quantum foam

Some time ago I posted the results of experiments suggesting it may be possible to transfer momentum into vacuum, thus, enabling propellant-less propulsion. Somewhat controversial idea, potentially, supported by the Dynamical Casimir Effect. Both beam balance and torsion balance results were...

I am a medical doctor with only an amateur interest in space-time, so please forgive me if this is stupid. Has anyone thought about gravity in the following way? We know that space-time distorts near massive bodies so that "time flows more slowly" there – gravitational time dilation, right? We...
