Philj,
I can now resume what have been said up to now:
1) Energy can neither be created from nothing nor can it disappear from the universe (1st law of thermodynamics)
Or, as physicists would say: subatomic particles can neither be created from nothing nor can they disappear from the universe.
2) Entropy always increases with time (2nd law of thermodynamics).
Or, as physicists would say: disorder of subatomic particles within atoms increases with time.
I have come to the conclusion that the following are similar :
Energy field
Force field
Particle field
Magnetic field
Matter (Particle field held together by the strong force)
These are various ways of saying: subatomic particle motion with varying forces.
Philj:
What determines the motion of subatomic particles so that the 2nd law of thermodynamics is true?
<i>Notes:
Quantum field theory provides a theoretical framework for constructing quantum mechanical models of systems classically described by fields or of many-body systems (particle fields).
Statistical mechanics (or statistical thermodynamics) is the application of probability theory, which includes mathematical tools for dealing with large populations (energy fields), to the field of mechanics, which is concerned with the motion of particles or objects when subjected to a force.
Quantum decoherence:
Decoherence occurs when a system interacts with its environment in a thermodynamically irreversible way.
Density matrix:
It describes the statistical state of a quantum system.
Situations in which a density matrix is used : nonequilibrium time-evolution that starts out of a mixed equilibrium state; and entanglement between two subsystems, where each individual system must be described by a density matrix even though the complete system may be in a pure state; and in analysis of quantum decoherence.</i>
