It is more likely that a it exists than does not exists considering the physics. You would not be creating free energy, you would be drawing from a limitless supply contained within space itself. See recent developments in dark energy and particle research. There is more energy in a small section of space than all previously known energy in the universe....by a great order of magnitude...in theory.
My point is the rabbit hole is getting deeper and wider and exponentially more extraordinary by the day.
Simple geometric exploitation of the vastness of our universe, one which contains mathmatically anomalies such as pi, will likely seem elementary in the future.
My point is...its not IMPOSSIBLE.
