Do you think that the warp drive will ever be pos­si­ble?

All About Space - - Michio Kaku -

Ein­stein said it is very dif­fi­cult to break the light bar­rier [the speed of light]. To have a rocket go up to the speed of light you have to have fu­sion rock­ets, anti-mat­ter rock­ets and maybe ram­jet fu­sion rock­ets.

But to ex­ceed the speed of light you have to in­voke gen­eral rel­a­tiv­ity, and you have to have enor­mous amounts of en­ergy. En­ergy that is com­pa­ra­ble to an ex­plod­ing star or a black hole. There is a pos­si­bil­ity that if you can har­ness this vast amount of pos­i­tive en­ergy, you can open a gate­way through space and time. How­ever, you would need neg­a­tive en­ergy to sta­bilise it.

So if you have this rare com­bi­na­tion of pos­i­tive en­ergy to open up the gate­way, and neg­a­tive en­ergy to sta­bilise the gate­way, then warp drive may – just may – be­come pos­si­ble.
