The Planck time comes from a field of mathematical physics known as dimensional analysis, which studies units of measurement and physical constants.
The Planck time is the unique combination of the gravitational constant G, the relativity constant c, and the quantum constant h, to produce a constant with units of time.
For processes that occur in a time t less than one Planck time, the dimensionless quantity t < sub > P </ sub > / t is greater than one.
Dimensional analysis suggests that the effects of both quantum mechanics and gravity will be important under these circumstances, requiring a theory of quantum gravity.
All scientific experiments and human experiences happen over billions of billions of billions of Planck times, making any events happening at the Planck scale hard to detect.
