Greetings Prof. Hendry,
following the recent experimental confirmation of gravitational waves (congratulations!), I've been wondering if it's theoretically possible—given our current knowledge—to alter the curvature of the space-time and by extension gravity without the usual means based on Newton's law of universal gravitation (e.g. centrifugal force or a massive object), i.e. using some form of energy.
Note that the local effect that I have in mind would be as small as a single person or even smaller, so we could jump higher or explore planets much more massive than Earth, or effortlessly lift a bloody grand piano that needs to be moved through the window for a hefty price (I'm sure you can imagine the great potential of altering the space-time besides FTL travel).
Thank you and good luck with your future endeavours!
