An immortal fumble by Androcles (Dastardly Fiend) (3-Dec-2005)

There is a coordinate 5 hours ago.

Right.

In your imagination only. I'm discussing physics, not your dreams.

How you can mistake yesterday from tomorow is beyond me.
I think you are fucking crazy.

There is a coordinate 5 hours ago.There is no vector to take you there.
You ARE fucking crazy.

Physics. This is physics. We use mathematics to DESCRIBE physics.
We do not invent extra dimensions in physics. We do not invent vectors
where none exist.
You ARE fucking crazy.

That's what  I said.  You confuse vectors with coordinates.
You are fucking crazy.

If
  tau = (t-vx/c^2)/sqrt(1-v^2/c^2)
  xi = (x-vt)/sqrt(1-v^2/c^2)

then it logically follows that

  tau = (t-uy/c^2)/sqrt(1-u^2/c^2)
  eta = (y-ut)/sqrt(1-y^2/c^2)

and

  tau = (t-wz/c^2)/sqrt(1-w^2/c^2)
  zeta = (z-wt)/sqrt(1-w^2/c^2).

You now have more relative time than you can handle.
You are fucking crazy.  Fruitcakes, the lot of you.
Dumb, stooopid, idiotic morons, you all belong in an asylum where
the sane will be safe from you, and all because some huckster thought
he knew any math and made up his own definition of time.
If you are going to use math to describe physics, use it properly.
Learn the basics.

You are BLIND, Poe, and a mental cripple as well.
Every bit as stooopid as the aetherialists. Phuckwits. Like sheep,
you follow each other around, walk in each others shit and think
it's green grass.
Gravity is caused by curved nothing? Baahhhhh, baahhhhh, baahhhhh,
Einstein, bahhhhh,baaaahhhhh, bahhhh, Lorentz, bahhhh, bahhh.

Sheep. Give the youngsters a chance, you stupid old cunt, and fuck off
and die. Your pathetic mentality is insanity and isn't an asset to anyone.
 Androcles.
