>he uses gravity waves to 'clear a path'
I remember in physics classes 60 years ago about brainstorming how to move a spacecraft to faster than light velocities by distorting space/time in the area directly ahead of the line of travel. I think Gene Roddenberry got wind of our research and wedded it with the (then theoretical) existence of antimatter to create his "warp" drive in the series Star Trek.
It would involve "warping" space/time using the interaction between matter and antimatter's unimaginable energy to create something like artificial gravity waves to achieve just this.
My father was also a physicist, and his circle of friends (mostly AAF vets) disappeared into black project think tanks after the war and their getting their advanced degrees. Truth may be stranger than fiction. Who knows what they have cooked up in the last 75 years?
