Dr. Maxlow's Research
Dr. Maxlow's interests in Expansion Tectonics stem from a dissatifaction with plate tectonics in explaining geological phenomena. As part of his PhD research into global tectonics, he created models of an expanding Earth from the present back to the early Archaean Era. This is the first time that both oceanic and continental crusts have been used to reconstruct plate assemblage for the entire 100% of Earth history. Models were then used to layer global geographical, climatic, geophysical and geological data to quantify an Earth expansion process (note: Earth expansion = growing Earth).
Yes! The Earth is Expanding.

What's causing the Earth to expand ?
1.A pulsating Earth, where cyclic expansion of the Earth is said to have opened the oceans and contractions have caused orogenesis (mountain building). This proposal fails to satisfy exponential expansion, as shown by modern oceanic mapping, and Professor Carey considered the theme to have arisen from the false misconception that mountain building implies crustal contraction. In addition, Carey saw no compelling evidence for intermittent contractions of the Earth.
2.Meteoric and asteroid accretion. This is currently a popular theory, proposed also to explain some of the various extinction events that have plagued the Earth. It basically says expansion is caused by an accumulation of extraterrestrial debris over time. This theme was rejected by Carey as the primary cause of Earth expansion, since expansion should then decrease exponentially with time, not increase as shown by the oceanic mapping. Nor does it explain ocean floor spreading, or the distribution of oceanic crust or covering sediments.
3.Constant Earth mass, with phase changes of an originally super-dense core. This was again rejected by Carey as the main cause of Earth expansion because the theme implied too large a surface gravity throughout the Precambrian to Late Paleozoic Eras. A large Precambrian surface gravity was not evident from studies carried out during the 1970s. For a constant Earth mass, density would have also been unacceptably high during the Precambrian.
4.Secular reduction of the universal gravitation constant G. Such a decline of G was said to cause expansion through the release of elastic compressional energy throughout the Earth, and phase changes to lower densities in the mantle. Carey rejected this proposal as the main cause of expansion for three reasons: (a) formerly the surface gravity would have been unacceptably high, (b) the magnitude of expansion is probably too small, and (c) the arguments for such a reduction in G were considered not to indicate an exponential rate of increase in radius.
A cosmological cause involving a secular increase in the mass of the Earth. This suggestion remains the most popular theme.
Expansion Tectonics as a viable scientific fact
Put simply, the process of Expansion Tectonics, from the beginning of geological time to the present can now be accurately constrained. This has never been achieved before and in itself quantifies Expansion Tectonics. By using modern global geological and geophysical data our Earth is shown to have undergone a steady expansion throughout the Precambrian Eras, prior to a rapidly accelerating expansion during the more recent eras, and continental break-up and opening of the modern oceans during the past 200 million years to the present.
With this modern geological and geophysical data we now have the means to accurately quantify an Earth expansion process, making the evidence in favour of expansion very favourable. In order to accept Expansion Tectonics as a viable global tectonic concept, we must, however, be prepared to remove the constant Earth radius premise in order to encourage active research into alternatives too currently accepted global theories.
Modern measurements have established very stringent upper bound limits for the expansion rate, which very much reduces the possibility of an expanding Earth. For example, paleomagnetic data has been used to calculate that the radius of the Earth 400 million years ago was 102 ± 2.8% of today's radius. Furthermore, examinations of earth's moment of inertia suggest that no significant change of earth's radius in the last 620 million years could have taken place and therefore earth expansion is untenable.

The plasma / solar material.
I'm sure I've seen this pass in the videos in the OP.
It's not fully explained but just enough to get the idea.
