Does light age?  Does it get older?

[Soul Surfer]

No.   light and all electromagnetic radiation is totally unaware of time because it travels at the velocity of light.

[yamo (OP)]

Does it age when it is slowed (bose einstein condensate), or is it still going the speed of light even if the speed of light is much less than c.

[yor_on]

Yamo, does the light age more the more light years we know it to come from?
If you think it doesn't, why would it matter to it that we have stopped its 'motion'?

[Ron Hughes]

Since we have no way to test if the wavelength of light gets longer over great distances we can't answer your question. Currently mainstream says the red shift is due to velocity of receding galaxies. Can they guarantee that? Could it possibly be a combination of both?

[PhysBang]

If it is a combination of both, then the amount that the wavelength of light changes over great distances must be really, really small. This is because there are a number of different ways to measure how light behaves over large distances and the relationship between expansion and light matches all of them to a great deal of accuracy and other hypotheses do not.

[Jessica.Amanda]

No my dear nerd.
Why do you think that light would age?

[Jessica.Amanda]

I think you mean to say that time period of existence of photons.
well is that what you meant, isn't it ?
