Planck time

Planck time Time required for light to travel the Planck length, 10 43 s. 

A pictorial representation of some of the important events in the thermal history of the universe is shown in Figure 12.5. The description of the evolution of the universe begins at 10-43 s after the Big Bang, the so-called Planck time. The universe at that time had a temperature of 1032K kBT 1019GeV) and a volume that was 10-31 of its current volume. [To convert temperature in K to... 

At around 10 to the power -43 of a second, time itself becomes quantised, that is it appears as discontinuous particles of time, for there is no way in which time can manifest in quantities less than 10 to the power -43 (the so called Planck time). For here the borrowed quantum energies distort the fabric of space turning it back upon itself. There time must have a stop. At such short intervals the energies available are enormous enough to create virtual black holes and wormholes in space-time, and at this level we have only a sea of quantum probabilities - the so called Quantum Foam. Contemporary physics suggests that through these virtual wormholes in space-time there are links with all time past and future, and through the virtual black holes even with parallel universes. 

The modem theory of creation begins at Planck time (10-43 seconds) when the universe was very hot and supersymmetric. As the universe cooled supersymmetry was spontaneously-broken into the Poincarfe symmetry (gravity) and the grand symmetry, SU(5) (the grand force). On further cooling SU(5) was spontaneously broken into the electroweak force SU(2) U(1) and the strong force... 

Multiply the Planck mass fMpianck = (he/G)1 2 by c2 to obtain the Planck energy Epianck = (he5/G[12-15]. Divide the Planck energy by the Planck time fpianck = (TiG/c5)1 2 to obtain the Planck power Ppianck = c5/G = 3.64 x 1052W Epianck/c2 = c3/G =... 

Thus our Planck-power hypothesis at least appears to entail a link between the smallest (Planck mass and Planck time) and largest (cosmological) scales, rather than being merely a numerical coincidence.
