The classical understanding of time as a concrete element is under scrutiny as well. Time is flimsy in the special theory of relativity. In quantum physics time can be symmetric and have two directions. In Maxwell equations there is no built in arrow of time. The notion of time is a mystery at this time.

Once solid and local particles of classical physics, nowadays are distinguished as zero size specks that at times are waves and extended to the boundaries of the universe. The fundamental elements which built the background of classical physics are under serious scrutiny.

At the beginning of twentieth century when physicists were faced with quantum mechanical paradoxes, futile attempts were made to explain them in classical Newtonian terms. Hidden variable theories were introduced to explain the puzzles within classical paradigm boundaries. In 1964 John Bell showed that all local hidden variable models are inconsistent with quantum mechanical principles. Future experiments proved the above conjecture.

By assuming extra dimensions for space, and introducing strings as the quantum of matter and almost everything else, string theory is another attempt to explain quantum mechanical puzzles within the classical physics terms but in a more sophisticated way.

Many physical phenomena like electromagnetism are background independent. Standard model of particles has to be described within a background independent theory. It seems that building a theory within the dubious classical framework is a vain attempt and has to face a dead-end. Trying to explain the weird quantum mechanical phenomena with the current perception of the macro world is just an underestimation of the puzzles in hand. The fact is a can of worm is opened in front of our eyes which will drag us to unknown territories and new paradigms.

A paradigm shift is needed. Every route has to be explored. In the Brain lateralization theory chapter, we will examine the act of perception itself.  We may find some of the answers by exploring the perception proper.

Note; An excellent series of string theory videos in a layman term is produced by Brian Greene featuring Steven Weinberg and few other great physicists of our times. You can watch them at: Elegant Universe.
