Differential quadratic gravimetric timesheer equation for faster than light speeds:
E = ((m*d*r^2)*c^2),
Forthwit the amount of fuel, distance, relative constrants... though a stellar medium, and some would calculate the drag of the matter of the intersteller and gravity well soup. Life, Technology, Pleasure, Preservation. LVPP. Predictive AI with digital cameras, will create a Variable Time-scope to see into the future. If I stand in the room, the most likely outcome is I leave the room or stay in the room. 50/50 chance plus modifiers, if the machine knows me enough. A Pre-Plotted course requires a very good navigational map and is necessary to cross the distances at super-luminary speeds when the blue/red shifted light image of on coming objects is not to be relied upon. Flying blind and dead-reckoned is not recommended, because you will be sure as dead.
