If there is no distance to the photon's destination, then why does the photon notice that surrounding clocks have advanced while it was in flight? Double-A

Hi Sam. It is nice to see that you have begun to be more friendly of the instantaneous idea- that photon- when treated as particles do begin to demonstrate instantaneous measurability. When we think of the work of Max Born and the physics of the double-slit experiment we automatically begin to measure the limit of the instrument - I think that we are technically beyond this- yet still do not know the knowledge of what the information provides.

There is nothing instantaneous in this universe, Gogo. Everything, even earth hurled at two gigantic slits has wave-like properties.

It's creatures like us (i.e. made of matter) who do experience time and distance who notice its time and distance. Yousuf Khan
