    "concept_summary": "Spears proposes that gravity can be described as an electrostatic phenomenon arising from the permittivity of free space. By arranging pairs of high-voltage electrodes in a grid (an \"artificial gravity mat\"), a capacitance-based force is produced that mimics the effect of gravitational attraction. The theory derives the gravitational constant G from electrostatic parameters and claims that the resulting force can be used for spacecraft artificial gravity or to pull floating objects toward the electrode array.",
