Well, Space-time doesn't hold anything together, because the Anima Mundi does. Imagine the Force from Starwars, except it wasn't ruined by any Prequels. It's all around you, everywhere, a magical force that holds together everything. When someone tampers with the Anima Mundi, bad things happen (See: Toxic Oil in the Elven Lands).
 * Space-time is unstable. In fact, if there was nothing to hold it together, it would rip itself apart and the plane of Gielinor would cease to exist.
 * A sea of energy called the Quantum Matrix is what holds the space-time in the entire plane of Gielinor, and most other planes, together. This energy is composed of subatomic particles called psions, which have EXTREMELY low mass. The energy field that they emit stabilizes space-time.

My problem with this theory is: It's actually overly-complicated and takes away the mysticism of the game. It just degrades the wonder of magic, and it's unneeded.
