Robert McEachern
AI Overview
Robert McEachern, a critic of mainstream physics, compares the problem with modern physics to the use of epicycles for explaining planetary motion to highlight what he sees as an overly complex and flawed mathematical framework that masks a misinterpretation of reality. The core of his argument is that like the ancient astronomers, modern physicists are adding layers of mathematical complexity to a theory that may be fundamentally incomplete, rather than accepting a more parsimonious explanation.
The analogy breaks down as follows:
The epicycle problem in astronomy
The Issue: The geocentric model of the universe held that the Earth was the center and all other celestial bodies revolved around it in perfect circles. However, this simple circular motion could not explain the observed retrograde motion of planets, where they appeared to move backward in the sky.
The "Solution": To make the model fit the observations, astronomers added "epicycles"—smaller circular orbits within the larger circular orbits of the planets. This made the model more complex but allowed it to successfully predict the planets' positions.
The Flaw: The epicycle solution was a mathematical fix for a flawed premise. It accurately described the observations but did not reflect the true nature of the solar system, which was discovered to be heliocentric with elliptical orbits.
The modern physics problem, according to McEachern
The Issue: The mathematical framework of quantum mechanics is incredibly successful at predicting the outcomes of experiments, but it contains paradoxical and counter-intuitive phenomena, such as superposition, entanglement, and the uncertainty principle.
The "Solution": Mainstream physics has accepted these strange phenomena as fundamental properties of reality. According to McEachern, physicists have "slapped-on" new, more complex interpretations and concepts (the epicycles) to explain these paradoxes, instead of reevaluating their core assumptions about what the mathematics describes.
The Flaw: McEachern argues that many quantum mysteries stem not from reality, but from a misinterpretation of the mathematics itself, particularly regarding the nature of information. He believes that quantum mechanics is an incomplete description, capturing only the statistical results of detection, not the underlying reality of particles or waves.
McEachern's information-centric alternative
Instead of resorting to complex and bizarre explanations for quantum phenomena, McEachern proposes a more parsimonious alternative rooted in information theory.
Reinterpreting the uncertainty principle: McEachern argues that the uncertainty principle is not a fundamental property of nature but a consequence of Shannon's Information Theory, specifically reflecting the minimum amount of information (one bit) that can be recovered from a measurement.
Explaining quantum correlations classically: He suggests that seemingly strange correlations in experiments like Bell tests can be explained by a classical, deterministic system based on how information is processed, rather than invoking non-locality or entanglement.
Focusing on observations, not reality: McEachern's comparison suggests that physicists are so focused on making the math of quantum mechanics work that they have mistaken their mathematical description of observations for a description of reality. This, he says, is the same intellectual trap that led astronomers to add more epicycles instead of questioning their geocentric premise.

Robert McEachern draws a comparison between the use of epicycles in astronomy and the issues of modern physics to highlight the potential misinterpretation of mathematical models for physical reality. In both cases, he argues, a complex mathematical framework is used to describe observed phenomena, but the underlying "meaning" or interpretation of the equations may be a flawed, self-created overlay rather than an accurate description of nature.
The epicycle analogy
Ancient astronomy: The ancient geocentric model, which placed the Earth at the center of the universe, failed to explain the observed retrograde motion of planets (their apparent reversal of direction in the night sky). To "save the model," astronomers added complex mathematical constructs called epicycles—circles moving along larger circular orbits.
The flawed interpretation: While the system of epicycles could accurately predict planetary positions, it was based on an incorrect foundational assumption. It was a mathematical description of observations that obscured the simpler, more accurate physical reality—that the Earth and other planets orbit the sun.
The modern physics comparison
McEachern applies this historical lesson to modern quantum mechanics, arguing that physicists risk making a similar mistake.
Mathematical description vs. physical reality: He contends that modern physics accurately describes many experimental observations with its equations. However, the conceptual "meaning" attributed to these equations—such as inherent non-locality, entanglement, and the uncertainty principle—is a "slapped-on" interpretation that may not reflect the true nature of reality.
The role of information theory: McEachern's interpretation is based on applying Shannon's Information Theory to quantum mechanics. He argues that many quantum paradoxes arise from misinterpreting the nature of information and measurement.
For example, he claims the uncertainty principle isn't a statement about nature's fundamental "fuzziness" but about the mathematical limits of extracting information during a measurement.
The "observer" issue: McEachern emphasizes the distinction between mind over matter and mind over mind. He suggests that the observer's "mind" primarily influences the interpretation of results, not the physical outcome itself. The equations may be correct, but the interpretation given to them is a human construct, much like the epicycles.
In essence, McEachern's comparison is a cautionary tale, suggesting that the "weirdness" of quantum mechanics may be a sign that physicists have, like their astronomical predecessors, fallen into the trap of confusing their mathematical tools for the underlying physical truth. He proposes that a different, more information-centric interpretation may offer a simpler and more intuitive understanding of reality.
