The 4th dimension is a reality, not man made. The 4th dimension is not like the other three dimensions. The mathematics and physics of the dimensions are not understood by most people.
The first three dimensions are vector dimensions and describe the three dimensions of space say , x,y and z. These dimensions were the first dimensions discovered and they are thought to be real dimensions. Real dimensions are like real numbers, their square is a positive number. The truth is the first three dimensions are vectors and are geometrical dimensions. Vectors have relationships like parallel and perpendicular. so v1 and v2 can be parallel to each other or perpendicular to each other. The relationahip betweenvectors involves the angle between them so v1.v2 = v1v2cos(a) and if cos(a) is zero the angle is an odd multiple of 90 degrees, perpendicular. The cos(a) is unity if the angle is an even multiple of 90 degrees. Minus unity means the vectors are Parallel, pointing in the same directon. Plus Unity means the vectors are anti-parallel, the vectors are pointing in opposite directions.
Everyone is roughly familiar with the vector dimensions, except that scientists and mathematicians want the square of vectors to be positive not negative. This is a mathematical defect that ruins vectors.
The 4th dimension is not a vector it is a plain old real number sometimes called a scalar number. Sclars or eeal have positive squares. Scalars are not vectors. Scalars are critically important in science and mathematics. The reason is best understood when you ask the question "What happens to the vectors when you multiply two parallel two vectors v1 and v2? The answer is, the product of two parallel vectors is not a vector! This is like smashing two Oranges together and the oranges disappear and turn into a banana. This is called lack of Closure in mathematics. Closure says that If A and B are vectors, then AB is a vector. You could say Human's beget Humans and fish beget fishes. This is the idea of Closure. Vectors don't have Closure. In Physics they would say that vectors transmuted into a real number. Physicists would create a table of "particles Realtionships". Two reals produce a real; a real and a vector produce a vector; two vectors produce a negative real if parallel or a positive real if anti-parallel; two vectors produce a vector if perpendicular; and ususally two vectors produce a real and a vector if not parallel or perpendicular!
This could open up a whole new fiedl of "particle Physics". The simple answer is the 4th dimension! The 4th dimension is a real dimension. This real dimension satisfies Closure. Two vectors produce a real and this is in the 4th real dimension. This dimension saves Closure because now the the elements are called quaternions. A quaternion is the sum of a real and three vectors, thus making four dimensions thus quater, Latin for 4.
If A and B are quaternions, then AB is a quaternion. Ths 4th dimesnsion has units like the three space dimensions - meters, r=ct is the fourth dimension where c is the speed of light and t is time. both c and t are real numbers and reals time reals gives reals. The speed of light c is a real number not a vector, thus the veclocity of light is wrong, because velocity denotes a vector not a real.
Man did not make the 4th dimension. You could say the 4th dimension was made when God said "Let there be Light!"

What are higher dimensions and what do they look like?
A higher dimension is exactly what it sounds like: a dimension that is different (higher) from length, width, and depth. Our world is in three dimensions, and a higher dimensional universe would have four or mroe dimensions.
What is the difference between many universes and many dimensions?
a) A dimension is a plane of existence or an aspect of a feature i.e. a shape or situation b) A universe is everything that exists, it also includes itself We experience four dimensions (length, width, height and time), but some theories (M-Theory) suggest 11-dimensions. The geometry of our physical universe is three-dimensional. Answer2: a) The geometry of our Universe is four dimensional; one real dimension r=ct and three vector dimensions v= Ix + Jy + Kz. This is called Quaternion Space, the sum of a scalar or real and three vectors. A point in our Quaternion space is p= r+ Ix + Jy + Kz = r + V = [r,V]. Relativity Theory Space-time is x + y + z + ict, this is not a four dimensional space. )b A universe may have many dimensions. Many Universes differ from many dimensions because a Universe is different from a dimension. A dimension is a direction and a universe is not a direction.

What type of universe do we live in?
I believe there is only one type of universe, a Quaternion four dimensional Universe. This Quaternion Universe has one real dimension and three vector dimensions. The universe has two "states", the Boundary state and the Internal state. The Boundary state is a minimum size, around r=150E24 meters. The Internal state is much larger than 150E24.
Why does subraction does not exist?
technically math does not exist because you cant just look at something and indentify it as a number ie: there are four fish and you point to the tank and say that is four. To answer your question subtraction does not exist because it can be put in terms of adding a negative number ie: 5-4=5+(-4)
Does everything in world exist in three dimension?
No. Everything in our world is four dimensions. 3 dimensions of space, and 1 dimension of time.

