The author mentioned an Earth made from antimatter. How about a spherical shell of gaseous antimatter, whose total mass is equal to Earth? Make Earth the center of this sphere, then wait.
- _kst_ 10y agoThe matter-antimatter annihilation near the boundary would generate enough energy to blow the antimatter shell into deep space (where it would cause some serious problems for the rest of the Solar System). The released energy would likely (I haven't done the math) be enough to vaporize the Earth, which would meet the original requirements, but I don't think it would annihilate a large percentage of the Earth's mass.
