You say to jjw
You posted:
"We recite that light travels at about 186,281 miles per second because that is what we measure in this solar system."

You then offer:
"Miles/second is distance/time - a property
of 'space/time` not 'space`. - Same admonition."

Is that supposed to be some mathematical or physics demonstration of WHY light travels at 186,218 Mps. Pleas show the formula that provides that result based on the sun's mechanics or the physical nature of photons that result in that speed. Your " admonition " is misdirected and of no value to me. Thanks anyway.
