First dimension: As previously stated, the first dimension is the one that provides its length (aka. the x-axis). A straight line, which simply exists in terms of length and has no other discernible properties, is an excellent description of a one-dimensional entity.
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.
The second dimension has both length and width. Imagine a world that only has two dimensions. Now imagine two-dimensional creatures like those on a playing card; we will call them Flatlanders, a term originally coined by author Edwin Abbott.
The First Dimension (1D)
1D consciousness is pure being. It's not aware of separation — it simply exists without individual identity. 1D is also said to be associated with the Root Chakra, which is focused on the most basic human needs and security, as well as our identity with our planet.
Time operates in the first, second and third as well as theoretical spatial dimensions such as a fourth spatial dimension. Time is not however present in a single point of absolute infinite singularity as defined as a geometric point, as an infinitely small point can have no change and therefore no time.
We live in a world of three dimensions.
Everything around us, from the houses we live in to the objects we use in everyday life, has three dimensions: height, length, and width.
Time arises from motion along fourth space dimension, and hence time is real, not an illusion.
Scientists do not believe there can exist more than 11 dimensions because conditions become unstable and particles naturally collapse back down into 10 or 11 dimensions. The 12th dimension, for example, introduces a second time. While strings can only vibrate in 10 dimensions, membranes can exist at 11 dimensions.
What is the standard? What comes first? The Graphics' industry standard is width by height (width x height). Meaning that when you write your measurements, you write them from your point of view, beginning with the width.
Thankfully, there are no 4D creatures inhabiting our Universe, as they would appear indistinguishable from physics-defying, godlike entities. But what if instead of us being higher-dimensional creatures in our Universe, the Universe itself had more dimensions that it has right now?
Theoretical physicists believe math shows the possibilities of a fourth dimension, but there's no actual evidence—yet. Albert Einstein believed space and time made up a fourth dimension.
Some theorists have even argued for more, up to an indefinite number of possible dimensions. Other physicists suggest that experimental results have thrown cold water on the case for higher dimensions, leaving us only with the familiar three dimensions of length, width and height, plus the dimension of time.
A 12-Dimensional Space is a space in which each point requires a duodecuplet of numbers to describe its position. This makes it a hyperrealm.
When you see the dimensions of an object listed as “length x width x height,” it is referring to the measurement of that object in three-dimensional space. The length is always the longest side, the width is always the middle side, and the height is always the shortest side.
In five dimensions, they are: The 5-simplex of the simplex family, {3,3,3,3}, with 6 vertices, 15 edges, 20 faces (each an equilateral triangle), 15 cells (each a regular tetrahedron), and 6 hypercells (each a 5-cell).
When you tell us the dimensions of the box, they need to be in this order, Length x Width x Depth.
The fifth dimension is a micro-dimension which is accepted in physics and mathematics. It's here to have a nice and seamless tie between gravity and electromagnetism, or the main fundamental forces, which seem unrelated in the regular four-dimensional spacetime.
In mathematics, a zero-dimensional topological space (or nildimensional space) is a topological space that has dimension zero with respect to one of several inequivalent notions of assigning a dimension to a given topological space. A graphical illustration of a nildimensional space is a point.
In bosonic string theory, spacetime is 26-dimensional, while in superstring theory it is 10-dimensional, and in M-theory it is 11-dimensional. In order to describe real physical phenomena using string theory, one must therefore imagine scenarios in which these extra dimensions would not be observed in experiments.
Traveling backward in time is much harder, but mathematics says it is possible through geometric structures called closed timelike curves. A wormhole is one such curve. You would enter it through a spherical opening. Once inside, everything you observed in space would be normal and so would the passage of time.
Movement of an object through spacetime, it tends to warp it's way around in the image above. It's for this reason that time is necessary to be contemplated, as well as why you can't have a dimension without time.
As a universe, a vast collection of animate and inanimate objects, time is infinite. Even if there was a beginning, and there might be a big bang end, it won't really be an end. The energy left behind will become something else; the end will be a beginning.
