Laws of the universe

In science, laws of the universe are regulatory equations, statements, or governing principles that are deemed to hold true in any part of the known universe or regions of space discernible to observation. One the first to make statements of two laws of the universe was German physicist Rudolf Clausius who in 1865 stated: [1]

“If for the entire universe we conceive the same magnitude to be determined, consistently and with due regard to all circumstances, which for a single body I have called entropy, and if at the same time we introduce the other and simpler conception of energy, we may express in the following manner the fundamental laws of the universe which correspond to the two fundamental theorems of the mechanical theory of heat: (a) The energy of the universe is constant, (b) The entropy of the universe tends to a maximum.”
