Introduction

 -----------------

 

The subject of the " journey in the time " is maybe the most absurd subject of fiction, but certainly the most stimulating for neurones.

The end of the 19è century and the beginning of the 20è century establish(constitute) a bend in the history of the scientific and philosophic thought.

If the notion of time aroused the questioning of the biggest thinkers of the history, it is during this period that it took all its dimension. At first Darwin showed that the man and any alive shape were the fruit of an evolution. The physicist Hendrik Antoon Lorentz and the mathematician Henri Poincaré anticipated that time was a relative notion before Einstein demonstrates him(it) in a indubitable way. Breast und Zeit, Martin Heidegger's essential work, one of the most important philosophers of the 20è century, turns around the notion of time. All the Bergson's work abounds in penetrating observations on the duration. Finally, in the field of the fiction, H.G. Wells has the brilliant blow to imagine for the first time, in 1895 , the possibility of a movement in the time in will due to his(its,her) " Machine to investigate time ". Even though idea can seem extravagant, she(it) conditions(packages) most of the works of science fiction which are going to follow and which one does not count any more. Some consider it moreover as the first work of science fiction.

Of important aspect of a work, at Zénon, Aristote, saint - Augustine, Newton, time became the centre of contemporary works important as those of Hawking and Prigogine. At the beginning of century, the astrophysicien Eddington said with good reason that time is " supreme law of nature ". As for Wells, it(he) had very well understood(included) him(it) and had formulated in what is maybe the deepest analysis at the time: " A cube can have a real existence without lasting during a some time? Manifestly, any real body has to extend in four directions(managements). It(he) has to have Length, Width, Thickness and... Duration. But by a natural infirmity of the flesh, we tilt to neglect this fact. There are really four dimensions: three that we call the three plans of the Space, and a fourth: Time. One tends however to establish an artificial distinction between first three dimensions and last one, because it turns out that we become aware of what surrounds us that by intermittence, whereas time passes by, of past towards the future, since the beginning till the end of our life ".

There is of what to stay without voice(vote) in front of an expression so clear of an essential education of the Relativity ten years before Einstein to conceive her(it). Besides the question to know if Wells had knowledge of Lorentz and Poincaré's works, which established(constituted) a beautiful draft of Einstein's works, an interesting question would consist in wondering if Einstein, Bergson or still Heidegger read Wells's book, and in which measure he influenced them. Let us note that this quotation can establish(constitute) a critical answer to the philosophy which sub-aims the famous work of Edwin Abbott Abbott, " Flatland ", extension of the Platonic idealism, and which does not consider that time is a characteristic appropriate(clean) for the world in three dimensions, because it shows itself in universes of lower dimensions.

 

 Prologue

--------

The prison of time

 ------------------

At first, a report.

We are any prisoners. Prisoners of the present, prisoners of time. We are the passengers of an infinitely long train which always spins any right, which can not move back.

A train which turns darker(charges) towards a disaster: the temporal collision.

Journey in the time seems to be the only way of us go out of it. It is what is convinced of the group Kronos. The group Kronos collects scholars and researchers of any disciplines. They envisage all the possibilities of making the SCOOP, the machine to travel in the time.

The solution of this problem is a question of survival. Let us put ourselves in the skin of an enquèteur which tries to discover and to collect essential data concerning the notion of time. She(it) concerns us all and touches all the domains of knowledge: psychology, mathematics, physical appearance(physics), history, biology, philosophy, literature... We have to thread the combinations(overalls) of the engineer, the artist, the scholar, the strategist, the thinker but always going away in the main thing.

 

 

  LEFT I

--------

The beginning of our enquète is going to consist in making the inventory of fixtures of searches on the notion of time.

 

Psychology of time

 --------------------

Psychology is a recent discipline. Before the creation, it is in the works of fiction that one doubtless finds testimonies most parlants on the feeling and the sensations of drainage of time. " In search of time lost " of Marcel Proust is maybe the most significant work, but " The magic mountain " of Thomas Mann, " The desert of Tartares " of Dino Buzatti and so many other works of the history of the world literature are not in rest: Shakespeare, Ronsard, Lamartine, Rousseau... Proust emits(utters) the interesting idea that there are temporal Illusions in the same way as optical illusions.

One can not ignore neither Bergson and Heidegger, even though, rather paradoxically, Bergson claiming of the psychology and Heidegger making philosopher's work, interest granted(tuned) to the psychology seems more present at the second than at the first, which becomes attached to a critical analysis of the knowledge and to a fundamental reflection on the nature of time, whereas Heidegger becomes attached rather to the way the man of which perceives time.

