They say Destiny is already written. If destiny is already written then can someone read and change it. Read the Future and then Re-write or Change or Control it. Writing my thoughts on the Sci-Fi (or real) concept where one (someone) can read, re-write, change and control the Future.
This idea or concept could be one day used as a story plot for a novel or a movie or a series with multiple parts sequels and prequels. We are aware of the concept of Light Years. New galaxies and stars are being discovered every now and then. They are many lights years away and some are billion light years away. There is a super/supreme power somewhere some (hundred or billion) light years away who created us. They know the future as they wrote it. As light is the fastest discovered stuff to travel, same way the future of ours are instruction waves started hundred or billion lights years ago. They are being transmitted regularly and we are receiving it constantly and acting accordingly. Till now we don’t have the knowledge to identify, collect and decode these instructions before they reaches us.
Concept
If such instructions exists and they travel from the far off world via space then there would be some way to identify them, interpret them, decode them and if possible change them. If such a technology is identified then the future can be known and altered. We need to understand what is going to happen in future and change the instructions reaching to us which is meant for us.
When these instructions come from the far off world they are amplified, transmitted and reflected through various stars, comets, asteroids, planets and satellites. When they are reflected through these then some properties of these get attached to instructions and some instructions get distorted/modified. That’s why we believe in sun signs, astrology, planets, sun and stars as a factor for having an effect on us.
Prequel
With this idea the plot begins. Since the beginning this is happening constantly with instructions been sent. There is no available knowledge if such a thing exists but just some rumors going on for last few millenniums (only). Accidentally in an unused/uninhabited area on planet Earth some centuries ago (in AD 1652), some of the documents and devices were discovered related to this phenomenon. Not knowing the significance of them these were ignored and left. Recently in year AD 2052 they were again discovered. These documents and devices have information on how to identify and decode them but not alter them. In the past, distant past, unknowingly these were altered for someone thinking it of as magic.
A group (from the other world) already knowing about this phenomenon have tried to identify, decode and change it for millenniums but have always failed. Whats happens in 2052 is protection of these documents.
Sequel
Scientists in 2052 come to know about such a phenomenon. They try to understand more on it and get some success. With the device only they come to know about the other world. The other world wants to control their future and all other worlds. This result in an inter galaxy war, saving the knowledge and protecting the future.
