Where approximations need to be made in order to represent, the path may obscured yet remains. The question of repetition may arise in hindsight but does that then inform the present? If so, when the change does occur in order to inform, on what domain of knowledge?
PS. A comment came to my attention regarding outer space and my personal thoughts on it. I have no objections my only concerns as a ex Trekkie and Star Wars man is the principles regards to the unknown as here on Earth there does not seem to be any cohesive group that represents all humans that if it ever happens would be admirable to those from the final frontier.
This post concerns are completely earth bound!
