Expanding Earth Hypothesis and Pre-Cambrian Earth

Abstract

There is empirical support for the view that the oxygenation of oceans did not occur before CE. This conforms with the prediction that oxygenation was due to photosynthesis in underground oceans. TGD provides the new physics needed: dark photons from either Earth's core or Sun could have provided the metabolic energy making photosynthesis and therefore oxygenation possible.
