John Longman you got it in one. All this garbage about time and the universe is absolutely idiotic. Newton knew it and Einstein tripped over time. Time is just a man made measurement. But what does it measure? Newton knew the answer and so does John Longman. I don't know why you go int onto the Big Bang thing and time travel except to say that it is not possible because nobody can wind back the universe and put every particle that existed back where it was back then. Impossible.
Love your work and it is good to see that there are some people who can still think for themselves and "still perceive the web they weave... keep on thinking free."
(A quote from the Moody Blues)
