That is...
After a few billion odd miles of going up and down really fast the little photon goes a bit red with all the exertion...
All that needs to be shown is that high frequency waves carry more information than low frequency waves (and that is clearly the case). And...
---
either, information must be lost in transmission (the probability of losing information tends to 1 with time)
--- or, entropy of an isolated photon must increase (... not sure - <edit>but Jim reckons its all about the internal energy of jelly ...)
madness...
<edit> As for an invention *shrug* I guess its a way to tell how old/far the stars are not how fast...

Isn't this The Theory Formerly Known as 'Tired Light' ? |
|
| |
Yip... stated in terms of infomation theory rather than entropy(/fatigue). It seems I have a much firmer grip on it this way... |
|
| |
I would think that you would see significant shiftage between stars that are 10 times, 100 times and 1000 times further away. specifically that that shift would be 10x. nope, next theory! |
|
| |
But isn't the redshift proportional to distance? |
|
| |
Also, our distance estimates are intimately intertwined with
redshift (via a rather dodgy "standard candle"). |
|
| |
So, no need to throw out the theory yet. Also, I agree with
[madness] that throwing in information theory (=entropy)
might be a nice idea. |
|
| |
Re. Biglseep's link (and therefore slightly off topic) - isn't
that experiment just describing temporal diffraction? This
comes up every few years, and always turns out to be less
exciting than it first seems. |
|
| |
Ummm. Ignore. Just doing some background reading on speed of light slowing down and speeding up and liked the catchy line. |
|
| |
//All that needs to be shown is that high frequency waves carry more information than low frequency waves (and that is clearly the case)// |
|
| |
I have my doubts. The energy of a photon is proportional to its frequency, so for a given amount of energy you get a lot more photons if they are low frequency. |
|
| |
redshift relatively solid at distance, distorted by speed. Space probe data pretty conclusive at this point. Does not change with the distance to planets in our solar system but the shift does occur as their relative speed changes (as it does constantly). |
|
| |
If you compare the information carrying capacity of a single photon of blue light to that of a single photon of red light, I doubt your hypothesis will hold. |
|
| |
I guess it's hot in here because everyone's doing a lot of hand waving! :D |
|
| |
Humanzee, that is a remarkably astute question. |
|
| |
I believe that what we have come to believe is that if you are moving at the speed of light you don't get old. Are we tossing the old model out? |
|
| |
// The energy of a photon is proportional to its frequency, so for a given amount of energy you get a lot more photons if they are low frequency.// |
|
| |
That's nice... since for a single photon to experience field free attentuation it has to have an internal energy to dissipate (and the internal energy must be exhibited by its frequency). |
|
| |
... only as I understand it having observed a single photon all wave characteristics collapse... |
|
| |
Anyway as far as Jim is concerned it is all about jelly - each photon being one with attenuating wobble... |
|
| |
There is no difference. A photon can interact with matter, and therefore has observer status. |
|
| |
Was thinking about this --- and figure that the internal energy must dissipate as heat (which is pretty much the standard explanation for any isolated system). If you like it is the transfer of macro state to micro energy (and at lower macro state). |
|
| |
To take the example Jim gave above, the wobbling jelly will cease to wobble once its temperature has risen... |
|
| |
//information must be lost in transmission// |
|
| |
There is no information in a sine wave. (Or, at least, no more information in one sine wave than any other.) |
