The case tau <> t leads to unphysical behaviour, so can be rejected,
fuckhead.

"Thence we conclude that a balance-clock at the equator must go more
slowly,
by a very small amount, than a precisely similar clock situated at one of
the poles
under otherwise identical conditions."

Thence we conclude Einstein was a fuckhead, just like Vickson.
