Does being under or on water provide any protection from an asteroid hitting the opposite side of the Earth over being in or on land or in air? Why?
Will the shock wave follow the curvature of the Earth through the oceans?
I'm trying to go with the worst case survivable scenario.
This is from a broad question that I am breaking up in 3 questions. Feel free to edit.
Scenario 3. In a submarine or capsule underwater?
Does being in the air provide any protection from an asteroid?
