The entropy of systems

Stoat:
Time varying fundamental constants would be in agreement with this theory. I have not read the text yet. Maybe something to chat about in the next few days...

Merry Christmas!

Hi GD, hope you, and everyone else on the board, has a good christmas and new year.

I had a read of the abstract and will read the paper after I've destroyed a few grey cells with Glen Morange. If we have an exponetial collapse of the speed of light from something vastly greater but the speeed of gravity doesn't fall, then we can have electromagnetic constants which are changing but extremely slowly, due to the influence of the greater speed of gravity energy, topping them up as it were.

The blue eyed boys and girls of CERN are, I believe, quietly dropping Einstein in favour of Lorentz here. Good in some ways but it is still based on ad hoc repairs to the big bang theory.

Hello Stoat,

Here are a few excerpts of a text I found at the following link:
astronomy.swin.edu.au/sao/guest/davis/

"The fine structure constant, denoted by the greek letter 'alpha', is a combination of three more familiar constants, the electric charge e, Plank's constant,h , and the speed of light, c:

In rough terms is a measure of how tightly electrons are bound to protons in an atom and therefore effects the spectra of light they emit."



"The increase in the fine structure constant "alpha",

can be explained in two ways: (1) an increase in the value of e or (2) a decrease in the value of "hc". We can immediately see from the equation for the entropy of a black hole that these variations affect the value of black hole entropy in opposite ways. When "hc" decreases, entropy increases and the second law of thermodynamics holds. However, when e increases, entropy decreases and the second law of thermodynamics is violated. Thus black hole thermodynamics suggests that the increase in the fine structure constant is due to a decrease in Plank's constant or the speed of light."

Stoat:
Is this not the varying speed of electrons I have been talking about?
-I Think it is Plank's constant which is varying with time-.
The varying speed of electrons with time and distance means ...for example: varying energy in a mass with time and distance.

Do you think this makes sense?

Hi GD, yes, it does make sense. In a couple of other threads, cosmicsurfer's and the gravitational lensing thread, we've been talking about what happens on either side of an "event horizon." I argue that the space there takes on a negative refractive index. A photon crossing this surface can be absorbed by a sea of super conducting electrons, and be reemitted at faster than light speed.

A point to bear in mind. The speed of light drops exponentially but the speed of gravity doesn't. This is a very fast "cooling." Matter condenses in this. We would have a space which is gravitationally "hot" and electromagnetically very cold. This is a Bose Einstein condensate i.e. it has zero entropy. This suggests that we live in the part of the exponential fall off curve, where it's almost a flat line. Gravitational energy is topping up electromagnetic energy,

Of interest, I think, is that every bit of matter has an "event horizon" for an electron it's much much smaller than h. Move an electron and its internal electromagnetic frequency falls; once near the speed of light, and remember that the electron is spinning at the speed of light, the electron can draw on its gravitational energy. A vast source of energy but a source that can only deliver a trickle. It looks like zpe but I don't know how it can be shown to be zpe. (Reading that clumsy sentence back to myself, made me wonder if there would be sense in thinking of an electron as a tiny helicopter, its "rotor blades" stall. Maybe as a heuristic.)

It makes sense?

Then you don't agree on what I claim is "gravity" then: - the continual slowing down of the electron (with changing time and distance) - ?

Hi GD, I simply don't know enough to give an answer on what gravity is. I suspect that the half life of the electron is not infinite, that its entropy increases but it's very slow, billions and billions of years. I suspect that gravitational and electromagnetic forces can be unified but haven't the foggiest about how to go about doing it.

My game plan is drink beer and eat crisps, while waiting for some young whiz kid to come onto the board and explain it all. I hope he/she looks like Danny Kaye, singing "the king is in the all together" but I'll settle for something so obvious that it will be just plain beautiful. [8D]
