Nonquantum Gravity

TL;DR

This paper explores the possibility that gravity is inherently classical and nonquantum, analyzing the experimental implications and suggesting that evidence for nonquantum gravity might be observable at mesoscopic scales.

Contribution

It proposes a heretical perspective that gravity may not be quantized and investigates the potential experimental signatures of nonquantum gravity.

Findings

No current experimental evidence for quantum gravity

Potential evidence for nonquantum gravity at mesoscopic scales

Challenges in testing quantum nature of gravity in near future

Abstract

One of the great challenges for 21st century physics is to quantize gravity and generate a theory that will unify gravity with the other three fundamental forces of nature. This paper takes the (heretical) point of view that gravity may be an inherently classical, i.e., nonquantum, phenomenon and investigates the experimental consequences of such a model. At present there is no experimental evidence of the quantum nature of gravity and the liklihood of definitive tests in the future is not at all certain. If gravity is, indeed, a nonquantum phenomenon, then it is suggested that evidence will most likely appear at mesoscopic scales.
