! 😀

The search for hypothetical right-handed (sterile) neutrinos has been underway for some time, but it is possible that cohesive evidence for their existence may never be found.
Meanwhile, back in the practical world, neutrino astronomy is an emerging field in astroparticle physics.
Neutrinos travel across the Universe without absorption or deflection by magnetic fields, making them ideal astronomical messengers.
Because their interactions with matter are extremely feeble, sophisticated detection methods are required, such as those at the IceCube neutrino observatory.

system7 appears to have pulled off a considerable coup in the usually dull multi-way forum:

I put it down to the Greatest of Mathematicians:

I am a man, known to live intensely in the present moment:
Could it be that we overlook the Vera C. Rubin Observatory?
Certainly better than my camera:

I haven't overlooked the Vera Rubin observatory. I mentioned it some time back as having the potential to improve the +/- 7% uncertainty that Dark Matter exists.
I've been reading about Loenhard Euler, whose work in mathematics is so vast that it is impossible to summarise here.
Pertinent to the thread, Euler wrote books on the calculation of planetary orbits and the motion of the Moon.
We owe to him the notation f(x) for a function, e for the base of natural logs, i for the square root of -1, π for pi, ∑ for summation and many others.
We live in an age of scientific wonders, which Gauss and Euler would be busy doing their calculations on, if they were still around.
This is a Kepleresque graph of the masses of various Hadrons and Mesons:
Very central to String Theory as an explanation of Regge Trajectories. Guess who firmed up the theory?
https://en.wikipedia.org/wiki/Beta_function#Applications
Euler! The Euler Beta function.
I often apply the Euler Zeta function to the problem of annoyingly bright street lighting, when about my astronomical observations.
https://en.wikipedia.org/wiki/Proof_of_the_Euler_product_formula_for_the_Riemann_zeta_function
Unfortunately our local council lacks mathematicians to correctly direct our street lights down, and an understanding of colour temperature to control glare!
They are hopeless on the subject of dark skies! Sorry to rant. 🙄

Your post is replete with Wiki references, Steve, but difficient when it comes to explanations!
My searches reveal that Euler considered the Zeta function when calculating the sum from n=1 to infinity of 1 divided by n squared.
He obtained the answer pi squared divided by 6.
I await your explanation of how this relates to "the problem of annoyingly bright street lighting".
You're not suggesting that the the Euler solution is related to the fact that the intensity of light is inversely proportional to the square of the distance from the source are you?

Euler Zeta (2) sums to Pi^2 /6 = 1.644493...
1 + 1/4 + 1/9 + 1/16 ....
What this means in one physical interpretation is with a row of street lights, it is the nearest 3 or 4 that do most of the useful lighting. The rest are just useless glare.
Lamps should thus have shielded downward pointing enclosures. Colour temperature matters too, since the blue end merely destroys your night vision and yellowish is much gentler.
Terrible light pollution here even from the beach in Portsmouth! And most of it just careless design on the Isle of Wight. Jupiter and Saturn conjunction at a recent Christmas.
Modern dazzling bluish LED car headlights are a thoroughly bad idea too, for the same reason.
I care about this stuff.

We are denying about 99% of the population the chance to see the wonder of the night sky. It's actually quite an easy and cheap problem to solve.
