Time travel?

Time travel?

Where we cannot go with our physical body, we can get there with thought. In a hypothetical time machine equipped with a highly evolved technology capable of disconnecting the human mind from the 1-dimensional reality (in which it finds itself, united with the physical body, interacting with the surrounding environment) and projecting it into a other N-dimensional reality, that is in a different space-time dimension (for example in 2000 BC or 2300 AD)[1], the body of a hypothetical time traveler would find himself immobile on a comfortable “brain-wringing” model bed, while his mind (in a very remote terrestrial reality in the past or in a very distant future), associated with a body ” virtual “which obviously would seem completely real to him, could observe every event that in that specific time interval came to life, but never in any way could interact with them. “He”, in whatever N-dimensional reality he was in, would always remain a passive spectator, a ghost able to cross the walls without any effort, but with a heart that beats and therefore sensitive to any change in the state of his bio-condition. dynamic. What would not make him sink into the bowels of the Earth, would only be his … I believe, one’s willpower; that is that energy that, if used in other words, could even allow it to move … flying. Traveling through time, for this individual, would therefore be like having a daydream.

Each time interval is to be included (as a well-defined point) in a given oscillation of the curvature of the space and to each degree of oscillation, a specific model of space properly called N-dimensional must therefore be associated. This oscillation of the curvature of space could in any case be cyclical, and its duration could vary from a few minutes (which is not very credible) to a few millennia on Earth (which is a little more credible). The more or less reliable evaluation of the duration of the latter could be obtained indirectly if the frequency and intensity of gravitational waves could be measured.

If the oscillation of the curvature of space were truly cyclical, it would not be difficult at all to imagine patterns of space that would repeat themselves over time. To give an example: if in 1492 AD there had been a model of X-dimensional space on Earth, it could correspond exactly to its twin X1-dimensional of 2200 AD

. What other fundamental factor must therefore be taken into account in the construction of a hypothetical time machine (in addition to the measurement parameters concerning the oscillation of the curvature of the space), so that a possible traveler can safely decide to move in 2200 AD, without having to unwittingly find himself, after pressing a button, in 1492 AD? Simple, of the expansion of the Universe.

Up to now we have considered only the possibility, for human thought, of traveling in time; without obviously being able to prove that it really exists. Admitting this, despite the fact that this possibility reflects a certain level of probability inherent in the nature of time travel (from a rational-intuitive point of view) and therefore, that it is to be considered entirely plausible, we could ask ourselves: how it would look, before the eyes of a hypothetical time traveler who finds himself virtually projected in a time interval very far from his N-dimensional reality (for example in 2500 BC or in 6500 AD, or approximately 4500 Earth years away from his time interval), reality physical-dynamic surrounding it? He would perhaps see the images (i.e. the events) of this reality, distorted and therefore … “unnatural” due to a large difference in the curvature of the space compared to that inherent in the time interval he left (from his mind, be clear), to move to the past or future ? Or would there be no such problem at all, since its virtual image would immediately adapt to any model of space in which it found itself? Appealing only to common sense, we could easily choose the second solution. since his virtual image would immediately adapt to any model of space in which he found himself? Appealing only to common sense, we could easily choose the second solution. since his virtual image would immediately adapt to any model of space in which he found himself? Appealing only to common sense, we could easily choose the second solution.

To finish off this short digression on time travel (foreseen by Einstein’s equations in the theory of Restricted Relativity and never seriously taken into consideration by any scientist … serious, due to the Paradox of the twins, the Paradox of the grandfather and many other “logical” paradoxes that they involve), I will now consider the possibility, for a human being (or for any different physical body, whether animated or not), that is, for a physical entity formed by atoms and molecules and therefore weightable , to travel through time. I state that it is absolutely not my intention to be able to corroborate this possibility and even less to minimize it; what I intend to do is only analyze the most relevant aspects and consequences from a physical point of view ”

Imagine two points in space (A and B, see next figure), among which there is a certain distance (C), in three distinct dimensional situations; that is, in three distinct space-time fabrics. To facilitate your understanding, I would suggest that you compare the distance C to the space-time fabric.


Apparently, reflecting in Euclidean terms, it would seem that the distance between A and B decreases parallel to the decrease in the curvature of the space-time fabric, or vice versa, well this is not absolutely true.

Imagine that the space-time fabric (C) represents a long metallic filament therefore made up of atoms and molecules. Measuring the distance between the points A and B, that is between its ends, in any model of N-dimensional space we found ourselves, the filament would always appear to us equal. This is due to the simple fact that not only the metal filament is influenced by the curvature of space-time, but also the observer. Where then is it necessary to research the physical differences inherent in the three (see figure) filament patterns? Or, going back to time travel, in the three individual models (if the same individual finds himself in three different models of space or space-time fabric)?

