Buddy, your query holds weight in all of its concern, yet to monotonous these days to my knowledge. Since I have soothed such a query in past, I am withdrawn to another fabrication. Yet my previous answers weaved in a way can subside your curiosity as well. Consume a chunk of your time reading it. It may also answer your other questions: -\n\nThe concept holds itself in such an abstruse enigma, that centuries have failed to decipher its existence in a logical form. Scores of fiction writers have sculpted sci-fi books upon the behavior of time. We all have speculated over the so-called ‘Time Travel’ and have rummaged over the numerous possibilities that it may offer.\n\nFor the sweet sake of knowledge, once in a while, just sit down and think over the existence of time. When one questions ‘What is life?’ one is indirectly doubting his flow in time. Sometimes, time bears mercy upon you and hastens up, yet at other times, bestows upon you the curse of its viscous flow.\n\nYet, in reality what WE call time, is nothing but a theoretical fabrication that we, humans have crafted so as to better understand this “Fourth Dimension”. We assume we recognize time and its workings, yet mark my letters, we know absolutely N-O-T-H-I-N-G. We mortals imprint everything that we perceive in our brain, and then we analyze over it, yet never in its crude form. We find ourselves confined to the rigid boundaries of our senses. We bear to our knowledge the sphere of our vision and touch.\n\nThe notion bears itself in utmost simplicity. We can only conclude on matters we are able perceive in a correct mannerism. We do not bear such a sense organ nor are we able to implement over 4% of our brain, so as to perceive the concept of time in a proper ideology. Therefore we cannot chisel a concept concrete enough to bear the yoke of our questions.\n\nWe foolish mortals don’t even have the ability to measure time in its proper state. The state of time is always subjected to our memory, thoughts, personality, the circumstances, and innumerable other factors. You can’t even correspond two events in the same mannerism! Fragments from your memory are always erased, resulting to the unjustifiable way in which we perceive time.\n\nYet we can ALWAYS speculate! And we HAVE speculated! In such speculations, we have come to many ways to understand time. Scientists were entangled in similar doubts, yet they fashioned a theory that best satisfied the debatable world of ‘Philosophical Physics’. The theory states that time is completely relative to the individual who experiences it and furthermore a relationship exists between the three basic dimensions of space and time, leading to the birth of the space-time ideology. (I swear they stole the idea from me!)\n\nAnother speculation (Fasten your seatbelts for a Psycho Ride!). Suppose time is a fabric. (A complete supposition) A vast expanse of infinite non-molecular material. This fabric is existent yet not perceivable by our limited senses. If we are to possess a way to make a ‘cut’ in this fabric, we CAN gain access to two different periods in time. But then again, that is theoretical, and humanly impossible. \n\nSo far we have considered time to be a concept in whose relation we all exist. But in technical truth, time is relative to every individual! What we consider time is the manufacture of us mortals. What if time exists independently for everyone? When one perishes, he actually repeats his so called 'life'. Perhaps the period from the Big Bang to the collapse of the universe has repeated itself millions of times already! There is no telling, for there is no concrete platform, to which we can relate existence. We just have to relate everything to everything else!\n\nNow those are speculations. No one can state them correct or incorrect, for one does not bear a perception that great. Perhaps we are just the play-stuff of a superior colossal existence. Then again, what is existence?

Time is a thing invented by man.  Planets and such like don't care about time, they just keep on going forever which is a really long time.

Ya Time is just a measure of change... If there is change then you can say that there is time... No-time isn't a "theory" it's an idea, a thought game.

Yes, it is the same time here as there.  Time is an artificial construct; an illusion that we use to mark the progression of our stay on this planet.  Time doesn't truly exist, we exist and we use the various methods of measuring time (clocks, watches, egg timers, etc.) to keep track of how long we are in existence.

time is just a dimension. like length, width , and height,\nGod lives in a dimension beyond our scope,\nmuch like an ant maybe only realizes 2 dimensions,\neverything is like a plane to them, although it may be curved, they don't comprehend the curvature,\nas we don't comprehend the curvature of space and time.\nbefore and after is a concept that only applies to those who are constrained by 4 dimensions...\ni think God can put the beginning and end of space and time in one simple (package) concept, and \ni wonder what he will do for an encore?\ni don't know,\ni doubt he was playing solitaire

Well, time really doesn't exist. It's a human invention. We define time as what it is because our minds can't fully comprehend the fact that the universe is one big giant now. So nothing begins, or goes away, because everything happens at the same time. We choose to say it happens at different times, but it really happens in different places, on different planes of existence.

