is the origin of the universe implicit in the second law of
thermodynamics? If entropy increases over time, there must have been a
time in the past when there was zero entropy.

Yes, a time in our space, time continuum when things were perfect. Similar but different to the un-caused cause. Or, all intelligent messages require an intelligence to send the message e.g. the inherent design and intelligent information encoded in the DNA. As entropy is devolution and a loss of information, then there must have been a time of perfect information - but not of no information.
ReplyDeletehow does lack of entropy imply perfection? Perfection for/of what? The zero entropy universe was - as far as I understand it - a singularity. Not much good for anything on a human scale - shortly after it ceased being a singularity it was trillions of degrees hot and no good for sailing, cycling, growing vegetables or raising kids and chooks. DNA is the result of billions of years of evolution that could only occur once the universe had gained sufficient entropy to allow stars to form, explode and reform enough times to generate the atomic elements necessary for building complex molecules. Post the formation of the first self replicating molecule, natural selection is the only designer required to come up with vast complexity of life on earth. The notion that evolution is a random process is true only in that random mutations occur in every generation. Nearly all of these are eliminated by natural selection, the few that persist have been filtered by the strictest of criteria: survival and hence, fit beautifully into the environments in which they are found. So beautifully that they appear to have been designed to fit and they were; by natural selection.
ReplyDeleteWilliam of Occam came up with the idea of not multiplying parameters beyond necessity and I don't see any need to multiply the fact of dna by invoking any force other than those described by Charles Darwin 150 years ago and since verified by endless experiment and proven via the predictions the theory makes which concurr with observation. Predictions such as being able to use dna to trace the origins of homo-sapiens to a group that left Africa around 50,000 years ago, spread east through the last ice age, reaching Australia 45,000 years ago and Europe nearly 10,000 years after that. All that is in the dna record as well as the approximate time when we parted company with the ancestors of bonobos and chimps (7 million years ago) and so on back for over 3 billion years.
Back to the first self replicating molecule - I think science will solve that, I think it is close.
And the big bang... I have great hopes for the Large Hadron God Detector.
