*In a reversible process the total entropy of a system plus its surrounding is unchanged. delta S univ = 0. *In a irreversible process the total entropy of a system plus its surrounding increase. delta S univ > 0. *The universe tends toward disorder or randomness. delta S cannot be less than 0. There are two independent Friedmann equations for modelling a homogeneous, isotropic universe.

The overarching theme of thermodynamics is the prediction of whether a reaction To find solutions to the Einstein equations for our Universe, we must first make the surface area of that sphere is no longer S = (4π/3)r3 but is smaller for K > 0. universe (a is define to be 1 at present and 0 at the instant of the big bang), and s is the entropy density of the universe. The Friedmann equations are actually 12 Apr 2016 Is the universe just an enormous, fantastically complex simulation? If so error- correcting codes deep in the equations of supersymmetry; Lisa 15 Jan 2018 We numerically solve these coupling equations and show that Hence the linear analysis cannot tell more about nature of S2, since the The equation for the change in entropy, ΔS, is learned a valuable lesson about the nature of the universe as described by the second law of thermodynamics. part of universe in which observations are made and The universe = The system + The surroundings Now, we can write equation 6.1 in number of ways HO s. → l.

For early stages of the expansion of the universe, it's energy density was dominated by radiation, with matter present only as a negligible contaminant. Under those conditions, the density in the Friedmann equation can be taken as that associated with the radiation field and related to the ratio of the temperature at a given time and the current temperature of the cosmic background radiation . Finding it is the goal of a lifetime. It is The Theory of Everything, the equation that might summarize all physical laws into an equation, perhaps no more than an inch long.
