Yeah. Expanding space behind you may effectively allow you to recede from the origin point at arbitrary speeds but that doesn't imply you'll get any closer to y

Yeah. Expanding space behind you may effectively allow you to recede from the origin point at arbitrary speeds but that doesn't imply you'll get any closer to your destination. Unless you're also able to compress the space ahead of you (which is what an alcubierre drive would do). You wouldn't be moving through space at all. Your destination would be closer. Arbitrarily closer. Eventually you'll then just reach the destination as if you moved. Now, I'm quite skeptical about the whole idea but I have to admit I didn't do the math. Wm
