Assume the universe is a big spheroid, which will continue to expand outwardly away from the centre of the universe from time to time. The Solar System is a small dot within the universe, which will also move gradually outwardly in parallel with the expansion of the entire universe. As the Solar System is moving outwardly from the centre of the universe whatever within the Solar System would increase their universal gravitational potential energies at the same time is reducing its kinetic energy. In real-time, moon and satellites will continue to circulating around the Earth, as if, they will preserve their kinetic energies in the short term. This is because only negligible amount of kinetic energies would be transformed to the universal gravitational …show more content…
Undoubtedly, the Solar System which is on the edge of the Milky Way is believed drifting outwardly away from the centre of the universe in parallel with the expansion of the entire universe. The mother planet of Earth is subjected to radiation from the sun “everyday”, yet there is NO dramatic rise in temperature. This clearly suggests that as the Earth has increased its universal gravitational potential energy, the Earth improves its “appetite” for more “stationary” photons. Therefore, it is not surprising that in a “deserted” land on a moonless night would fill with “completely” darkness. Aids with atomic clocks, scientists manage to prove that the earth takes “slightly” longer than a fraction of seconds to make a complete revolution around the sun. There are two reasons that the Earth is slowing down. Converting more kinetic energy to the universal gravitational potential energy would slow down the Earth. On the other hand, the Earth is getting more “massive” as it has increased the capability to mop up more and more photons from its surrounding, especially, the Sun. More massive Earth would slow it down “gradually”. The same effect is imposed on satellites that are revolving around the Earth. Those satellites would also collect more and more “stationary” photons from the surrounding; therefore, they reduce their kinetic energies gradually as some kinetic energy has “diminished” to mobilize addition mass gained by the satellites, and some other kinetic energy would be transformed to the universal gravitational potential energy “gradually”. Most of the satellites don’t seem to lose their kinetic energies quite “dramatic”; therefore, the author agrees that it must be the interaction between molecules at upper atmosphere and satellites that could have slowed down the kinetic energies of those satellites at much faster pace than the effect due to the expansion of the universe.
