Now, few questions...
1) If nothing with mass can accelerate past c, does it mean that any particles faster than c would have negative mass?
2) One of problems with warp drive is that it requires creation of a black hole or equivalent in front of the ship. This would solve problems with objects (and radiation) hitting the ship at high speed... but wouldn't radiation generated by a feeding black hole still be dangerous?