The psychologist Jacques Montangéro determined five characteristics establishing(constituting) the fundamental lines(features) of the notion of time: two main aspects:

 

Temporal hereditary order, that is the order of events or moments considered as discreet units and

Duration;

 

Three qualities, which differentiate order and interval temporal, of the order and the interval numeric(digital) and spatial:

 

The irreversibility which determines the fixed character of order - front can not become later in the same reference system-, and the unidirectionalité,

 

The alliance of linear and cyclic progress (spiral or wheel which turns: dialectic of the durability and the change) and the temporal horizon: past, present, future; at the beginning, environment(middle), at the end.

 

Montangéro considers simultaneity as a succession nobody, quite as Piaget, who associates besides succession in ordinal and duration to cardinal, is digital and analogical, order and interval.

One can move closer to these characteristics of the objective modalities of time established by the philosopher Kant. Kant determined clearly the essential aspects of time:

 

 * Succession: before / after

 * Duration: since / jusqu in

* Simultaneity: during, at the same time

 

Two events can succeed one another or take place at the same time. They have each a duration, they do without such at such moment. To decide on their simultaneity or on their succession, it is necessary to consider their origin. But previous history which succeed one another do not prevent that a part of the duration of each of events coincides. It is here that one realizes the wealth of duration. The determination of the simultaneity and the succession of two events requires(demands) to consider "moments" of each of these events, the two moments of each of their previous history. But the coincidence of two events can be determined in reference to their durability, to their duration.

Duration is the extension of moment.

But if he speaks about "objective" modalities, Kant asserts besides that time is pure shape, a priori , of the internal sense(direction), that is the sensibility: a sensitive intuition; it(he) makes it so a subjective notion.

As for the psychologist Paul Fraisse, it(he) established three laws:

1) The more an activity is split, the more it appears to last for a long time

2) The more an activity is interesting, the more it seems brief.

3) The time of a wait(expectation) is always too long.

It is enough, to illustrate these laws, to think of our perception of time at the dentist, the court, in concert, during the practice of our favourite sport, the school...

Einstein said: " Sit down one hour near a beautiful girl, it passes as one minute. Sit down one minute on an ardent heater, and it passes as one hour. It is it relativity ".

The relativity of time can be careful another way, according to the perspectives of the length and the short term. A period of boredom or idleness seems to continue, while time dedicated to a passion seems always too short. But when one thinks again about these active periods with enough recession(drop), the period of idleness is empty and does not take a place in the time, whereas period dedicated to the passion takes an important place in the time: she(it) lasts.

 

 Physiologie of time

 --------------------

These observations lead(drive) us to another testimony of the relativity of time. One can remain all its existence indifferent to the question of time and of its paradoxes, but it seems that nobody can refrain from having this unpleasant feeling which time crosses(spends) more and more fast, too fast, as one ages.

 

 Proportions

 -----------

We judge this acceleration of the drainage of time according to our sensations and our impressions(printings).

One could at first think that the same lapse of time takes a different value according to its direct report with the age.

For a, 5 year old child 1 year represent 1 / 5è of the life.

For a 30 year old man, the same period represents only 1 / 30è its life.

And for a 80 year old person, 1 / 80è of the life.

But if one respects these proportions, it would mean that the year of the 30 year old man should have to seem to him(her) 6 times as short as that of the 5 year old child, and that of the 80 year old person, 16 times as short as that of the child 5 year old and 2,6666 times as short as that of the 30 year old man. Absurd or to verify?

This explanation costs only if one returns reports(connections) between year and the age to more reasonable proportions. But question is then to know how to how determine them?

The biologist and the physicist P. Lecomte of Noüy brought a contribution important for the explanation of this paradox. It(he) established a constant of physiological activity of repair A which confirms developed proportions higher. It is the report between the size of a wound and its time of healing. Of Noüy showed that this report remains constant according to the age. Figures show that activity réparatrice tissues varies from 1 to 5 from 10 to 60 years. A wound which heals in 20 days at a 10 year old child will heal in 31 days in 20 years, in 41 days in 30 years, in 55 days in 40 years, in 78 days in 50 years and in 100 days in 60 years. At different ages, are needed different times to carry out the same work.

Now this individual time is measured with regard to the constant time of the revolution of the celestial bodies which serves of model in the time of our watches itself. This time is foreign to our vital activities. In fact, " the individual time of the alive things which are born and which die is more real and more significant for us than mathematical time conceived for us but foreign to our vital activities ", asserts sensibly this physicist.

