		+	The '''gravitational interaction''' is the mechanism by which all [[particle]]s with [[mass]] affect one another.
		+
		+	===About The Gravitational Interaction at Subatomic Scales===
		+	: The '''gravitational interaction''' is one of the 4 [[Fundamental Interactions\|fundamental interactions]] governing how [[particle]]s affect one another.
		+	: The '''gravitational interaction''' causes all [[particle]]s with [[mass]] to be [[attract]]ed to one another.
		+	: The '''gravitational interaction''' is extremely weak on the scale of [[Relative Atomic Mass\|atomic masses]] but is 'long range' and cannot be shielded, so accumulates with large numbers of [[atom]]s to be observable at macroscopic scales.
		+	: The '''gravitational interaction''' may be mediated by an, as yet, undiscovered [[Fundamental Particle\|fundamental particle]] called a [[graviton]].
		+
		+	===About The Gravitational Interaction at Macroscopic Scales===
		+	: Due to its long range and the inability to shield the '''gravitational interaction''' it is responsible for the large scale structure of the [[Observable Universe\|observable universe]].
