Causality Effects of Particles That Travel Faster Than Light

Abstract

This paper comments on a recent paper by Feinberg and describes an experiment in which an effect would precede its cause if there were particles that travel faster than light.Received 11 April 1967DOI:https://doi.org/10.1103/PhysRev.162.1274©1967 American Physical Society

Beyond the speed of light

One of the most fundamental laws in physics is that nothing can travel faster than the speed of light. However, two teams of researchers have now shown experimentally that electromagnetic pulses can be made to travel faster than c, the velocity of light in vacuum, and over relatively long distances.

Critical Remark on the Observability of the Sign Change of Spinors under 2π Rotations

Gerhard C. Hegerfeldt, K. Kraus

In a recent paper, Aharonov and Susskind claimed rotations by 2π to have observable effects on spinors. Their reasoning is shown to be inconclusive.Received 21 September 1967DOI:https://doi.org/10.1103/PhysRev.170.1185©1968 American Physical Society

Can Quantum Nonlocality be the Consequence of Faster-Than-Light Interactions?

Luiz Carlos Ryff

It has been advocated by Bell and Bohm that the Einstein-Podolsky-Rosen (EPR) correlations are mediated through faster-than-light (FTL) interactions. In a previous paper a way to avoid causal paradoxes derived from this FTL hypothesis (via the breakdown of Lorentz symmetry) has been suggested. Lorentz transformations would remain valid, but there would be no equivalence between active and passive Lorentz transformations in the case of EPR correlations. Some counterintuitive consequences of this assumption are briefly examined here.
