# Planck Time

Max Planck is one of the fathers of Quantum Physics. His work has revealed one of the great secrets of the universe/multiverse. And it *so* is at odds with what is obvious to every living person, so unquestioned as to be axiomatic, fundamental to *all* previous science, all knowledge.

This Reality actually is not smoothly continuous as it appears to us. Rather it progresses in a step-wise fashion similar to a computer’s “system clock.” Just as a movie spins past us at 24 frames per second while “persistence of vision” tells us it is continuous, so the Planck Clock regulates our actions in Einstein’s “persistence of reality.”

This section will be the most math I will present, and you may skim it for the most part without missing anything needed to understand, but it is helpful to get a true feel for the scale of the system into which we are so inextricably woven .

Plank’s work is described at On Truth and Reality: Max Planck and here at Planck’s Constant and The Origin of Quantum Mechanics and is fundamental to the understanding of the nature of physicality. The good news – just ignore the math, but to grok the philosophical and practical considerations of these discoveries, learning what these quantities signify is really enough to start. There are a number of useful sites to explain this phenomenon:

Basically, Planck has defined for us the inner limits of resolution of the Universe/Multiverse. And we can use *this *information to back ourselves up the Stairway to Reality to discover what we really are made of (and it’s neither “snips, snails and puppy-dog tails” nor “sugar and spice and everything nice.”

### Planck Units

Planck’s constant (*h*) defines the relationship of energy (of a photon) to frequency. The relationship is defined by: E = *hc/λ (*wavelength), *i.e.*, the energy of a photon is equal to its frequency times Planck’s constant. *h*=Planck’s constant

The system of Planck units was designed to make the lives of quantum physicists easier still. In the Planck unit system, five basic constants of the universe — the speed of light (c), the reduced Planck constant (*ħ*), Newton’s gravitational constant (G), the Coulomb constant (ke), and the Boltzmann constant (kB) — are all set equal to 1. The base units of length, time, mass, electric charge, etc., are then derived from these constants.

## Planck Time is the earliest time for which a valid description of the universe can ever be made.

Some of the Planck units, such as the Planck mass and the Planck charge, seem not to have any fundamental meaning themselves and could very well end up being completely arbitrary; but others have special significance within the quantum world.

The Planck Length is, theoretically, the shortest distance that can possibly be measured. It is approx 1.6 x 10^{-35} m, about 1020 times smaller than the nucleus of an atom.

The Planck Time is the time taken to travel the Planck length at the speed of light. It is approx 10^{-43} seconds. It is also the earliest time for which a valid description of the universe can ever be made.

The Planck Density is one Planck mass per cubic Planck length. It is much denser than all but the tiniest black holes. One unit of Planck time after the Big Bang, the mass density of the universe is thought to have been one Planck density.

The Planck temperature unit is about .4 x 1032 Kelvin. It’s about 9 x 1024 times hotter than the core of the sun, and is theoretically the highest temperature at which matter could exist at all. One unit of Planck time after the Big Bang, the temperature of the universe is thought to have been one Planck temperature.
