What is the space-time interval?
A metric, measured in meters.
It is mostly an abstract thing that is not very useful.
So we set ds²=dl²-c²t².
Why and for WHAT?
For nothing.
For fun.

What you write is not even wrong, it's gobbledygook. It's like saying
that Newton was wrong because he used vectors or Hamilton was
wrong because he used characteristics.

Hachel notation is much more practical,

Stop wasting your life on asinine fantasies. Face it: you
cannot do physics, it's not the end of the world. I cannot
play Beethoven sonatas. I survived.
