…a material that is nigh weighless when moving away from gravity but gains mass again when moving towards it.

My brain hung a bit in this statement. I suppose I incorrectly interpreted “nigh weightless” as “losing weight”, which is what everything does as it leaves a gravity well.

It’s 4am here and I’m just browsing on my way to the airport, half asleep. So, please feel free to ignore this whole thing.
