    Graduate Reflecting Gamma Rays w/ Electron Gas for Spacecraft

    Technically, for propulsion purposes you wouldn't need to be able to reflect the photons given off. Even if you just absorbed them you would gain a propulsive force from the radiation pressure, but the force would only be half of the maximum available from pure reflection. I don't know if that...

This is not the case and instead what we see is that the restoring force has no dependence on the displacement. We can demonstrate this...
