the diff between
newtonian mechanics
and special relativity is not
as great as the conceptual gap
between the latter & general relativity
.
the key shift
from newtonian to
special relativistic mechanics
is abandonment of the independence
of time, subsumed in minkovski's spacetime
.
but the key shift
between special and general
relativity is the abandonment of the concept
of a constant spacetime. now it is dynamic, affected
by the very mass that inhabits it. it is not
so much a warping, but of
"removing" it from
consideration
.
of course
there's no free lunch
the continuum stress-energy
relations don't solve
themselves

physics disciplines thought experiments as poetry disciplines metaphors
but only logic has an inner discipline
