I have a problem understanding how you arrived at the figure of eight or nine teratons for the antimatter container. Earlier Fritz stated that each container held between fifty and one hundred kilograms of antimatter. One hundred kilograms of antimatter will generate a 4.3 gigaton blast when it comes in contact with one hundred kilograms of normal matter. Your statement is on page two of chapter thirty one. When Fritz gave the estimated weight she also gave an estimate for one gram of antimatter. She gave a figure of “more than forty kilotons”. That estimate is correct. Somewhere the estimated weight of the antimatter increased by a factor of two thousand. Have I missed something? ]]>
