How infinite does time get by gamma

How infinite does time get by gamma...

So I was thinking, say you have a photon traveling at c. I would assume that the photon's own time frame would have time passing as normal. Now after a time t has passed in the photon's frame, some infinite amount of time would have passed say, on Earth by the time dilation equations, but that seemed a bit strange, from the light's point of view anyways, what would it "see" after a second or whatever in its own time? The universe come and gone? >.<

Then I thought about assigning different alephs to the set of time intervals traversed, but meh I'm now more confused that before. Help please! ;-)

Hi zZhang!

A photon could measure time and distance using its own wavelength as a "measuring-rod", I suppose.

So a photon can only really compare its own measurements with another photon's.

Comparing its own measurements with those of a slower-than-light observer doesn't make any more sense than trying to project something onto a screen when the angle of the screen to you is 0º - the ratios become infinite!

Yea that was the thing, that it didn't make any sense. Is there just no sense of time in the photon's frame?

Be a photon!

Well, as I said, the photon could measure time by using its wavelength - it should certainly be able to compare the lengths of different objects that way, and also to compare the wavelengths of other photons!

But unless you're thinking of becoming a photon yourself …
