How much destruction would 10 kg antimatter do?
Correction Made: Well then, assuming this source on national geographic was giving a fairly accurate number, and considering the Little Boy bomb had a yield of 13~16 megatons of TNT, then doing the calculation here, the yield of 10kg of antimatter is between 348214.29~428571.43 megatons of TNT. The largest explosion I have witnessed was approximately 450 megatons of TNT, and it quite resembled a considerable nuclear blast, I would say 10kg of antimatter would yield a physically destructive radius of 53571.43 miles. Given the equatorial diameter of the Earth is 7926.34 miles (and assuming the blast was created on Earth), the blast would be enough to destroy Earth, but leaving the moon intact, as the blast radius would fall between 180243.03~192132.62 miles short of Luna. Of course, due to the loss of a gravity source in addition to the force of the blast itself, the moon would be flung out of the solar system, possibly finding a new home, or destruction.
