Timeless fascination with Time

Where does time go?
More importantly, where does it come from?
Or did Virgil make a more acute observation…
"Sed fugit interea, fugit inreparabile tempus"
Time meanwhile flies, never to return
I have been thinking about this lately and I don’t know exactly how to cover the topic. Should one consider the scientific theories? Or does philosophy offer a more plausible explanation?
Time has always fascinated people. I remember watching H.G. Wells’ Time Machine on TNT starring Rod Taylor and later I read the book as well. H.G. Wells wrote this novel in 1898 which shows that the power to go back in time has always fascinated people. Most of us have, at some point in our lives, wished to turn back time and make sure that our lives turn out otherwise. So then, what would the status of present be if this was possible? Will it still be a factual & autonomous facet of truth or will it be subjective to relevance? And what will the tense be in such a situation? How then, will we determine the degree of pastness, presentness and futurity?
And should man have the ability to turn back time?
And how then will time be quantified? Aren’t there moments that seem to last for days and years that just go by in a blink?
And then, how is eternity defined by time?
Isn’t forever composed of nows?
And don’t our passions expand time by making it worthwhile whereas a purposeless life only makes time a burden?

All I have are questions….
