A journey to the 4th Dimension

  

             There was a day when dimension was unknown to humans. So they thought aliens as some type of Gods. This is still not sure whether gods are true or they are some aliens from different planet. If they are some aliens,then we can say that we are not alone... But how they came to earth. Because still our scientists are not able to find their home. So we can say that they are living far from us. If it is true then the question is how they were coming to this earth in a very short time ? Is there and secret path or some other way which is better than space and may be the way is unknown to us. May be that is the way where speed increases. If this is true than there may exist some other dimension other than third dimension. May be this the 4th dimension......

What is 4th dimension?

Some believe it is time. Mathematicians and scientists focus on the fact that it is a direction different from all direction in normal space.( A sentence from wikipedia)

4^th Dimension is that area which is created by the cross of 4 spaces.

Explanation:-0^th Dimension is created by a simple point. 1^st Dimension is created by a straight line that goes through 0^th dimensional point. 2^nd dimension is created by cross of 2 straight lines in 90 degree.

3^rd dimension is created by the cross of 3 planes in 90 degree. So it can be imagined by the cross of 4 spaces in 90 degree.

Small discreption

The 0^th Dimension

An object in the 0^th dimension consists of only a point. The name of the point is origin, from all the axes are originated.

The 1^st Dimension

An object in the first dimension consists of only one of

 the fundamental units. For example a line only has length. 

  A line is one dimensional

                                                                     
                              

The 2^nd Dimension

An object in the second dimension consists of two of the fundamental units.  For example, a square has a length and a width.  Notice that is you stack lines on top of each other you creates a square, or an object in two dimensions.

 

The 3^rd Dimension

An object in the third dimension consists of three of the fundamental units.  For example, a cube has a length, width and height.  Notice that is you stack squares on top of each other you creates a cube, or an object in three dimensions.

The 4^th Dimension

An object in the fourth dimension consists of four units.  For example, a hypercube has a length, width, height and a fourth dimension that is perpendicular to all three of the other units.  Look at the corner of the room and imagine extending a line perpendicular to all three lines at the intersection.  If you can visualize stacking cubes into this fourth dimension you create a hypercube.
