Dear Vladimir,
Thank you for your kind comment and interesting questions. There are several reasons for including the Big Bang hypothesis in my scenario. First of all it remains the basic hypothesis of the beginning of the Universe in modern cosmology in spite of all its disadvantages. Nevertheless the beginning of the Universe was not my main research goal. My task was to show how the field interpretation of thermodynamics and the new understanding of the thermodynamic entropy could supplement the main physical theories and help decrease the incompleteness of modern physics. As for the role of philosophy in physics I completely agree with Carlo that it is now underestimated. Philosophy is very important for understanding of physics. It can supplement and update the existing methods of cognition.
Kind regards,
Boris
