Abstract: Tides created by the Moon on the Earth are discussed. A tidal wave slows down the rotation of the Earth. The Earth loses 3.3 TJ of kinetic energy every second. Almost all of this energy is converted to heat. However, a small part associated with the angular momentum is transmitted to the Moon. A formula for the efficiency of the transmitted energy is derived. It is proved that the efficiency is equal to the ratio of the following periods: day/month. The flow of energy from the Earth to the Moon is discussed. Its power and density are calculated: the power is equal to 100 GW and the density is equal to 1 mW/m2. The possibility that this energy is transmitted at the speed of light is discussed. It is shown that in this case the transferred angular momentum would be 17.5 million times less than the observed angular momentum. To reconcile the angular momentum transferred to the Moon with the equations of relativistic dynamics, the energy must be transmitted at a speed exceeding the speed of light by 17.5 million times. Therefore, the author puts forward the hypothesis that energy from the Earth to the Moon is transmitted instantaneously.
