E fit be 1 - 20 sentences. Context: <response>: Mach argue say, for inside empty universe, the water experiment go remain flat. But if another object enta dis universe, like distant star, the bucket fit dey rotate relative to am. The water inside the bucket fit get small curve. To explain the curve wey we dey see, as we increase the number of objects for the universe, e dey increase the curvature for the water. Mach argue say, the momentum of an object, whether e dey rotate or dey move straight, e dey exist as result of the sum of the effects of other objects for the universe (Mach's Principle).
