To the extent I see energy generating the patterns, thus energy going past to future, as the patterns coracles and dissolve, the energy drives the waves the fluctuations rise and fall, I suspect the reason there is far more gravitational effect, than mass/matter to explain it, is because the properties we, as tactile, object oriented creatures, treat as mass, are intermediate effects of this relationship between energy and form.

Basically mass isa effect of gravity, rather than gravity a property of mass. That gravity is the more evident part of the resonance and centripetal effect across the entire spectrum of waves.

The music is more real than the matter.

One thought I had about giantism in dinosaurs is whether there simply has been enough astroid and meteor impacts to measurably increase the size of the earth, that its gravitational attraction has increased since then. Simply things were not as heavy. Though in the overall age and evolution of the planet, this effect would likely be quite limited in the last 63 million years.

There was certainly a lot of megafauna before the last ice age. It might simply be that people have prevented other species from evolving back to larger sizes since then, as they make bigger targets.

As for the size of the universe, I guess that depends on the relationships with the rulers. I tend to assume some stability, unless effective evidence otherwise.
