Ok, I have just now had a rare Eureka moment in connection with the quandary described in the above post!
Dripping wet, I pull on a pair of pants (this time) and, finding no one on the street who cares, return home to at least document it on Word Press:
The problem of Simultaneity, alias “so what time is it ‘really‘ on the Sun right now?” is a simple result of common sense extrapolating into the un-extrapolate-able zone, so to speak.
If we remember the scene above of the poor fellow hammering stakes into the ground on a far-away hill, and the sounds of his hammer-hits being delayed as seen by us the observers, we have no real problem with that. Anymore than we have with thunder following lightning by quite a few seconds. Sound is kinda sluggish, as velocities go these days. And light being faster, indeed ‘instant’ for all practical purposes on the Earth’s surface, we assume that the post-driver we see with ‘our own lyin’ eyes’ is ‘doing-it’ in ‘real time’.
But then Light was discovered to have a finite speed itself. Ugh. The timing of Jupiter’s moons appears to ‘advance’ as the big planet gets closer to the Earth in its travels, among other early hints.
“No problem” we say, “‘what we see is ‘what happened around Jupiter an hour or so ago’.” A simple repeat of the ‘speed-of-sound’ workaround. Everybody’s happy…
Until… ‘A punch in the gut this way comes!’. Maybe from a black hole?
Yes indeed, from a black hole, (or, as they prefer to be called ‘a differently-pigmented hole’)
Hard to say anything nice about a black hole. In fact you can’t (or ‘aren’t allowed‘ to say much at all about ’em. Ha, forget about what’s up over (down? ) there this Tuesday afternoon August 15th 2017. Deep inside the ‘nothingness we ‘see’, other than a froth of doomed matter circling the drain awaiting ‘nothing-i-zation’, well, Time and Space have stopped being and happening.
“Because-a why?” we protest.
“Well”, say the dancing wu-li physicists, “because even information is crushed inside the singularity.” It don’t matter how we feel about it, there no longer any ‘there‘ there. A cosmic ‘nothing-burger, no ketchup, no fries’.
Ok, fighting for naive realism and common sense, I grudgingly agree, but make an exception, un-wisely, for my ‘I still say it moves‘ view of the Sun:
“We’ll know what’s happening on the Sun ‘now’ in about eight minutes”, I declaim. *looks at watch*
A deafening buzzer sounds! I am led out of the Academy of Modern Physics in shackles.
‘About what you cannot know, nothing must be said’, I speed-read the wall-hanging on my way to the paddy-wagon.
“Somewhere in Pennsylvania at this very moment, doves are mourning my incarceration”, I console myself from my cell.
The Warden, a lascivious smirk on his repulsive face, bursts my ‘common sense’ bubble with diabolic glee:
“Sorry, sucka, my brother-in-law shot ’em all a half a second ago!”
