Okay, I will take my statement back, it is indeed possible to bend light, but
fitting a collapsed star into the Neo1973 will be kinda hard :D.
But, well, theoretically, if there existed a material where the refraction
index could somehow be controlled, that would be a possibility. I guess this
is something we will have to wait for nano technology to bring us.
