The first dimension, as already noted, is that which gives it length (aka. the x-axis). A good description of a one-dimensional object is a straight line, which exists only in terms of length and has no other discernible qualities. Add to it a second dimension, the y-axis (or height), and you get an object that becomes a 2-dimensional shape (like a square).
The third dimension involves depth (the z-axis), and gives all objects a sense of area and a cross-section. The perfect example of this is a cube, which exists in three dimensions and has a length, width, depth, and hence volume. Beyond these three lie the seven dimensions which are not immediately apparent to us, but which can be still be perceived as having a direct effect on the universe and reality as we know it.

Scientists believe that the fourth dimension is time, which governs the properties of all known matter at any given point. Along with the three other dimensions, knowing an objects position in time is essential to plotting its position in the universe. The other dimensions are where the deeper possibilities come into play, and explaining their interaction with the others is where things get particularly tricky for physicists.
According to Superstring Theory, the fifth and sixth dimensions are where the notion of possible worlds arises. If we could see on through to the fifth dimension, we would see a world slightly different from our own that would give us a means of measuring the similarity and differences between our world and other possible ones.
In the sixth, we would see a plane of possible worlds, where we could compare and position all the possible universes that start with the same initial conditions as this one (i.e. the Big Bang). In theory, if you could master the fifth and sixth dimension, you could travel back in time or go to different futures.
In the seventh dimension, you have access to the possible worlds that start with different initial conditions. Whereas in the fifth and sixth, the initial conditions were the same and subsequent actions were different, here, everything is different from the very beginning of time. The eighth dimension again gives us a plane of such possible universe histories, each of which begins with different initial conditions and branches out infinitely (hence why they are called infinities).
In the ninth dimension, we can compare all the possible universe histories, starting with all the different possible laws of physics and initial conditions. In the tenth and final dimension, we arrive at the point in which everything possible and imaginable is covered. Beyond this, nothing can be imagined by us lowly mortals, which makes it the natural limitation of what we can conceive in terms of dimensions.
First Dimension
A line connecting two points. There is no depth and no height, only a width. You can call this the x-axis.
First dimension
Second Dimension
Now we have added height or the y-axis. Think of any flat figure, like a triangle.
Second dimension
Third Dimension
We have now added depth or the z-axis. This is the dimension in which we experience the world. It includes volume and the ability to obtain cross sections from objects. You can think of this dimension as space without time.
A three dimensional triangle is now a pyramid
Fourth Dimension
The fourth dimension is not a spacial one but it consists instead of time. Time helps plot an object’s location in the universe and also adds a way for the third dimension to change. Remember how the third dimension is space without time? Well now we officially have space time.
“Time is relative, okay? It can stretch and it can squeeze, but… it can’t run backwards. Just can’t. The only thing that can move across dimensions, like time, is gravity.” -Interstellar, dir. Christopher Nolan.

Fifth Dimension
From here on we begin to see the higher dimensions. These are imperceptible to us, scientists believe, because they exist on a subatomic level. These dimensions are curled in on themselves in a process known as compactification. The dimensions here on out really deal with possibilities.
In the fifth dimension there would be a new world that would allow us to see the similarities and differences between our world and this new one, existing in the same position and having the same beginning as our planet, i.e. the Big Bang.
Fifth dimension
Sixth Dimension
The sixth dimension is an entire plane of new worlds that would allow you to see all possible futures, presents, and pasts with, again, the same beginning as our universe.
Sixth dimension
Seventh Dimension
In the seventh dimension up through the ninth, we now have the possibility of new universes with new physical forces of nature and different laws of gravity and light. The seventh dimension is the beginning of this, where we encounter new universes which have a different beginning from ours. That is, they were not born from the Big Bang.
Seventh dimension
Eight Dimension
This dimension is a plane of all the possible pasts and futures for each universe, stretching infinitely.
Eight dimension
Ninth Dimension
The ninth dimension lays bare all the universal laws of physics and the conditions of each individual universe.
Ninth dimension
The Tenth, or Eleventh Dimension
Some scientists believe that the multiverse has only 10 dimensions while others put that number at 11. However, a universe cannot have more than 11 dimensions because of self consistency — they become unstable and collapse back down into 11 or 10 dimensions. At this point, anything is possible. There are all futures, all pasts, all beginnings and all ends, infinitely extended, a dimension of anything you can imagine. Everything comes together.
Tenth or eleventh dimension
String theory also has an answer for the mysterious moment before the Big Bang occurred. The universe then consisted of nine perfectly symmetrical dimensions and one time dimension. The four fundamental forces — which I cover in my Quick Summary of the Universe — gravity, weak nuclear, strong nuclear, and electromagnetism were held together under extremely high pressure and temperature. When it became unstable, it broke into the dimensions of time and space we know today. The first four are perceptible to us while the last six or seven were reduced down to a size smaller than an atom.
While the idea of a multiverse is fun in terms of science fiction and daydreaming, it’s also mathematically sound and would provide the framework for a theory of everything — which is exactly what string theory attempts to be. It would be a beautiful coming together of science, math, and mysticism
