Penrose (2004: 731):
Gravity seems to have a very special status, different from that of any other field.

To be clear, a physical field is a region of spacetime under the influence of some agency. From the perspective of Systemic Functional Linguistic Theory, a gravitational field is different from other types of field in as much as it is the dimensions of spacetime itself that are affected, since the agency (mass) causes the relative contraction of space intervals, and the relative expansion of time intervals, with increasing proximity to its centre.
