Maybe these pie-in-the-sky ideas are how those unknown white “tic-tac” craft, off the San Diego coast, and chased by carrier-based FA-18s, work.
Gravity and inertia are closely related. Those 'craft' don't operate on petro chemicals and the vacuum energy is permeating everything already. IF those 'craft' are not from our solar system, then the operators have a means to communicate at greater than light speed. And, BTW, light speed is only a speed limit to things with mass or that have 'universe recognized' mass. IF you mask the mass, you travel 'outside the three of spatial and one of temporal. But you are still 'in the Universe', just not the Universe we now sense with our temporally 'locked' selves and instruments.
Without time, events do not occur in the Universe God created.
Without space, a thing does not exist in the Universe God created.
