I wanted to make this post in the Post your short questions here. No need to start a thread everytime. thread, but it seems to be mostly about moderation and site maintenence. I am hoping to get more of a "concept check" from other, more knowledgable members.
"The second law of thermodynamics ... is an expression of the fact that over time, differences in temperature, pressure, and density tend to even out in a physical system that is isolated from the outside world." Wikipedia
"Every energy transfer or transformation increases the entropy of the universe." Biology 7ed. Campbell, Reece. 2005
If the universe is slowly falling into disorder as I understand the 2lotd to mean, does this concept impact the ideas of an ever expanding / neutral / or "Big Crunch" universe? What I mean to say is - does the 2lotd contradict the idea of Neutral or "Big Crunch"?
If the universe is supposed to always have a net result of disorder how could it eventually collapse back into a singularity? or even remain neutral?
This is not an "EvC" related question, but its 5 a.m. and questions like this pop up and ruin my chances for sleep!
