Second Law of Thermodynamics

There is no conflict with the second law of thermodynamics and the behaviour of the universe.The history and development of the universe is not something which evolutionary biologists have anything to do with.You have been fed utter crap by whatever source you are using.I suggest you find out:1) What the second law actually says.
2) What the difference is between cosmology and biology is.
3) What sources to trust for information on such topics.

Yes, we are using up the available free energy.If you want to know how it is that there is a lot available I suggest reading "The Fabric of the Cosmos" by Brian Greene. He spends many 10's of pages explaining it in very clear words. (but it is still not intellectually simple.)

and what mark24 has said is why I opened with "crap" and a warning about being careful of your sources.If anyone feed me such junk when they had every chance over decades to correct it I would be inclinded to reconsider everything they had to say. There is a chance that at least some of the other things they are saying is also crap.We have now come back to your opening post PianoPrincess. Would you like to comment on what you have learned?

Yupe Buz that is correct. We have only so much time left. It may all wind down in only 30 or 40 billion more years.
