|
| When talking about space-time, similar units must somehow be choosen

| only two meanings of the units in practice:
|
| * To indicate if we are talking about time (or time-like) or space
| (space-like). The right units makes it intuitive to the reader what the
| quantity is.
|
| * The scaling of the units. A reasonable range must be choosen. For
| example for length we have 'meters' in daily life. But if we would like
| to discuss things like atomic physics, then the scale Ångstrøm (1 Å
| = 10^-10 m) would probably be better. It's just like this.
|
| The idea is, that both meter and seconds can be used in space-time
| after one's own choice. Only the need to inform the reader about the
| meaning, and the choice of units on a relevant scale, are needed to
| make the choice.
|
| In this model, the speed-of-light is simply c = 1 (without any units).
|
| This is the advantage of these units described. It's basically the same
| as in most litterature in relativity, where 'c=1' is assumed, and
| similar units for space and time are usually used.
|
| So here: 1 s = 299,792,458 m in 'space-time length'. Choose meter or
| second as it would be best: The symbolic meaning and the best
| unit-scale.
|
| What's the opinion on this way of thinking?
| (IMHO it's working very well...)

Yes there is.
c = 0/0.

Einstein's straw man is:
"the velocity of light in our theory plays the part, physically, of an
infinitely great velocity."

Mel Gibson played the part, physically, of William Wallace in "Braveheart",
but
physics is not about playing parts in theories.

You don't have a mathematics background, you are a shithead.
Anyone with a mathematics background would KNOW c = 0/0.
