QUIVER FOR TIME ARROWS
Facing any talk about the "mysterious and incomprehensible" nature of time, I want to say: "No magic, Ladies and Gentlemen!"
The universal measure of cosmic time (and space) is the speed of light. It is a constant in vacuum, 300,000 km per second. That is, one second is time light needs to cover 300,000 km.
Respectively, one minute is time for the photons to cover 60 times greater distance, namely 18,000,000 km. To express in kilometers one hour, one needs to multiply the above distance 60 times. Do you want to know what one year is? Here you are! Light needs one astronomical year to cover 9.5 trillion (9.5 x 10^12) km. A month is one twelfth of the same number.
14 billion years is a postulated age of Universe. It corresponds to 9.5 trillion km times 14 billions that is approximately 10^23 km - exactly the radius of visible Universe.
In other words,
TIME is the DISTANCE covered by light for that time.
It means: ANY TIME CAN BE EXPRESSED IN KILOMETERS.
Important corollary: If a variable is expressed in units of length, the variable is a vector. And any vector may not only have positive but also negative direction.
Believe it or not but existence of negative time is still disputed!
How come that we have lost the negative time?
Wherever the observer is located, he can see only light captured by receptors of his eyes. Photons moving away from the observer are not available for observation. They can only be seen if they are reflected by another object and get back to the observer. (Use of assisting optical gadgets does not change the principle).
Thus a registered light is the light which is emitted or reflected, but it inevitably should reach the observer.
As any flash of light takes place before it is seen, movement of photons toward the observer is directed from past to future. This is a normal, positive flow of time.
And vice versa, movement of photons in an opposite direction - away from the observer- occurs back in time, from future to past.
This is a negative flow of time when every next position is actually in a more deep past, compared with the previous one.
From any point of Universe (so-called "cosmic event"), both directions are possible, toward the observer into the future (the direct light cone) or away from the observer, to the past (the reverse light cone).
Excluding a spot where the observer is placed, any movement from that point is always directed to past, i.e. away from him.
Movement backwards, away from the observer, no matter where it starts, always secures a negative time increment. With this, the value of the increment depends on the speed of various objects moving in a light flow potentially capable to reflect these photons and redirect them toward the observer.
If an object moves slower than light, sooner or later it will be caught up by the light wave. In this way the object itself becomes a source of the reflected light and appears in positive time.
All ordinary cosmic objects that even first were in the reverse light cone of any light burst later will be always registered by the observer in positive time although with some delay as secondary sources of light.
For example, when an astronaut notices time retardation or a space traveler becomes younger in the "twin paradox" moving away from Earth, they do always live in the customary to us positive time, despite of a certain negative increment.
Positive time is our world, our reality, our measurement, as all objects of the material (with positive mass) world, including the observer himself, move with sub-luminous speed.
An upper (and unattainable) speed limit for such objects is the speed of light.
Only photons (the visible part of electromagnetic irradiation) and all elementary particles with no mass ("energy-carrying" particles) in general, can reach the speed of light.
When a particle moves away from the observer with the speed of light, a negative time increment corresponds exactly the positive time elapsed from the starting point (beginning of counting). The resulting time for such an object is ZERO. The particle starts moving and reaches destination at the same moment. Its time stands still. It is so-to-speak "catches up with itself", doubles like in the double-slit experiment.
An object moving with the speed of light acquires the ability to be present in several places at the same time, i.e. it gains the quality of wave. Thus the difference between wave and particle is that wave can be present in many places synchronously.
Particle made of matter becomes quantum of energy. By the way, the ability of photons to exist in positive and negative time synchronously explains their property to be antiparticles for themselves.
Finally, when the object exceeds the speed of light, the negative gain of time becomes so big that the object"s time will reverse and become negative followed by reversed cause-and-effect relationships. The superluminous object "reaches its destination before it has started".
As superluminous objects cover any distance in space faster than photons, they are always ahead of the corresponding light wave even if they are heading towards the observer. This surplus of covered distance (in comparison with the distance covered by light) will be again directed away from the observer, also takes place in negative time. Thus, objects exceeding the speed of light are in negative time constantly, independent of the directionality of their movement. Having not been reached by light, they are not able to reflect it and remain invisible.
Negative time is an invisible realm, another measurement, an alternative reality for the subluminous observer.
And in this alternative reality, there might be hidden the "disappeared" antimatter.
It is known from the quantum mechanics that antiparticles exist in negative time. The characteristic spin points at their presence in the reverse, past light cone.
It is logical to assume that also on a cosmic scale, there exist clusters consisted of antimatter, invisible for us because they move with supraluminal speed in negative time.
Indirect indications of their existence make scientists speak of some mysterious "dark matter" and "black holes", "swallowing even light". To be exact, we rather have to talk about the objects not reflecting light.
If the existence of superluminous invisible objects in cosmos is possible, why do we need to speculate about something tentative?
We "have lost" quite real ANTIMATTER that is supposed to be not less in quantity than ordinary mass, as according to the law of indestructibility of matter, pairs of particles-antiparticles appeared and disappeared in the primordial Universe. If particles continue to exist, why we should expect different behavior from their counterparts?
It may be so that the quantity of antimatter is even greater than the quantity of the "ordinary" mass since the process of annihilation of positive mass unit (+1) would not only require an imaginary (tachyons) unit (i), but squared imaginary unit (i^2), which can, at a certain moment, give the required quantity (-1) of mass for annihilation with the positive one.
All contradictions in interpretation of classic theories and the quantum mechanics are simply due to the fact that an investigator is having difficulty interpreting macro processes in relation to those described for quantum objects because on a cosmic scale, the investigator/observer himself is positioned inside, but not outside the system.
The above considerations could help in solving many burning problems and contradictions in Physics, particularly, to comprehend the nature of Big Bang, which is nothing else than a regular annihilation of all matter of the Universe with its all antimatter.
This annihilation Bang is capable of providing gigantic energy to start restitution of two antipode realms as part of an infinite cycle of radiation-matter metamorphose.
The Universe - a unique and comprehensive Cosmic Perpetuum Mobile - operates in the same way, as the only known to the modern science eternal system, a pair of particle-antiparticle in vacuum, in compliance with the law of indestructibility of matter/energy.
