Yes, gravity does exist in a vacuum. A vacuum does not need to be completely devoid of matter, it just needs to have a lower pressure than the area around it. Consider the syringe above.

WebForce is related to mass and the distance between objects, but G remains the constant in Newton’s force equation. The electric force is modeled with the wave amplitude reduction equal to gravitational coupling constants for the electron and proton. For two particles like two electrons, the slight reduction is negligible in force measurements.
