What is Time? Time is probably what people perceive as the clock, or a watch perhaps? They might perceive it as the "ticking" and "tocking" away of what we know as, Time.
But what really is Time? Is it something that exists in a parallel universe? Does it control our lives? Does it control our actions? Is it something that can be over-powered? Can we control Time? The answer most of us will give is a straight, flat "no". But what if we considered Time-control?
It would be beyong our wildest dreams! Being able to relive a happy moment or undo a fatal move... Yes, the luxury of Time-control or Time-travel is such a fantastic yet, unreachable destination... Or so we think.
If we could find a way to reach the speed of light, we would be able to travel back in time. But is this even at all, one bit, feasible?! If we cannot even reach the speed of Mach-12, why do we even need to think about reaching the speed of light? The idea of travelling back in time is not feasible now... But perhaps, not in the near-future however, scientists (you might be one yourself) might be able to find a way to reach the speed of light and sending people back in this "time-machine".
But what are the problems that might arise with the constant usage of the "time-machine"? Well, these are some of the possible factors/outcomes of the possible Future Scene:
1) The heavy reliance on the "time-machine" might lead to its abuse
2) The time-travel might warp time and this might lead to horrendous, irreversable changes in the events of Time
3) Crimes could be carried out via the "time-machine"
4) etc... There are many possible things that mgiht happen if there was such a thing as a "time-machine".
