CAN TIME BE CHANGED????

We all have certain moments in all our life which either we want to relive or change something in it!!!! It can be a mistake or someone's death. Well firstly, according to theories time travel is possible if we can travel at a speed more than light, but it's all in the theory!!!

Even if time travel was possible it will have its own consequences....

For example a kid who lost his mother in an accident at the age of 9 years. He studied hard, lived a disciplined life and became a scientist who made a time travel machine. He goes back and prevents his mother's death, the twist is when he comes back to his time, reality is something different...He was disciplined in the earlier timeline but in the changed timeline nothing odd/wrong happened with him and he didn't become successful and with the change he got in the timeline he had started loosing his memory. Changing time or a small event can bring many changes in our upcoming life.

Even if time machine was created and I had it, I wouldn't dare to bring a change in the past. It's consequences are unknown.
