Or is there a more fundamental attribute of the universe that leads to our measurement and perception of the effects of gravity? Here is a link to a page that discusses this.

What are your ideas?
Gravity is probably fundamental at moderate and low temperatures, but possibly not fundamental at the big bang temperature.
Gravity is fundamental, in spite of the challanges in understanding its nature, without it, we cannot understand anything.
Depending how you define "fundamental", gravity is fundamental for astrophysics and cosmology.
It is very likely that gravity is fundamental. A signature of a fundamental theory is existence of a fundamental coupling constant. The Newton's constant G is most certainly fundamental, as it cannot be derived from h and c (or , for that matter, from the electron's charge e).
An alternative view; Entire space, outside basic 3D matter-particles, is filled with an all-encompassing universal medium, structured by quanta of matter. Due to its structure, universal medium is inherently under compression. A 3D matter-particle, in the universal medium, experiences compression from universal medium. This property of universal medium is gravitation. Magnitude of gravitation corresponds to extent of universal medium that exerts the pressure. Extent of universal medium between two 3D matter-particles is always less than extents of universal medium on their outer sides. Hence higher gravitational actions on outer sides tend to move the 3D matter-particles towards each other. This tendency is understood as gravitational attraction or gravity. Gravitational attraction (gravity) is the resultant (relatively a minor by-product) of separate gravitational actions on two 3D matter-particles by universal medium.
Therefore, gravitation is more fundamental than gravity. Universal medium is still more fundamental than gravitation. Matter that provides substance to all real entities is the most fundamental of all. www,matterdoc.info
I believe and support that gravity is fundamental like other 3 forces.
