This answer is poorly researched and fairly vague, but I'm pretty sure none of it's _incorrect_ (apart from the speculation about moving wormholes through each other, which almost certainly is). (more) |

A: What would one experience travelling through an invisible Krasnikov tube, and how much could they be used to cut travel times? > What would one experience travelling through an invisible Krasnikov tube? A flat piece of paper doesn't quite lie flat, and the walls on your ship are under considerable stress (unless the ship's built to handle being in non-Euclidean geometries). Apart from that, not much; it's just spacetime, ... (more) |

(Their voices would still be higher than a full-sized, anatomically-correct human's, though.) To get an even lower range, they could have a st... (more) |

A: Limitations to replicator technology: energy and fuel Your replicator is a programmable universal catalyst combined with a 3D printer. It can force any particular chemical reaction to occur over others and deposit the result of that chemical reaction in an arbitrary arrangement. However, it cannot violate conservation of energy. So, how much energy is ... (more) |

Limitations to replicator technology: energy and fuel Replicators have become a staple of science fiction. However, many stories treat them as magical, or with inconsistent abilities. This is not a magical device that makes anything for nothing. When fed a source of certain atoms (it can't transmute atoms), it will rearrange them into whatever it is p... (more) |
