Sorry I should have been more explicit. I realized what you were trying to say, but I didn't consider it to be valid.
Just because some people were proved wrong about something in the past in no way makes a valid analogy that einstein was wrong about the universal speed limit. I consider your analogy to be irrelevant.
Really? This direct analogy escapes you?
Things like this are only impossible until someone figures out how to do it.
In an Alcubeirre warp-drive, your ship is subjectively sub-light. Warping the space-time around the ship causes the apparent movement. Space-time being essentially mass-less, the Einsteinian “speed of light in a vacuum” doesn’t come into play.
