in other words, is time totally unreal or does it apply to everything constant, even fractions and nano applications?

i think it is real, as things only happen in one direction (eggs break, but never unbreak)...however, time itself is infinite, in that any one point is as the next...from comparing ourselves to distant galaxies, we see that time is like a loaf of bread, and it's perception depends on the way you slice it. check out The Fabric of the Cosmos: Space, Time & the Texture of Reality by Brian Green(e). He explains it way better than i can

i have a best answer here, although many may not see it that way....imagine the universe without time....next imagine that it is an elephant....then imagine time as a razor thin membrane ....lets start at the tail of the elephant....time is the razor thin membrane moving across the cross section of the elephant..you start with a few points where the cross section encounters the hairs of the tail...then you move on through the skin, and meat and eventually the bone....as time moves ever forward....the current moment is the cross section of the elephant at the current time....starting at the tail... every current event is a cross section of the elephant at the given time....every cross section is slightly different than the one before, and the one after....the universe is like the elephant... a thing that already exists... time is a moving cross section that only shows a slice of that whole....looking back at history... you can determine alot about the universe... you can see the *** of the elephant behind you, and you can predict what the next cross section is likely to be....but the universe is not an elephant... and there is no way for us to determine the final outcome.....so we can only look at the past, and try to figure what the future will be... if you are fairly intelligent....you will be able to predict the possibilities for the next cross section fairly accurately....if you are a dumass... you will make some pretty nonsensical predictions for the future.... but time is like that... nobody really knows what will happen... but if you use the brain you were given, then you can predict the future with a degree of certainty

Time is an instance or single occasion for some event; and as such is an infinite stream of measuring evolution; a constant applying to everything even fractions and nanoapplications -- even moreso due to the precision and tight tolerances of nanotechnology.

Physical time is a physical reality. The physics trilogy gives an answer as to what it actually is. The trilogy is: E = mc2, m = E/c2, and c2 = E/m. Notice that in all of these equations that the singular value that is unchangeable is that of the "c2" one. This value is what all mass and energy is made up of. We are composed of physical time, that is why all events move from the present into the past at the same rate in all places. Were this not so, whatever did not move into the past at the rate of everything else would cease to exist in our universe.

The value of "c2" is that of a speed as well as an energy value. The speed is that of light, and its energy appears to be that of Plank's constant "h". The trilogy shows the limitation of physical time to be that of light in speed. It states that all that exists in our universe is physical "present time" and then it is immediately gone. There is no manner at all for mankind to ever interact with the past or future, because they do not exist. Everything of the past exists in the present - it has just changed form. Everything of the future exists in the present, it just hasn't been put together. http://360.yahoo.com/noddarc and http://timebones.blogspot.com may be of interest.

TIME is just a illusion for human application. there nothing called time. its just a human reference.... if it is real then so many human evolution at least some should have felt and passed the information how to control it,

Bacterial organisms be able to "cope" to their environment. so as that they strengthen resistance to antibiotics distinctly if the affected person did no longer take the full prescribed process the antiomicrobial medical care. there are numerous who self-medicate besides (in many situations underdose) , they do no longer take the final drug dose, length of medical care and genuine timing. those are aspects which bring about antimicrobial resistance of bacterial lines. regardless of of that, loads of religious human beings could declare that GOD is all understanding, so it skill that GOD is conscious that Methicillin Resistant Staph Aureus, and not common-to-kill Pseudomonas Species could emerge --and God helps it. yet ofcourse, they could deny that God has something to do with those micro organism springing up resistance to great spectrum antibiotics. Or the omniscient and all-powerful author designed those bacterial organisms to "strengthen resistance" to antibiotics? The micro organism's coping mechanisms can not be as we talk linked with Evolution, even yet it somewhat is a demonstration that bacterial organisms be able to evolve themselves, as a fashion to proceed to exist -- they have self retaining mechanisms too. it somewhat is greater of version. yet interior the top it somewhat is nonetheless a bacterium... that progressed resistance to antibiotics and it did no longer develop into yet another organism. Evolution demands an organism to develop into yet another organism. Ex. fish turns right into a frog - ape right into a individual. it somewhat isn't any longer the case of the antibiotic resistant micro organism.

There are two distinct views on the meaning of time. One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence. This is the realist view, to which Sir Isaac Newton [1] subscribed, in which time itself is something that can be measured.

A contrasting view is that time is part of the fundamental intellectual structure (together with space and number) within which we sequence events, quantify the duration of events and the intervals between them, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows", that objects "move through", or that is a "container" for events. This view is in the tradition of Gottfried Leibniz[2] and Immanuel Kant,[3][4] in which time, rather than being an objective thing to be measured, is part of the mental measuring system.

Many fields avoid the problem of defining time itself by using operational definitions that specify the units of measurement that quantify time. Regularly recurring events and objects with apparent periodic motion have long served as standards for units of time. Examples are the apparent motion of the sun across the sky, the phases of the moon, and the swing of a pendulum.

Time has long been a major subject of science, philosophy and art. The measurement of time has also occupied scientists and technologists, and was a prime motivation in astronomy. Time is also a matter of significant social importance, having economic value ("time is money") as well as personal value, due to an awareness of the limited time in each day and in human lifespans. This article looks at some of the main philosophical and scientific issues relating to time.

