The First Law of Thermodynamics ***

The First Law of Thermodynamics claims that matter or its energy equivalent can neither be created nor destroyed under natural circumstances. One of the logical outcomes of this law is that there is no new matter or energy manifesting anywhere in the universe, nor is there any matter being annihilated. All matter and energy in the universe is therefore conserved. Consequently, this law is often referred to as the Law of Conservation of Mass and Energy. Although matter can neither be created nor destroyed, it can be converted from one state to another, i.e. from a liquid to a gas, liquid to solid, solid to gas. The overwhelming experience of experimental classical physics confirms this First Law to be a fact. As we shall see, this law has enormous implications regarding the nature of our universe.
