I have often wondered what gives a neutron the ability to just keep going and going and going... for so long.
Is there conservation of energy at the quantum level? If so, doesn't that imply friction? Assuming that we can rightly expand the meaning of friction to include "the interaction of individual quantum stuff with its quantum soup".
Maybe I shouldn't think that the description -- "individual" -- can apply to the quantum realm? Has this ever been addressed?
Is there a relationship between dark energy and the quantum world that gives a ... "Something"... to all matter, thus keeping it all in a seemingly, or impied "constant" energy state? Is there a relationship between the rate of expansion of the universe and the lessening quantum energy levels of matter?
In short, why do things spin? Why doesn't the universe seem to be able to deliver a knuckle ball?
Does a graviton spin? I would guess that it does not, and that it is the reason that it is so "different".
btw... I am aware that a Neutron is many orders of powers larger than Planck level QED. That only improves the mystery.

A trillion years is a long time to conserve that which is a mystery? No?
I think that one concept that I am weak on is "Time".
I forget that at the holy grail "Speed Of Light", there is no "time".
My bad. But if this is the case then what meaning has "Quantum", as it is all outside of "time"?
I still want to know about how we all just accept that a Neutron can spin for eterinity without any apparent "help" from an "outside" that can't exist.

You don't need energy to keep something spinning.
Ok. Saying that there are "no forces" at those levels, how does the universe "hang together"?
I would think that "being" impies "energy"?

Yes, things just merrily spin because they spin, and because nothing stops them.
The rest of your post is nonsensical as far as I can tell.
EDIT - Forces can exist without exerting energy. You should brush up on your classical mechanics.

Ok.
Thank you for such an illuminating treatise. I would never have dared think that a question about Quantum Mechanics would be answerable to Newtonian Physics. Thanks for giving all you have to give. Now go lie down with a sheep and try not to father any more of your kind.
BBBBaaaaaaaaaaaaaaaa! Daddy! Where are you? Bbbaaaaaaaaaaaa!
For those who are new to RHP... the "thousand dead babies" and I have a history. Like "No Sheist!"

Classical Mechanics?
Ok.

I won the Jet Propulsion Laboratories award for physics student of the year when I studied classical mechanics. I've taken an upper division courses in quantum mechanics for physics majors at the top physical chemistry program in the world.
You're making no sense.
EDIT - By Planck State you mean a singularity right?
EDIT2 - By Noether's Theorem conservation of angular momentum follows from the angular symmetry of space. The extension of this theorem into quantum field theory is called the Ward-Takahashi identities.

Why would a person argue with such a genius as you?
Even though you can't quite get the singular and plural of " I've taken an upper division courses " figured out. Sigh.
Why do you insist on being such a toid? You are a very minor league elementary school teacher. Which part of "You are no genius" do you not understand?
Go away. You are bothersome.

There are no spaces between quotes and what they are quoting. Where's the rest of the "Even though" sentence?
Now another idiot tries to wish me away. That doesn't work people!

I usually say that if your argumentation is as low as criticizing spelling and grammer, and name calling, then you don't have any arguments at all.
Your thread title "What makes a thing spin for a trillion years?"
I would answer: "Not yet it hasn't, as not even the universe isn't that old."

TOID
A TOID (TOpographic IDentifier, pronounced toyed) is a unique reference identifier assigned by the Ordnance Survey to identify every feature in Great Britain. The identifier consists of two parts, a prefix ‘osgb’ and a unique identifier that is 13-16 digits long. Within GML, a TOID is also referred to as an FID (Feature Identifier).

Small sized devices
Radioisotopes which undergo spontaneous fission
Certain isotopes undergo spontaneous fission with emission of neutrons. The most commonly used spontaneous fission source is the radioactive isotope californium-252. Cf-252 and all other spontaneous fission neutron sources are produced by irradiating uranium or another transuranic element in a nuclear reactor, where neutrons are absorbed in the starting material and its subsequent reaction products, transmuting the starting material into the SF isotope. Cf-252 neutron sources are typically 1/4" to 1/2" in diameter and 1" to 2" in length. When purchased new a typical Cf-252 neutron sources emit between 1×107 to 1×109 neutrons per second but, with a half life of 2.6 years, this neutron output rate drops to half of this original value in 2.6 years. The price of a typical Cf-252 neutron source is from $15,000 to $20,000.
