Gravity is not an entropic force

TL;DR

This paper refutes recent claims that gravity is an entropic force by presenting experimental evidence from ultra-cold neutron experiments in Earth's gravitational field.

Contribution

It provides experimental evidence challenging the hypothesis that gravity originates from entropic considerations.

Findings

Ultra-cold neutron experiments contradict entropic gravity models

Experimental data supports traditional gravitational theory

Disproves recent entropic gravity speculations

Abstract

We argue that experiments with ultra-cold neutrons in the gravitational field of Earth disprove recent speculations on the entropic origin of gravitation.
