It's Time to Define Time

Arxiv preprint gr-qc/9408027, 1994

Abstract: The notions of time in the theories of Newton and Einstein are reviewed so that certain of their assumptions are clarified. These assumptions will be seen as the causes of the incompatibility between the two different ways of understanding time, and seen to be ...

Various available definitions of Time are not able to define this term by not using references to terms directly related to Time. We find circular arguments and the use of entities that are undefined by themselves. Now we want to give a simple definition which will be understood from people and not only from specialized scientists. The question about what is time is studying under a technical and simple way. The different forms that such a variable can be found are pre-sented by using simple examples. Finally it is argued that Time is the one and only one non spatial variable that we need in order to describe the spatial evolution of any system under consideration.

TIME is presented in different areas of human activities such as philosophy, history, science. Several points of view upon 'time' were summarized and their evolutions in time were presented. Then 'time' is presented as in the general relativity and quantum theories from the beginning of the 20 th century. Further on other 20 th century emergent theories are presented, with ideas questioning the 'existence' or 'not-existence' of 'time'. In over 2500 years of debates over 'time', 'time' proves to be not understood yet.

It has been suggested by some authors that time has no physical existence, but it would be an illusion. The human being uses clocks for measuring the numerical sequential order of the duration of material changes, namely the motion which runs in space. We experience a run of changes in the frame of the linear psychological time "past-present-future", which has its basis in the neurological activity of the brain. We could link it with a concept of universe where there is neither physical past nor physical future. In this model of "time-free" space (in the physical sense) it exists only what we observe with our senses and measure with apparatuses.

The paper puts forward a conceptual framework in which the phenomenon of time can be presented and discussed in a proper way. We argue that change is ontologically and epistemologically a more basic phenomenon than time. Time is an abstract entity created by the human mind on the basis of the experience of change. Physical reality is a process of ceaseless becoming and vanishing; time is not a part of that process. Time is the abstract bank in relation to which we measure the intensity and amount of the flow (change) of physical reality. We must differentiate physical reality from abstract entities (language) by means of which we speak about this reality. It is necessary to differentiate a formal description (formulas) from its interpretation: a correct formal description can be interpreted in a logically inconsistent and factually wrong way. We argue that the discourse about the relativity of time joins (mixes) physical reality and language, and gives an inconsistent interpretation of correct formulas. Regarding the future of time, it has been said that physicists are divided between two options: (1) to pin down a "master time", as a measure of change of physical reality, and (2) to proclaim time "out of existence". We argue that both options must be adopted, because time is (1) a measure of change, created by the human mind, (2) and time is an abstract entity that does not exist in physical reality.

Importance of time in social laws

Time is the point where movement or system begins, to where it ends. Suppose there were no movements, there wouldn't be anything called ," time." Suppose the earth was not rotating or revolving, there wouldn't be time. Any system with miscellaneous movements have the beginning and the ending point be it a short or a long term. Time is all; science, culture, and economics provided there is movement, you can not account time where there is no movement. Take an example of agriculture production of maize, the system starts on the moment you put the seeds in the soil up to the final utility of the maize. There are various production and social movements but each with it's own time. There is no zero time. Scientists neglected the importance of time in social movements or social life. For example; it was a big error to omit " time " in the law of demand and supply then replaced by price which is a newly formed artificial media of exchange. Well as demand and supply existed before the invention of money in the era when man started to organise production.

In New Physics, the so-called hyperphysis, Time is a primordial basic concept used to help in the understanding of physical reality. On the other hand, Space plays a minor role secondary to Time, remaining an important notion nonetheless.

Different cultures around the world have independently discovered time in antiquity and developed calendars and clocks to measure this mysterious unknown. We say 'mysterious' because to this day no one has defined what 'time' is or means. Yet Mathematical Physics, particularly Special and General Relativity, are founded on time; neither can do without this strategic term. Time dilation is one of the three pillars of Special Relativity and the dimension of time is the fourth leg of General Relativity's ubiquitous space-time. What is it that theoreticians are stretching? What are they warping? Is time a dimension? Is it legal to replace height with time on a Cartesian chart and turn it into a Feynman diagram? And if time was born at the Big Bang, what is it that came to life? What does the babe look like? A closer analysis reveals that time is not a dimension. We discover that time cannot do without an observer. More fundamentally, we discover that unless we define this enigmatic word we will never understand what anyone who uses it is talking about.

Hilsa, a significant fish species in Bangladesh, undergoes migratory patterns between the sea and rivers. This study, conducted from 2018 to 2020 in four locations (Ramnewaz, Hazirhat, Janata Bazar, and Sakuchia) along the River Meghna in Monpura, aimed to assess the effectiveness and reevaluate a previously identified hilsa breeding ground. Variations in plankton composition and abundance were observed over multiple years and locations within the estuary. The presence of plankton in the hilsa’s gut during the spawning season emphasized its importance in the fish’s diet. The research focused on the length-frequency distribution and length-weight relationship of hilsa larvae (Jatka), studying their abundance and dispersion during high and low tides. Positive allometric growth in Jatka suggested the breeding area’s good health. Additionally, the study monitored the spent rate and maturity stages of hilsa, demonstrating the effectiveness of conservation initiatives. The existing management strategy, safeguarding breeding grounds and sanctuaries, contributed to a consistent increase in the hilsa population. The satisfactory parameters observed in the Monpura hilsa breeding ground indicated its stable and ongoing functionality. Consequently, the research findings are essential evidence and a valuable reference for future studies, policies, strategies, and the sustainable management of hilsa fishery resources.
