Pre 900: From the Middle English now, nou & nu from the Old English nū (at the present time, at this moment, immediately), from the Proto-West Germanic nū, from the Proto-Germanic nu, from the primitive Indo-European nū (now) and cognate with the Old Norse nu, the Dutch nu, the German nun, the Old Frisian nu and the Gothic nū. It was the source also of the Sanskrit and Avestan nu, the Old Persian nuram, the Hittite nuwa, the Greek nu & nun, the Latin nunc, the Old Church Slavonic nyne, the Lithuanian nū and the Old Irish nu-. The original senses may have been akin to “newly, recently” and it was related to the root of new. Since Old English it has been often merely emphatic, without any temporal sense (as in the emphatic use of “now then”, though that phrase originally meant “at the present time”, and also (by the early thirteenth century) “at once” (in the early Middle English it often was written as one word). The familiar use as a noun (the present time) emerged in the late fourteenth century while the adjective meaning “up to date” is listed by etymologists as a “mid 1960s revival” on the basis the word was used as an adjective with the sense of “current” between the late fourteenth and early nineteenth centuries. The phrase “now and then” (occasionally; at one time and another) was in use by the mid 1400s, “now or never” having been in use since the early thirteenth century. “Now” is widely used in idiomatic forms and as a conjunction & interjection. Acronym Finder lists 26 NOW acronyms including National Organization for Women; Night of Worship; No Other Way; Nightmares on Wax; Never Open Wide; National Orchestra of Wales (UK); Negotiable Order of Withdrawal; New Opportunities for Women; No Opportunity Wasted; Nonhazardous Oilfield Waste; Northamptonshire Orchestral Winds; Network-grade Optical Wireless. Now is a noun, adjective & adverb, nowism, nowness & nowist are nouns; the noun plural is nows.

“Now” is one of the more widely used words in English and
is understood to mean “at the present time or moment (literally a point in
time)”. However, it’s often used in a
way which means something else: Were one to say “I’ll do it now”, in the narrow
technical sense that really means “I’ll do it in the near future”. Even common occurrences treated as happening “now”
(such as seeing or hearing something) are really experiences of past events.
Because light travels at a finite speed, it takes time for it to bounce
from something to one’s eye so visual perception is an exercise in
looking back to the past; even when
reading something on a screen or page one’s brain is processing something from
a nanosecond (about one billionth of a second) earlier. For most purposes an essential conveniece, “now” is but a convincing illusion and even though, in a special sense, everything in
the universe is happening at the same time (now), while that can be imagined, it's not something easily experienced because of the implications of relativity. None of this causes many problems in life but
among certain physicists and philosophers, there is a dispute about “now” and
there are essentially three factions: (1) that “now” happened only once in the
history of the known universe and cannot again exist until the universe ends, (2)
that only “now” can exist and (3) that “now” cannot ever exist. These positions do appear irreconcilable.
The notion that “now” can have happened only once in the history
of our universe is nuanced because even the concept of "universe" is contested. According to some cosmological theorists, variously there
may be many universes, some which used to exist, some exact duplicates of our own (even containing an identical Lindsay Lohan), some extant and some yet to be
created (or "emerge"; the speculations differ). An alternative view is "our universe" may now be in one of its many phases, each which will
start and end with a unique “now” and that's tied up with the nature of time, the
mechanism upon which “now” depends not merely for definition but also for existence. That faction deals with what is essentially
an intellectual exercise whereas the others operate where physics and
linguistics intersect. Within the community holding "now can never exist" there's a sub-faction arguing that to say “now” cannot exist is a
bit of a fudge in that it’s not that “now” never happens but only that it can
only every be described as a particular form of “imaginary time”; an address in
space-time in the past or future. The
purists however are absolutists and their proposition is part of the nature
of infinity, something which renders it impossible ever exactly to define “now”
because endlessly the decimal point can move so that “now” can only ever be
tended towards and never attained. If
pushed, all they will concede is that “now” can be approximated for purposes of
description but that’s not good enough: there is no now.
The “only now can exist” faction find tiresome the proposition that “the moment we identify something as happening now, already it has passed”, making the point that “now” is the constant state of existence and that a mechanism like time exists only a thing of administrative convenience. The “only now can exist” faction are most associated with the schools of presentism or phenomenology and argue only the present moment (now) is “real” and that any other fragment of time can only be described, the past existing only in memory and the future only as anticipation or imagination; “now” is the sole verifiable reality. They are interested especially in what they call “change & becoming”, making the point the very notion of change demands a “now”: events happen and things become in the present; without a “now”, change and causality are unintelligible. The debate between the factions hinges often on differing interpretations of time: whether fundamentally it is subjective or objective, continuous or discrete, dynamic or static. Linguistically and practically, “now” remains central to the human experience but whether it corresponds to an independent metaphysical reality remains a dispute that, pleasingly for those involved, can go on endlessly because there's unlikely ever to be a "right" answer. Pleasingly, most people "now" alive and most who have existed have dealt with the concept "now" and its companions (past & future) without being much troubled by the squabbles among philosophers or cosmologists.
Cosmologists, if so minded, can dwell less on the nature of “now” because they have the “Andromeda paradox”, one of the consequences of Albert Einstein’s (1879-1955) theory of special relativity. What the paradox does is illustrate the way “now” is relative and differs for observers moving at different speeds, the effect increasing as distances increase, such as when the point of reference is the Andromeda galaxy, some 2½ million light years distant from Earth. Under special relativity, what one observer sees and perceives as “now” on Andromeda will, by another, moving at a different relative speed, be perceived as occurring in the past or future. This can happen at any distance but, outside of computer simulations or laboratories, the effects of relative simultaneity are noticeable (even at relatively low speeds) only at distance. The way to conceptualize special relatively is to imagine everything in the universe happening "at the same time" and "work backwards" as distances between objects increase.
