Aether

[Light Storm]

Ivan Opsipovich Yarkovsky pitched an idea that pretty much dates back to the dawn of science it's self. That being the void of space isn't so empty, but is filled with an energy which I could only loosely call a fifth remaining Platonic solid, the dodecahedron) called quintessence, of which the cosmos and all celestial bodies are made. Anyways, the idea of this one is that after the suns form, and it starts blasting out ions, those particles starting slamming together celestial bodies that being to and continue to grow.

The classical Aether has been abandoned in the early XXth century. It has been partly replaced by more modern concepts like the quantum foam, the vacuum energy. But the relationship between these concepts and the expansion of planet relies on nothing.
