Conservation of energy
Contents
General
The law of conservation of energy states that if no energy is supplied or removed, the energy of a so-called closed system is retained. Energy can neither be lost nor generated. Albert Einstein and other physicists of his time kept the law of conservation of energy high and derived a lot from it. The absolute theory, of course, also believes in the law of conservation of energy, even if it sees that the concept of total energy is controversial.
Einstein and the law of conservation of energy
Albert Einstein found out E = mc². Nevertheless, the statements on the law of conservation of energy are somewhat vague. In the end he sees m * c² only as rest energy, as E (0). Various energies must be added to this for the law of conservation of energy. For example, the potential and the kinetic energy of the energy conservation law of mechanics are added here. The absolute theory regards this as wrong, as that E = mc² is not only the correct description of the total energy, also inferred from the equivalence of space and time, but that it is also a maximum for the [ [Energy]]. Ultimately, the energy of mass and speed is put together to the square. Since the speed cannot be higher than the speed of light c, and the mass always remains the same, there cannot be any energy higher than m * c². Since then, as Einstein does, adding the potential, the kinetic and other forms of energy cannot be correct.
Energy and Absolute Theory
According to the absolute theory, E = mc² forms the total energy of a system. This also results from the equivalence of space and time, which Einstein also assumed when he said that in absolute spacetime everything moves with c. Kinetic and potential energy are only a part of this energy and not additive quantities. From this one can also derive the Conservation of mass, precisely from this equivalence of mass and energy. To assume for the law of conservation of energy that energy is higher than E = mc² is simply wrong.
Law of conservation of energy in mechanics
The mechanical energies of a system always remain constant with no external influence. So E (pot) + E (kin) = const. You can visualize this on the pendulum. When the pendulum swings up against the force of gravity, it gains potential energy, but loses speed, i.e. kinetic energy. If, on the other hand, the pendulum is at the apex, i.e. the lowest point of its curve, it really gains speed, and of course loses potential energy in the gravitational field.
Conservation of energy law and the first thermodynamic law
According to the first thermodynamic law, the energy is also retained. It says that the difference in the internal energy of a system is equal to the difference in the heat supplied minus the work given out. If both values are zero, as is the case in the closed system, the internal energy is retained.
Law of conservation of energy and the universe
The law of conservation of energy can and is also applied to the universe. The big bang theory believes on the basis of the law of conservation of energy that all energy must have already been present at the Big Bang, so that the point that arose during the big bang is super hot and with almost endless energy was. This energy then gradually spread throughout the universe. The absolute theory also sees another possibility, namely that there are positive and negative energies and that these are balanced and accordingly the energy of the universe is equal to zero. Of course, if you add up the amounts of energies, the energy is very high. But a total energy of zero would have the advantage that you don't have to worry about what happened before the Big Bang. Here the energy was also zero and the amounts of energy were also zero. That was nothing.
One could even go so far that the big bang theory in its current form almost violates the law of conservation of energy, but suddenly an infinite energy emerged from the energy zero, which is a clear violation of the law of conservation of energy. The assumption that the laws of physics only emerged with the Big Bang should not be acceptable to a theorist.
