Beginning about 13.8 billion years ago, the story of the past is a coherent record that includes a series of great divides. Beginning with the Big Bang, History is an evidence-based account of emergent complexity, with simpler components combining into new units with new properties and greater energy flows. The access to high-quality energy in certain pockets of the universe has permitted increased complexity in relationships between quarks, atoms, molecules, cells, animals, and humans within families, cities, nations, empires, and the world.

The total energy of the universe is a constant.

In Isaac Asimov “The last question”,   tells us about the creation of super computers called multivacs. Through the course of seven historical settings, beginning in 2061, the question   "Can the workings of the second law of thermodynamics (used in the story as the increase of the entropy of the universe) be reversed?”  is asked to the multivacs in increasingly powerful iterations. And to each of these the answer is   "INSUFFICIENT DATA FOR MEANINGFUL ANSWER."

The second law of thermodynamics states that in a closed system entropy always goes up, which means very roughly that everything that arises from order — galaxies, stars, metals, planets, air, water and life — will eventually be dissipated into chaos. By 'order' what is meant is organisation, structure and function: the opposite of randomness or chaos. Unless humanity manage to produce energy – without increasing entropy — efficiency will always be a problem to be solved. The calculation problem will keep haunting even the most robust programs of “post-scarcity economy”.

— Heat naturally flows from higher temperatures to lower temperatures. — No natural process has as its sole result the transfer of heat from a cooler to a warmer object. — No process can convert heat absorbed from a reservoir at one temperature directly into work without also rejecting heat to a cooler reservoir. That is, no heat engine is 100% efficient.

Entropy is the problem of the universe. It’s death sentence. Economics and politics are expressions of this problem. The palliative solution so far has been to optimise entropy dissipation, but at some point, if something else isn’t found, heat death will reach even the highest of the negentropic towers.

— Any process either increases the entropy of the universe - or leaves it unchanged. Entropy is constant only in reversible processes which occur in equilibrium. All natural processes are irreversible. All natural processes tend toward increasing disorder. And although energy is conserved, its availability is decreased. — Nature proceeds from the simple to the complex, from the orderly to the disorderly, from low entropy to high entropy. — The entropy of a system is proportional to the logarithm of the probability of that particular configuration of the system occuring. The more highly ordered the configuration of a system, the less likely it is to occur naturally - hence the lower its entropy.

The total entropy of the universe always increases.
