Proposal for an experiment to test the simultaneity theorem of the special theory of relativity

Reinhold Fürth

Published Jan 1, 1965• 5 citations
Publisher

Abstract

e indirect evidence for the existence of the Lorentz `local time' effect, which is also a feature of the special theory of relativity, is discussed and a fairly simple direct experiment, using radio waves in the centimetre region, for testing the theorem of the relativity of simultaneity of events is proposed.

II. Discussion of an experiment proposed for testing the simultaneity theorem of the special theory of relativity

J.L. Rodda

Recently Fürth proposed an experiment to test the theorem of the relativity of simultaneity of events. Using this theorem he shows that the proposed experiment will result in a measurable phase shift. He neglects, however, the Lorentz transformation for spatial coordinates, and it is shown here that when this transformation is included the phase shift will actually be zero.

Comment on a paper by R. F rth, `Proposal for an experiment to test the simultaneity theorem of the special theory of relativity'

J.R. Wormald

In a recent paper Fürth has proposed an experiment in which he predicts that a positive result of first order in v/c will be observed, caused by the difference in local time of two observers in uniform relative motion. It is shown that, if the special theory is correct, the phenomenon predicted by Fürth would not be observed.

Conclusions About the Simultaneity of Two Events

Vesselin Noninski

A 'gedanken' experiment is presented whereby two simultaneous events (from the point of view of an obesrver in a train) trigger an explosion which destroys a train. A stationary observer using the Special Theory of Relativity (STR) to determine simultaneity in the train concludes that no simultaneous events have occurred on the train, hence the train is intact. It is pointed out that the conclusion the stationary observer makes is incorrect because it is based on STR as a method to determine simultaneity.

The Special Theory of Relativity and the Unreality of the Future

Michael Tooley

Abstract According to the Special Theory of Relativity, there is no such thing as absolute simultaneity, contrary to the view defended in the book. However, this chapter demonstrates that the Special Theory of Relativity can be modified so as to allow absolute simultaneity. This modification involves reference to absolute space and the causal relations between space‐time points, and drops the assumption that the one‐way speed of light is constant through all frames of reference. Contrary to the orthodox theory, the modified version has the additional advantage of avoiding a clash with quantum mechanics, such as brought out by the Einstein‐Podolsky‐Rosen thought experiment and Bell's Theorem.

Quantum Tests of the Foundations of General Relativity

Cláus Lämmerzahl

A new test theory for describing tests of fundamental principles of Special and General Relativity is presented. Using a generalised Pauli equation which may be based on a generalised Dirac equation, possible violations of local Lorentz invariance and local position invariance on the quantum level are described. On the quantum level there are more possibilities to violate these principles than on the classical level. The corresponding terms can be tested by Hughes–Drever type experiments or by atom interferometry. It is proposed that an atom interferometric test of Local Position Invariance will give a three order improvement of existing estimates. 1
