The phrase “hardest query on the planet” refers to a query that’s extraordinarily tough to reply, typically as a consequence of its complexity, ambiguity, or lack of a transparent answer.
The idea of the toughest query on the planet has been explored by philosophers, scientists, and intellectuals all through historical past. Some consider that the toughest query on the planet is one that can’t be answered, whereas others consider that it’s a query that has but to be requested.
