What got me thinking alone the lines of disrupting gravity was watching this video on Quantum Mechanics where they explained the various particles can be thought of as vibrations in particular fields. Those vibrations can transform into vibrations in the other fields, effectively transforming particles of one time into another.
If everything is vibrations in a field, then maybe there is a way to dampen a field. And if you can dampen a field then maybe you can dampen gravitation. And if you can dampen a field can you also amplify it and do so in a way that uses energy from other sources than your own.
Like a rock star uses an amplifier instead of just singyelling louder and louder.
Yes singyelling is now a word, because I just used it.
