Gravity and inertia, two of the most fundamental attributes of any object possessing mass.

Research into the understanding of the fundamental natures of both is currently being conducted by the Office of Scientific Research with the assistance of the deep space station Centarus. It is considered (ever since Newton’s articulation of his three laws of motion) an axiom by science of the existence of inertia.

In experiments conducted in the area of quantum theory, inertia is [in effect] the consequence of the bizarre subatomic happenings that take place in ostensibly empty space [see osr9405.01d for more on this]. For on such minute a scale, random quantum fluctuations roil the vacuum, creating a cauldron of virtual particles, which continuously pop in and out of existence.

And these fluctuations (termed the zero point field) effect normal matter as well, and gravity itself is a long-range effect of them.

This field contains tremendous energy and [as stated by Einsteins equation] energy is equivalent to matter, thus... it would be expected to create an intense gravitational tug [such does not correspond with the observed structure of the cosmos however]. But as the field gives rise to gravity, the energy within would not necessarily produce such themselves.

However, this research is in its most fundamental stages, and will require more study to confirm any findings.
