one with no engine but moves by bending space. Instant travel by never having to travel any distance, be it a few feet or a billion light years.
this removes the faster than light issues with time dilation, acceleration G-force effects and the fact that energy requirements to go the speed of
light are probably more than the energy required to bend space.
spherical in shape, centrally located 'bridge'.