When talking about the universe, asking "why" something is the way it is usually has no absolute, 100% answer.\nThe best answer to your question is that the universe somehow began over 13.7-billion years ago and immediately began expanding. The expansion has gone on, steadily increasing the size of the cosmos until we observe its vastness today.\n\nGod should be spelled B-I-G B-A-N-G\nPBrax@netscape.com

it created its self, time travel was involved

Time is a relative perception. It is a man-made creation. We measure time from our perception (ie a year is one revolution around the Sun, a day is one rotation of the Earth, Weeks and months are based on Julian (Roman) and many other cultures' calendars from the past). Time is all relative. The most widely accepted reference point for time was 0 AD (Anno Domini, in the year of our Lord) Basically, based in Christian dogma.\n\nTime is something we cannot perceive in the physical world and is a very abstract concept. We say a light-year is the distance light travels in a year. That year is based upon our perception of time. However, if you took the length of Pluto's "year" or one revolution around the Sun, which is over 200 Earth years a light year would actually be a smaller distance (not by much, but it would make a difference).\n\nTo answer your other question. Air is required for combustion (namely the oxygen in the air). It is not required for explosion. The Sun is a constant nuclear fusion reaction created by the fusion of Hydrogen and Helium atoms. Also, most theories point to an anti-matter/matter reaction as to what created the Big Bang. The Big Bang is also a misnomer. Most likely, an imbalance of anti-matter and matter created a chain reaction resulting in an "explosion" and expansion of the singularity that began the Universe. However, that singularity wasn't inifinitely small. In relative size it was probably larger than several galaxies. However, an anti-matter/matter explosion creates pure energy. So, why is there still matter? Most likely, it was because the imbalance tilted to the matter side. Thus, leaving the matter that created the Universe. Matter is essentially highly condensed energy. Therefore, much of the energy created during the Big Bang went to both the expansion of the Universe and the creation of galaxies/stars/planets etc\n\nThe Big Bang also wasn't an "explosion" in the sense that you think of it. It is more widely considered a massive cosmolgical event and expansion caused by a massive chain reaction. Hence, why it is a misnomer.\n\nScientists measure "Time" from this point (the Big Bang), however, it is still unclear exactly how long ago it was, and our best estimates are still measured in Earth time (years.) And the galaxy is widely accepted to be about 15-20 billion years old.

It resulted from the big bang. Time and space and matter and energy all started then. What existed before and why it occurred is for the philosophers to ponder. I'm content with the fact that we don't know everything right now. We might someday though.

We invented the word "time" yes but that doesn't mean time wasn;t around before humanity. Time presumably began at the start of the big bang and its predicted it will end with the universe. \nReligous people believe in god who has always been around i.e.  *someone* who was around before time and will be around forever after time. \n \nHumanity discovered time, we didn't invent it.

there was no matter. our human mind cant comprehend the fact that God MADE matter AND TIME . God is not bound to time like we r. For to Him a thousand years in heaven is one day here.and a thousand years here is 1 day in heaven.doesnt make any sence unless u know the truth of God. not the public , deceptive view the world gives us.

Well, its pretty much as crimsonmoonvc said.\n\nUnlike the spatial dimensions of perception, time is not directly accessable by any sensory organ. We precieve time by the unfolding of the events around us.

Time now, is a universal thing.  It would be a pain to convert different time measurements.\n\nBack then when clocks and wristwatches weren't invented yet, different civilizations had different ways of telling time because of the lack of world-wide communication like we have now.  With today's technology it is easy to have a universal system for time.

I believe that true time is simply another dimension we just haven't figured out how to move in any but one direction. Time as in seconds, minutes, etc are nothing but a random measurement we have placed on that axis; more random than how we chose inches, feet, or meters for the other axis'.

It is a means of measurement of events that are taking place around us.   Think  of the days when people have relied on shadows produced by sun to be a measure of time.  They only understood that day and night repeat.  When the earth rotation of sun was understood, what we now term as 24 hrs a day came into being.  The past also was surmised to be at this time as Roman, mayan civilisation etc.,   hence wthout time the relative intervals of events cannot be placed and with new scientific inventions we are able to pin point happenings to part of seconds also.\nThe various calendars that have been made at different parts of the world also have taken events that have taken place as the basis or zero.   When scientific inventions result in exact no of rotations of earth that have taken place or earth got formed from the Sun, then that can be a basis and a new unit can be had for a fourth dimension.\nRamachandran V.
