Living systems can not be closed systems or they are not living. Does evolution violate thermodynamics TLDR: Evolution does not violate the Second Law of Thermodyamics, because Earth is not a closed system. How do the laws of thermodynamics apply to living organisms The First Law says that energy cannot be created or destroyed. No The Second Law of thermodynamics applies in the truest sense to closed systems. Human organisms are not a closed system and thus the energy input and output of an the organism is not relevant to the second law of thermodynamics directly. The only known closed system that exists is the entire universe and thus the law applies to the universe as a whole. Explanation: The second law of thermodynamics postulates that the entropy of a closed system will always increase with time (and never be a negative value). Do living organisms obey the second law of thermodynamics? No known phenomena violates the second law of thermodynamics. If we just shake the board to reposition the pieces, then clearly the system of board and pieces are not isolated, so the Second Law does not apply. Imagine that, like Conway in 1970, we are playing the game on a checker board (actually Conway used a Go board). The apparent order in living thing is the result of transporting entropy. This system does not violate the Second Law of Thermodynamics. All chemical processes in the body create entropy. The second law of thermodynamics is because its not applicable to living organisms things living organisms are not a closed system. As long as life creates entropy, it follows the second law of thermodynamics. Does life violate the second law of thermodynamics Quora?

Any of these laws can't be deduced from others i.e. It is always possible to find contrived examples in which the entropy does not go up or even goes down, but those are just statistically unlikely to happen.Originally Answered: Is it possible to violate second law of thermodynamics? NO ! The laws of thermodynamics (zeroth, first, second and third) are not mathematical in nature i.e.

This could be the case, it's just extremely unlikely that the initial conditions of the universe would allow such a thing to happen.Īs said above, the fact that entropy goes up is just a statistical effect. If such a configuration does exist by the way, the problem isn't really specific to closed timelike curves : the timelike cylinder has a causal universal cover (it's just Minkowski space), in which case we simply have the same field configuration repeating itself over and over in time (a lot of closed timelike curves have that property that they can be unrolled into causal spacetimes like that). Not all initial conditions are allowed in a spacetime with closed timelike curves, as otherwise they may not provide any time evolution which is consistent, so in this example any field on that spacetime will be required to evolve with a cyclical entropy (it is quite likely, in a realistic case with interacting fields, that no such configuration exists, hence why closed timelike curves are probably not a big worry). The second law of thermodynamics can be written as an equation of motion to describe evolution, showing how natural selection and the principle of least action. This is one effect of closed timelike curves called retrocausality : the evolution of system is influenced by future events. This is not very surprising because we do require all measurable quantities to be the same as identical spacetime points and thus by continuity they have to be thusly along closed timelike curves. The simplest example in those cases (and the oldest, too) is always the timelike cylinder, defined as $M = \mathbb(\rho \ln (\rho))$$Īs $\rho$ depends on the quantum state, it is easy to see that it will itself be cyclical in time, meaning that $S(t) = S(t+T)$.
