When I listened to the famous song of the famous jailed musical act, Robert Kelly, popularly known as R.Kelly, If I Could Turn Back The Hand Of Time. What comes to mind is the ability of man to make mistakes and either live with it or move to the next phase or chapter of life. The question of if Time Travel is possible brings a lot to the fore. Time travel could be simply described as going back into the past to correct one anomaly or the other beside the consequences an action has brought. Such an action may not be intended but turned out to be a bad blood or effect.
If I was asked, I would rather let life go on irrespective of the mistakes that have already been recorded, only that one would have to learn from such mistakes and avoid repeating the same. As a child, I learned not to play with fire because I burnt my finger while I toyed with candle light. I needed none to tell me to stay clear from fire after that experience. Such is life. We should take responsibility for our actions and live with the consequences. That makes us humans in the first place and reasonable enough to drive the right things. As we know, whatever anyone does has consequences or rewards.
However, I would not bother to consider time travel for the following reasons.
First and foremost is that history would be distorted when time travel is possible. History itself is a record of past relevant events. For instance, there are medical records which refer to medical history which enhances progress, treatment and medication of an individual. Time travel will sort of alter history and result in confusion of human development. Since history is very important to human life for planning and managing events as they occur, it is important that we keep our history and hand it to the next generation and not to distort it. Hence, we would not be in support of time travel.
From the above, if time travel is permitted or real, then it would hamper human development a great deal. Humans may find it difficult to make research or discovery as time travel would always be used to change what has been done. This is the reason time travel should not be encouraged. The human species is driven by the name or titles. Since the day of Isaac Newton, Michael Faraday and others, people have joined the train of building household names through hard work which dignifies and puts them on a pedestal like the frontline discoverers, researchers. Time travel may put a stop to the desire to do something extra-ordinary.
For selfish reasons, human nature may use the time travel opportunity to make their personal longings which may not always be pleasant to their advantage and the disadvantages of others.
Come to think of it, life may never have essence when time travel is made real or activated. Nobody may end up growing and getting old and dying. It is true that life may be endless for individuals but the consciousness that everything ends one day may not be there again. The fact that life starts and ends gives man the consciousness to do what is expected of them knowing that time is not on anyone's side.
