Antimatter propulsion may be the only realistic path to interstellar travel. No other fuel source produces more energy per gram. When matter and antimatter meet, they annihilate completely — converting 100% of their mass into pure energy. That makes antimatter roughly 10 billion times more energetic than chemical rocket fuel and about 1,000 times more … Read more
