Ah - I love this question!! I've asked myself this very question countless number of times and needless to say have never arrived at any definitive conclusions - is there anything definite about time??? Time is not static, it does not stand still, it is always in motion. Perhaps, time can be looked at as a river - flowing constantly without a pause. Humans and other living/nonliving creatures can be viewed as debris in the river that are carried along, bereft of any power to do anything to resist, just being carried away with the flow. Scientifically, of course, we can measure time in seconds, minutes, hours, days, months, years, etc., but does that answer the question, "what is time?" Well, to me - it doesn't!! I've never been satisfied with any explanation of time I've heard thus far. It has been a fruitless search, albeit an interesting search!!

Along the way I've wondered about such interesting questions as, "Did time have a beginning?" "Would time end some day?" "Is time something tangible or an illusion?" "Do we just feel the passing of time, without it actually passing by?" I am sure I am not alone in wondering about such questions. I'd imagine there would be a lot of people out there wondering about the same questions!! Though some of the questions above have been explained scientifically, you wonder how definitive they are.  For example, we use clocks to measure time - but can any one of us definitively say that the time that the clock shows is the exact time it is supposed to be. It might, on the face of it, look like a stupid question, but is it really? We all universally agree on a time format and so we follow it - seems to me to be a matter of convenience than any definitive logic being there for it. Is there such a thing as "absolute time" or "the time?" Is there a "universal time?" Or, is time just an illusion?

The real debate is if time is absolute or predetermined or whether time is relative. Whether there is an eternal clock that keeps ticking by, irrespective of how we perceive it, or whether time is relative and depends on how we view it. Well, if any of you have bothered to read thus far, I wouldn't blame you for getting all tangled up trying to get your heads around this - I've been through it and haven't been any wiser at the end of trying to explain time!!

I am afraid though that I'am not done with time yet. One of the questions I wonder about time is whether time stops inside of the so-called black hole? Because, of course, even light can't escape from one of those phenomena. If the star that has become a black hole has an infinite of density and gravitation, what laws of physics follow inside of it - does (or can) time exist inside a black hole? Because, if we were to assume that time stops inside of a black hole, could it not stop in the whole universe too? Perhaps, in a big crunch (a debated theory of course, as most theories are)!!

Of course, if we were to think that time might in fact be continuing inside of black holes, we would have to wonder what kind of time that would be? Does that time exist independently of any other. You know, when I think of questions like this, I wish I were God (there's no harm in wishing right). I mean such interesting questions and no definite answers. Such exciting, tantalizing questions - that I so wish I knew the answers to. I love such questions - they are so essential to our existence as humans. I hope some day someone would find the answer to this question with an all-encompassing theory - I look forward to it! It is the greatest mystery ever!!
