Day (Sidereal)
A sidereal day is the time it takes for the Earth to complete one rotation relative to distant stars, approximately 23 hours, 56 minutes, and 4.1 seconds.
History/Origin
The concept of the sidereal day has been used in astronomy for centuries to measure Earth's rotation relative to fixed stars, differing slightly from the solar day used in everyday timekeeping.
Current Use
Sidereal days are primarily used in astronomy and celestial navigation to track the positions of stars and other celestial objects accurately.
Planck Time
Planck time is the theoretical minimum meaningful unit of time, approximately 5.39 × 10^-44 seconds, representing the time it takes for light to travel one Planck length in a vacuum.
History/Origin
Introduced by physicist Max Planck in 1899 as part of his system of natural units, it arises from fundamental constants and marks the scale at which classical ideas about gravity and space-time cease to be valid, requiring a quantum theory of gravity.
Current Use
Primarily used in theoretical physics and cosmology to describe phenomena at the Planck scale, and as a fundamental unit in models of quantum gravity; it is not used in everyday measurements.