Would the three filaments-individuals show the same quantum behavior in all the different models (three) of space-time? Let’s find out:

A dilated space-time fabric, due to its own “strong” curvature, implies a considerable decrease in the absolute value of Time (| T |) and in parallel an important increase in the absolute value of space (| S |). This important characteristic of the space-time fabric is nothing more than a logical consequence of the mathematization of the concept of space-time, that is K (where K represents a constant, present in every point of the Universe). This hypothesis-consideration was advanced on the basis of the idea of ​​Prigogine on a Universal time (which originally belonged to Bergson); concept that he developed in mathematical terms in the book “Between Time and Eternity” with an analysis of the distribution systems of the average internal times of space-time.

It is clear that no physicist … sane, would never dare to question the fact that space and time are entirely relative to the system to which they belong; and therefore never ever would venture to speak of an absolute space and time. But as we have seen, thanks to Prigogine’s work, it is possible at least to accept the idea of ​​an Absolute Time.

Now, fully accepting this premise, that is, that the entire Universe is defined by a sort of Absolute Time, thanks to that simple game of symmetries that has always characterized every new principle in the scientific field, its counterpart must necessarily also exist … that is the Absolute Space!

If we take for certain the assumption that the fundamental structure of space-time remains constant in every point of the Universe, we must also take it for granted that space and time must necessarily be subject to a universal law of complementarity, apt to guarantee the invariability of the fundamental structure of spacetime … in any region of the Universe!

At this point it would be completely wrong to believe that I want to propose, in other guises, the famous Cosmological Constant of Einstein; the product of space and time (whether absolute or relative) defines a constant (K) that cannot be expressed in units of energy (Joules, electronVolt, calories …)!

Instead, what represents this constant, which I have defined with the symbol K, is nothing but the spectrum, the “soul” of each space-time structure; obviously expressed with a symbolic unit of measure.

A parenthesis:

It has been known for some time now that, using the same words as J. Magueijo: ” the problem of the Cosmological Constant is given by the fact that the energy of the vacuum is not” diluted “by the expansion of the Universe, to the contrary to what happens to matter and radiation. For this reason, the energy of the vacuum would quickly end up dominating the Universe, unless there is a way to brutally suppress it already in the early Universe “.

Magueijo, an internationally renowned physicist of Portuguese origin, even claims that the speed of light is not constant in the Universe; from this hypothesis-premise he elaborated a series of theories related to the concepts of Special and General Relativity (which together are called VSL; the acronym translates into varying speed of light) with which he would, as he himself claims: ” found a way to exorcise the Cosmological constant “.

There is only one way to restore the concept of Cosmological Constant, without it coming into conflict with the laws of Theory of Relativity, and is to understand this Constant as a symbolic entity, linked to the concept of energy from such subtle planes , which today’s man is not yet able to visualize and therefore to expose in mathematical form; only in this sense, it is possible to identify the constant K, with the Cosmological Constant.

The increase in the absolute value of space implies, in turn, a necessary atomic-molecular compression of the object in question capable of guaranteeing its energetic compactness. This is a necessary condition so that the atoms that make up the body in question do not tend to dissociate from each other (which happens instead, the tendency to atomic dissociation, more commonly called radioactivity, to all those bodies that are in a space that tends to contract and where the absolute value of Time tends to increase considerably). A radioactive body must therefore be understood as a complex form of energy, capable of causing space to contract!

It could therefore be hypothesized that a radioactive body that moves in space at very high speeds, emits fewer radioactive particles, compared to another (identical) object that is instead in a state of quiet. We have therefore come to this point to propose in a new guise, as the final condition of our initial N-dimensional space-time model, the so-called … Length contraction (foreseen in the General Relativity and “similar” to that of Lorentz for high speeds; this analogy is evident to us if we consider the space traveled by a body in linear motion, as dilated with respect to the space that circumscribes the same body in an inertial system).

Let’s now compare our assumptions with some foundations of General Relativity in order to make them a little more evident and therefore, in certain aspects of … validating them:

RG theory predicts that clocks are slower near a mass. [The absolute time value decreases considerably when space tends to expand, and vice versa. A strong curvature of the space implies a strong expansion of the same. Around a mass the space is very curved, it follows that clocks must go more slowly].

The theory of the RG foresees that in proximity of a mass, the graduated rods (lengths) shorten.

An interesting aspect of the physical reality in which our very nice time traveler could find himself, after a few millennia from his initial time interval (that is, from his own model of initial space), is that it could make him appear (before the eyes of the Father Eternal, the only observer not subject to space-time constraints), with a different “stature” for each different model of space-time. Which he obviously could never realize.

