We would be long gone. Can you imagine what a football-sized (or even bigger) antimatter meteorite would do?

Hint: six to seven grams of antimatter is the equivalent of the bomb that took out Hiroshima.

6 to 7 grams? No. 1/4 of a gram of antimatter reacting with 1/4 gram of matter is just about the right mix. That’ll be around 15 kilotons.
