Nobody is stopping You to hit the focus: tell us, what You think, when
You talk
about "... 1 time axis perpendicular to x,y,z."

I'm afraid, we will not get an explanation from You. May be Time is
different from Space.
If i looked it up correct, then a 'pendiculum' is a balance of weights,
horizontal to earth-surface.
And 'perpendicular" thus means vertical, straight through the
horizontal balance. We can add
to these two directions, which are at a right angle to each other, the
axis of the balance, when it
balances or moves, again at a right angle to the two others.
No place for time left, unless You show us.It seems You cannot, so i've
got the impression,
that You are in connection with these people, who want to revive the
medivial obscure theory,
that the earth is not moving, to which we all know the famous reply: "
....and yet she moves!"
One can freeze movements, bring a balance to rest - but times...
they area achanging. I like this.
Thanks for Your comments.

Hero
