Bonker writes "Neat news from the Beeb. It turns out that data collected from observation of quasars indicates that the fine structure constant of the universe, aka 'Alpha', may have changed since the universe began. It may have been very slightly smaller than it is right now. The article hints that other constants we're familiar with, such as high, holy 'c', may also vary over time. Of course values can't have changed dramatically, because that would mean that low-weight atoms such as carbon would be unstable, and without carbon, there wouldn't be anyone around to measure the fine structure constant anyway." We ran a story about this last year. It looks like the team has continued to check their work for errors and hasn't found any yet.

Alternately, if we're shrinking on a hyperbolic space (ie staying the same size on an ever growing space), then pi should be getting smaller.
Actually, unlike 0, 1, and e, pi is not "a fundemental constant", but a convenient artefact that allows circles and spheres to be expressed. For example, one can use any number "k", and express pi in terms of "k". The definition of k would be different, but that's ok.
For example, if k were pi/4, we would say that the circumference of the circle is 8kr, and its area 4kr^2. For diameters, circ = 4kd, and area = kd^2. This make the circumference and area k times that of the circumscribing square.
Also, I have played with a set of mathematics, that makes the surface of the sphere 8 pi r^2, with pi=3.14159265359 &c. This has an effect on the "rationalisation" in physics, where 4pi gets replaced by 8pi.
Mathematics has a lot of preconcieved notions in it.

All that is required of pi is to have the circumference of the circle expressiable as a product or quotient with just one irrational. Whether you call 3.14159265359 n/k or nk, and the value of n are pretty much free variables. Ergo, pi is not a fundemental constant.

Just because you can throw excellent links about 3.14159265359 at me, it does not mean that every culture, or separate mathematical tradition is going to write the circumference of the circle as 2k of the radius.
I've seen good cases for using 6.28318530718 as the fundemental constant for the circle.
Therefore "pi" is not a fundemental constant, but just a convenient expression for the circle and circular things.
On the other hand, "e" will always evolve from logarithms. "e" was not set before-hand, like pi was. The definition of pi is simply the circumferance divided by the diameter of a circle. Every other expression, formula and so forth relate to this definition.
But ... there are other properties of the circle that can set a ratio, such as the circumference divided by the radius. Given that the radius is the correct mathematical expression of the circle (all formulae relate to the radius), then the constant of 6.28... is "more correct".
The values of 0, 1, and e are determined from the outcomes of pre-existing conditions. 1 from a pre-counting era, and 0 as a symbol for an empty item [I recognise something like eight or nine idioms for "0", and several different symbols].
For example, remember that "0" is the "empty column". The "column" could be an empty tray by itself, or one in the middle of others. For example, if your purse is empty, it's a different story to if you have a $1 and a 5c peice in it (which involves a different kind of 0, $1.05, and this is a different kind of zero to the one in "3 hours [0 min] 22 sec". There's also the "dash zero", filling a column with a dash to indicate that it's empty.
My studies of Egyptian mathematics seem to indicate that the values pi/4 may have been the form used.
Pi as 3.1415926... seems to be established when the circle was described in terms of its diameter. A circular inch, for example is an area of a circle of one inch diameter.
The fine structure constant, and its related fine structure hundred [the latter is my name for 137.036...] is something that evolves from physics, and is not "set before hand".

At the presision our senses operate, the outside world appears Euclidian, so our internal representation of the world, the nouminal world, all that we experience, IS Euclidian, and pi is always the same. But the world is, in fact, not Euclidian at all. Everything 'out there' operates according to a set of rules that operates very much like the set of rules 'in here', but not quite.
If we someday build a true artificial intelligence, it would be interesting to build it such that its internal view of the world was based not on our own Euclidian, newtonian minds, but instead on what we know to be a representation closer to actual external reality.

