A Nuclear Data Approach for the Hubble Constant Measurements

TL;DR

This paper applies nuclear data analysis techniques to synthesize numerous Hubble constant measurements, resulting in a recommended value of 66.2 km/sec/Mpc and an estimated universe age of about 14.78 billion years.

Contribution

It introduces a nuclear data approach to consolidate diverse Hubble constant measurements, providing a new recommended value based on 25 years of experimental data.

Findings

Recommended Hubble constant: 66.2(77) km/sec/Mpc

Estimated universe age: approximately 14.78 billion years

Unified value derived from multiple measurement types

Abstract

An extraordinary number of Hubble constant measurements challenges physicists with selection of the best numerical value. The standard U.S. Nuclear Data Program (USNDP) codes and procedures have been applied to resolve this issue. The nuclear data approach has produced the most probable or recommended Hubble constant value of 66.2(77) (km/sec)/Mpc. This recommended value is based on the last 25 years of experimental research and includes contributions from different types of measurements. The present result implies (14.78$\pm$1.72)$\times$10$^{9}$ years as a rough estimate for the age of the Universe. The complete list of recommended results is given and possible implications are discussed.
