The classical ether-drift experiments: a modern re-interpretation

TL;DR

This paper reinterprets classical ether-drift experiments suggesting they may indicate a preferred frame related to cosmic motion, challenging the traditional null results interpretation and proposing a stochastic vacuum model.

Contribution

It offers a new analysis of ether-drift data linking observed effects to Earth's motion and a turbulent vacuum model, questioning the standard relativistic null result conclusion.

Findings

Re-analysis of Joos experiment shows effects consistent with Earth's motion at 300 km/s.

Data irregularities suggest a turbulent vacuum medium rather than instrumental artifacts.

Supports a stochastic vacuum model aligned with quantum physics and relativity.

Abstract

The condensation of elementary quanta and their macroscopic occupation of the same quantum state, say k=0 in some reference frame Sigma, is the essential ingredient of the degenerate vacuum of present-day elementary particle physics. This represents a sort of `quantum ether' which characterizes the physically realized form of relativity and could play the role of preferred reference frame in a modern re-formulation of the Lorentzian approach. In spite of this, the so called `null results' of the classical ether-drift experiments, traditionally interpreted as confirmations of Special Relativity, have so deeply influenced scientific thought as to prevent a critical discussion on the real reasons underlying its alleged supremacy. In this paper, we argue that this traditional null interpretation is far from obvious. In fact, by using Lorentz transformations to connect the Earth's frame to Sigma, the small observed effects point to an average Earth's velocity of about 300 km/s, as in most cosmic motions. A common feature is the irregular behaviour of the data. While this has motivated, so far, their standard interpretation as instrumental artifacts, our new re-analysis of the very accurate Joos experiment gives clear indications for the type of Earth's motion associated with the CMB anisotropy and leaves little space for this traditional interpretation. The new explanation requires instead a view of the vacuum as a stochastic medium, similar to a fluid in a turbulent state of motion, in agreement with basic foundational aspects of both quantum physics and relativity. The overall consistency of this picture with the present experiments with vacuum optical resonators and the need for a new generation of dedicated ether-drift experiments are also emphasized.