The article actually doesn't really hint that 'c' is changing, which is good, because it's not clear what would be meant by that. The article says that several physicists have previously wondered if it could change. It then goes on to quote a modern physicist as saying that they were wrong.
I think c is best thought of as a man made constant. Just as I might say that there are 2.54 centimetres per inch, I can say that there are ~3*10^8 metres per second. Neither of these really contains any information about the universe outside of our perception of it. It is simply a statement of how one one system of measurement compares to another. 2.54 centimetres per second evaluates to unity (the number 1, with no units) if you actually evaluate it. Likewise, physicists commonly use unity as the speed of light, because in a very meaningful way, it is.
If I suddenly magically increased c by 10%, that would be indisinguishable from stretching the universe by 10% in every spacial direction. Consider that the speed of light it essentially unity, and that expressing it otherwise is really more a statement of our systems of measurement that we use than of physical reality. This makes it seem silly to say that I have magically increased c by 10% and makes it seem more reasonable to say that I have stretched the universe by 10% in every direction.

Before, we could measure lenghts more accurately than velocities, and so we defined c in terms of meters per second.
But now, since we can measure velocity with more precision and accuracy than distance, a meter is now defined in terms of the length of a second and c.
Now:
The second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom. (think atomic clock)
The speed of light in a vacuum is defined to be exactly 299,792,458 meters per second.
The "length" of a meter then is a derived value!
So there are consequences of a changing c, since a different value of c will change the amount of energy needed to accelerate a mass, and will affect the structure of the universe....but I'm not sure how they would go about figuring that out.
Re:No hints about c (Score:2, Insightful)
c is the speed at which electromagnetic waves propagate. calling it the speed of light is somewhat of a misnomer; it might be better to say that light moves at the speed of propagation of electromagnetic waves, since it is, after all, an electromagnetic wave. Furthermore, it turns out that the wave equation implies that c = 1 / square_root(e_naught * mu_naught), where e_naught is the permittivity of free space (ratio of charge to electric flux in vacuum) and mu_naught is the permeability of free space (ratio of current to magnetic flux in vacuum). These two are experimental constants which the speed of light happens to depend on (although now the speed of light is taken to be a fundamental definition). Therefore, an increase the speed of light by 10% would imply an increase in either or both of the fundamental constants, which may have drastic effects, comparatable to G (the universal gravitational constant) being 10% greater.

Each change improved the reproducibility of the best length measurements, given the technology at the time the change was made.
The observations that suggest alpha varies are based on comparing wavelengths of light from different atomic oscillations, potential distance standards similar to (3) above. They appear to vary relative to each other. If you want to attribute this to varying c, which one is the reference yardstick?
For our present technology the most reproducible clocks and yardsticks are atomic oscillations. If these lack relative constancy and you choose the frequency of one as your time standard and the wavelength of another as your length standard, you will apparently observe a changing value of c. However, the direction and magnitude of the change will depend on which pair you choose. If we had really independent distance and time standards (and it was clear which was which) it would make sense to consider c an experimental quantity. Since we don't we have just chosen one standard (a particular oscillation of cesium), and c is a defined constant.
Similarly, the electromagnetic quantities "epsilon nought" and "mu nought" were once experimental quantities, but are now by definition exactly {10^7/(4 Pi c^2)} and {4 10^-7 Pi} respectively. This means that the coulomb is no longer defined electrochemically: it is a derived unit, not a fundamental one in the SI system.

Think of c as an aspect ratio. The ratios of the space dimensions are (usually) 1, which is like a computer screen made of perfectly square pixels layed out evenly; if you rotate an image on that screen, it doesn't change at all. If the ratio is not 1, then rotating the image makes a difference, and the distortion (circles becomes ellipses, faces get squished, etc.) is dependent upon the ratio.
Where is this 'distortion' then, in space-time? It is all the weird things that happen when objects approach the speed of light. Moving between reference frames is like rotating the screen, and thus the value of c influences these behaviors. So what? Even if you're not a space traveler, things like the color of gold are dependent on this number. Shift 'c' enough, and it's lead that's pretty and gold dull.
The units we use may be convenient and flexible, but space and time are not arbitrary, even ignoring relativity. For example, you could measure the speed of light in terms of (diameters of uranium nuclei) per (period of light emitted by first ionization of hydrogen) or any such, and it should be clear that changing this velocity would require rewiring the universe.

