Anomalously high rates of tectonic plate motion and the TGD view of Cambrian explosion

The popular Arstechnica article (see this) tells that the motion between plates was surprisingly fast during Cambrian explosion. The rate of the tectonic motion as relative rate for the distance increase between plates was surprisingly fast: even about 4 times the recent one.

The TGD view of expanding Earth relies on the prediction of cosmic expansion as a sequence of fast periods of expansion for astrophysical objects. The model predicts that the tectonic plates were created in rather fast radial expansion of Earth: radius increased by a factor 2. Cracks giving rise plates were formed because rock is not flexible material.

The model explains the Cambrian explosion: advanced photosynthesising multicellulars emerged from underground oceans as the oxygenated water bursted to the surface. The TGD view of dark matter allows to circumvent the obvious objections against the model and conforms with the recent surprising findings (see this and this).

The fast radial expansion caused a fast increase of the distances between plates. The velocity v of this recession would have been v=dR/dt×ΔΦ, where ΔΦ is the angular distance between the plates and dR/dt is the radial expansion rate .

The duration of Cambrian Explosion was roughly Δ T=30 billion years. Using Earth radius 6,371 km one obtains the estimate dR/dt = R/Δ T ≈ 20 cm/year. v is obtained from this by multiplying with Δ Φ≤2π. The largest rate mentioned in the popular article is v=64 cm/year. The order of magnitude is correct and the rate would have been higher than the average during the fastest periods. From this one This phenomenon could provide a test for the TGD view (see for instance this) .
