Fundamental Constant Possibly Inconsistent

dylanduck writes "Cosmologists have begun thinking that yet another fundamental constant of nature is, er, not constant. The constant in question is the ratio of a proton's mass to that of an electron. It governs the strong nuclear force but there's no explanation for why that ratio should be constant. If true it would provide support for string theory, which predicts extra spatial dimensions." From the article: "Researchers at the Free University in Amsterdam in the Netherlands and the European Southern Observatory in Chile discovered the variation in mu. They did it by comparing the spectrum of molecular hydrogen gas in the laboratory to what it was in quasars 12 billion light years away. The spectrum depends on the relative masses of protons and electrons in the molecule."

Is that because women aren't constant?

Well both the electron and the proton look an awful lot like periods...

If they constantly aren't constant, does that make them constant? ;-)

Speaking as a woman ... and I *am* one (that's "shar-LESTE" - not Charles T.E.)... Are you insinuating that being consistently inconsistent isn't very consistent? Because it is.

BTW - you *should* know what I'm pissed off about - you know what I mean when I say "Nothing".

Ob. Farnsworth quote

[dc29A]

Farnsworth: These are the dark matter engine I invented. They allow my starship to travel between galaxies in mere hours.

Cubert: That's impossible. You can't go faster than the speed of light.

Farnsworth: Of course not. That's why scientists increased the speed of light in 2208.

Apparently, the meaning of "constant"

[Snarfangel]

...isn't constant, either. Perhaps we can rename them "fundamental variables."

Re:Apparently, the meaning of "constant"

[fireboy1919]

No, constant is good. It's just that for very large or small values of the constant, it's sometimes different.

1!=2 is, for example, always true, except for with very small values of 2 or very large values of 1. Possibly you need both small values of 2 and large values of 1.

[Bravoc]

Seems to me, that since these occour naturally in our environment, we should call them..... environment variables Sorry, I couldn't resist

Re:Apparently, the meaning of "constant"

Urgh... that will mess up optimization.

Well, that's what God gets for using C++. You think you've got a well-designed system, then you realize that to make your next set of changes work you're going to have to throw in a bunch of const_casts or mutables.

You can tell He's new to object oriented programming, too - he's got this whole overeager class hierarchy of tau derived from muon derived from electron, top derived from charm derived from up, and on and on, but then when it's finally time to put together the universe He gets sick of the whole thing and builds all His matter from the base classes!

Does this mean

[LoonyMike]

that I face the risk that the first 100 digits of PI that I have memorized could change, and the knowledge becomes useless?

This is actually true, I do know the first 100 digits by heart.

Pi = 3.

Re:In other news..

[frdmfghtr]

Pi = 3.

Maybe where you come from, but in California, it is 3.

Recent discoveries in the legal profession have left scientists, many of whom still linger romantically in the Newtonian world, scrambling to catch up in the field of New Causality. In a case last month, a judge in Sacramento ruled in favor of changing the value of pi, thus acquitting a tire manufacturer of making tires that were not fully round. An appeal by scientists was thrown out for lack of evidence when the small courtroom could not physically accommodate a fully expressed representation of pi. The oblong tires in question were produced at the retrial, the judge said they looked round to him, the defense played the race card, and the value of pi was changed to 2.0.

Re:In other news..

Arbitrarily changing universal constants can be a bad thing.

I remember one time, in my youth, while partaking of illicit mind-altering substances, looking at a window. More specifically, a small piece of stained-glass hanging from the window. Hanging by a suction cup.

A circular suction cup.

This piece of stained glass had been hanging on that very window for years.

Deep in thought, looking at this stained glass, I thought to myself "You know, if I was God, I'd probably round off pi to a million decimal places or so - it wouldn't really effect anything and it would make things much simpler". At which point, this stained glass, hanging from a circular suction cup, which had been there, unmoving, for years, due to a failure in the circular suction cup, fell to the ground and shattered.

I learned my lesson - don't mess with universal constants.

Re:In other news..

[Anonymous Coward]

Ah, but Pi does equal 3...
...
...for small values of Pi and for large values of 3, anyways.

Huh?!
