In physics I was taught that energy is not a substance and does not have a definite location. However relativity says that energy is/has mass. Mass does have a definite location. If energy is mass, how can it be and not be in a definite location? If energy has mass, where is the gravitational field caused by that mass if it has no definite location? Dan
