Precocious young physicist Aisha Mustafa just patented a new system that could propel spacecrafts to the final frontier without using a drop of fuel. In short her system taps one of the odder facets of quantum theory, which posits that space isn't really a vacuum. It's really filled with particles and anti-particles that exist for infinitesimally small periods of time before destroying each other. Mustafa thinks she can harness them to create propulsion, resulting in space craft that need little-to-no fuel to maneuver around in space. Fast Company reports: Mustafa invented a way of tapping this quantum effect via what's...
