- galcerte 4y agoWe do not know if and I bet plenty of people do not believe such negative energy really exists. Besides, all warp bubble metrics so far are inertial; meaning the ship is unable to accelerate, so they're a gimmick nowadays. I have hopes we find something workable though.

Plenty of people believe that mental problems are all caused by disembodied souls unleashed by Xenu of the Galactic Confederation when he blew them up with A-bombs in Hawaii, back when Earth was called Teegeeack. What "plenty of people" believe is not important.
- midoridensha 4y agoAlso, "plenty of people" used to believe the Earth was flat, or that the Sun orbited it.
- forgotpwd16 4y agoNot only negative energy but insane amounts of it as well. Originally required converting more mass than the entire observable universe. That was lowered in later works. A recent work moreover made a drive using only positive energy.
- simiones 4y agoNote that the newer, positive energy drive had the warp bubble itself moving slower than the speed of light. Still very interesting in principle.
