1. Supposing we had many thousands of antimatter bombs (they can be detonated in many different locations), how much total antimatter would we need in order to wipe out all humans on Earth?
2. Supposing we had one antimatter bomb (it has to be detonated in one particular location, but it can be as big as necessary, even as big as an entire city), how much antimatter would we need in order to eradicate all animals on Earth?
3. Supposing we had one antimatter bomb, how much antimatter would we need in order to completely blow up the Earth into millions of pieces?
