Nevertheless, quantum mechanics
suggest that superluminal communication exist. In fact, there are hypothesis on
the obligatory existence of superluminal phenomena on nature [3, 4]. The
EPR-Bell paradox is the most famous example. Pondering about this paradox,
Smarandache again suggested in 1993, in a lecture in Brazil, that there is no
such thing as a limit speed on the universe, as postulated by Einstein [5]. It
appears that recently this paradox was completely solved by L. E. Szabó [6].
Even so, there are still many more evidences of the infinite speed — or simply
instantaneous communication — in the universe, as we shall see briefly.
Studying
solutions of Maxwell and Dirac-Weyl equations, Waldyr Rodrigues Jr. and José
Maiorino were able to propose a full-unified theory for constructions of
arbitrary speeds in nature (for arbitrary they meant ) in 1996 [7]. They also proposed that there is no
such thing as a limit speed in the universe, so that Smarandache Hypothesis can
be promoted to theory, as Smarandache-Rodrigues-Maiorino (SRM) theory.
What is unique
about Rodrigues-Maiorino theory is that special relativity principle suffers a
breakdown, however, even relativistic constructions of quantum mechanics, such
as Dirac equation, agree completely with superluminal phenomena. Also,
according to Rodrigues-Maiorino theory, even well positioned mirrors can
accelerate an electromagnetic wave to velocities greater of the light. This
assumption was later on confirmed by Saari and Reivelt (1997) [8], who produced
a X-wave (named this way by Lu, J. Y., a Rodrigues' contributor) using a xenon
lamp intercepted with a set of lens and orifices.
The SRM theory is a mathematical
pure and strong solution of the relativistic quantum wave equation, indicating
that there is no speed limit in the universe, and therefore is the most
powerful theory today for construction of arbitrary speeds.
In the case of
Nimtz experiment is not clear if it violates the casual paradox. On the other
hand, L. J. Wang, A. Kuzmich and A. Dogariu recently published an outstanding
result of an anomalous dispersion experiment where a light pulse was
accelerated to times
the speed of light, not violating the casual paradox, thus resulting in a time
travel! In practice, this means that a light pulse propagating
through the atomic vapour cell appears at the exit side so much earlier than if
it had propagated the same distance in a vacuum that the peak of the pulse
appears to leave the cell before entering it [10].
Van Flandern
data was later on explained with a theory that does not need superluminal
phenomena by Ibison, Puthoff and S. R. Little [13]. Yet, observations of
superluminal signaling from galaxies remains unexplained from subluminal point
of view.
Tachyons were
already, in an obscure manner, detected in air showers from cosmic rays [2].
Perhaps we would be able, in a
distant future, to send messages to the past or to the future. Anyway,
superluminal phenomena would have a more stand-on-ground application with local
communication. According to Rodrigues-Maiorino theory, the X-wave is closed
in a way that it does not loss energy as it travels. So, a superluminal X-wave
radio message would achieve its destination almost in the same condition as
when it were sent and no one, except the destination, could spy the content of
the message. The invention of such superluminal-signaling transmitter would be
of great power associated with MIT's pastille able to curve light in 90ş, in
the manufacturing of optic fibers.
