@adder So you are telling us that the Singularity Synusoid comprises of electrical sine-waves but not square waves...
Lets look at lift and propulsion..Lift is a force that does just that..it lifts objects working against gravity....Propulsion propels an object, providing what ever forces are necessary to make the object move from here to there..It is true that lift and propulsion are forces, but they both serve very different purposes.. Lift simply means a force that works in opposition to Gravity, and Propulsion is a force that moves us in a direction, with or without Gravity..
