Time and Timeline

Tick...Tick...Tick...Tick... Its running. What is 'it' here? Any educated person who had seen clock says it is time. When somebody asks me 'What is time?' (I used to look at my wrist earlier, now) I look at my phone to answer it. It was alright till few theories and articles of physics spoiled my mind. One of which is 'The brief history of Time' by Professor Hawking. Questions such as : did I address the question of 'What is time?' properly by looking at my clock, Is that what that person was seeking from me? - never raised earlier. By looking at the clock I see its the clock running not the time. By looking at the count down at a traffic signal I see its the countdown running not the time. These are actually measures getting mapped to time. Then what exactly is time in my view? Read on..
Imagine a perfectly spherical ball on a perfectly flat ground staying at rest. Imagine a small supporting component which elevated the ball to few centimeters high in altitude. Suppose if a golf player hits the ball in parallel to ground, the ball start flying in parallel to ground with maximum velocity in the beginning but sooner it slows down. It slows down because there is gravity which pulls down the ball and opposition by air which resists to give way. As gravity pulls down the ball slowly tends to come down, when one face of ball touches the rough ground, it is felt pull back due to friction while the rest other parts are continuing the initial movement which gives a revolving motion to it. Let us suppose that we set up an ideal place to conduct this task again. Suppose there is a line one side of which there is gravity and other side of it has no mass and no gravity(a complete void). Imagine the same old player hitting the ball placed at the edge towards void side. The ball keeps moving in the direction of force and continues to move in its initial pace since no other external force acts on it. What if the direction it is advancing has no obstacles at all and no boundaries at all? It goes on and on and on as time goes on and on. Is it what the time like? If yes, then what precisely is the time here – the ball, its path, its current location or its direction? If only one of the aforementioned choices are true, what are the others?
Though I haven't found accurate answers for my previously mentioned questions, I am approximating few answers to pave my way to another curious yet interesting task. I presume that the 'Time' in our discussion is the ball in our previous experiment. It is moving. It is also running. It has no obstacles to hit and stop. It also has no other external force to alter its speed. Apparently if the ball is not messing with any other entity then it leaves no footprint or mark. Imagine an imaginary silencer at the back of the non revolving yet advancing ball which emits colored non diffusing smoke. Now we can see the path taken by ball. Let us call this path as 'TimeLine'. So the Time leaves our imaginary 'Timeline'. The path behind the ball is 'History' and the path it might take as it proceeds is 'Future'. I honestly do not know what is target is and who hit the ball. Leaving aside prediction of future path of ball but get hold of 'History', lets try to bring you and me into the path.
You, me, everybody has a lifeline which is the line segment in our imaginary timeline connecting the point where birth happened with the point where death would happen. Our enjoyments, studies, works, family life and everything else comes in between these two points in time. This tiny segment is duration of our lives!! Jesus Christ's life segment is nearly 2000 years earlier to us on the same timeline. Pythagoras, Euclid and other Greek nobles time lifespan is much farrer than that. The past timeline has witnessed glorious empires, merciless wars, amazing personalities and mind-blowing discoveries. I am after the problem of bringing all of these goodies and baddies and their actions virtually into a system as simulated entities. I am after the problem of making a computer to know complete history instead of saving narrated history as zeros and ones. Wish me best!!
