how does 4 demension not exist and why cant a human never see it?

Answer 1

The concept of a fourth dimension is one that is often described in considering its physical implications; that is, we know that in three dimensions, we have dimensions of length (or depth), width, and height. The fourth dimension is orthogonal to the other three spatial dimensions. The cardinal directions in the three known dimensions are called up/down (altitude), north/south (longitude), and east/west (latitude). When speaking of the fourth dimension, an additional pair of terms is needed. Attested terms include ana/kata (sometimes called spissitude or spassitude), vinn/vout (used by Rudy Rucker), and upsilon/delta.

Usually, the fourth dimension is identified with time. In this case, the concept of an additional spatial dimension would be referred to as the fifth dimension.

Answer 2

Just because scientists tell something you need not accept it blindly. Einstein or other scientists are not perfect. They are right many times but not all the times.

Time cannot be considered as a dimension. In physics we equate similar things. For example during calculation etc metric system cannot be combined with pound system. I am giving one example.

We are talking about physical material. It can have only 3 dimensions. How can you connect it with non-physical issue like time.

For physical matters or stuff you can have only 3 dimensions.

Time is not physical matter. You cannot put it in the same basket.

Universe is a physical matter. It can only have 3 dimensions.

You can use time together with 3 dimensions for some purposes. But you cannot use it for a dimension purpose as time is a different stuff compared to physical stuff like planets, galaxy, universe etc.

Answer 3

we do not perceive 4 spatial dimensions (some consider time a 4th dimension and there is useful math based on that concept)

there is probably no such thing as a 4th dimension in the real universe, it is merely a math construct

think about it, try to imagine a block of wood that had more than the three defining dimensions

a line has one spacial dimension (it is completely defined by its length)
a plane has two (you could call them width and depth)
a cube has three (call them width, depth, and height)

what would have four? nothing we can imagine

Answer 4

The fourth demension is Time.

Answer 5

In traditional physics, as expounded by Einstein, the 4th dimension is "time," though space-time is considered an unavoidably connected construct.

In order for anything to exist as we can know it, it must have volume (three dimensions) and duration in time, because we are three dimensional, chronologic beings, and we can only concretely perceive our own sphere (spiritual or extra-sensory possibilities notwithstanding).

Answer 7

What IS the fourth demension?

Answer 8

Please learn to spell! In a sense, time is a 4th dimension, but there are non-Euclidean geometries with four or more spatial dimensions. String theory has eleven dimensions. That may be beyond your comprehension. Einstein failed to devise a Unified Field theory, but String Theory may achieve that. There are many things one cannot see. A three-dimensional being is limited to his three, not four to eleven.

Answer 9

The fourth dimension is time. We can't see it because it is completely subjective to your circumstances. Time seems to drag in school, yet flies by in the summer. It's all about perspective.

Answer 10

no no no...the demesions are:
1. a dot
2. a square
3. a cube
4. a tesseract (humans are yet unable to construt one, or master the idea of 4-D)
5. time
