The strong-force coupling constant is typically given as 1, the electromagnetic-force coupling constant is typically given as 1/137. In a region of space where there exists the thing we call a gravitational field, you should expect to see this 1:137 relationship change. The fine structure constant can be measured to about one part in a billion via the quantum Hall effect, but the Earth's gravitational field isn't adequate. The GPS clock adjustment for GR is 45,900 nanoseconds per day, and there's 86,400 seconds to a day, so the difference is less than one part in a billion. You need a stronger gravitational field, namely the sun's.What exactly do you mean “reduces with gravitational potential”? How exactly would such a reduction be a “test” of if “a gravitational field was the result of a gradient in the relative strength of the strong force and electromagnetic force” as you asserted?
Not directly. The Planck mass is huge. All stable particles with mass are charged, using a Planck mass is about as useful as using an asteroid with a bit of net charge.You’ll note the part where it directly says “α is the ratio of their electrostatic repulsive force to their gravitational attractive force.” So yes directly.
The mass of the sun isn't that important. We measure depth of field via gravitational time dilation. The fine structure constant should vary in line with that.How observant of you to note that the plank mass is larger than the mass of an electron and similarly very observant of you to note that there are two charged masses in this consideration. Any other obvious observations you’d care to, well, observer. I’ll note that you didn’t make note of the fact the mass of the sun is 1.99 x 1038 times the planks mass and you’ve only got one of them in your “test”.
No closer, because I fulfilled it 3+ years ago. Here's a bit about it.An aspect one could observe as being noted on page one of this thread, as well as your claim that…
I can tell you why the fine structure constant takes the value it does, and why it's a running constant.
A demonstration that has yet to be observed. Two years have past now, are you any closer to actually fulfilling that claim?
The permittivity and permeability of space. They're combined as vacuum impedance, or "the strength of space". You see hints of this kind of thing from time to time. See for example New Physics at Low Accelerations (MOND): an Alternative to Dark Matter and this bit on page 5:“different environment”? What’s different about the “environment”?
"We see that the modification of GR entailed by MOND does not enter here by modifying the ‘elasticity’ of spacetime (except perhaps its strength), as is done in f(R) theories and the like."
Fine. But you're maybe missing the point of all this. If a gravitational field is only there because of a inverse-square gradient in the electrodynamical properties of space, the αg is somewhat derivative, and big G is just a dimensionality/unit conversion factor anyway. And since mass m is just E/c² before you know it gravity has kind of slipped between your fingers and is history instead of mystery.Oh and if you compare “α = e²αg/4πε0m²G” with “α = e²/4πε0ħc” as you assert to do then you will find αg/ m²G = 1/ħc
I know what NIST says. The electron has unit charge, and whilst it's an electron, that's all it ever has because charge is conserved. The effect of that charge varies if the properties of space vary. But then people make the mistake of thinking that elementary charge varies. It doesn't Because charge is conserved because charge is topological.Why? As “e is said to be "effective charge", and "effective charge" can vary (see your own citation NIST)?
Of course it is. Einstein said it varies, and we can see it varies.Just to give you a hint that’s why it’s called the “effective charge". Also “Since permittivity is intimately related to permeability” that means μ0must remain constant or change in such a way that c does not remain constant. Oh I know why, because all you want to actually say is just that c is varying.
I only left it alone to keep things simple in this discussion. I said it has to vary a few years back. Have a read of this recent physicsworld article Can GPS find variations in Planck's constant? You might have to search for it because somebody was saying the links only work after you've already visited the page.“nothing in sacrosanct”? You mean except for your desire to have c vary as opposed to just the "effective charge" varying (as your own citation claims) or even both ε0 and μ0. Heck you could have even went for ħ but choose to leave it alone for now to preserve the sanctity of your varying c.
It always has gravitational potential energy in relation to the earth, but the energy you supplied to the brick has departed the system. The brick will never fall back to earth. It's lost in space along with the energy you gave it, gone forever. ETA: it hasn't "gone" in the sense that it's mysteriously vanished, conservation of energy applies.Wait, what? “the energy you supplied has gone”? Has gone where in you notion exactly? Under the consideration of binding energy and bound states “the energy you supplied has gone” into increasing the gravitational potential energy of the brick in relation to the Earth. Unless of course your claim is that as the brick get higher its gravitational potential energy increases and then suddenly at some mysterious point “it escapes the earth's gravitational field” and no longer has any gravitational potential energy in relation to the earth.
I mean constants aren't constant. Also see this bit of wiki. There's a space/time parallel between climbing out of a gravity well and the expanding universe, so if the fsc varies across space it will vary over time too. Next time you hear somebody prattling on about the Goldilocks anthropic multiverse and the "fine tuned fundamental constants", remember all this. I'm not lying to you or trying fool you into buying some "my theory", I'm just ahead of the game that's all. Look at the time, I have to go.You mean “constants aren't always constant” unless you just want them to be, so the constant c will vary. If the "effective charge" varies then so does the fine structure constant without any change in the other, well, constants.
