** In a groundbreaking revelation, physicists have suggested that all of nature can be explained using just one fundamental constant, challenging the current reliance on multiple base units like seconds, meters, and kilograms. Traditionally, these units are derived from fundamental constants such as the speed of light and Planck’s constant. However, the new paper proposes using a single time standard to measure everything in the universe. This is achieved through ingenious methods like the “three clock experiment” and the use of a Kibble balance, both allowing for the measurement of distances and masses solely using time. While the concept raises questions about its applicability at quantum levels, it marks a significant advancement in understanding the universe. **
