Gravity and Faster than Light Particles
In this paper, I discuss whether superluminal particles exist in the general relativistic theory of gravity. It seems that the answer to this question is negative. In truth, the result may only represent a difficulty to special but not general relativity, the later allowing both Lorentzian and Euclidian metrics. An Euclidian metric does not restrict speed. Although only the Lorentzian metric is...
متن کاملFaster than light?
The hypothesis formulated by Smarandache on the possibility that no barriers exist in the Universe for an object to travel at any speed is here shortly analyzed. In 1980, contrarily to what previously postulated by Einstein, Smarandache, according to the EPR paradox, formulated the hypothesis that no barriers exist in the Universe for an object (or particle or information or energy) to travel a...
متن کاملNo Faster-Than-Light Observers
We provide a formal proof within First Order Relativity Theory that no observer can travel faster than the speed of light. Originally reported by Stannett and Németi [1].
متن کاملFaster than Light Quantum Communication
Faster than light communication might be possible using the collapse of the quantum wave-function without any accompanying paradoxes.
متن کاملSlepian’s Faster-Than-Light Wave
where ω = vk and k± = k x̂ ± kΓ ŷ. Slepian also noted that if v < c, then cos(kΓy) = cosh(kΓ′y) where Γ′ = iΓ = √ 1− v2/c2, and the waveform (1) again propagates with speed v. The vector potential (1), together with scalar potential V = 0, satisfy the conditions for the Coulomb, Gibbs, Lorenz and velocity gauges. See, for example, [2]. For completeness, the electric field is E = iωA ≡ E+ + E− wh...
