Hmm... is this what could change space-flight? Imagine having a material that is nigh weighless when moving away from gravity but gains mass again when moving towards it. It would make it much more feasible to transport heavier stuff into space.

They quote in the article that when moving in certain directions, the fermion's energy is completely derived from motion. So it's essentially taking the m out of E = mc², which is still neat, but not really something you can scale up