All these “logical” considerations and deductions on the nature of time travel, we can accept them only if we take for granted the initial assumption on the cyclical oscillation of the space-time curvature of the Universe; otherwise they would make no sense….At the end:

I am simply saying that the mass of a body could vary depending on the curvature of the space in which it is located. The mass of a body moving away from the Earth should therefore in principle decrease significantly. This decrease, however, due to its infinitely small entity, will certainly remain imponderable for many years for the human race. Inertial mass and gravitational mass may therefore not be the same, but since on Earth the variation of the Gravitational Constant is too small to be measurable, nobody has so far never been able to infer this possibility. because of its infinitely small entity, it will surely remain imponderable for many years for mankind. Inertial mass and gravitational mass may therefore not be the same, but since on Earth the variation of the Gravitational Constant is too small to be measurable, nobody has so far never been able to infer this possibility. because of its infinitely small entity, it will surely remain imponderable for many years for mankind. Inertial mass and gravitational mass may therefore not be the same, but since on Earth the variation of the Gravitational Constant is too small to be measurable, nobody has so far never been able to infer this possibility.

Ultimately, we could venture the hypothesis that the frequency of the standing waves that define the energy levels of the atoms that make up a certain body that moves away from the Earth, due to the decrease in the curvature of space and therefore a slight contraction of the same, tends to increase significantly. In this case, the body in question would tend to exhibit a certain (albeit minimal) radioactive behavior, which would lead to an inevitable and obviously imponderable decrease in its mass. From this hypothesis, another even more bizarre one follows:

The increase in the frequency of the standing waves would entail a proportional increase in the quantum interferences of the system under consideration. The speed of decoherence[2] of this system, due to its progressive removal from Earth, would therefore tend to decrease; this is because there would be, in such a system, many more quantum interferences to be eliminated. The body in question could therefore in this case exhibit a certain quantum-classical behavior.

Returning for the umpteenth and last time to our dearest time traveler (Mr. Jack-fly-A), we could even imagine that he, in certain space models in which he was unfortunately “projected”, assumes a quantum-classic behavior. Before the eyes of a possible troglodyte or an eminent scientist of 2600, he could therefore appear and disappear; exactly like the light of an intermittent bulb. Such hypotheses or considerations, could certainly remind someone of the salient parts of Charles Berlitz’s book: the Philadelphia experiment. What if we were invaded by “hordes of tourists from the future” on a daily basis, contrary to what Hawking claims, but we did not realize it simply because we are unable to see them?

[1]The idea of ​​a multi-dimensional space must not deceive us by letting us fly with the imagination to imagine … “things of the other world”. Time is one and only and like the space with which it is associated, and in every second that the hand of our clock shows, an infinite series of space-time dimensions is included. In this case, it is necessary to be able to distinguish multi-dimensional space as a purely abstract concept that falls exclusively in the field of mathematics, from the classic (real) four-dimensional (3D + T) divisible, thanks to the infinite values ​​of T (time), in a series also infinite of “models” of space-time, carelessly and perhaps equally improperly defined N-dimensional. There are some theories in the field of physics that aim to demonstrate the possible existence of multidimensional realities (ND + T) that are not exclusively of mathematical domain, but physical and therefore conceivable only in other universes equally absurd and very far from our every possible imagination; in any case, these theories must absolutely not be taken into consideration in this context.

[2]In a “measurement” model, what produces the reduction of the wave packet is the interaction of the system with what is around it (for example the “measuring device” itself). More generally, quantum objects are never completely isolated from what surrounds them, where “what surrounds them” means everything that interacts with the system (a device, air molecules, photons, etc.). ..). The multiple interactions between the quantum object and “its surroundings” cause a very rapid destruction of the system’s quantum interference. Interferences are a wave phenomenon, and characterize quantum behavior. The destruction of interferences, in turn, entails a suppression of the superpositions of states that characterize the quantum object; it therefore, having only some simple states, immediately assumes a classical behavior. In a macroscopic object (a cat for example), each of its atoms interacts with all the other atoms in the environment around it. All these interactions spontaneously cause a “hum” of quantum interference, which disappears almost instantly. That’s why quantum physics doesn’t apply to our scale: systems are never isolated. This phenomenon has been called “decoherence”, since it is the destruction of the coherence of quantum states that eliminates interference. The decoherence speed increases with the size of the system. A cat, for example, made up of about 10e27 particles, “decoheres” in 10e23 seconds. This explains why “dead-living” cats have never been seen, and finally why decoherence is so difficult to observe.

The disclosure of information (whether scientific or not) should have no price, and should also be carried out through all possible and imaginable information channels, and since for now (thanks to the Internet), within certain limits this is possible, I have the firm intention to actively contribute in this “daring enterprise”, worthy of any adept belonging to the “Sect of the Extinct Poets”. My hope, of course, is that this freedom will never be taken away from anyone.
