# Pregeometry

Tue, Feb 28, 2012In physics, a *pregeometry* is a structure from which geometry develops. The term was championed by *John Archibald Wheeler* in the 1960s and 1970s as a possible route to a theory of *quantum gravity*. Since quantum mechanics allowed a metric to fluctuate, it was argued that the merging of gravity with quantum mechanics required a set of more *fundamental rules* regarding connectivity that were independent of topology and dimensionality, and which could work independently of any assumptions we might make about the properties of a surface.

Where “*geometry*” could describe the properties of a known surface, and the physics of a hypothetical region with pre-defined properties, “*pregeometry*” might allow us to work with deeper underlying rules of physics that were not so strongly dependent on *simplified classical assumptions* about the properties of space.
