## Recommended Posts

hello, kids,

what is a hyper cube

and i understand wat the first four dimensions are but wat are any other dimensions that can be talked about. like i can comprehend time and space but wat else could ther be.

thanks men of earth

a hypercube(terrasect) is just a cube with four spatial dimensions.

please exlpain wat the fourth spatial dimension is. like wat is its nature or components

it is just math. it is a pretend extra direction for space. instead of (x,y,z), it is (x,y,z,some other letter).

oh i see, is it at all tangible.

somebody here has a 2D representation of one for their avatar. i think it may be terrasect.

wat is the hyper cube used for do u know. a model for something?

idk. afiak, it is just math. it may be used in a kaluza-klein(sp?) thype thing or for one of the string theories or m-theory.

Here are some threads that talk in more detail about higher dimensions and hypercubes. I've done the search parameters so the word hypercube will be highlighted in red:

its nothing other than concept. if your asking for some tangible meaning in it your going to be sorely dissapointed. were 3 dimensional. our brains arent even equiped to understand the vastness of our own universe in its 3 dimensions. a four dimensional object is meaningless to us.

Theres actually a simple way to understand a 4th dimension... possibly more, however it technically couldn't be called a 4th spatial dimension. Anyways, if you just added gradient as a 4th dimension... then you'd see the 3d object, the the 4th d made by the light / darkness of the gradient.

You could even add another if you made another gradient using 2 colors. Get creative, and you could probably think of many ways to "add" dimensions to an object.

o right , kewl. thanks for ur response

Or you could use time for the 4th dimension. So a unit hypercube would be a unit cube which existed only for one unit of time. It would not exist, then suddenly flick into existence, last a unit of time and disappear again.

(I will leave the Minkowski metric to one side...)

That'd be a bit hard to measure though lol... if time was another dimension, it would have to be able to accelerate, decelerate, speed up etc.
