This is very hard to explain withought diagrams. A book by robert bryanton called the 'Tenth Dimension' is a very basic and easy to understand adaptation. Here is also a flash video which explains is wonderfully :D http://www.tenthdimension.com/flash2.php Hope this helps

Without going into details, I belielve it can be proved that movment (or, more generally, change) cannot be continuous, from point-to-point - that is, space and time are not infinitely divisible (for example Zenon's paradoxes are relevant here) but they are quantified - there are elementary units of time and space which are not divisible any further. Many quantum mechanic physicists would agree with this. Th idea is that the process of movement is more like the TV animation - it gives the impression of continuity but it is actually jumps from one static frame to another - no "continuity" at all. There are two consqeqncies of this conclusion (and it seems they were not explored by physicists). 1) At that elementary level the speed is unique. A moving particle can only move one elementary unit of space per one elementary unit of time (or else the indivisibility of the elementary unit of time or space is broken). I'd add though that in order for the speed of movement to be variable at "macroscopic" level it needs to have two components at the elementary level (an ordered component of movement which would be observable at macroscopic level and a disordered which would only have an effect at elementary or quantic level). 2) Time, at least as we know it, doesn't and can't exist. The classical concept of time without continuous movement/change is lost. Time can't pass while a moving particle is in an elementary unit of space (because in order for time to pass, you'd have to divide the elementary, indivisible unit of time into smaller intervals and the passing would be from one of these smaller intervals to the next one). That is, the particle arrives and leaves a unit of space at the same time, simultaneously. Also, there can't be any time (or no time can pass) "while" the particle jumps, while it is "in transit" between two elementary units. If time could pass during the transit, the jump the particle couldn't exist any more. Since the particle is no longer in the initial elemenatary unit of space and it's not yet in the next unit it means that during the jump the particle is nowhere, that is it's in non-existence. Since the particle arrives and leaves a unit of space simultaneously and doesn't "spend" time in it (no time passes while it's there) it means that a moving particle spends all it's time in transit, that is, in non-existence. Therefore in order to give existence back to the particle we would have to give up on the concept of time. All the jumps are simultaneous and the particle moves with infinite speed. Continuing with these conclusions I developed my own theory of the universe. Based on the two components of movement mentioned earlier I defined space as determined by the ordered component of movement (I called it vectorial space), classical time as determined by the disordereed component of movement and the new time as determined by the total movement (I called it scalar space). Except for speeds close to the speed of light the two times are aproximately equivalent. This new time in relation to the old concept of time gets dilated just as in Relativity. If we draw the movement on a graph with two coordinates - space and time, time being the old time and we measure time in seconds (which is just a convention, others have done it before) - then the total movement in "space-time" (the hypotenuse of the triangle in which the two catheti are the space traveled and the time traveled - that is the old time - that is the one perpendicular per space because that's the movement that doesn't affect the macroscopical movement in space), so, the total movement is the new time. Mathematically, if you establish the realation between the the "old time" cathetus and the hypotenuse, that is between the old and new time, you get the same gamma factor of dilation from relativity (only that time is measured in meters, if you make the conversion you get exactly the same equation). Now, the infinite speed in terms of old time is 1 in terms of new time. Speed measured in terms of old time would be the tangent (or cotangent, depending which angle you take in the triangle mentioned above) which can grow indefinitely to infinite while in terms of new time it is sinus (or cosinus, depending on which angle you take) which has maximum value of 1. The speed limit in relativity is unexpected. The fact that moving towards the light or away from it still yields the same measurement for the speed of light is unexpected. In my theory the speed of light limit makes perfect sense... it's just the inifinte speed. Entangled particles in quantum mechanics "communicate" with infinite speed, that is simultaneously. But still nothing can travel faster than the speed of light. Well, both of them can be true if one measures speed in terms of old time and the other in terms of new time. One more comment, if you look up the definition of space (that is, meter, in the international system of measurements) it makes reference to the speed of light and time. Now if you look up the definition ot time (that is, second) it makes reference to the speeed of light and to space. It's a vicious circle. They both reference the equation: speed = space/time in which the speed is given, is taken as constant adn we are left with two unknowns, consequently, an unsolvable equation. Still, we can use the concepts of space of time in spite of this problem. Why? I'd say it's because space and time have the same nature so that it's not a vicious circle definition anymore.

In my investigation into the nature of TIME and SPACE in Dimensions (third and fourth), I have discovered some interesting properties that you can investigate also for yourself. One being: TIME and SPACE are not "linear". What you will need to conduct your own experiment: (1) Sleep Program (2) An Alarm Clock (3) Pen and Paper OPTIONAL: STOP WATCH This chart will help arrange your findings: DATE: TIME BEGIN SLEEP: TIME ALARM IS SET: TIME YOU WAKE UP: HOW MUCH TIME SLEPT: CONDITION OF ALARM CLOCK WHEN YOU WAKE UP: ( ON OR OFF ) STOP WATCH COUNT: ( If you used one ) ANSWER TO SLEEP PROGRAM QUESTION: An example of SLEEP PROGRAMMING: Say OUT LOUD: "I WISH TO KNOW THE TRUTH: ARE WE ALONE IN THE UNIVERSE?" Then go to sleep, you get the truth in a dream tonight. NOTE: You can substitute this question with any question you have and get the answer tonight via sleep. TO BEGIN YOUR EXPERIMENT: 1. SLEEP PROGRAM 2. SET YOUR ALARM CLOCK FOR ONE HOUR INTO THE FUTURE. 3. GO TO SLEEP. Please take note of the following: (1) Write down the answer to your question (2) Is your alarm clock ON or OFF, when you awake? (3) How much time elapsed while asleep and did it match up with your alarm clock time, your begin sleep time, wake up time, AND stop watch count? Please reset your alarm clock for ONE HOUR into the future, when you awake and are ready to go back to sleep. Gather data when you wake up. Do this the whole night to the best of your ability. Carefully write down your experience. You can do this for several nights to get an average. Good Luck! Gabriel Agbasi, Physicist

Time is a man-made concept to me, and doesn't exist.

it is non-linear according to my knowledge feynman diagrams and the space-time curve postulated by mr. stephen hawking may provide an explanation and if u want a practical explanation: take a stop-watch and start it while dropping an egg,u cannot reverse the phenomenon but,certainly the time conceptually can be reversed............. i hope u get ur answer.

well, if you look at a picture, preferably a hubble telescope image, of a galaxy, you're basically looking at hundreds of thousands of light years all at once. in that sense time is just an illusion brought on by the limit of light speed????? past,present, future is pretty much the same thing, i guess thats what the hindus and buddhists believe.....probably didn't answer your question, though because i know i'm still confused.

Time is caused by the particle I discovered, the Graviton. All atoms have gravitons in orbit around them. Gravitons can have incredibly huge orbits and travel in excess of 10,000 times the speed of light. Gravitons create gravity & inertia by bumping into matter on their return orbits. As the source of time they are the controlling factor in the escapement in clocks, fall of sand in hour glasses, orbits of planets, rotation of planets, etc...Alfred Herman Schrader

Read "Slaughter House Five" by Kurt Vonnegut. Sure it's an anti war book, but it has time concepts in it. Very thought provoking time concepts. Like death isn't the end, just the end of that one moment and you can visit any point prior to that "death". (Not the best explanation but if you read it you'd understand.) (I'm rambling.) (I tend to.) (Time...wasted)

Time is stationary, anything beyond it is beyond reality.
