OK this looks like a good paper. Remember, the issue really is whether
the use of a singular point source Tuv is physically relevant. I say it
is not even though the mathematics of the solution may be correct! The
Einstein-Rosen bridge does not have that singular point Tuv RICCI
volume-changing (de)focusing source, on the contrary, it is pure Weyl
stretch-squeeze tidal astigmatic vacuum curvature. Note that zero point
dark energy is Ricci not Weyl! Weightless warp drive is zero point
energy induced Ricci curvature using both volume expansion and volume
compression as shown in Alcubierrie's toy model bubble metric. You can
use geometrical "optician" lens analogies here indeed mock up an analog
simulation with optical devices useful for practical flying saucer
"fighter" design studies.

Here is a very descriptive paper by Antoci and Liebscher containing a

OK, the real issue here is one of global topology and has nothing to do
with local algebra. BTW the infinite absolute rest LNIF 4-acceleration
is well-known and is even in Kip Thorne's popular "Black Holes and Time
Warps". |
