Inertial force harnessing speculations for fast transport.
Manipulation of inertial forces can provide in technology control of inertial properties of material objects. If this civilization had a control of inertia than fast transport could be achieved even if we don't achieve a control of gravity forces. First of all if we had a control of inertia we could propel objects without internal resistance of inertia what could mean that we can give an object enormous great velocity with very low energy. Inertia is most unexplained force with which we have contact in common life but we don't understand it. The same we could say about gravity but harnessing inertia can have even more impact in out transportation technology than harnessing gravity. Inertia is closely connected with mass of an object in motion and inertial forces can be applied both as inertial propulsion and inertia less propulsion. We know how to obtain the mechanisms of inertial propulsion and thus how to generate inertial forces but nobody know how to control inertial forces
