Time......

clocks don't exist without time, being as time is a measurement of the length of "time" it takes the earth to rotate 360 degrees on its pivotal axis.
 
time is just a name for the rotation of our earth. clocks and hours and seconds and days and what not, are just measures of time.

you crazy thinking is just stupid...
 
umm....actually thats wrong clocks can easily exist without "time"....and time is not based upon earths orbit, because in the nineteenth and 20th centuries it was obvious that that is inconsistent. ......humans make up time, time does not dictate ANYTHING in the universe energy is always there, simply transfered
 
A clock is an instrument used to indicate, measure, keep, and co-ordinate time. The word clock is derived ultimately (via Dutch, Northern French, and Medieval Latin) from the Celtic words clagan and clocca meaning "bell". For horologists and other specialists the term clock continues to mean exclusively a device with a striking mechanism for announcing intervals of time acoustically, by ringing a bell, a set of chimes, or agong.[dubiousdiscuss] A silent instrument lacking such a mechanism has traditionally been known as a timepiece.[1] In general usage today a "clock" refers to any device for measuring and displaying the time. Watches and other timepieces that can be carried on one's person are often distinguished from clocks.[2]Clock at the Royal Observatory, GreenwichContents [hide]1 History1.1 Sundials and other devices1.2 Water clocks1.3 Early mechanical clocks1.3.1 A new mechanism1.3.2 Early astronomical clocks[/list]1.4 Later developments[/list]2 How clocks work2.1 Power source2.2 Oscillator2.2.1 Synchronized or slave clocks[/list]2.3 Controller2.4 Counter chain2.5 Indicator[/list]3 Types3.1 Time display methods3.1.1 Analog clocks3.1.2 Digital clocks3.1.3 Auditory clocks[/list][/list]4 Purposes4.1 Ideal clocks4.2 Navigation[/list]5 Seismology6 Specific types of clocks7 See also7.1 Newsgroup[/list]8 Notes9 References10 External links[/list][edit]HistoryReplica of an ancient Chineseincense clockThe clock is one of the oldest human inventions, meeting the need to consistently measure intervals of time shorter than the natural units, the day, thelunar month, and the year.

A Brief History of Time is a popular science book written by Stephen Hawking and first published by the Bantam Dell Publishing Group in 1988.[1] It became a best-seller and has sold more than 9 million copies. It was also on the London Sunday Times best-seller list for more than four years.[2]There is also a documentary by the same name, directed by Errol Morris and released in 1991. Unlike the book, the documentary is primarily abiography of Stephen Hawking.Contents [hide]1 Book contents2 Editions3 Film4 References5 External links[/list][edit]Book contentsA Brief History of Time attempts to explain a range of subjects in cosmology, including the Big Bang, black holes, light cones and superstring theory, to the nonspecialist reader. Its main goal is to give an overview of the subject but, unusual for a popular science book, it also attempts to explain some complex mathematics. The author notes that an editor warned him that for every equation in the book the readership would be halved, hence it includes only a single equation: E = mc2. In addition to Hawking's abstinence from equations, the book also simplifies matters by means of illustrations throughout the text, depicting complex models and diagrams.[edit]Editions1988. Edition. This edition included an Introduction by Carl Sagan that tells the following story: Sagan was in London for a scientific conference in 1974, and between sessions he wandered into a different room, where a larger meeting was taking place. "I realized that I was watching an ancient ceremony: the investiture of new fellows into the Royal Society, one of the most ancient scholarly organizations on the planet. In the front row, a young man in a wheelchair was, very slowly, signing his name in a book that bore on its earliest pages the signature of Isaac Newton... Stephen Hawking was a legend even then." In his Introduction, Sagan goes on to add that Hawking is the "worthy successor" to Newton and P. A. M. Dirac, both former Lucasian Professors of Mathematics.[3][/list]The Introduction disappeared after the first edition. It was copyrighted by Sagan, rather than by Hawking or the publisher, and the publisher did not have the right to reprint it forever. Hawking wrote his own introduction for later editions.1996—Illustrated, updated and expanded edition. This hardcover edition contained full color illustrations and photographs to help further explain the text, as well as the addition of topics that were not included in the original book.[/list]1998—The Tenth Anniversary Edition—Is the same text as the one published in 1996, but was also released in paperback and has only a few diagrams included.[/list]September 2005 saw the release of A Briefer History of Time (a collaboration with Leonard Mlodinow), which is an abridged version of the original book. It was updated again to address new issues that have arisen due to further scientific development.
 
really? so the 23 hours, 59 minutes in everyday dont mean anything? it doesnt account for the 360 degrees that the earth rotates in that span of time? the 365.25 days in a year dont account for the time it takes the earth to fully orbit around the sun? clocks wouldnt exist without time, because a clock measure time, without time what does a clock measure......NOTHING!
 
^ what are you trying to say?....that just proves that time does not exist, simply because WE have to make something just to observe it....think about it
 
Ticking away the moments that make up a dull day

You fritter and waste the hours in an offhand way

Kicking around on a piece of ground in your home town

Waiting for someone or something to show you the way

Tired of lying in the sunshine

Staying home to watch the rain

And you are young and life is long

And there is time to kill today

And then one day you find

Ten years have got behind you

No one told you when to run

You missed the starting gun

And you run, and you run to catch up with the sun, but it's sinking

Racing around to come up behind you again

The sun is the same in a relative way, but you're older

Shorter of breath and one day closer to death

Every year is getting shorter

Never seem to find the time

Plans that either come to naught

Or half a page of scribbled lines

Hanging on in quiet desperation is the English way

The time is gone

The song is over

Thought I'd something more to say

Home, home again

I like to be here when I can

When I come home cold and tired

It's good to warm my bones beside the fire

Far away across the field

The tolling of the iron bell

Calls the faithful to their knees

To hear the softly spoken magic spells

oh yea all from memory, took me long to make it nice and need for you peeps to read

 
TIME! Is marching on.

