What is the parameter or mechanism that needs to be considered in order to design a spacecraft that could bend and stretch the fabric of space-time?
You probably cannot do it with a spacecraft since huge masses are needed.
Thanks for your answer. Perhaps it should be more like a space capsule instead of spacecraft but could move at a superluminal motion. Something that could be propelled by a huge mass enough that could bend and stretch the fabric of space.
There is a metric that decribes this, found by Miguel Alcubierre. The use of the metric to achieve superluminal motion is called the Alcubierre Drive. See the attached link and references therein for details. The key problem is that it requires a large amount of negative mass, which is a substance that probably doesn't exist.

Thanks for the link. I think i've heard the idea about the warp drive somewhere before, its quite interesting. what do you think about the casimir effect that could create an energy inside vacuum space?perhaps those energy could be use to substitute the huge mass or exotic matter required?
The problem is that it only has an appreciable effect over a very short distance and the mass of the reflectors would be far greater than the effect.
