Dark Matter is Trying to get Smaller,and Heat wants it to Get Bigger Hmmm

What this heat is doing is creating countless collisions making for fast motion.by collisions and thus friction.Getting atoms to get slower moving atoms going faster and faster,and round and round she goes.Heat creating heat.. I think I'm thinking "Black body radiation" Can I say The universe radiation depends only the amount of its temperature??.OK if a BH has a temperature than Berkinstein was right about it having entropy.Let me add this thought BH give out no photons other than photons that can create heat.I 'm not saying thats 100% reality but possibly a good idea to think more on.Bert