And time.. is still marching on.

This day will soon be at an end and now it's even sooner.

And now it's even sooner.

And now it's even sooner.

This day will soon be at an end and now it's even sooner.

And now it's even sooner.

And now it's sooner still.

You're older than you've ever been.

And now you're even older.

And now you're even older.

And now you're even older.

You're older than you've ever been.

And now you're even older.

And now you're older still.

uhhh.....yeah calender time is measured by earths orbit, but seconds and hours are completely different...its like the amount of energy a sertain substance gives off in a sertain amount of time, thats exactly how rolex's work.......clocks DO NOT measure time, its not a measurment, its a controlled speed.....there is nothing to measure....its like buying a thermometer that always has the same temp, and saying that that measures temp
 
seconds and minutes are not different, if anything a calendar is different. it takes 23 hours 59 minutes for Washington D.C. to go 360 degrees around the earth pivoting axis, during this time it will pass noon and midnight, each are roughly 12 hours apart, thus your saying that time has nothing to do with the rotation of earth? the earth rotates at the same speed correct? and a hour in december is still as long as a hour in july correct? then how is time not a measurement? clocks dont measure time, the simply produce where we are on our rotation around earth, thus we have time zones, other wise 12 o'clock noon in new your would be 12 o'clock noon in japan, but in japan it would be dark out.......
 
ughhhh......yeah the earth rotates mkay, but does that really measure time? doesnt that seem completely random?....."oh time is gunna be decided based upon how long a planet rotates" ....like nah....yes the rotation of the earth is acurate, but why should THAT be the basis for time...all I'm saying is on a bigger scale time may or may not exist, either way it is completely useless. think about it, all the energy and matter that is in existence EVER will always be in "space" and since it will always be there, what does "time" have to do with anything, time doesnt happen, CHANGE happens, people just try to put a label on that
 
true, all i was saying is humans have come up with time as our way of telling where we are in the rotation, cause earth/matter/energy were always here, but time doesnt exist, didnt exist till we came along, we figure the amount of daylight to night that there was and the area of the sky the sun was in, and eventually came up with a means of measurement, time doesnt exist without humans, and clocks exist only to tell time.
 
Agreed, those are lyrics people should know. Not negative vibes, just a reprimand for ignorance of a great band. No hate either way.
I have to admit, the Floyd song was the first thing I thought of when I saw the thread title.
 
It is something that people dont understand, and when people dont understand something they make images to comfort themselves, just like the indians with the rain or sun god.
 
like you said time measures how long it takes the earth spin 360, which is useful when trying communicate and sceduale, so relative time is real because we made it up, but that doesnt mean theres absolute time.
 
Actually clocks are a way of recording simultaneous events. Also the earth doesnt match our 24 hour/day system. Think leap years. 24 hours is just easier. In physics time is an imaginary number which varies based on the speed of the observer. See lorentz transformations, Einstein etc. Now somebody with better knowledge of physics than me can feel free to show me up~
 
how is there not absolute time? how long does it take for the earth to rotate around the sun 360 degrees on its plant orbit? its not that we made up how long it takes earth to rotate around itself or the sun, its that we figured out how long these events take, and we figured out how the divide up into the seasons, you know for when the axis of the earth is at 1/4 rotation around the sun and the polar difference is effected, we figured how long it took to rotate 360degrees around ourselves, as i explained earlier, so time was always there, we just figured it out and how its measured, which we then used a clock to site and measure time.
 
well yea, leap years is how we have made up for the 23 hours and 59 or so minutes it takes to rotate 360 degrees, and after 4 years the extra minutes add up giving us the leap day? correct?
 
Sure it appears the earth takes 24 hours to rotate but the earth also appears flat when looked at on a small enough scale. Like scott22 said time is based on the observer.
 
if you think about time as a 4th dimension then really all clocks do is predict time based on an arbitrary starting point and scale. There's no way of really reading time because it can't be actually measured.
 
Time as a linear measurement exists.
flash_video_placeholder.png

 
Time is a component of the measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify the motions of objects. Time has been a major subject of religion, philosophy, and science, but defining it in a non-controversial manner applicable to all fields of study has consistently eluded the greatest scholars.
 
god i did NOT wanna leave something scientific, but here it is:

if time is, in fact, a dimension, then all points along this dimention exist at the same time. this means that time does not exist as a moving, progressing entity, which is how it is commonly percieved.

thats my take on it.
 
this thread is full of terrible.

steezyohio, you are entirely, completely, 100% wrong.

as is anyone else who says time doesn't exist, or that it's a product of human beings.

if anybody would like a real explanation, pm me. i'm not going to post in this thread because i'm tired, and it'll only get buried in stupid anyway.
 
some of you people need to read a goddamn book or something.

i suggest A Brief History Of Time by Stephen Hawking. the illustrated version in case the words don't make it through your skulls.
