About these units
Minute (min)
A minute is equal to 60 seconds, a remnant of the ancient Babylonian base-60 (sexagesimal) numeral system. Civilizations such as the Sumerians and Babylonians divided circles, geometry, and time into 60-based increments, an elegant system that persists today in minutes and seconds. Minutes serve as a comfortable human-scale unit—long enough to measure meaningful intervals (such as short tasks or durations in sports) yet short enough to maintain precision in technical contexts. Meteorologists, musicians, aviators, and engineers still rely heavily on minutes because they allow intuitive expression of small-to-medium time spans. Despite its ancient origin, the minute remains an indispensable unit in modern life, reflecting our deep cultural inheritance from early mathematical civilizations.
Planck Time (tₚ)
Planck time is the smallest meaningful unit of time in known physics, defined as the time it takes light to travel one Planck length. It equals approximately 5.39 × 10⁻⁴⁴ seconds. Below the Planck time, current theories of spacetime—General Relativity and Quantum Mechanics—break down, and we enter a regime where quantum gravity dominates. Planck time defines the theoretical boundary of the earliest moments of the universe, immediately after the Big Bang, before classical spacetime emerged. It is not a unit we can measure directly; rather, it represents a fundamental limit set by nature's constants, including the speed of light, the gravitational constant, and Planck's constant. The Planck time is the frontier where physics transitions from the known into the speculative—where time itself may become granular, discontinuous, or fundamentally different from the human conception.
