It's fun to think about what this could mean. Can you defeat gravity by somehow energizing matter to affect its spin and acceleration? And if so, could this not only be a technology for space travel, but potentially be an explainer for something like dark matter - maybe there are parts of galaxies that are energized differently than we assume, thereby affecting their gravitational pull?

I'm sure this all sounds dumb, I'm not a physicist, but it's fun to think about.
