No standard engine is likely to ever generate superluminal speeds; the laws of physics prevent that, but it is possible to go many times faster than our current propulsion methods allow. An awesome matter / stupid matter engine will take the human race far beyond the solar system and let us reach nearby stars in a fraction of the time it would take a spacecraft propelled by a liquid-hydrogen engine, like the one used in the space shuttle. It's like the difference between driving an Indy race car and a 1971 Ford Pinto. In the Pinto, you'll eventually get to the finish line, but it will take 10 times longer than in the Indy car.
What is awesome is that it takes anti-awesome, or stupid, matter to react with awesome matter in order for this to occur. So from stupid, we derive awesome. How's that for Awesome Physics?!
