But by doing that will we really succeed? Time is a unidirectional quantity and it'll always move forward. Einstein's theory of relativity states that in order to travel back in time one has to travel at a speed faster than light. But to accelerate a mass to that speed would require infinite energy which is not possible. Therefore time travelling is considered impossible. To travel in time one has to somehow curve the space-time. But, let's now say that somehow you found a way to break time barriers and decided to go back in time and change something. When you will land yourself in the past, the past will already have a version of you.
