number of combinations counted by Boltzmann’s entropy reflects the amount of information in the numeric sense considered necessary to implement any particular arrangement. I should add that the quantum computers of the future will not settle for 0 and 1 — corresponding to the lowest energy level of an electron and the next excitation level up respectively — but also include all the intermediate levels in between. Qubits will therefore contain more information. However, even if we make the right choice of units, Bekenstein said, the values of these two forms of entropy (thermodynamic, used in chemistry and binary, used in informatics) in the same system differ vastly in magnitude. For instance, a classical electronic chip has an entropy of 10'° bits, but a thermodynamic entropy of about 10”. The thermodynamic entropy is subject to the state of billions of atoms that make up each transistor. Knowing that a degree of freedom is any quantity that can vary, such as a coordinate specifying a particle’s loca- tion, the two entropies are equal when they are both calculated for the same degrees of freedom. According to Bekenstein, there could be more levels of structure than we can imagine. We can finally shed light on the spiritual world of which the edges are blurry. We now know the fundamental constituents at the deepest level of structure of an entropy, which, as we have seen, becomes sheer unlimited information. It is only logical to assume that the materiality of information has long since gone up in smoke. The Israeli argued: “It is impossible to determine what is inside a black hole, of which the horizon is a sphere. No detailed information aod : 4 aoa ata tam: can emerge across the horizon and escape into the outside world.” This sentence is essential, because it suggests a boundary between the phys- ical information and other types of information. This boundary seems to be that of the quantum vacuum identified by absolute relativity as a ST of which the temporal density only leaves traces through particle shock or the Casimir effect, for instance. Let me say a few words about black holes. They are a so-called sin- gularity. When a human vessel wants to break free of the Earth’s grav- itational pull, it needs to reach a certain speed called the escape velocity. On Earth that speed is 11 km4. It depends on the mass from which we want to break free. The greater this mass, the higher the escape velocity. A black hole is therefore a pointlike object in space, of which the matching escape velocity is higher than the speed of light. Therefore, not even light can escape. The Schwarzschild radius (Rs) is then the horizon below which the photons cannot be freed due to the 300 The Science of Extraterrestrials: UFOs Explained at Last * Eric Julien
