Universality, Gravity, the enigmatic Lambda and Beyond

TL;DR

This paper presents a novel perspective on the role of universality in physics, connecting classical, relativistic, and quantum realms through the concept of zero mass particles and universal fields, and explores implications beyond general relativity.

Contribution

It introduces a new conceptual framework linking universalization with fundamental physics, emphasizing the role of zero mass particles and universal fields in unifying classical and modern theories.

Findings

Zero mass particles lead to special relativity.

Interaction with universal fields results in general relativity.

Classical argument suggests universal force must be attractive.

Abstract

In this essay, I wish to share a novel perspective which envisions universalization as a guide from the classical world to relativistic and quantum world. It is the incorporation of zero mass particle in mechanics which leads to special relativity while its interaction with a universal field shared by all particles leads to general relativity. We also give a very simple classical argument to show that why the universal force has to be attractive. We try to envisage what sort of directions does this principle of universality point to for the world beyond general relativity?
