// This part effectively cancels the ship's inertial mass and modifies the engine exhaust stream's inertial mass by manipulating the Zero-Point Field (ZPF).
// This effectively increases an engine's thrust and Isp, resulting in a greater TWR and delta-v.
// What's cool is that this technology meshes with Blueshift's existing warp tech too. The ZPF, from which this concepts arises, is already tied to negative energy effects (like the Casimir effect)- the same physics often cited as a possible Alcubierre drive.
// Hence, the Zero-Point Inertial Dampener is a stepping-stone to warp tech.
// Though totally fictional and definitely inspired by Mass Effect, here are some real-world references
// that I researched while coming up with this plausibly deniable part module.

// Important notes
// These ideas are theoretical and unconfirmed by experiment.
// They lie at the fringe of mainstream physics, but remain internally consistent within classical and quantum electrodynamics.
// NASA’s Breakthrough Propulsion Physics Program explored related concepts but found no conclusive path to engineering.

// Background: Zero-Point Energy & Casimir Effect
// Source: https://en.wikipedia.org/wiki/Zero-point_energy
// Summary:
//    ZPE is the lowest energy possible in a quantum system.
//    The Casimir effect experimentally confirms the existence of vacuum fluctuations.
//    While ZPE is proven, harnessing it for inertia or propulsion remains unverified.

// Published: Physical Review A, 1994
// Link: https://www.researchgate.net/publication/13379419_Inertia_as_a_zero-point-field_Lorentz_force
// Summary:
//    Proposes that ZPF electromagnetic fluctuations exert a Lorentz-like force on accelerating matter.
//    Suggests that this interaction accounts for inertial mass.
//    Establishes a theoretical foundation tying ZPF to classical electrodynamics and relativity.

// Authors: Rueda, Haisch
// Published: arXiv Physics, 1998
// Link: https://arxiv.org/abs/physics/9807023
// Summary:
//    Expands on earlier work by modeling interactions at subatomic levels.
//    Argues that particle mass may arise from cumulative electromagnetic drag from the vacuum.
//    Connects the idea to quarks and electrons, proposing a universal mechanism.

// Let's face it, this is Space Magic, but at least it's internally consistent with Blueshift's other tech.
