Abstract:
Any body existing in a gravitational field that changes with time due to the expansion of the universe or for any other reason remains subject to a conservation law for energy and momentum, but with a new concept of conservation, which is the conservation of the sum of the different components of the quantity that represents energy and momentum, not the conservation of each component separately. With this concept, we find that the expansion of the universe is a continuous transformation of energy into momentum, there is no loss or gain in the total sum of them.
