The ultimate thread about photons (questioning the basics)

No, not actual movement. It's how quickly the electromagnetic field switches back and forth as you watch the wave go by.

Afterburner, may I ask where you got the number for "neutron oscillation frequency"?

[afterburner]

ngeo, i believe it was from this paper.

Thank you afterburner, that is an interesting link. I see it is being aired on the ATM forum.

That is correct ngeo
dont mean to resurrect this thread, but i thought these questions fit here (they are photon-related)

When a photon slows down becasue its moving through a non vacuum, do other photons(that ARE moving through a vacuum) pass it at the speed of light? or by the amount that the original photon slowed down?

In the Big Bang theory, space-time was born at the moment of the "explosion", and began expanding. Im assuming that lots of photons were "born" at this moment or not much after the explosion. Is this corect?
Assuming the BB happened 13.5 billion ears ago, the diameter of the universe should be 13.5 billion light years. Is this a correct assumption?
Now, assuming that the volume WAS expanded by these photons, or other similar particles (i dont know if thats what the theory says, thats why im only assuming) then does that mean that the "space" in between photons/particles was aslo "filled in"? Let me rephrase

if we assume that singularity was the "center", and all things moving away from this "center" at he speed of light are what expanded sace, would the areas in between these paticles be considered space awwell, even though nothing was present there yet? You see what i mean? or did scientists say that since "these two" particles are "this far away" at "this time" everything in between MUST be space aswell. (by the way, right now i have a mental image of a sea urchin as a universe)

Thanks
