The Fifth and Sixth Dimensions

[Deleter]

I would love to see a 2d persons idea of the 3rd dimension.

I think some of you have watched way too many science fiction movies. :roll:

Noone answered me in the other topics about time=4th dimension. So here we go again.
A dimension can be determined, correct? It goes in two directions, always, correct?
An objects location can be specified using the appropriate number of dimensions, correct?

For exampleOn a screen we use X, Y for coordinates, those are the dimensions there.
In real world we use X, Y, Z

Now, make me a proper coordinate for some random object in your room. This inludes time as a dimension set by you.
You wont succeed. It's impossible.. Why? Because time does not exist. It is simply a label we've set. A good proof of this is that time is not constant.
On a computer screen the coordinate 100, 100 is constant, it will stay 100, 100. Like any other dimension. However, if you set your clock to be exact, at your place. Then you move it, lets say.. 2000km to the west. Oh wow! You altered the 4th dimension! AMAZING! (You left your timezone)
So now we come to the fascinating topic of: What timezone is the correct 4th dimension? And how do we handle extra teresstrial objects such as other planets? What timezone do they use? Or is the 4th dimension changing? Thereby making it NOT a dimension? (Dimensions are always fixed, they're what determines an objects location)

Time is simply decay of atoms then. So you want to set the decay of atoms as a dimension? That's kind of... retarded.. Why not set the crashing of glas as a dimension? Oh, I know! The impact of meteors! One meteor = One step on the dimension.
Oh wait.. they only go one way.. just like.. time..
And as such they're not a dimension.

Zire, you're kind of stupid. Time certainly is a dimension, read my responses:

A dimension can be determined, correct? It goes in two directions, always, correct?
An objects location can be specified using the appropriate number of dimensions, correct?

For exampleOn a screen we use X, Y for coordinates, those are the dimensions there.
In real world we use X, Y, Z

Yes. So far you are correct.

Now, make me a proper coordinate for some random object in your room. This inludes time as a dimension set by you.
You wont succeed. It's impossible.. Why? Because time does not exist. It is simply a label we've set. A good proof of this is that time is not constant.

This is where you start to get really stupid:

On a computer screen the coordinate 100, 100 is constant, it will stay 100, 100. Like any other dimension. However, if you set your clock to be exact, at your place. Then you move it, lets say.. 2000km to the west. Oh wow! You altered the 4th dimension! AMAZING! (You left your timezone)

Timezones are just a simply fix for humans on Earth to synchronize their time of day with the right number as not to get confused when crossing or leaving the country. They have no real effect on time. At the exact time that it is 8 pm in London, it will be 2 pm at my house. This does not mean that time has changed in any way! You said yourself that a dimension must continue to infinity in both directions. A dimension must also continue to infinity inbetween two points. This is true not only with our physical three dimensions but also in time. If you go down to the very molecular level, you can see that changes happen so fast that even if time seemed to have stopped you would see events happening there. This is because time is relative to the being who is perceiving it. Relatively, ants feel time going much faster than we do. And giant animals perceive it slower I will bet.

So you are sort of right: Moving a clock 2000km in one direction will alter the CONTENTS of at least two dimensions: one physical dimension and then also the dimension of time.

So now we come to the fascinating topic of: What timezone is the correct 4th dimension? And how do we handle extra teresstrial objects such as other planets? What timezone do they use? Or is the 4th dimension changing? Thereby making it NOT a dimension? (Dimensions are always fixed, they're what determines an objects location)

Time is fixed as any other dimension. Like I said before, the perception of time is relative but the boundaries of time itself are fixed.

Time is simply decay of atoms then. So you want to set the decay of atoms as a dimension? That's kind of... retarded.. Why not set the crashing of glas as a dimension? Oh, I know! The impact of meteors! One meteor = One step on the dimension.
Oh wait.. they only go one way.. just like.. time..
And as such they're not a dimension.

This paragraph is completely and utterly stupid, and I wonder how you ever survived the first grade of elementary school, without being killed by your teacher on the principle of "someone that stupid just CAN'T live!"

was thinking that about someone else in this thread... :roll:

Fascinating. I look forward to your reply.

Read some of Stephen Hawking's stuff some time. Physicists believe there are 11 dimensions, but it takes a genius like Hawking to explain them.

The line between genious and insanity is pretty thin, I'm not too sure which side Hawking is on

TIme can be a dimension and is treated as one in many subsets of science, notably Einstien's general realitivity theory. Time is not, however a spatial dimension. The spatial dimensions (x, y and z) are all at right angles to one another, allow planes to be formed between them and physical movement can be expressed as a product of movement in the three dimensions. Time does not fit these properties, so even when it is treated as a dimension, it is not treated in the same way as the spatial dimensions.

You (seph) assume that because the space is described by three dimensions that there must also be three dimensions to describe time, however there is no evidence for this at all. We can use a six dimensional system to describe a position and orientation in space (x, y, z, yaw, pitch, roll), so do you also assume that you need an additional three dimensions in time to describe your orientation in it?

Having a second dimension to describe parallel universes doesn't work either. An object can only have a single location in the spatial dimensions, so similarly an event can only have a single location in your time dimensions (ie one value of U and T). Therefore an event can only occur in one parallel universe for an given value of T, which is fairly pointless.

There are as many dimensions as you can perceive.
