Recognizing that there are many outstanding questions concerning the fundamental nature of Time a model is described herein which it is hoped will provide some of the answers. The model aims to draw parallels between our common experience of time and the known laws of physics which govern the universe. The core argument is an identification of the future and past with potential energy and entropy respectively. This assertion relies on the belief that time can only be measured by change in the universe and change is effected by motion in the present. The present is, therefore, represented by kinetic energy, the energy of motion, and time is a measurement of the rate of transformation from potential energy (the future), to entropy (the past). In this way the physical nature of the future and the past are revealed as integral parts of what is observed as the present. Each object is its own clock. Time is therefore relative to an object dependent in part on all measurable expenditure of...

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.

Throughout the ages, "time" was an essential question for physicists and even more at present. Nowadays, physicists are trying to unify Quantum Mechanics and Einstein GR theory, to get an overall theory, which would represent the whole universe, from infinitely small dimensions to infinitely large, and "time" is a major element for this unification. This question of the real nature of time is a headache for philosophers and a real nightmare for physicists. Even today, there is no clear answer to that question. A great number of physicists claims that time doesn't exist, but it seems to be only a belief without a demonstration of its non-existence. However, does "time" really exist? Why do we have the sensation of an "arrow of time", while the equations of physics are reversible with the variable "time"? I am showing in this paper why time is not a real entity.

What is Time? Does time really exist? Is time an illusion? Can time travel be possible? Are there any existence of past or future? Can we predict future accurately? These are the most fundamental quests in the world which always make the Mankind puzzled. According to Physics, Time is a sequence of events (or more correctly moments) containing past, present and future. But there are no satisfactory attempts to explore the unknown reality of time .This paper raises the question over the existence of time and strongly emphasizes on the existence of “Single Moment i.e. NOW”. “ A Single Moment i.e. ‘NOW’ is the still picture of the conscious state of the whole Universe including our own consciousness. This single moment or still picture is perpetually, automatically and repeatedly getting changed and turns into new conscious state of the Universe.” Only one single old moment or conscious state is getting modified and changed into new single moment or conscious state . Thus we can not get...

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.

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 philosophical hypotheses, rather than purely scientific ones. The conflict between quantum mechanics and (general) relativity is shown to be a consequence of retaining the Newtonian conception of time in the context of quantum mechanics. As a remedy for this conflict, an alternative definition of time -- earlier presented in Kitada 1994a and 1994b -- is reviewed with less mathematics and more emphasis on its philosophical aspects. Based on this revised understanding of time it is shown that quantum mechanics and general relativity are reconciled while preserving the current mathematical formulations of both theories.

Understanding the nature of time remains a key unsolved problem in science. Newton in the Principia asserted an absolute universal time that {\it `flows equably'}. Hamilton then proposed a mathematical unification of space and time within the framework of the quaternions that ultimately lead to the famous Minkowski formulation in 1908 using four-vectors. The Minkowski framework is found to provide a versatile formalism for describing the relationship between space and time in accordance with relativistic principles, but nevertheless fails to provide deeper insights into the physical origin of time and its properties. In this paper we begin with a recognition of the fundamental role played by three-dimensional space in physics that we model using the Clifford algebra multivector. From this geometrical foundation we are then able to identify a plausible origin for our concept of time. This geometrical perspective also allows us to make a key topological distinction between time an...
