Regarding an earlier statement that science today does not have the means to describe let alone create craft that travel at incredible speeds while remaining outside the bounds of crushing G force inertia...

Not true.

We can describe, test and prove that mass can be put into higher wave functions that reduces their inertial effects as well as reducing the effects of gravity by at least two different means.
What we do not have is a self contained power plant to produce the "gazillion volts/amps" to do it, and even if we did, the damn thing could be far more dangerous than nuclear power.

"Opps Detroit has been pulled into a singularity mishap today , thousands flee to Traverse City..." being rid of Detroit might be OK but dealing with a huge power source for the first time is clearly a hazard.

Observations are helpful despite all the problems they present so,

Remarkable personal observations aside...the uncommon phenomenon continues to be observed.



As to how it does what it does I am reduced to intuition.

My imagination predicts that:)
The centrifugal forces of high speed paricles around the perimeter of a flying disk or diameter of a flying cylinder is one kind of anti grav device while the high speed drive is entirely different.
It's a long shot wager but thats how I picture it.