Many ancient philosophers wrote lengthy essays on time, believing it to be the essence around which life was based. A famous analogy was one that compares the time of life to the passing of sand through an hourglass. The sand at the top is the future, and, one tiny grain at a time, the future flows through the present into the past. The past ever expanding, the future ever decreasing, but the future grains being moulded into the past through the present. This was widely discussed in around the 3rd century CE. [citation needed]

The earliest recorded philosophy of time was expounded by Ptahhotep, who lived c.2650 -2600 BC said: "Do not lessen the time of following desire, for the wasting of time is an abomination to the spirit."

In the Old Testament book Ecclesiastes, traditionally thought to have been written by King Solomon (970-928 BC), time was regarded as a medium for the passage of predestined events.

"There is an appointed time for everything. And there is a time for every event under heaven— A time to give birth, and a time to die; A time to plant, and a time to uproot what is planted. A time to kill, and a time to heal; A time to tear down, and a time to build up. A time to weep, and a time to laugh; A time to mourn, and a time to dance. A time to throw stones, and a time to gather stones; A time to embrace, and a time to shun embracing. A time to search, and a time to give up as lost; A time to keep, and a time to throw away. A time to tear apart, and a time to sew together; A time to be silent, and a time to speak. A time to love, and a time to hate; A time for war, and a time for peace." (Ecclesiastes 3:1–8)

Around 500 BC Heraclitus, a fatalist, held that the passage of time and the future both lay beyond the possibility of human influence: "Everything flows and nothing abides; everything gives way and nothing stays fixed. You cannot step twice into the same river, for other waters and yet others, go flowing on. Time is a child, moving counters in a game; the royal power is a child's."


[edit] Time in philosophy
Newton believed time and space form a container for events, which is as real as the objects it contains.

"Absolute, true, and mathematical time, in and of itself and of its own nature, without reference to anything external, flows uniformly and by another name is called duration. Relative, apparent, and common time is any sensible and external measure (precise or imprecise) of duration by means of motion; such a measure - for example, an hour, a day, a month, a year - is commonly used instead of true time." -Principia [16]

In contrast to Newton's belief in absolute space, and closely related to Kantian time, Leibniz believed that time and space are a conceptual apparatus describing the interrelations between events. The differences between Leibniz's and Newton's interpretations came to a head in the famous Leibniz-Clark Correspondence. Leibniz thought of time as a fundamental part of an abstract conceptual framework, together with space and number, within which we sequence events, quantify their duration, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows," that objects "move through," or that is a "container" for events.

Immanuel Kant, in the Critique of Pure Reason, described time as an a priori intuition that allows us (together with the other a priori intuition, space) to comprehend sense experience. With Kant, neither space nor time are conceived as substances, but rather both are elements of a systematic mental framework necessarily structuring the experiences of any rational agent, or observing subject. Spatial measurements are used to quantify how far apart objects are, and temporal measurements are used to quantify how far apart events occur. Similarly, Schopenhauer stated in the preface to his On the Will in Nature that "Time is the condition of the possibility of succession."

In Existentialism, time is considered fundamental to the question of being, in particular by the philosopher Martin Heidegger. See Ontology.


[edit] Time as "unreal"
In 5th century BC Greece, Antiphon the Sophist, in a fragment preserved from his chief work Truth held that: "Time is not a reality (hupostasis), but a concept (noêma) or a measure (metron)." Similarly, Parmenides believed that time, motion, and change were illusions, leading to Zeno's paradoxes (Zeno was a follower of Parmenides).

Ralph Waldo Emerson considers time as presentness, where past and future are but our present projections (of our memory, hope, etc.). For Emerson, time needs a qualitative measurement rather than a quantitative one.[citation needed]

Writers such as J. M. E. McTaggart in his 1908 The Unreality of Time have argued that time is an illusion (see also The flow of time).

Psychology
Different people may judge identical lengths of time quite differently. Time can "fly"; that is, a long period of time can seem to go by very quickly. Likewise, time can seem to "drag," as in when one performs a boring task. The psychologist Jean Piaget called this form of time perception "lived time."

Time also appears to pass more quickly as one gets older. For example, a year for a five-year-old child is 20% of his entire life so far, however for a 50 year old adult a year is only 2% of his entire life so far; so with increasing age, each segment of time is a decreasing percentage of the person's total experience.

Altered states of consciousness are sometimes characterised by a different estimation of time. Some psychoactive substances--such as entheogens--may also dramatically alter a person's temporal judgement. When viewed under the influence of such substances as LSD, magic mushrooms and peyote, a clock may appear to be a strange reference point and a useless tool for measuring the passage of events as it does not correlate with the user's experience. At higher doses, time may appear to slow down, stop, speed up and even go backward when under the influence of these agents. A typical thought might be "I can't believe it's only 8 o'clock, but then again, what does 8 o'clock mean?" As the boundaries for experiencing time are removed, so is its relevance. Many users claim this unbounded timelessness feels like a glimpse into spiritual infinity. To imagine that one exists somewhere "outside" of time is one of the hallmark experiences of a psychedelic voyage. Marijuana may also distort the perception of time, although, to a lesser degree than psychedelics.

The practice of meditation, central to all Buddhist traditions, takes as its goal the reflection of the mind back upon itself, thus altering the subjective experience of time; the so called, 'entering the now', or 'the moment'.

In explaining his theory of relativity, Albert Einstein is often quoted as saying that although sitting next to a pretty girl for an hour feels like a minute, placing one's hand on a hot stove for a minute feels like an hour. This is intended to introduce the listener to the concept of the interval between two events being perceived differently by different observers.
