Speed of light, again.. with a twist

[bojan]

This is about speed of light but slower... depending on photon energy, and perhaps a first glint of quantum gravity.

Nice one Bojan, this is very interesting stuff. For those interested in more of the nitty gritty, follow the link to the preprint and then to the PDF.

I wonder if the assumption that the low and high energy photons are indeed emitted at the same time is a correct one...
If this emission is due to the black hole swallowing something, would it not be the correct to assume that the lower energy photons are created earlier, compared to high energy ones, simply because high energy photons are created when whatever went in the hole was more compressed (and therefore hotter) a bit later, just before reaching the event horizon?

I dont know how I missed this.. well I have been preoccupied.
So interesting. I read someplace last night light had been slowed in a lab (..and yet to buy any goods but a figure of 57 miles a second sticks in my head..I was tired so I cept reading it didnt dawn on me until this morning..dawn on me morning..oh sorry)..but I have been thinking about it most of this morning.

In my universe it all adds up of course.

I never thought light..C.. could vary much but if it could go so slow in the lab... well you all understand the implications better than me... but how exciting...

anyways I find 57 miles per second hard to accept but these folk in the link are not talking about such a slow up..the fact is any slow up by one side of the area of view coming to us will cause distortion of the image... so any variation even small will give distorted views I feel... I have believed as you all probably know that gravity is a manifestation of the push nature of particle radiation...its just that I cant show you the particle...
But if temprature has an effect (coupled with whatever ingredients were used in our yet to be verified lab experiment suggesting 57klm/sec) on light I say it is the effect that temp has on the overall particle flow for that region and in effect changing the pressure..the pressure which is in effect is our decription of gravity.

Another thought..if light follows the space time grid does not the dip to a mass in effect slow that part relative to say another part of the beam further away from the mass.. each beam may be the same speed but from an observers point of view the light coming from there would be the light close to the object would arrive later because in effect it had more space to travel accross..you know down the bend in and out again is longer than a sttraight line further out...

So in my universe the heavier paricles will arrive a little latter ..why wouldnt they? or do they..I better re read all of this there is too much flying around and not nailed down.

I am aware this may sound quite moronic,
but a recent episode of Futurama is brought to mind.
The Professor is explaining how his engines he invented can go at the speed of light.
An objection is raised , stating that nothing can go the speed of light.

The professor replies, of-course not , that's why they decreased the speed of light.

Interesting to read that argument, with such a comical reflection on it.

Yes I saw that episode.
Did you catch the... we stand still and move the Universe around the ship ...you know rather than the ship goes anywhere...

When you think about it even a small percentage variation in C could distort distant views...

I still haqve not looked at the 57 miles per sec to see if there is anything to it... the link was on another machine and I can not remember the site ..I will look later again... just seems far too slow... I should have taken more notice.
