Whoever said the speed of light is unattainable?  Oh yea, Einstein .  Well, who cares what he said, here's how to do it.
    The Warp Propulsion System (WPS) is the single most complex system aboard a starship.  In essence this crucial system bends space and allows for faster-than-light travel.  Who came up with this idea you ask? Zefram Cochrane did.  He is generally accepted as the father of modern warp physics.  Warp drive, or continuum distortion propulsion (CDP), was first developed by Cochrane and his amazing engineering team during the middle of the 21st century.  It was this type of propulsion that allowed for practical deep space operations beyond our solar system. In Cochrane’s original theories, single or double subspace fields produced with awesome power output, can warp the space-time continuum enough do drive a starship at superluminal speeds. These fields allow a vehicle to switch between two different speeds while spending less then Planck Time , one of the many things Planck created, in either state. This has the net effect of propelling the vessel at and past the previously thought to be unattainable speed of light while avoiding the infinite energy requirement that was predicted to be necessary at that speed.
    You are probably wondering if there is a unit of measurement for all the stuff, or maybe you aren't.  But, I'm going to tell you anyway.  As you probably already guessed, thanks to his contributions to the development of warp field theory, the unit used to measure subspace field stress is the Cochrane. Cochranes are used to measure the field distortion produced by other spatial manipulation devices, including tractor beams, deflectors, and synthetic gravity fields.

    Doesn't that look complicated?  Its not really that bad.  As you can see from the graph warp 3 is about 39 cochranes or 39 times faster than the speed of light.  Just follow the line for warp three up to the black line and move to the left.  That is how many times faster than light you are traveling.  That number also happens to be the amount of cochranes.  The blue line is power output.  Every peak is a threshold.   One must obtain that much energy to reach that warp factor.  After that power usage goes down like in the graph.  Notice the extreme power needed to reach high warp factors.  How is it done?  Find out!
