The discussion centers on whether time flows for a photon, with the equation Δt=γ Δt' suggesting that time for a photon (Δt') should be zero as γ approaches infinity when velocity approaches the speed of light (c). One participant argues that if time "shrinks to zero," it implies that time does not flow for a photon, while another clarifies that discussing limits in mathematics means approaching a value without actually reaching it. The conversation also touches on the concept of distance, questioning if it shrinks to zero or if it suggests that photons appear to "freeze" in motion. Ultimately, the nuances of relativistic physics complicate the interpretation of time and distance at the speed of light. Understanding these concepts requires careful consideration of mathematical limits and their implications in physics.

Hi everybody]Since we see light, from the equation Δt=γ Δt' , Δt' (the Δtime in a photon) should be zero, cause γ→+∞ for v→c and Δt is a descrete number (if we actually see photons). So, I thought the time in a photon doesn't flow, but my Physic friend said it's wrong..? In the frequently asked question, it's written that the time "shrinks to zero", isn't that the same to say it doesn't flow in a photon?
Also, there's written that the distance shrinks to zero, but isn't suppose Δs'→+∞ ? Otherwise, for Δs=Δs' / γ , wouldn't we see the photons like "freeze", like not moving??
* γ = 1/ √(1-v^2 /c^2)
thanks for the answers...and sorry if I'm not approaching this in a very "elegant" way (i'm doing engineering XD

You're only quoting a very small portion of the FAQ and thus taking it out of context. Do you understand that when mathematicians speak of a limit, they mean something that you can approach to as closely as you want, but you're not allowed to actually get to? So the FAQ is saying that it's meaningless to talk about what happens when you get to the limit because you can't get there.
 
In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
