Why is the speed of light the value it is?

All indications of relativity point to there not being a frame of reference for a photon.
That why i hyphenated it.

''frame of reference''
What hyphens?

OFGS - My fault.. not hyphenate. The last thing i want to do is confuse this thread anymore. Sorry.

Thank you Sadarian.

I am glad that you are paying attention. The rest of these twits would not appreciate humour even if it was a kipper smacking them in the face.

Thank you. This is tantamount to decaring that a photon's velocity is infinite.
Did you read my post (of the 05.12.2009)?

Why didn't you just say "today"? Oh, maybe you mean May? I'm sure I did, and it probably points out that I don't know what I'm talking about, which may well be correct.  :D

Nope, nothing relevant in May, so it must be the one in this thread that says photons have no frame of reference. I would not argue with that. I saw your post, but I was too busy jousting with Mr S to respond.

My comments about infinite speed should be taken with a large grain of salt. However, I do believe we still have a lot to learn about photons.

To be fair, nost people only apreciate that sort of humour when it's someone else's face getting smacked.

Geezer, take a look here.
http://www.physicsforums.com/archive/index.php/t-209191.html

But it's difficult discussing a 'time frame' when relativity flatly states that there are none, as seen from a photon. That's one of the reasons why I tend to look at them as not 'traveling' at all.

http://en.wikipedia.org/wiki/Virtual_particle#Virtual_particles_in_Feynman_diagrams

As for Wheeler–Feynman absorber theory

The Wheeler-Feynman model, called the "absorber theory of radiation," makes electromagnetism a two-way street as far as the time dimension is concerned. They based their time-symmetric theory on the assumption that every light wave emitted by an atom must be absorbed by another atom and that these two events, light emission plus light absorption, should be considered as a single inseparable process. In it they see ‘time’ as going backward from the sink (your eye), which is cases allowed by both Dirac's equation and Maxwell's wave equation for light, as well as it goes forward in time from the source (sun). As a result any light observed will need both factors to exist (Source and sink)

And some different interpretations of it.
