fundamental space : a description of space as the fundamental geometrodynamical quantised field

The vision of Clifford and Einstein can be summarized in a single phrase:

A Geometrodynamical Universe
A world whose properties are described by geometry, and a geometry
whose curvature changes with time - a dynamical geometry.

~ John A Wheeler
Curved Empty Space-Time as the Building Material of the Physical World

⁌    

There is nothing in the world except curved empty space. Matter, charge,
electromagnetism and other fields are only manifestations of the bending
of space.

Physics is geometry.

~ John A Wheeler
on W K Clifford's monistic ontology

•  

If we imagine the gravitational field to be removed, there does not
remain a space, but absolutely nothing.

There is no such thing as an empty space, i.e. a space without field.

Space-time does not claim existence on its own, but only as a
structural quality of the field.

~ Albert Einstein
