Trend of entropy of universe

  1. Aug 5, 2011 #1
    i was told that entropy of universe always increases.

    however i came across this text:

    http://docs.google.com/viewer?pid=bl&srcid=ADGEESh1KJo5csExQJgKwUMz73aHUhrrMqH0ag-md2J96bzb5pVWlx039lTKCSCXJB3e1Ns2nSgjqYetum_gM-cyJLGX7wLwBmjUB_MJOZEWvtAPKVoKM4gY83lYr1YIfG15wCVHxyYw&q=cache:W_MDM4qrtcAJ:www-teach.ch.cam.ac.uk/teach/IA/EE_student.pdf%20entropy%20decrease%20energy%20level%20spacing&docid=bb4e67973b4eb6ba159edd5a8ed4ff7d&a=bi&pagenumber=19&w=800

    so when the entropy reaches maximum at equilibrium, it will decrease?

    The link you've added is broken. The universe always proceeds towards the maximum state of disorder, in other words the energy available to do work always decreases (this is entropy). At some point in the distant future we will reach the point of maximum disorder and nothing will happen forever.
