comment How long would a lever have to be to move the planet Earth?
While I understand that the quote was metaphorical, a long lever would reduce the amount of energy needed to lift an object, Would it not? To raise a sphere with the mass of Earth how long a lever would be needed such that a human of average strength could lift it?
