If you like to go to the remote stars by warping the fabric of spacetime, you need to find a proper metric. Also, you need to produce sufficient amounts of the exotic matter, required for that geometry. It is argued that the applicable metric can be read as so:

Now, let us explain some features of the above metric:

1) The metric is subjected to two time factors. One needs them to manage the size and the energy requirements of the wormhole.

2) The metric represents a traversable wormhole; however it is designed in a proper arrangement to accept a warp bubble at the further geometrical surgeries.

3) It contains the charge element, as a back-reaction operator. The present technology has the most capability of manipulating the metric, via this part.