Indeed, if one knocks down perspective and if one measures physical time by means of physiological time, one observes that physical time passes by more quickly in the end than at the beginning of the life, logarithmiquement, as that of the radioactive atoms, and more arithmetically. And one finds an explanation in the sensation of faster drainage of time with the age.

It is necessary to admit as a real fact that a sidereal year is shorter for an old man than for a child. She(it) represents for the old man a term more close than for the child. At the same time, it(he) will not be able to realize so many activities or to live as many sensations as the child. Besides, the mathematical curves which express proportions and the variations of the constant of physiological activity of repair A coincide on an important part of their length between 10 and 80 years. The hypothesis of proportions finds so a scientific confirmation in the observation of a concrete activity, the physiological activity of healing of a wound.

 

Biologic clock

 ----------------

Another way of explaining the sensation of acceleration of time with the age, is to get in touch her(it) with the slowing down of the biologic clock. Our brain works due to electric impulses which convey information.

Electric impulses have a frequency, that is certain number, rhythm of vibrations by unit of time: a speed. The waves of the day before, the attentiveness are waves "alpha". If rhythm, so the speed, so the frequency of waves alpha decreases, outside events will more fast seem to take place. Because the speed of assimilation of information slows down at the old person&. And always because of the fact that time is inversément proportional in the speed, time put by the old person to assimilate this information is longer than at a younger person. Trying(feeling) more and more difficulties following the rhythm of the daily life, the person feels(smells) its appropriate(clean) time to pass more and more fast by with the age. And as every individual compares, assimilates time outside his appropriate(clean) time, the old person has the feeling that this outside time passes more and more fast by. To understand(include) this phenomenon, it is not useless to think again about the acceleration of the appropriate(clean) time of Totus stayed on earth(ground) and in the slowing down of the appropriate(clean) time of Nihil which travels in the space at the speed of light; outside time, its not appropriate(clean) time, seems motionless for the traveler. As it(he) assimilates this time outside the appropriate(clean) time, it(he) has the feeling that the appropriate(clean) time is slow. But when it(he) finds Totus, Nihil realizes that outside time continued to pass by normally and that it is its appropriate(clean) time alone(only) which(who) slowed down. inversément, the old person has the impression(printing) which outside time more and more fast crosses(spends). She(it) assimilates this sensation in his(its,her) appropriate(clean) time. But if she(it) could have a point of comparison, she would notice that outside time passes by normally and that it is its appropriate(clean) time alone(only) which(who) accelerated.

 

 Relativity

 ---------

If one applies the principle of relativity, which will allow us to resolve scientific paradoxes, in this psychological time, time would more fast be supposed to be really the person who feels him(it) so. As frequency decreases with the estrangement in the case of a brilliant information, and gives a feeling slowing down of time, the decrease of the intellectual frequency with the age slows down the capacity of perception of stimuli at the old man.

 

 Maturity

-------

A third type of explanation of this phenomenon is based on the notion of "maturity". With the age acquires itself patience and sensation more fast to see spending time. A child does not want, does not know how to wait for the satisfaction of a need or a desire. It is impatient that she(it) comes true at once. Time will seem to him(her) all the more long as satisfaction is more distant or slow to come. Maturity learns us to master our implusions; the interval of time between the desire and its satisfaction seems less long and time appears so to pass more fast. Presented so, maturity could look like the resignation, the wait(expectation). But on the other hand, one grants(tunes) less attention in time, in the desire. So one acts more besides. And that to say some common sense which supports that old age falls again psychologically in childhood. From a certain age, time would begin again so to seem longer! And a paradox would come to mine(undermine) initial paradox.

 

 Memory(report)

------

Finally, it would seem that the sensation of acceleration of the ageing is bound(connected) to a decrease of the capacities of the memory, " if one considers that the subjective estimation of time is a function of the number of registered(recorded) information " (Vidal and Pacault, p. 222). The more the brain is capable of storing of information, the more time has to seem long.

It is likely that the resolution of this paradox passes by a mixture of various proposed solutions.

 

 Time, speed

 --------------

The invention of the cinema allowed to make an important discovery in the field of the perception of time. One realized so as for a human being, the speed of drainage of the reality is about 0,04s, is 25 images by second.

But it is the train of slug(shirt) compared with the movement of the particles of our body, which would make in a speed of 40000 km by hour, is 11,111 km by second. If one slows down at most this speed, 1m by second or 10-33cm at infinitely long time, the appropriate(clean) time of the particle is slowed down of so much because body will evolve at the speed of 1m by second or of 10-33cm at infinitely long time.
