In this case, energy can only be exchanged between adjacent regions of space, and all observers agree as to the volumetric density of energy in any given space. There is also a global law of conservation of energy, stating that the total energy of the universe cannot change; this is a corollary of the local law, but not vice versa. [14] [15]
The word metaphor itself is a metaphor, coming from a Greek term meaning 'transference (of ownership)'. The user of a metaphor alters the reference of the word, "carrying" it from one semantic "realm" to another. The new meaning of the word might derive from an analogy between the two semantic realms, but also from other reasons such as the ...
