# Reversible time

*Reversible Time*…* Reversible or Irreversible?*

Classical physics says time is reversible because its laws hold true whether time flows forward or backward. Thermodynamics says time only flows forward, because were it to reverse, entropy of an isolated system could decrease which would violate the second law of thermodynamics.

So, time is reversible or irreversible? The answer, can not be deduced from either classical physics or thermodynamics because both are flawed in their understanding. *Reversible Time*

**Classical Systems are Timeless **

Classical physics only deals with deterministic systems whose past, present, and future are entirely in a single timeless equation. As a result, for such systems time does not exist except as spatial increments marking the various aspects of a static pattern frozen in eternity. Moving on one way or another on a static pattern does not change, and for this reason the laws of classical physics hold true regardless of whether the time variable is positive or negative. Because the time is not an intrinsic part of deterministic systems, classical physics has nothing valid to say about the nature of real-time. *Reversible Time*

**Thermodynamics Just A Suggestion **

Thermodynamics is a statistical science that calculates trends rather than individual events. This means it sweeps complex molecular motion under the rug and only makes observations about the resulting lump sum. It is important to remember that according to classical physics, molecular motion is deterministic, implying that thermodynamic systems must also be deterministic because they are only a collection of deterministic molecules. If the components of the system is time reversible, then so must the system itself.

So, why does thermodynamics demand a time change? Because due to the large complexity in keeping track of all deterministic molecule, it is forced to ignore this level of accuracy in the case of reversibility lived.

The illusion of time irreversibility in thermodynamics comes from two problems:

1) its inability to calculate system accuracy absolute, which prevents it from mathematically confirming time symmetry, and

2) that its laws are based on incomplete statistical observations and assumptions.

Time symmetry or reversibility requires that the laws system in question do not change when time is reversed. In classical physics, this is easy to check because the past and future of the system can be calculated with an accuracy of absolute. But thermodynamics cannot completely know the complete characteristics of a system due to its molecular details are too complex to take into account. So it can not even compare the forward and reverse systems to check for symmetry because they are too complex. On this point alone, thermodynamics, therefore, are inconclusive about the nature of time. *Reversible Time*

**Thermodynamics Makes Statistical Laws Apply to Individual Cases **

Go to statistical observations, it forces a match between limited laboratory observation and mathematics by fatally assuming that instead of collections of deterministic particles, things are made of perfect fluids. This is done as a matter of practicality smooth over the randomness of molecular motion, which unfortunately throws out its inherent deterministic and time reversible nature.

Assuming a perfect fluid like assuming that every family in America has just 1.3 children, to match the national statistics. While this is a neat mathematical device, when it gets taken too seriously any family’s demand to have two children is seen as impossible because it would “violate the statistical law.”

Likewise, when time is reversed and entropy decreases, as a result of the violation of the second law of thermodynamics should be no cause for alarm because the second law only on separate statistical trend, not an absolute, a pillar of physics as its supporters claim. It seems universal but only because of the mathematics of apparently, support it, but remember that the math in thermodynamics is built on the assumption that the systems are made of perfect fluids.

Although the systems of which science is restricted to observations than to show increasing entropy, this says nothing about the ignore system. What applies to elite does not need to be universal for the most part. In truth, a reduction of entropy contradict anything because it is not impossible – it’s just there is a probability lower than was the system of increase of entropy. Therefore, the mathematical and observational proof in thermodynamics is sufficient to claim that time is irreversible. *Reversible Time*

**Proper definition of Time Irreversibility **

So, how can we determine whether time is reversible or irreversible, being that classical physics and thermodynamics is now out of the debate? We see that thermodynamics is on the right track – stated another way, time seems irreversible because the future is more uncertain than the past. While the past can be clearly observed from watching what happened in the system, if the calculations are able to perfectly predict the future, as well as, the future seems murkier. So, the future seems always “make” which gives rise to all of the flow of time.

But this murkiness of the future but only because of incomplete information associated with the individual particles of a thermodynamic system. We had to know them in detail, in fact we could see that the future is as certain as that of the past and at that time in that case is reversible. The nearsightedness of an observer says nothing about the intrinsic fuzziness of the object observed; that science cannot determine the future state of a system does not mean the system itself is nondeterministic.

