Inertia isn’t a property of matter as such, but a property of the quantum vacuum in which matter is embedded. Matter itself has no intrinsic inertia.] The vacuum imposes inertia? [It isn’t really a vacuum, not at the quantum level. It’s a seething foam of rich interactions: a broiling sea of fluctuations, with particles and messenger-particles in constant existential flux, like glints of sunlight on ocean waves. It’s the choppiness of that sea which creates inertial mass, not matter itself. The trick is to find a way to modify the properties of the quantum vacuum—to reduce or increase the
