Is there such this as 4-D?

Question

Hey i was wondering if there is such thing as 4-D, and if there is, what is it?

thanks!

Answer 1

The fourth dimention is time and space I do believe.

But if it isn't that then just imagine a picture that it is possible to draw, but you could not represent physically such as;

Answer 2

yes there is such thing as 4-d...you can find 4-d movies or stuff at amusement parks...4-d movies keep the 3-d but take it to a whole nother level...they add other things that appeal to your scents, such as touch, and smell...for instance at one part when a big boi cannonballs into a pool and makes a big splash, as the water comes to the camera making it look like your gooing to get wet, water from a shooter will make you wet to give you another demension of movie going experience....or it might be a simulator of type thing

Answer 3

the first three dimensions are Spatial  ... width, length, depth

the fourth dimension refers to time

... so an object occupies a certain physical space at a certain specific time.

interested in the 5th dimension?  it's quite mind boggling! check this out:  http://www.msnbc.msn.com/id/13070896/

Answer 4

The fourth dimension is a temporal one.

Objects that move at a rate of motion less than the constant speed of light move through the four relative dimensions of the universe.

A fourth spatial dimension would be a different story.

It would mean an extra set of parameters in the spatial context.

1st dimension = foward-back

2nd = 1st + up-down

3rd = 1st & 2nd + left-right

and the fourth would be all of the above plus

maybe something like inside-outside???

It is difficult to imagine a fourth spatial dimension but we can see what its 2d shadow looks like just like we can draw a 2d shadow of a 3d cube.

Time is the often called the fourth dimension and Einsteins special relativity has empirically confirmed that a fourth temporal dimension exists.

Time as a dimension is a very real quality of our universe.

Answer 5

time

Answer 6

Okay, this is going to hurt your head.

A line has one dimension: length.

Draw a line perpendicular, and you have two dimensions: length and width.

Now draw a line perpendicular to both those lines and you have three dimensions: length, width and depth.

Okay, ready? Now draw a line perpendicular to those three lines and you have four dimensions.

Now, ask me about my time machine ;)

Answer 7

No.

Answer 8

Well, technically yes.  The first three dimensions are length, width, and height.  The fourth dimension is time.  So we are four dimensional.

Answer 9

When in doubt-ask wikipedia:

although I do remember talking about this in physics, and some other math class I had in high school, I think.

Answer 10

Well, I saw a "4-D" movie once and it was 3-D but with effects like wind, rain, and little things like that. Like, of course it didn't start pouring in the movie theatre, but the back of seats in front of you would spray you and stuff. haha good fun. I don't know if thats really 4-D though, or if they just called it that for fun...
