Minkowski space is named for the German mathematician Hermann Minkowski, who around 1907 realized that the theory of special relativity previously worked out by Einstein and Lorentz could be elegantly described using a four-dimensional spacetime, which combines the dimension of time with the three dimensions of space. (Wikipeadia - Minkowski space)
?The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.? ? Hermann Minkowski, 1908

It has been proven that every time a space shuttle goes through the atmosphere, the speed makes it jump in time 3.5 seconds. Therefor, time travel is possible.
It is almost like a bullet. If you go faster than a fired bullet, the bullet goes behind you. You pass it. You jump ahead of it. If we go slower than the bullet, the bullet will go by as we go nowhere. We are traveling as fast as the bullet, so we travel where ever the bullet goes.
The bullet it like that certain speed that controlls time, almost like that "certain speed" can "jump" into the dimension of time for a microsecond and come back. If we manage to go slower, we will go back in time. If we manage to go much faster, we can jump in time.
NOTE:
This is all just a *theory* that I saw a show on the Science channel one day when I was *really* sick.

yes time is contestable: it is 3:00 in london and 5:00 somewhere else and when traveling at the speed of light, time stands still.
but in the same way, when traveling at high speeds, length,width, and hight contract.
so by saying time is a matter of perspective, you really aren't proving it isn't a dimension
You missed the point..but in the same way, when traveling at high speeds, length,width, and hight contract.

How do you measure time?
What IS time..
Taking out our stupid modern human ways of time = 1hour etc..
You're left with: Time = The decay of atoms (radiation)
So, you take the decay of an object and set that as a dimension?
Then I declare that shattering a glass is equal to traveling along the 2873844th dimension parallel to the plate shattering dimension of 23488577.
Also, too bad you can only go one way, damn.. crappy dimension you have there.. that'd be like.. nothing really.. as a dimension has to be able to go both ways into infinity..
However, sci-fi is fun, but stupid.. and it's sad how it's getting absorbed into real science without any explanation or logical proof whatsoever (Stephen Hawking being one of the more loud sci-fi enthusiasts)
Science used to be about finding proof.. not accepting wild theories and create formulas that work around them..

As Einstein said, time is relative to the observer, so time has to exist as a dimensional extension of the three spatial dimensions (or has a high order dimension encapsulating the three spatial dimensions).
As you approach the speed of light, time seems to slow down for the traveler as observed from a point outside the traveling frame of reference. The same thing happens when you get close to a black hole. To the outside observer, the person close to the black hole appears to freeze in time (ignoring the fact that they would be ripped to shreds due to tidal forces).
Since space can be described in terms of quanta, and time is integral to space (hence the term space-time) time is probably a quanta value that has yet to be discovered (although it may never be discovered, if it exists as a higher order dimension). Just as the hypercube is a four-space extrusion into three-space, time may be an extrusion into three-dimensions from a 4+ dimensional space.
Btw, time-dilation has been proven emperically by experiments in the particle accelerators and by observations of heavy atronomical objects, so the effect is real.

How many meters wide is your room?
Now.. answer me accurately, what's the time?
Also the blackhole or speed of light argument wont hold as it's theories.. For all we know time could speed up when you travel the speed of light. It wouldnt be the first time scientists were 100% wrong.
Back in the day radioactive materials were considered to be the cure of all, and the best thing ever. They feed cattle with it to increase growth. Think about that the next time you throw around scientific theories that are unproven.

A one second, quantized recording of sound at 44100 samples per second can be thought of as a one dimensional object located in a space of (44100 * maxamplitude) dimensions, or as 44100 two dimensional objects, each located along a one dimensional space, or as one two dimensional object located no where.
Fractals can be viewed as mathematical constructs with non-integer dimensionality.
The relative simplicity of generating imagery that appears to have depth with 3 dimensional calculations tempts us to view the world in these terms, and this is a temptation that grows stronger when we observe that left of left is left of right, closer than close is closer than far, and above above is above below. At a human scale, the world appears Euclidian in three directions, but merely facing two mirrors on two plumbed walls of moderate distance from each other is enough to destroy the apparent orthogonal nature of up and down versus left and right. The first resort of those still infatuated with geometry to take into account the curvature of the earth, and posit the entire coordinate system of the three dimensional room as a transformation of a global coordinate system of 3 other idealized dimensions, but even before we more forward to account for the curvature of space and time, we have already destroyed the "up, left, forward" that inspired us in the first place, for in the global or universal coordinate systems, these directions that have meaning only relative to our perspective, have no meaning at all. Meanwhile the flux of experience has turned merely cerebral, and none of it has had much inpact on how we actually perceive our surroundings.
The irony here is that this 3 dimensional notion of space came to fruition when artist first began to develope the laws of perspective and thereby, for the first time in history, portray an object as it might be seen by an individual, and thus displaying a particular image rather than merely a symbol of a general predicate. Over time, however, culture has done what culture has always done. The three dimensional view of space has been developed into a universal view point, blotting out the aspect of individuality that inspire it.
So the question need not be "what would the fourth dimension look like?" Much more apt is the question, "How can I interpret the world with four dimensions?"

I knew I wasn't the only time that read "A Brief History of Time"
and no, time is NOT a UNIT. it is a dimension. we measure time like we measure width, depth, and height. But time is a direction in which objects exist
ie: time is measured in hours, minutes, millenia and distance in feet, inches and miles.
and another thing...
Anybody who says time doesn't exist is wrong. saying itme doesn't exist is saying that length doesn't exist. Yes, we create measurements of time but that doesn't mean time is nonexistent

I bet we'll get as many answers as users on the forum (assuming everyone reply)
It's just a popular sci-fi influenced wrong that the 4th dimension is time.
As time for one doesent exist.

Dimensions are just directions or, ways we measure distance.
For example, I want to meet my girfriend but where? I might say the 3 floor of the buliding at the corner of 3rd and main. For the sake of arguement, 3rd st measures x, main follows dimension y, and the 3rd floor would be an the z axis. So there thats the 3 spatial dimensions...
The dimension of time is representiong by saying we would meet at 3:00.
remember,
1) dimesnions extend in 2 directions
x - left and right
y - back and forth
z - up and down
Time - before and after
2) dimensions have no smallest increment. There is no smallest increment of length, nor is there a smallest measure of time
PS: There are actually 11 dimensions! Try and wrap yout head around that one...
PSS: Hypercube is a retarded movie.
