Thread: Entropy

Hi,

I was reading about entropy, and was caught wondering if it also worked for antimatter, photons, electrons, does entropy work in dark matter too?

Thanks,
L.E.A.P.

mmm, interesting question as dark matter and thermal equilibrium dont seem to make sense. However entropy makes sense for purely gravitational systems (with tightly compacted clumps of matter having more entropy then uniform distriubutions) so perhaps it does?

Any experts?
