Potential of String Theory
Might a future contribution from string theory help explain why a space vehicle travelling beyond the speed of light and accelerating constantly at for example 10G would place the occupants under only the strain of 1G? That ratio to be explained in a string theory differential between natural "pull" gravity and artificial "push" gravity. That is to say on earth 2G acceleration against gravity would place a strain of 2(1) +1=3G. However in the absence of any significant "pull" gravity (e.g. between two suns being the extremes) then relationship is factored away from (1). For example 10G becomes only 1G. e.g. 10(0.1) =1.
Potential of String Theory continued
The first consideration is whether the velocity of the object (measured under light speed, and then beyond light speed by a variety of factors) would be part of or independent of the proposed string theory differential that reduces through fractional constants natural and artificial gravity aggregated on the human when natural gravity is much less than 1. That is to say in weightlessness, might string theory advocate why an astronaut might be propelled forward at 10G but experience only 1G.
