It's hard to explain, but I'll try to in few words:
Imagine first of all 1D, 2D and 3D.
Try to picture a figure of 2D intersecting the world of 1D. Draw it on a paper, a square (2D) trying to intersect the world of a line (1D). From the view of point of the line, as it's in a world of only one dimension, it would only appear (the square) as a line, but moving. The square's shapes never changes, but as it intersects the line's dimension, the line itself sees the square as a movement in one dimension.

Now, picture for yourself a 3D object intersecting with the world of 2 dimensions. Imagine how a square would see that object from his own point of view (2D). It would always see it, but in two dimensions of course, and MOVING.

Now, the point of view of a square, watching a line in 1D, is seeing it ALL. The square, from its 2D world, can see all the content of the one dimension world. The same goes for the 3D seeing the 2D world.

The 4th dimension is the same, it can see all the content of the 3D world, in other words, everything means all the moments of the 3D universe, which means, past, present, and future.


It is really hard to explain this with just words, but this introduction MAY, in some way, make you visualize the concept of 4D.
