If when you're moving at the speed of light time freezes, why then does it take light 8 minutes to reach the Earth from the sun?
Do you think maybe it's because you're not moving at the speed of light?eyad-996 said:If when you're moving at the speed of light time freezes, why then does it take light 8 minutes to reach the Earth from the sun?
How could that possibly be relevant?eyad-996 said:Pauli's exclusion principal?

Not that I am aware of.ThereIam said:One might still ask, DO we have a theory that suggests the meaning of time for a photon?

Your question started:eyad-996 said:What do you mean?
But you're not moving at the speed of light. You are stationary. The light is moving at the speed of light.If when you're moving at the speed of light...
eyad-996 said:I'm not talking about me moving at the speed of light, I'm talking about light itself! Light is moving at the speed of light (obviously!) Shouldn't time freeze for light and arrive instantly - since time has stopped for it!?
pervect said:The geometry of light has an affine nature - it doesn't have measurable "time intervals" at all. We can order A, B, and C, but we can't assign any meaningful numerical intervals to the "distance" between them.
eyad-996 said:You've been a great help, but from the last paragraph I only understood that time doesn't have measurable time intervals! But why?
Here's a thread you should read:Moonraker said:What about this answer:
The time dilation formula is according to http://en.wikipedia.org/wiki/Time_dilation
T‘ = T * sqrt (1-v2/c2).
Set v=c, the proper time of light T’ will always be 0. The lorentz transformation is not defined for the speed of light, but the time dilation formula above is.
However, time is not frozen, the proper life time of a photon is zero.

bcrowell said:(3) If when you're moving close to the speed of light time freezes, does that mean that only a very short time passes in the frame of a neutrino that, in the Earth's frane, takes 8 minutes to reach the earth?
The answer would be yes.
It was no mistake.Moonraker said:Hi ghwellsjr,ghwellsjr said:
which one? are you (mistakenly?) referring to our current thread?
Moonraker
So then why do you say:pervect said:You have some a notion of time, and you assume that light must have some sense of it too. And this idea is wrong.
This is a wrong statement because time does not apply to a photon. It doesn't have a proper time or a life time or a proper life time or any other time. You shouldn't say that time for a photon is not frozen or frozen. You should say time doesn't apply to a photon which is different than saying that some kind of time of a photon is zero.Moonraker said:However, time is not frozen, the proper life time of a photon is zero.

These are not times measured from the (nonexistent) frame of a photon, they are measured from other quite ordinary frames of reference.Moonraker said:I don’t agree. There is no doubt that each photon is sent and absorbed at a precise time.Temission and Tabsorption. Time applies to photons too.
The neutrinos speed in the neutrinos frame is 0.Moonraker said:I suppose that neutrino's speed in neutrino's frame is not higher than light speed because the distance sun-earth is diminishing in neutrino's frame as well? (according to Lorentz transformation)
Doc Al said:These are not times measured from the (nonexistent) frame of a photon, they are measured from other quite ordinary frames of reference.
DaleSpam said:The neutrinos speed in the neutrinos frame is 0.
You do realize that the time dilation formula is just a special case of the Lorentz transformation, don't you? So if the LT doesn't apply, neither does the time dilation formula.Moonraker said:No, the moment of emission is the same for the observer and for the photon.
At the absorption, the clock of the observer shows 8 minutes (Sun-Earth). The “clock” of the photon shows 0 seconds, according to the above-mentioned time dilation formula:
T‘ = T * sqrt (1-v2/c2),
even if the Lorentz transformation does not apply to photons.
The distance the neutrino travels is indeed 0 in the Neutrinos frame. Note that that is not the same as the distance between the Earth and the sun.Moonraker said:This would mean that the distance is 0 as well in the neutrino's frame.
