4th dimenison isn't time.

[Parrot of doom]

Its quite simple.

All objects in this universe travel at the speed of light. They can neither go slower, or faster. In all 4 dimensions, their velocity must be equal to the speed of light.

So stand still in 3-dimensional space, and your velocity through the 4th dimension (time) will be the speed of light. Start moving through 1 dimension at half the speed of light, and your velocity in the 4th dimension will be half the speed of light. This is why time is experienced at different 'speeds' to people who travel at different velocities.

To the OP, you're defining the '4th dimension' as some kind of space just like the other 3. Well perhaps your definition is incorrect.

The fourth dimention could perhaps be explained as the "time" between two instances of "the cube"?

There's some crazy General Relativity theorists who can visualise in 4 dimensions. Fear them!

Nature doesn't have a numbered list of dimensions.

So don't number it? It's just a list. Nature can have lists. Things can be very straightforward, whether you have numbers or not. I could list the elements. I could number them just as easily as I could number the dimensions. They are very definite and seperate from eachother.

I thought we were discussing numbered lists, and how time is intrisically not the 4th dimension... hence the topic title?
People label it the 4th dimension when they do mechanics or relativity, etc.

It's just a label.
Actually in Physics, dimensional analysis allocates one dimension to space, one to time, one to temperature, etc, giving 7 dimensions.

Well, all the elements are actually different. Dimentionality is different. Dimentionality is a property of a space. A 4d space is 4 dimentional, what those dimentions are 4 arbitrarily chosen linearly independent unit vectors. Orthogonality can be important too.

So think of a 3d space. There's no arrows in the space saying which way is up, that's just a convention. You can rotate it and it's still the same 3d space, just from a different point of view.

Anyways, my point is that, no, there's no list of dimentions like there is of elements. There's a number of dimentions, what those dimentions are is can be chosen.

Tell me, if they are very definite and seperate from each other, which one is height, which one is width, and which one is depth?

Of course the 4th dimension isn't time........it's SEX.

Step one: Think of several topics concerning science or math.

Step two: Refine those ideas down to only include ones that could be easily debated because: 1.) It goes against most peoples' train of thought; 2.) Seems highly unlikely.

Step three: Create a thread stating selected math or science topic with shady sources.

Step four: Sit back and laugh.

Anyone here read Slaughterhouse Five by Kurt Vonnegut? We should just ask the Tramaflagorians...

Yes, the best way to get someone Qonfused. Happy 4000 btw.

No, it's not. It's another meaningless debate where people argue semantics rather than the actual topic they like to think they're talking about, as we've seen many times before in threads started by this pretentious little man who thinks he's an amazing intellect, to the bemusement of everyone else. It always goes the same way when he starts a thread with some supposedly insightful proposition/question. Hence my 'spam' response. So you shut up, please.

Aw look at the little baby

Anyway, so is time a dimension, or is it something that actually "exists"?

EDIT: God, it's too late, this whole thread has gone to the spammanoids.

THIS is why i'm starting to hate HL2.net

You forgot the part where I include an inflammatory line in my original thread belittling anyone who disagrees.

Sorry, I take it back, you clearly are a superb intellect.
