Why, then, are we not utilizing such an amazing device. This has profound implications which cannot be ethically ignored. At least the Air Force must know. There are indisputable sightings of anti-gravity aircraft every single day in the U.S., and groups set up to record and analyze this data. As far as I'm aware, this concept was not presented by anyone at the Breakthrough Propulsion Physics Workshop in August 1998 at the NASA Lewis Research Center.
Gravity actaully changes the shape of space.
This is why a rubber sheet is often used to depict the way gravity works. The medium is warped so an object traveling along follows a curved path. With current advances in computer technology, surely we should be able to produce an automated explorer who is immune to the adverse effects of microgravity, vaccuum, and solar radiation, etc. The loss of such an explorer would be a mere set-back, versus a tragedy for the program. This robotic pathfinder would also be able to send back data which would help us determine if the risks and cost of a manned mission to a celestial body would be worth the investments of time, money and human life.
