Thanos is an odd villain in the universe. He travels to many planets in search of 6 infinity stones, magical gems that give their owner different super powers. Once he
obtains all 6 infinity stones, he places them in a glove, combining their powers. He uses
his new gauntlet to instantly kill half of the people in the universe. Is it logically possible
for Thanos to use the infinity stones to kill folks across the galaxy just by snapping his
fingers? Describe how we can determine if something is logically possible. Is it
physically possible for Thanos to execute people this way? Describe how we can
determine if something is physically possible.