Basically, that would change its orbit, really noticeably, but that doesn't matter.
The earth would be a different distance from the Sun- that would have devastating effect on the biosphere. It would get really hot. But that doesn't matter either.
Far worse- all of the nuclear bonds holding the earth together would suddenly be 10% too short. The earth has been shrunk by 10%, and it doesn't like that. The earth would explode back out to its original size, overshoot, and finally relax to its original size; liberating immense energy. Everything on the earth would disintegrate.

It may be more tangible, but it isn't "more constant." The length of a yardstick is determined by the number of atoms on a typical line running from one end to the other times the average distance between their centers along this line. The number of atoms won't change if you change c, but the distance between them (which is determined by the interaction between charges, which is mediated by photons, which move at c) will--it will change in exactly the way to make you think that c hasn't changed.

As philosophically nice as that would be, this just isn't true. The spacing of atoms and molecules in bulk matter is mediated by electromagnetic forces, but is determined by the solution to the local Schrodinger equation in a periodic potential, and it is not at all straightforward to evaluate this spacing given only fundamental constants and the composition of the material. In particular, the spacing in question definitely does not vary linearly with c.
To take an example from a previous comment, suppose you wanted to express c in terms of the radius of a U-238 nucleus and a Lymann-alpha photon period. Using only first-order effects, the energy of the Ly-alpha photon varies as 1/c. Since h is experimentally determined, we'll suppose it doesn't change (you'd notice immediately if it did), in which case the Ly-alpha period is linear in c.
For the nuclear radius the matter is more complex. For the droplet model it becomes a matter of QCD to determine the effective nucleon radius. If we use the less realistic but easier point-particle non-local-potential model, it depends primarily on the mass of the pion: the volume depends (to rough first order) on c^2, so the radius goes as c^(2/3).
Finally, the measured value of c goes as length over time, so this measurement varies as c^(2/3-1) = c^(-1/3). So you really can't claim that every possible measurement of the value of c is invariant under changes in c, because this one clearly isn't.

As for your wavelength vs. nuclear radius thought example, I don't know enough about the inner workings of quark stew to be sure that there isn't some hidden dependence on c that would make it all work out.

