Super Universe
Defender of God
Essentially, for humans, the future cannot change because it has already happened. If you were to learn about the future and then perform some action or non-action then it would be in accordance with what already happened on the original timeline.
Now, it is possible to develop technology that allows beings to go back in time to specific intervention points and view the past but they cannot affect any change. They can only view it as it happened.
Souls can, however, access the original timeline and change things. This creates a new timeline while the original timeline remains unchanged.
If, somehow, beings developed the technology that allowed them to not only view the original timeline but also affect change in it, well, they would immediately get the attention of some extremely powerful beings who would certainly intervene.
