Já podemos sonhar com naves interestelares sem cair no ridículo:
NASA has unveiled conceptual designs for their theoretical warp drive propelled starship. The IXS Enterprise concept was developed at the NASA Eagleworks Advanced Propulsion Physics Laboratory, based on the theoretical work of Dr. Harold White. The conceptual starship designs were rendered by artist Mark Rademaker with help from designer and technical consultant Michael Okuda.
The IXS Enterprise is certainly not something we are likely to see built and flown to the stars anytime soon. It is, however, based on Dr. White’s equations for what a warp capable ship might look like if NASA were to build one today.
That is, if they could produce the proper amount of energy to warp spacetime using such a magnificent looking interstellar vehicle. The good news is that more recent research has determined that the initial energy requirements for such an effort are not as demanding as previously calculated.
