Consider the Alcubierre drive (sorry for not posting a link for this). In theory, this drive creates a "warp bubble" that travels arbitrarily faster than light and requires negative energy on the outside of the bubble to function, presenting two problems:
1.) How do you produce enough negative energy?
2.) How to you keep the negative energy conditions needed outside of the warp bubble following the warp bubble?
We could call the first problem a simple matter of engineering, since we can produce negative pressure with the Casimir effect already, but the second problem would need drastic solutions like laying down and maintaining the conditions required to maintain the warp field, like a space highway.
From my armchair, I maintain that these problems are actually insurmountable, as taken together they require that we basically build a tunnel from here to any star we want to go. So why don't we think on a smaller scale?
Like super-reletivistic telephone cables?
If we could send a warp bubble down a cable, we could increase transmission speed to the point where it could very well break causality. There would still be engineering hurdles to overcome, but not any of the "crochet ladder between the Earth and Andromeda" kind.Statistics: Posted by daydreamer — Fri Dec 11, 2015 4:41 pm
