#### For your perusal, here’s a handy pictorial reference to the vast, terrifying vistas of space-time

According to superstring theory, there are at least ten dimensions in the universe (M-theory actually suggests that there are 11 dimensions to spacetime; bosonic string theories suggest 26 dimensions).

That’s a bit of a mind-boggler: Most people understand the basic three dimensions, and many know that the fourth dimension is probably time. But what, exactly, are the dimensions beyond those?

Inspired by a recent article at Phys.org that broke down the main ten; here’s a handy visual guide to orienting yourself to superstring theory and your place in the infinite, neverending mindf*ck we call “reality.”

#### The First Dimension: Length

The first dimension is length, or x-axis—a straight line, with no other characteristics.

#### The Second Dimension: Height

Height, or y-axis, can be added to the length to produce a two-dimensional object, such as a triangle or square.

#### The Third Dimension: Depth

Depth, or z-axis, can be added to the previous two dimensions to produce objects that have volume, like a cube, pyramid, or sphere. This is the end of the dimensions that are directly physically perceptible by human beings. All dimensions beyond the third are theoretical.

#### The Fourth Dimension: Time

The fourth dimension is the position in time occupied by a three-dimensional object. (Image via.)

#### The Fifth Dimension: Possible Worlds

The fifth dimension is a world slightly different than ours, from which we could measure similarities and differences to our own world. (Image via.)

#### The Sixth Dimension: A Plane of All Possible Worlds With the Same Start Conditions

The sixth dimension is a plane containing all possible universes with the same start conditions as ours; i.e., the Big Bang.

#### The Seventh Dimension: A Plane of All Possible Worlds With Different Start Conditions

The seventh dimension expands upon the sixth by plotting all possible worlds that begin with *different* start conditions.

#### The Eighth Dimension: A Plane of All Possible Worlds, Each With Different Start Conditions, Each Branching Out Infinitely

Are you dizzy yet? (OK, OK, look, there’s a point beyond which the mind of humanity is unable to cognize without resorting to rave flyer graphics.) (Image via.)

#### The Ninth Dimension: All Possible Worlds, Starting With All Possible Start Conditions *and* Laws of Physics

In each of these dimensions, which represent all possible start conditions, the laws of physics are all *completely different*. (Image via.)

#### The Tenth Dimension: Infinite Possibilities

At this level of complexity, everything that is possible and imaginable exists. Even a world in which you have no student loans.
