From what I have read gravitational waves cannot travel faster than the speed of light. And since gravitational waves are part of the fabric of space, wouldn't that disprove the idea behind an Alcubierre Drive?
An Alcubierre Drive tries to create negative mass in front of it and positive mass behind it. Since the negative mass is dependent upon some form of anti/dark matter this idea is already out of reach. However, what if you can, instead, create gravitational waves in front and behind an object (IE have the crest behind the object and trough in front of it) wouldn't that be the same concept as the below Alcubierre Drive? Thinking about it further, the two are different, because the area with negative mass will want to be filled in with some mass, and if you can keep creating negative mass in front of the object it will stay in motion. Now, change the idea to a wave - would you be able to 'ride' that wave?
Does it prove that you can warp the fabric of space to eventually accelerate an object beyond the speed of light? Or, since gravitational waves propagate at the speed of light does that mean we can at least travel at light-speed? If so, how can you prove/disprove that?
Or does the detection of gravitational waves have no bearing on the possibility for humans to travel faster than the speed of light?
Another question would be - is it possible to artificially create gravitational waves to drive said object? What could be a possible method for doing so?