In what dimension do we see the world?
We see the world in 4D or in other words four dimensional. Slight correction: We being 3-d creatures can actually see the world in 3-d only, although we are continually travelling in the fourth dimension(the time dimension). If somehow we can see this world in 4-d then wemay thentravel in time.
What are higher dimensions and what do they look like?
A higher dimension is exactly what it sounds like: a dimension that is different (higher) from length, width, and depth. Our world is in three dimensions, and a higher dimensional universe would have four or mroe dimensions.
What does it look like in a tesseract?
A tesseract is a hypothetical four-dimensional figure (which does not actually exist).
What is four-dimensional?
Four dimensional usually refers to a 3D environment that changes over time. Here the 3D space could be represented by the axis of a 3D graph. i.e. one axis is forwards/backwards, one is left/right and the third is up/down. The fourth dimension is time. So four-dimensional usually refers to a 3-dimensional space that changes over time.
What happens when a thing from the fourth dimension enters our dimension?
If it was a 4D character (e.g Bill Cipher) it would look odd. If a 3D character entered a four-dimensional space, it would be the world of optical illusions. A 4D character can adapt to the optical illusions, but a 3D character wouldn'tThe third dimension has length, width, height, and depth. The fourth dimension has length, width, height, depth (also illusions), and time. So a fourth-dimensional character (in a third dimension) can control time, so it can stop a computer falling, clouds moving, even a human or animal jumping.
Is it possible three-dimensional space to draw or make a tesseract?
A tesseract is a four-dimensional object, therefore it is impossible to fully portray in three dimensions. However, there are several methods for limited portrayals of tesseracts: a three-dimensional shadow can be shown (just like a 'normal' shadow is 2D of a 3D object); a two-dimension or three-dimension projection can be constructed with the fourth dimension shown at 45° angles to the Z-dimension (in this way two parallel cubes are drawn with each similar vertex connected by a line); or the fourth dimension can be assumed to be time, and an animation of three-dimension projection altering as it rotates around itself.
What is the fifth dimension?
The fifth dimension is a hypothetical construct. Let's start with the dimensions below and work our way to the fifth.A point is a zero-dimensional object and has an indeterminate size.A line connects two points and it has one dimension: lengthA two-dimensional object has length and width.A three-dimensional object has length, width, and depth.The above concepts are easy enough to understand. Here is where it starts to get sticky. The fourth dimension is considered to be time. We live in a three dimensional universe, where there is length, width, and depth. However, we can only exist at one point in time at any given moment. In the three dimensional world only our present self can exist. Hypothetically, in the fourth dimension, we can exist at all points in time, so our past, present, and future selves exist simultaneously.Thus, a four-dimensional object is a time line.The fifth dimension contains different possible time lines depending on the choices you make or chance events. In other words, let's say you are born in New York to a middle class family, go to school, then college, study to become a doctor, become a doctor, get married, have children, and then die. That would be only one time line. In another time line, you could be born in New York to a middle class family, go to school, then college, study to become a doctor, become a doctor, but die in a car accident before you can have a wife and family. That is an entirely different time line. In yet another time line, the situation could be completely different.I hope I explained it clearly enough for you to understand.
What is meant by 4th dimension?
When a reference is used to four-dimensional co-ordinates, it is likely that what is referred to is the three spatial dimensions plus a time-line. Taken from Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Fourth_dimensionLengh X Width X Height X Time + Love :) ANSWER Not counting virtual reality, everything you know of is four-dimensional. The fourth dimension is probably the hardest dimension to understand. It's made up of 4 parts, length x width x depth x time( L x W x De x t). Therefore, there really is no visual object that is not four-dimensional.
Is a piece of paper 2 dimensional or 3 dimensional?
All objects in our universe, including paper, are actually 3 dimensional. Paper may be very thin, but the thickness of paper is larger than zero. If it had a thickness of zero, it could not exist. But when we write on paper, we are usually using it to create pictures that are effectively two dimensional. Of course, even ink on paper, or pencil or any other writing medium still has some thickness, but we do not see the thickness so we think of it as two dimensional. In Einsteinian physics, the objects in our universe are actually four dimensional since time is also a dimension.
What is a four dimensional shape?
a four dimensional shape cannot exit within our own reality because we live and occupy space in 3 dimensions and no one can change that however we can view 4 dimensional objects in a 3 dimensional world however the object itself is not occupying space in four dimensions but emulating the way it could look in a 3-d world, a 4-d shape is one in which it would exist on 2 separate planes but only occupys one e.g the top of your stairs is also the bottom but when you get there your at the top even though you just walked down.
