What would the universe look like if entropy did not exist? Random thoughts.
When looking for answers, this note should be useful to everyone. what is good and what is bad about entropy
Entropy is the arrow of time: With time entropy is increasing and free energy is reduced. Time is not reversible. Time is only moving forward. The time arrow points towards the future. If the entropy reduces arrow of time will point towards the past.
No chemical reactions: In the absence of entropy, the universe will have extremely high free energy. Both reactants and products will have the same free energy. There would be no chemical reactions or chemical processes.
All processes will be extremely slow: The irreversibility of a process causes entropy. Without entropy, the universe would be a reversible slow process in equilibrium with its surroundings.
No heat transfer from high to low temperature: Heat transfer takes place in the direction of entropy increase from high to low temperature.
Heat will no longer be a path function: Heat is always in transit because it is being chased by entropy.
No phase change: Entropy is a disorder. Because entropy always increases, there is a phase change. When water is boiled, it converts to steam because it can no longer accommodate entropy. To share its entropy, water moves to a higher energy state known as vapor.
That means there will be no steam and only low-energy hot water to do any mechanical work. So, no mechanical work.
No volume expansion: Without entropy, there would be no new microstate. The temperature would not have any effect on volume. Nothing will be compressible.
There is no thermodynamic work and everything is incompressible: Entropy is created when heat is converted to work. There would be no thermodynamic work if there was no entropy.
No equilibrium: There will be no equilibrium: all processes will be unidirectional. The human body is in balance with its surroundings. Entropy regulates our body temperature by making us sweat and cooling us down. In the absence of a place to dump the entropy, humans will experience significant increases in body temperature fluctuations.

?‘When S tends to zero at absolute 0 K, the universe becomes a point mass or you may quote as a "God particle" a state of perfect order.’

?“No entropy, then it will be similar to the universe without friction!
Entropy is the number of microstates, if no entropy then no waste heat, no waste heat so no processes, no processes then no activity!
Universe will stop working!

You and me and everyone will be no more!
Entropy is q/T, and for that to be zero, it would seem that q would have to equal zero!
Temperature is infinite...!! or ZERO HEAT...!!
(Infinite temperature i.e such high temperature which beyond imagination which is not possible, thus Infinite temperature is eliminated.)
That means there is zero heat in the Universe. Since heat is the end-product of energy loss, it would mean that no objects could condense out in this Universe, and since heat is also random kinetic energy, it would require nothing to be moving in the frame of reference of anything else (otherwise if everything has kinetic energy, the resultant motion will have randomness from the point of view of one of them).”

?“Transformation would not take place weather be reversible or irreversible. So, no movement would take place and no formation of by-products.”

?“No entropy for me, means no random motion in molecular level that means zero temperature and zero heat energy that means freeze of the universe.”

“I think there will be no heat and mass transfer, Work<->Heat processes won’t take place so no useful energy available to do work, no temperature changes throughout the universe which would negatively affect earth, no stability as processes and components comes into existence to attain their stable state due to entropy changes.”
Aashi Rathore
“Since entropy and energy are related to each other therefore no entropy means no energy, thereby leading to the end of the universe.”
Rizwan Yaseen
“No Entropy .... means everything is reached to its maximum possible attainable state.
To me there will be no amount of thermodynamic work will be available”

1 年Recently, while thinking about entropy and it's, shall I say, harmful effects -- like decay and death -- I began to ask myself several questions, primarily pertaining to death: Where did entropy (death) come from? Why was it created (or simply came into existence) in the first place, or would it have been created in the second place, with 'life' having been created first? (If death was created first, could life then be created? Or did life & death come into existence at the same time? Given that all 'things' have mass & energy [Einstein] -- even our thoughts and, independently, the thought, itself -- how could two 'things' occupy the same place at the same time? [Again, assuming, somehow, that both life & death came into existence at the same time, and not one before or after the other.]) How was entropy created? And, finally, What is entropy's purpose for existing? (Similar to "why" does it exist, but slightly different, as here I'm assuming entropy's future, not just it's present state of existence at the time of it's 'creation.')

1 年I think also that entropy is required in order to enable matter to form. It might be possible to prove this mathematically.

1 年Per a previous post: "What would the universe look like if entropy did not exist?" I get that without entropy there would be no thermodynamics--or chemical reactions--and, therefore, there would/could be no life or nothing living. But, since entropy describes the process by which all matter in our 3-dimensional space-time continuum deteriorates, decays, and--if living (has life-force)--dies, wouldn't zero-entropy mean zero-death? And, if there were no death, wouldn't life then be infinite--theoretically fantasizing that life could somehow still exist? Life without entropy? Eternal? Of course, it seems this notion would have to accept an entirely different approach to thermodynamics in an entropyless environment, which we could only imagine, but probably never know--truly understand--unless we were there.
