Ok, I have a limited physics background. I have just enough knowledge
of relativity to be dangerous! A couple of questions from a simpleton
concerning the speed of light:
1. Why is the speed of light 300E6 m/s? Why isn't it a tenth that
speed? Why isn't it ten times that speed?
2. Since the speed of light is finite, what is there in a vacuum that
limits its speed? If a vacuum is truly empty as we classically think
of 'empty', shouldn't the speed of light in a vacuum be infinite? What
holds it back?

The speed of light isn't "finite." It's constant, c . . . or infinite
redux. As to the argument about c equaling 1, the "Uni-" in Universe, as
well as in "universal," and as well in "Unity," linguistically, also
logically, philosophically, physically and mathematically translates to 1
('one' = 'uno'). Pardon the pun but an infinite Universe is an infinite one.
Its constants are its own 'redux'. They are NOT "finite." Finite, as in
"finite velocity," is relative.
Light's speed of emission is instantaneous . . . in zero time . . .
exactly as Einstein imagined "time" to be "at the speed of light."
'Why can't anything travel faster than the speed of light?' Because all
arrows of time point the other way as far as light's light time is
concerned. Travel into any light in any direction and you will travel
forward in time. Light time doesn't deal in any 'present', any 'now', except
at the exact instant, the exact moment, of emission. All otherwise it is a
matter of 'past' as far as time is concerned. When an emitted expansionary
light front is one light second from any source whatsover, that source is
one second passed, or one second out front of, that emitted time orientated
light front as far as time is concerned. To the source that light front is
no front end of time. It is the back end of time and everything oncoming
toward the source will always have to travel [at whatever velocity] back end
of time (light fronts) to front end of time (present locations and states of
sources) as if they were traveling from some big bang horizon to, or toward,
Earth 'now' in time. They (whatever they are) will overtake time but never
overtake light or the speed of light.
A light front being single-sided, there is also no such thing as turning
around into it either. Every turn into a light front is a turn into a
different light front (a different back end of time). A light front always
being the back end of time, there is no possible way any traveler, period,
at any velocity whatsoever can ever beat it to any front end of time 'now'
sources. Each stage of light front traveled will always be a later stage in
and of time on the way to time's 'now' sources. So as an arrow 'head' of
time, the front end of time, has the ultimate advantage of having already
beaten any and all travelers to any and all sources of light emissions of
light fronts. Each race is a laugher. No traveler is ever in the race at any
time. The Universe has fixed the race before any traveler ever gets into any
starting gate, much less out of it. It cheats.
