A Discussion of Special Relativity
Galina Weinstein
TL;DR
This paper discusses key conceptual issues in special relativity, including the non-existence of rigid bodies, the definition of simultaneity, and alternative formulations without light, challenging some traditional assumptions.
Contribution
It offers a critical analysis of foundational concepts in special relativity, proposing alternative perspectives and clarifications on synchronization and velocity composition.
Findings
Rigid bodies do not exist in special relativity
Distant simultaneity can be defined without synchronized clocks
Relativity can be formulated without relying on light signals
Abstract
Five topics: A rigid body does not exist in the special theory of relativity; distant simultaneity defined with respect to a given frame of reference without any reference to synchronized clocks; challenges on Einstein's connection of synchronization and contraction; a theory of relativity without light, composition of relative velocities and space of relative velocities.
