Temporal extension of particles to interpret and intuitively describe quantum symmetries and related quantum and relativistic phenomena

The paper proposes the theory of temporal extension for fundamental particles as a key to intuitively interpret and understand quantum symmetries and related quantum and relativistic phenomena. While space-time as a principal world view is accepted and utilized in fundamental theories, certain traditional concepts of time have not been challenged before. Such a conception is the view that physical objects can only have a point like feature on the time line. When introducing a more space like quality of time, which allows the temporal extension for physical objects and particles, a fundamentally new world view arises. In this view quantum symmetries and certain relativistic phenomena become more intuitive to describe and deal with and "realism" gets a new definition. As a result the temporal length theory also offers to eliminate the tension between the nonlocality of quantum physics and the locality of relativistic phenomena. The paper provides a detailed description of the theory.
