The scientists had discovered the secret of mastering gravity, and anti-gravity, and harnessing it to their power. The core contains a small bio-mechanical device which appears to be a naturally evolved anti-gravity propulsion system. An anti-gravity platform equipped with a high-flight, plasma beam cannon. Well, air planes do work which proves. Inertial Propulsion and Other Delusions. Some ideas are so compelling and seductive it seems there will always be those who succumb to their siren song. We easily understand how transformative these technologies will be and can't help feeling that if we work hard enough, we can achieve them - the panacea, free energy, anti-gravity, and.
