The title article confirms that scientists have found that particles create a gravity-field. This could be in a very tight microenergetic hz frequency smaller than the period of the average intracellular component. Similarly, time would be an even tighter hz frequency, the vibration of reality, if you will. Known in #T to be along the "10", and to vibrate or resonate with the fabric of existance. Cosmic oil, if you will again.
A spinning superconductor is capable of producing a powerful gravitomagnetic field. This is earth, btw. And the sun. And an atom. If I wanted to build a flying ship that used its own gravity, I'd run a trio of water e- powered superconducting dynamos to spin it at whatever speed I desired to produce gravity sufficient to move the ship in that direction. It'd have to account for other similar ships nearby with its navigational systems. I imagine such intensely dense gravity field forces would taper off shortly.
I also imagine that this would be a good way to encourage particles to travel through time using relativity.
