From: OsherD on
Two recent papers in arXiv have gone in the opposite directions
almost, one finding a superluminal flare in the Central Black Hole of
our galaxy, the second claiming that a superluminal geometry would be
"unstable".

Here are some key points in favor of Superluminal Speed.

1. Theories and claimed "Laws" in physics ARE subject to contradiction
if they propose contradictory claims, and they ARE implausible if they
appear to lead to contradictions.

2. "No Superluminal Speed" contradicts Inflation as Geometric
Superluminality.

3. "No Material Superluminal Speed But Yes Geometric Superluminal
Speed" is implausible and arguably leads to contradictions.

4. If the Universe's Geometry Inflated Superluminally, then a reversal
of Inflation (Superluminal Contraction) or a partial reversal
(stopping before reaching minute size of the Universe) would place
material objects such as stars or galaxies within close proximity,
which is roughly equivalent to Material Superluminality in its
effects. This is because distant material objects would suddenly
find themselves near each other.

5. The beta or gamma factor or its inverse which allegedly precludes
Superluminality in Special Relativity, sqrt(1 - v^2/c^2), changes
SCALE from real to imaginary as v^2 changes from < c^2 to > c^2, as
argued in my previous posts in this thread. This was more or less
argued also by Sir Arthur Stanley Eddington in "The Mathematical
Theory of Relativity," Cambridge University Press: Cambridge U.K.
1922, 1948, etc. Eddington wrote the first book on Relativity
(Einstein and collaborators wrote the first papers on Relativity) and
did the eclipse experiments on GR. This makes "No Superluminal Speed"
implausible and arguably contradictory. There is no reason why the
sqrt(1 - v^2/c^2) precludes both subluminal (and luminal) and
superluminal regimes other than their not being in comunication, and
the latter (no communication) is even arguably wrong in view of modern
knowledge of phase transitions and limitations of mathematical models
at "extremes".

6. Subluminal and Luminal (light speed) experiments arguably cannot
DISPROVE Superluminality without using electromagnetic waves which
have Luminal speed, which is implausible and arguably
contradictory. Arguably, Superluminal speed objects or entities
would have their own Superluminal waves, which should then be used to
measure their speeds, but if this occurred, then it would contradict
the absence of Superluminality!

7. Wave Front Superluminality, which has been confirmed, is an
additional type of Superluminality to Inflation, and a similar
argument to 3 above holds.

8. The alleged Instability of known Superluminal Spacecraft geometries
(such as Alcubierre's, Lobos' , etc.) is reminiscent of the Wormhole
arguments, which have been currently won by the pro-Wormhole
researchers in arXiv. This raises a strong possibility of
implausibility.

9. The deepest Logical-related Physics theory, Probable Causation/
Influence (PI), which is an analog of Lukaciewicz/Rational Pavelka
Multivalued Logics, has no limitation against Superluminality and in
fact its least upper bound on all variables, 1, represents in general
INFINITY, unless it is a phase transition. Thus, light speed is
either limited by a phase transition (to superluminality) or is
infinite.

10. The absence of Human Scale Physics (HSP) DETECTION of
Superluminality can no longer be regarded as an example of Einstein
"Principle of Verification," since there are several known cases now
which contradict this latter idea, including Randall-Sundrum and
Kaluza Klein type higher dimensions, Superstring and Supersymmetric
higher dimensions, Abbott's Flatland example (regarded as a "Thought
Experiment" regarding erroneous conclusions in lower dimensions),
etc.
