What is the source of inertia?

[fasteddie1371]

Is there a specific particle or force that gives an object inertia? Going back to the 1940's science fiction ideas of "inertialessness", is there a way to nullify or remove an objects inertia? And if so, could an inertialess object go faster than light?

No; inertia is the name for the phenomena that objects with mass resist acceleration.

According to the theory of relativity everything related with energy, momentum, and stress contributes to inertia as well as gravity.
