Perhaps dark energy powered cosmic expansion is simply an affect of a big crunch? [:o)]

When the crunch condenses below its Schwarzchild Radius, I propose a duality is formed, being the Lorentz Transform imaginary values associated with <Sr distances - we know time=0 at an event horizon; therefore, beneath this boundary, t becomes a dualistic positive/negative ..... basically, the inner convergence co-manifests as a recursive, out-riding expansion. This suggests our universe is cyclic /wavicle like and totally explains why the expansion rate is steadily increasing, as the condensing crunch produces exponetially increasing t/ti values.

Even wilder speculation;- I believe every particle, even the humble photon may obey this simple process (implying - the universe is just another particle )

Convergence for a photon produces a point 0-D singularity via its very own Schwarzchild radius, albeit at extremely small scale distance. i.e; If a photons relativistic mass (hf/c^2 - yes I know photons do not possess mass!) is substituted for M in calculating a Schwarzchild Radius: 2GM/C^2. This photon, say in the visible spectrum (around 600 THz) would produce a figure of about 10^-62 meters, totally smaller than planck length!

The photonic cycle is one of 720° (360° positive/ 360° negative), in which convergence and expansion co-exist simultaneously.

Expansion above the Sr can be thought of as the magnetic component. Similarly, condensation beneath; manifests as the electric component. Thus this duality operates with 180° phase differential, perfectly matching/describing electromagnetism, with each swapping identities @ the Sr 'boundary'.

An electron/ positron pair;- perhaps a ring singularity to hypertorus cycle, imbedded in the expanding wavefront surface of our universe, with photons themselves, as integrated wavicles within a facet of their overall electro-positronic wave-state .... 'riding around' hyperspace.

Musing on ..... your average photon cycles a tad more rapidly than our universe, say 300Ghz compared to maybe once in a trillion years - how can this be so? ..... well, it's all to do with dimensionality. With increasing dimensionality, energy is sprawled about ridiculously thinner;- so what of our universe, an expanding wavefront of possibly hypertoroidal topology?;- our universe of high order dimensionality may have energy spread out rather sparse ..... it's energy concentration that determines frequency, just like low energy photons cycle slower than high ones. Photons, despite having astoundingly less energy than the universe, have absolute lashings to play about within their far lower dimensional wave-space realm. [:o)]