Re:Already predicted by Standard Model of physics? (Score:1)
You're right, it's not a new idea. The first physicist to suggest time variation of basic constants seriously was P.A.M. Dirac. His reasoning was a bit fanciful. He calculated certain dimensionless numbers by appropriately combining various dimensionful basic constants of physics and found that he got very large numbers.
Since the numbers were very large, and one knows that the universe is very old, Dirac proposed that the great age of the universe was the reason the dimensionless combinations were large numbers: it was related to the large age of the universe.
If this was true, it then followed that the fundamental constants had to be varying with time and would have been different in the very early universe.. This is called Dirac's `large numbers hypothesis' for obvious reasons. It's a wild, but a very imaginative suggestion.
Yes, but the kind of change of alpha being discussed in the article is most definitely not a part of the established standard model.
Strictly speaking the standard model is only partially unified: the electroweak part or SU(2)xU(1) is unified and matches well with experiment, but the strong interaction SU(3) is not so easy to unify with SU(2)xU(1). The simplest GUT to accomplish the SU(3)xSU(2)xU(1) unification was the minimal SU(5) GUT, but it predicted decay of the proton at a rate which was experimentally ruled out some years ago by direct measurements.
The best bet for grand unification of strong, electromagnetic and weak interactions at the moment would be some form of what's called the minimal supersymmetric standard model. This theory is beyond the standard model because it predicts supersymmetric particles, which are so far unobserved.
But this theory is, like the standard model, basically a theory of particle physics alone. It doesn't even address gravity, much less the possible time variation over long times of fundamental constants evaluated at a *fixed* energy scale. Such a time variation breaks the Lorentz invariance of all of these theories. For that matter, such a variation breaks the general coordinate invariance of general relativity. If what is being said is true, and it is a very big if, it requires a radical change in the accepted theories.
Well, true, but you conflate several ideas here.
There are so-called running coupling constants in the standard model and in the various grand unified models (excluding gravity for now). So for example, if two electrons smash into eachother at very high energy, say 100 GeV or so, then the appropriate value of alpha to use in calculating their interactions is more like 1/127 than 1/137.
This running of the coupling strengths is well tested and is predicted by quantum field theory. If the strong, electromagnetic, and weak forces are actually part of a GUT, and the big bang theory is correct, then at some early time in the history of the universe, the average energy of interactions of electrons would have been 100 GeV for example.
At that time it would make sense, on average to use a value of alpha which is 1/127, but that in no way means that this larger value of alpha should be used at that time for two electrons which collide with much lower energy. If they collide with very low energy, the appropriate value of alpha is still 1/137 if the standard model is correct. You see the distinction?
The observations in question are actually of atomic transitions in very distant gas clouds, so they involve very low energy interactions of electrons with positively charged nuclei. So the running of the electromagnetic coupling, alpha, is not relevant to these measurements, and if any real deviation in the observed atomic transitions can be shown from what is observed at the present day, then it means atomic structure has changed. That would mean the laws of physics are really varying as the universe ages. It's quite radical. It means throwing away the standard model and general relativity.
Yes, this is an effect of the running coupling constant in GUTs, together with the big bang theory. At high temperatures, like existed in the early universe, all of the couplings would have looked the same.
Yes, interestingly enough, such plots showing how the electromagnetic, weak and strong couplings run to the same value at a given, fixed energy were actually used early on to argue that grand unification of the SU(5) type probably was occurring. There were errors in the original calculations though, and it turns out that the couplings don't actually become the same, they miss as shown in the plot you reference. That's one of the reasons why supersymmetric unification is proposed: you have more parameters and you can make the three couplings meet ... it's not really a very good
argument if you think about it a bit!
Yes it is certainly pointing to something new, if the result is correct. But there are many problems with it.
There is the obvious unpleasantness that you don't really see a clean result: you can't really say that we see that spectral line X in atom Y was different at such and such a time and place than it is now. Instead you must look at a statistical analysis of many lines over many gas clouds, and extract a best guess on the value of alpha as a function of time (actually, redshift) in the universe, using a theoretical calculation of how atomic lines should depend on alpha. It has to be said that such a calculation is far from trivial to do for complex multi-electron atoms, and in fact can't even be done all that accurately.
Indeed, people who did the same kind of observations previously, concentrated on alkali metal doublets which are produced in (effectively) simple single electron atoms, for which one has a much better hope of understanding the theory well. These observations produce a null result for the variation of alpha, it's only when you add in the more complex metals as these researchers do, that you see a non-zero effect.
My feeling is that it is very interesting, but it's most likely that when a more extended analysis and more observations are done, there will probably be nothing left of the effect, except possibly a better null result than one had with the alkali doublets.

Let me explain. Both relativity and geodesics posit that we must modify the notion of space-time or space in the large scale, to deal with the fact that the "flat model of space/time" is inappropriate in some conditions.
In geodesy, the size of the earth is a constant that you use to convert angles into length, and in relativity, the speed of light is something that you convert time to length.
Assuming that you have other ways of recovering time and length from ancient sources, you can recover therefore an ancient speed of light.
Actually, the book that the constants table comes from in the first place, goes into the physics of defining standards [including endlength prototypes], and their dependence on different universal constants, in some length.... The speed of light in this is not assumed constant...

