OK - so does that inform my question ? -= light travels at C and only ever travels at that speed, and cannot be stationary. Fair enough. I'm trying to finesse my Q. - is light "frozen" in time ? Does time have any meaning for a beam of light ?
Mmm. Yes I picked up on that point. With respect, LIGHT can travel at C, I kind of mean (in a just partly metaphysical way) what might it be "like" to be that beam of light ? What might the nature of it's experience be, if it had the capacity to observe it's surroundings ?
Trying to imagine what the world looks like traveling at relativistic speeds of course has a noble history, vis a vis Swiss trams etc. etc. I get the thing about passing clocks at speed and staying young by going really fast (and slowing down again). I apologise if this perhaps rather obvious...
