Nature of Entropy

Abstract
One of the most intriguing laws in modern physics must be the Boltzmann’s entropy principle. As it stated, entropy within an isolated subspace increases with time, but it does not tell us why it has to be changing naturally with time. Since any evolution of our universe has a profound connection on her subspaces, from which we see that; there is a connection of entropy changes within an isolated (passive) subspace. Based on the big bang creation of our universe we see that; entropy within an isolated subspace increases naturally with time, since every subspace is a temporal (t > 0) subspace. In other words every subspace has a price tag; an amount of energy ∆E and a section of time ∆t to create. Yet without an amount of information ∆I it is impossible to created. Although entropy can be traded with information, but it is the amount (e.g., in bits) but not the actual information that most physicists assumed. I have also shown that Shannon type communication is for reliable information transmission and it is not purposely to make the transmitted signal more ambiguous as quantum entanglement communication has proposed.
