What's the meaning of "tautology" ?
I could tell you or not tell you, personally.
There: you've seen both types
against maths; define time seems to alwwas need time to define it.
but if keep simple stupid (KISS)
it make sense to allow an equation does make sens as it s describe in a very much way what's happen against my right yes (i m lossing it).
EDIT : my right eye
as i know (maybe i m wrong)
we are travel at the speed not of light, but the one of causality (not ie spritual way.. just maths)
in fact light seems to be the one wo do as this speed... agasaint mass.
for light the time is not the same....
from you light from sun takes like 8m30s to be were.
bot for light... not same speeed .. is like quite .. NO TIME.
unbelivable but it s maths and..
it seems to describe weel how world works. but with this purpose too : the domain of a function > in couple of time someone will say taht more or less spessfic rules descibes mor much well the world.
EDIT: sorry for my bad english.
