Well, liberally interpreted physics still aply, and I'm very certain that e=mc^2 is very present in Bionicle, as Toa get their power from elemental energy and 'Toa power' respectively. So the basic laws of the universe still kind of apply, but are subverted by a lot of the things the Great Beings created.

And I always considered Protodermis to simply be Great Being manufactured synthetic matter, but that's a different issue of fan speculation XD.
