The first law of thermodynamics is simply a statement of energy conservation. That is, it states that energy can always be accounted for, that the energy of the universe is a constant - it can be transferred between objects and can change form, but the total doesn't change. But the first law does not preclude things occuring that we know do not occur: A glass of water does not spontaneously separate into ice cubes and warm water even though the energy balance equations used in calorimetry problems would allow it. That is, energy conservation - the first law of thermodynamics - would allow for the possibility that a system in thermal equilibrium could separate into two systems - one at a higher temperature than the other - and that temperature difference could then be used to drive a heat engine to do work. The second law of thermodynamics explains why the universe does not work that way. It articulates the underlying principle that gives the direction of heat flow in any thermal process. The result, of course, fits our everyday experience. The second law states the reason why it is true.I already did it earlier in this thread, just because you ignored it and are too lazy to go back and read it does not require me to post it again.So, then you can't provide a link to anything you claim.Well, I already gave you Hawking for the first, and the SLoT covers the second and third questions. Entropy is greater than OR EQUAL TO zero.Is it your belief that the total entropy of the universe is decreasing? Do you have any credible source for that belief?You keep repeating the same thing, which will not explain how the oldest and therefore most entropy laden matter is accelerating away from us.The problem with a cyclical universe is with the 2nd Law of Thermodynamics. If it is a periodic universe then the entropy will increase with each cycle. The 2nd Law of Thermodynamics is a fundamental law of nature which tells us that entropy can only increase or stay the same. Entropy can never decrease. Which means that in a finite amount of time, a finite system will reach a maximum state of disorder which is called thermal equilibrium and then it will stay in that state.
You need to see the universe as a perpetual commotion machine with an entropy of zero.
Do you believe that the total entropy of the universe never decreases? Do you have any credible source for that belief?
Do you have any credible sources for any of your beliefs?
Entropy increases in some local parts of the universe and decreases at the extremes, as shown by the acceleration of matter at the extremes, giving the total universe an entropy of zero, consistent with the SLOT.
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.
