Summary
One of the most important theoretical consequences of the principle of relativity,i.e. the absence of transverse Lorentz-Fitzgorald contractions in moving bodies, has never been subjected to direct experimental tests. The existing indirect evidence of this absence is discussed, and a simple experiment for testing it directly and with high accuracy is proposed. Some implications of a possible nonnull result of this experiment are also pointed out.
Riassunto
Una delle più importanti conseguenze teoriche del principio di relatività, cioè l’assenza di contrazioni trasversali di Lorentz-Fitzgerald nei corpi in moto, non è mai stata sottoposta a verifiche sperimentali dirctte. Si discutono gli argomenti indiretti esistenti a favore di questa assenza e si propone un semplice esperimento per provarla direttamente e con grande precisione. Si indicano inoltre alcune implicazioni di un eventuale risultato non nullo dell’esperimento.
