2nd law of thermodynamics argument
Hello everyone. I am a self-described Atheist. Recently I have been attending meetings of our church group on my college campus. They have been hosting weekly sessions where they show videos from a series titled 'The Truth Project' which is a well produced and obviously well funded lecture series in which a christian apologetics 'professor' supports Christianity as academically valid. I was curious about the arguments that Christians might have so I thought that I would learn a little bit more about it.
I have been through about 5 weeks now, and am surprised by how convincing some of their arguments are. The one in particular that has been frustrating me is their argument about the 2nd law of thermodynamics and the entropy of the universe. They state that our universe is slowly reaching an equilibrium in which heat will spread out across the emptiness of space and create an even temperature which is too low to support life. They argue that this indicates that the universe must have infact had a beginning and that it is impossible for the universe to have simply always existed because the universe would have reached this equilibrium by now.
I am no student of astrophysics, and when I am presented with this argument I don't know how to respond. Is this true? Does science indicate that the universe is slowly reaching an equilibrium with no hope for the recollection of matter and energy to cause another big bang? Is it true that science indicates the universe had a beginning?
What does this mean?
