Physics - a story about how information is -conserved and -transformed

While we are working with physics, we want to believe that everything is in the reach of our undersanding. That there exists a truth about things that we can share and that nothing can be an explanation of itself; the world is open for us to experience euphoria of discovery - there are exciting, important and new excitements waiting for us to make discoveries.

For a physicist this means that there are persistent things (which we experience as information) and transformation laws between different incarnations of the persistent things. Nobody disturbs our ability to comprehend by inserting information to a closed system and no demon can either take it away; that is how we believe because our very existence builds upon the assumption that we can understand. 

Relying on our belief in our ability to undestand we have discovered many laws of physics where the information is maintained and transformed to other different formats. There exists the conservation laws for energy and impulse and there exists the conservation law for electric charge and many others. Above others is of course the law of conservation of information itself - the amount of information is preserved in a closed system that is in the reach of our comprehension; we believe in this because the very existence of us depends on it, that we can understand the structure (information) in our environment and that the laws of transforming this information into other forms are universal and same for all viewers.   

What is a closed system that is in the reach of our comprehension? At least all constant velocity systems measure the amount of information and the laws of transformations in the same way. Acceleration means that we get more information from our environment; we are pushed by photons or we are forced by an external force to something new. But at least constant velocity systems will experience the information and the laws of transformation in the same way.

We have actually said already fairly much already. We have claimed that:

• there exists a law of conservation of information (information bits according to the language of engineers) that states that the amount of information will be conserved in a closed system that is in the reach of our comprehension (we have to remember that part of the information is transferred to us always when we make an observation)
• Information can transform into new formats; move to other positions, but only through laws of physics that are same for all viewers that have a constant velocity. This is because we believe that we are all able to understand the world in the same way - we can share our experience with each other and create a jointly agreed truth 
•  energy (mass) is at least one format of information (a combination of impulse and energy according to the general theory of relativity - to be precise)

Is this universe created for the sake of humanity? Are the laws of physics created so that this will happen - just to make it possible for humanity to exist? I would like to answer that no - this universe is not created because of us. We just happen to emerge into this particular slot in the chain of mathematical models that the universe is about. We emerge here because our universe happen to provide a context where we have the possibility to understand (creating a model of the environment) and discuss (all viewers seeing the same "reality").   

Our considerations about what it means that the physical world is in the reach of our understanding - and how the laws of physics reflect this principle - and how these are translated into conservation laws for different forms of information, opens us beautiful and wide perspectives. Physics is a science that studies the laws of conservation of information and the laws how information is transformed to different places and formats; it is one of the most fundamental methods for us to understand our place in the universe.
