Merits of using this propulsion system
• Efficient as 100 percent of mass of matter and antimatter is converted into energy
• It would allow the spacecrafts to reach the nearby stars and solar system in a fraction of time that is required by space shuttles using hydrogen-oxygen fuel
• Fuel required will be less as energy produced per gram increases
-Lack of antimatter substance existing in the universe.
Tether technology is the last propulsion technique we are going to study.
