Notes on the Origin of Gravity and the Laws of Newton

TL;DR

This paper explores the physical origins of gravity and the laws of Newton, providing derivations based on quantum mechanics, special relativity, and gauge theory, and supports the idea that gravity is emergent rather than fundamental.

Contribution

It offers simple derivations of the origin of gravity and the Unruh effect without relying on holographic screens, advancing the understanding of gravity's emergent nature.

Findings

Provides a physical origin of the Planck length.

Derives gravity laws without holographic screens.

Supports gravity as an emergent phenomenon.

Abstract

Following Verlinde's recent work on the origin of gravity and the laws of Newton, we consider further the origin of the starting point of Verlinde's work and Unruh effect. Simple derivations are given for this starting point and Unruh effect with the standard theory about quantum mechanics, special relativity and 'vacuum' background based on the gauge field theory. Our studies give the physical origin of the Planck length. The present work supports further the idea that gravity is not a fundamental force. In the present work, the concept of holographic screen is not absolutely necessary to derive the universal gravity and the laws of Newton.
