It sure looks that way. The thermodynamic state of 'maximum entropy' is one in which there are no longer any temperature differences, and presumably only the simplest states of matter are present. Protons are more 'complex' than their individual constituents.
Stars are more complex than an equal amount of gas dispersed to 'infinity'.
Given enough time, the universe seems destined to evolve into a very diffuse state with an average temperature near absolute zero. Then again, the universe may recollapse in 100 billion years without ever achieving the maximum entropy state. Dr. Sten Odenwald Return to Ask the Astronomer .
