| Jul 15, 2014 at 14:25 | comment | added | KidElephant | The speed of light can only ever be approached. It doesn't really make sense to try to understand how a photon experiences the passage of time, because photons are integral to the way that time is defined. | |
| Jul 15, 2014 at 14:25 | comment | added | ACuriousMind♦ | Claim: There are no frames of reference where a photon is at rest (i.e. there are no frames travelling at the speed of light.) Proof: The speed of light is constant in all frames. In the hypothetical photon frame, the speed of the photon is 0, yet its speed is the speed of light. Contradiction Thus, there are no frames in which a photon is at rest. | |

| Jul 15, 2014 at 14:20 | comment | added | Derek Roberts | What do you mean that the frame of reference of the photon doesn't exist? Because the photon is not an 'observer'? | |
| Jul 15, 2014 at 14:16 | comment | added | fqq | Time dilation is a relative phenomenon, in your question you seem to ignore the notion of a frame of reference. Light travels at a speed, which is fixed in any frame of reference. The ``frame of reference'' of the photon doesn't exist. | |