**Quantum Mechanics Proves Direction of Time **

It should now be clear that only nondeterministic systems are time irreversible. Time, can not be symmetrical in systems have a future that is not already contained in some tidy equation by connecting it with the past.

Do such systems exist? Yes, quantum processes are nondetermistic by nature. What state a wave function collapses into cannot be predicted mathematically. Quantum mechanics is a lot like thermodynamics in the sense that its laws deal with the statistical trends of random processes, but there is one crucial difference: the unpredictability of the quantum system comes not from the shallowness of the observer on perception, but on the compact nondeterministic nature of the system itself.

Then, how exactly does time arise? By consciousness sequentially choosing which aspects of quantum wave functions to be interpreted as a physical experience. Choice is nondeterministic because it did not, it would already be pre-determined, leaving no choice. Choice requires freewill, so the irreversibility of time ultimately stems from freewill to not be predictable or easily undoable.

Maybe this sounds like new age mumbo jumbo to you, but all this it is clear from the mathematics of quantum mechanics. There are no hidden variables in quantum theory, only those created on the spot by conscious selection. Nothing in quantum physics contradicts this idea. *Reversible Time*

**Consciousness and Quantum Phase **

The phase of a wave function is entirely “arbitrary” according to physics, and it is precisely this phase that creates huge consequences for how the time-dependent wave function evolves and interacts with other wave functions. In fact, the phase factor is not arbitrary, but deliberately chosen at some level of consciousness because of its being isolated from the deterministic (statistical) parts of quantum theory, the stage is left entirely to the option of choice. This shows how mind ultimately affects physical reality, not by violating its classical laws, but by working through nonlinear systems to amplify “arbitrary” quantum fluctuations into macroscopic effects.

Time dependent wave functions show how consciousness creates time. The only reason they appear to progress through the time that they consist of multiple stationary states (wave functions independent of time) whose various phases change to produce a “moving” wave function. But the steps are chosen by consciousness, and since it is the phase that give rise to the seeming time-dependence of a wave function, it should be beyond debate at this point that consciousness creates time.

In addition, when the wave function has “collapsed” (one disc the jukebox selected to be good), it cannot “uncollapse”. The collapse of the wave function is time reversible because of the mathematics it can not be calculated equally well on face and back. Only linear systems which are perfectly predictable at time reversible. So, once more, time is irreversible when, and only when it comes to quantum systems and there will be a choice.

**The Interface Between Quantum and Classical Systems**

How does all this fit with the systems of classical physics? Classical systems are only a set of deterministic effects, although conscious choice is the original nondeterministic cause.

The interval between deterministic events is known as linear time, which is illusion for the simple fact that the span between first and last effect is redundant and thus nonexistent except to the observer choosing to observe it as real. Deterministic systems appear to move only because our consciousness slides its observational focal point along the eternally static pattern of the system, not because the system itself is changing.

As an analogy, the songs on a CD do not change with time because they all exist simultaneously as data on a disc, and any illusion of time between beginning and end of a song arises solely from them being played as such. When a CD is played, it progresses at a default sequence, direction, and speed – but these can be changed if one chooses to skip tracks, increase the speed, or listen to it backwards, all without actually changing the CD itself.

True time does not span intervals of deterministic sequences, but rather intervals of freewill choice. If consciousness were to choose to view the static pattern backwards, sideways, or in jumps, then that is perfectly permissible. The term “irreversible” only means that there exists a tendency for time to progress in the direction that conscious choices are made.

Thus, reality progresses in piecewise deterministic jumps. This can be compared to how road trips consist of roads and intersections. What roads have been traveled determine which new roads are available at an intersection, but not which particular road will be chosen. Quantum physics equations show what roads are available, but consciousness ultimately decides which to follow.

And so it is with reality – the choices we make determine what choices are available, but not which ones we’ll end up making. Thus, classical and quantum processes interact to give rise to the rich dynamic fractal we call life. *Reversible Time*, *Time symmetry *
