Time dimension doesnt exist

[Tim_Lou]

if time is a dimension, that means there are others worlds with the same thing but different time.

but acording to the quantum rules, things happen in a chance. which means when something happened again in the same condition, it wouldnt be the same. then the other world with different time would have different events, as time goes on, the world would be totally different. so, there is only 1 time for one world, if there were more, those worlds would be different worlds.

sorry about my english, im a chinese.

By the beginning sentence I am assuming you mean that right now there is this exact same history going on in a different dimension, but just on a differnet spot in the timeline identical to ours. This could happen. Things do happen to chance according to quantum mechanics, but if there are seperate dimensions for every time, then there are infinite timelines going, thus every possible change that could have happened, is happening, or ever will happen is contained in it's own, unique timeline someplace. Which we as humans cant really imagine, infinity is a pretty big number

time isn't a dimention... never did einstein or his supporters concluded that time can exist independently.( only independent variables qualify to be called as a dimention), i see many people here are not aware that time is calulated as a difference of change relative to light travelling inbetween the two events, ie taking a measure of distence covered by light in some human contsants ( like one earth revolution..which again in subtle terms is not a constant) . time is abstract concept , but then we cannot understand universe without time can we?, well time is something that makes understanding this universe more logical and explainable, we need no time to live, we need time to understand, we can really never need time but yes we need to identify everyposition of every object in this universe with some number relative to some constant to better identify its position later relative to our position , what better can we take other than our own revolution of earth, which we know verywell.. hence as someone stated "time travel" is some concept of undoing the changes,, am i right?? we need not worry about time to undo changes if we can ever undo, for once if we do, time isnt required for us to interpret this universe, hence in laymen language we are eternal..

if you are standing still in space, then all of your speed is in the time
dimension. Then you start moving, so you are taking some
of your speed to the space dimension from the time dimen-
sion. Therefore, if you move at light speed in space, then
your speed through time would become ABSOLUTELY ZERO,
meaning time would stop for you or would it stop for every one
ther would be no tellin becouse u would have to get back to the time dimension to tell
but then u would be no longer in the space dimension to be able to stop the time in
its dimention.
If you somehow got past
the speed of light in the space dimension, then you would be going in REVERSE in
the time dimension, meaning you could go back in time by
exceedind light speed, even though this is allmost completely
impossible.but whilst in the warp betweeen time dimension and
space dimenstion were are you and if it is possible to go back in time how do we
know if sum1 all ready has been back in time mebe thats what dayzchavoo is,
when the things in our time now have to be
altered uterly becouse someone has gone back in time and changed soemthing in our passt
which meens we would have to go into the space dimetion to be able to have our pasts
changed so does that meen nearly every1 in the world has been into space.
and what is we somehow moved slower then still in the space dimension is that possible?
would we be exeeding the time dimension and entering a new dimention in the future
or would the universe somehow collapse just coz sum geeza thought is would be good
to play with people past present and future, innfact wwould we even have a present
End lecture. So, what do u think?

my name is joe and ive just descovered summit new





im clever haha i sat ther for hours workin on that

Time IS a dimension. Just as X, Y, Z... (height, length, width)

Dimension - 1 a (1) : measure in one direction; specifically : one of three coordinates determining a position in space or four coordinates determining a position in space and time (2) : one of a group of properties whose number is necessary and sufficient to determine uniquely each element of a system of usually mathematical entities (WWWebster)

When we are discussing something, we describe the item/ action based on it's existence relative to other items/ actions. This requires a description of it's RELATIVE position in space/time.

never did einstein or his supporters concluded that time can exist independently.( only independent variables qualify to be called as a dimention),

Nor has "length" ever been shown to exist independantly. Nor height, nor width... So if your def was to be accepted, ALL dimensions would be shown to NOT be dimensions.

i see many people here are not aware that time is calulated as a difference of change relative to light travelling inbetween the two events,

As is length (height/ width). A length can not be measured without knowledge of it's relative time component. As an object's fixed length stretchs/ compresses based on it's speed relative to the source of measurement, one can not give a length meansurement without giving it's realtive time dimension. When a time dimension is not given, it is assumed as being the same as the measurement source's. That does not mean it does not play a factor.

Thought experiment time. Two people are standing "next to each other" relative to a line on say an X co-ordinate. Person B walks 10 feet foreward on the Y (perpendicular) axis. Person A now measures how far they have to walk to reach the same (X coordinate) line that B had marked as 10 feet. Yet person A has measured the distance as 20 ft. How could this be? Person B was on a train moving foreward at the time. The RELATIVE time dimension of each was different, resulting in a different Y dimension even with a given distance measurement length (feet). Thus the dimension of Y was affected by the dimension T(ime).

time is abstract concept

so are the other 3. They are all RELATIVE to each other and the observer.

we need to identify everyposition of every object in this universe with some number relative to some constant to better identify its position later relative to our position

Thus you prove that TIME is a dimension.

maybe there is a constent moment within which all things occur and within which the brain perceives occurance and its own reaction to occurance and therefore a sense of duration. this would not mean that time exists as anything but a manner in which to measure the shared sensation in an evolving perceptive brain. did the universe begin so many eons ago? many scientists (or measuring brains) believe that the universe has always been while many believe it had a beginning. like string theory none of this has been proven so none of it has more weight than the philosophical hope that spurns them on. time may exist or it may be only another way for the human brain to link its perception to the universal (and therefore god) and so feel at least somehow related to the divine whatever. one must take an impossible step back before judging such things (there is a fundamental flaw in the measuring stick using itself to measure that which seems to exist around it.

A strange claim. What is the fundamental flaw? Are you saying that you cannot measure the size of your house because you live in it?

[mother engine]

i was thinking more along the lines of a house measuring a forest. the flaw would be in questionable perspective: as one cannot see a forest through the trees the mind cannot see beyond its perceptive abilities (taking into account the use of enhancement tools like a microscope).