It seems possible that our disciplines of science and natural history might actually be driven farther apart, as we lose any reliable base indicators on which to base assumptions about the past.

It's not possible to go faster than the speed of light in a vacuum. However, it is possible to go faster than light in some medium.
This actually happens fairly often in nuclear physics. Radiation given off by, say, radioactive waste in a nuclear power plant's storage pool can go faster than the speed of light in water. When it does this, you get the eerie blue glow everyone imagines with radioactivity (which usually isn't really there).
This effect is called Cherenkov radiation, unless I've forgotten how to spell.
It is not possible for any medium to speed up light, so far as in known.
The simplest way to understand why light slows down in a medium is to think of it this way:
Light is zooming along at its full vacuum speed, right? But, there are all these atoms there! Zillions of them! So, light runs into an atom. Luckily for light, the way this works is that it temporarily "charges" the atom, which then almost immediately (but not quite) "discharges" a photon going in pretty much the same direction with the same frequency. Depending on how many atoms there are, and how the atoms behave, this can have varying effects on the light.
This isn't really particularly accurate, but it's easy to understand and more or less vaguely similar to how it works.

Actually, this is also, technically, incorrect. The speed of light is a constant. Always. Light always moves at light speed. Now, the time it takes for light to pass through various mediums is different, but this is not because the light is being slowed down. It's because the light is hitting the atoms in the medium and is kicking the electrons in the atom to a higher energy state. When the electron falls down from its higher energy state, it in turn release a particle of light. You could go so far as to say that it's the same particle of light. With denser mediums, light takes longer to get through. In the sun, for example, the plasma surrounding the fusion core is so dense, the light from that fusion takes many millions of years to reach the surface. During those millions of years, the light is always moving at light speed. It just keeps running into stuff.

In many cases, there isn't alot of agreement. Sometimes, the best they manage, is "this one has to be really old, can't be any younger than 1 million". Other times, they are complete anomalies, that they won't even venture guesses.
But this isn't proof that it's crackpot science. It's evidence that the whole thing is undergoing refinement. No grand conspiracies lurk here, to hide the truth.

I might even have an explanation, if you care to hear.
You claim that he created the earth in seven days (forgive any minor mistakes). Yet, the earth itself determines just how long a day is. Not the sun, not anything external. Does the term day have any exact meaning, if the earth isn't fully formed, and rotating? The bible doesn't say that it was created in 3.45 x 10^29 vibrations of the cesium atom, or anything like that. Just "day" (or am I wrong?). And then, there is an old tradition of even using the term "day" poetically, when it doesn't mean ~24 hours at all. It is possible, that maybe it means that God created the world in seven stages, each of indeterminate (and not even equal) duration? And finally, it would be interesting to know which word is used in the original Hebrew, and if it was ever used in a context where it doesn't mean approx. 12 hours of daylight + approx. 12 hours of night. And the absolutely best part of all this is, I'm not even coming close to asking you to change a core part of your beliefs. Your morality, which I respect, isn't altered by this at all. And you might even come to appreciate yet another perspective of the bible... one where there is much more poetry in addition to the lessons it teaches you about life. I find it hard to believe that someone could be so inspired to write down the story of creation, without attempting to use metaphor of one form or another. Neither atheist or believer will deny that the entire event was anything but awesome, mind you (and what could be more awesome than a being that would think nothing of performing a creation that spans several billion years?).
And please, don't take this the wrong way. But christians in particular, seem to want to argue what I would think amount to insignificant details, when all it does it make them look like fools to the public. And the greatest irony is, instead you could be using that effort to teach them the real truths that you really do have, which the non-religious seem to lack. Why? A god that teaches his worshippers to run around trying to ban biology textbooks isn't very worthy compared to a God that can't be bothered to worry about that because his followers are busy trying to teach people to be decent to one another (no matter what the details of their origin are).
