Why Eppley and Hannah's Experiment Isn't

TL;DR

This paper critiques Eppley and Hannah's thought experiment, arguing it is fundamentally flawed, unfeasible to build, and would collapse into a black hole, thus invalidating their conclusion that gravity must be quantized.

Contribution

It provides a detailed analysis showing the flaws and physical impossibility of Eppley and Hannah's proposed experiment to prove gravity's quantization.

Findings

The proposed device cannot be constructed with known physics.

The device would be so massive it would form a black hole.

The experiment's assumptions are physically implausible.

Abstract

It is shown that Eppley and Hannah's thought experiment establishing that gravity must be quantized is fatally flawed. The device they propose, even if built, cannot establish their claims, nor is it plausible that it can be built with any materials compatible with the values of c, h, and G. Finally the device, and any reasonable modification of it, would be so massive as to be within its own Schwarzschild radius--a fatal flaw for any thought experiment.
