I know, "Any headline that ends in a question mark can be answered by the word NO", and i dont think FTL will ever be possible, but for a few weeks now i have this idea of a possible FTL-ship in my head which i never heared of anywhere. it depends on the properties of dark energy and some othe stuff and probably will not work, but i cant think of any scientific proof against it... so here it is:
How about moving a spaceship by creating chunks of spacetime behind it and (maybe, if possible) deleting chunks of spacetime in front of it? as far as i know dark energy is supposed to do exactly that all the time (creating chunks of spacetime). your "speed" should be limited only by how fast you can create (and maybe delete) spacetime.
If dark energy realy is creating new spacetime this should work (?) or is dark energy only stretching spacetime?
what do you guys think?
