I remember ages ago having a heated argument with one of my classmates during our lunch hour about the fourth dimension. He believed it was where our soul went after death, and I believed it was time (temporal dimension).
When you look at the psychics of it, many scientists believe that the temporal dimension is the fourth. But the problem I see with this now is it does not correlate to the first 3 and it should, or be termed or defined as something else.
I’ll explain why. In physics spatial dimensions have a classical theory describing three physical dimensions: the basic directions in which we can move are up/down, left/right, and forward/backward. Movement in any other direction can be expressed in terms of just these three. In its simplest form: a line describes one dimension, a plane describes two dimensions, and a cube describes three dimensions.
Example Co-ordinate Systems:
So you see the first three dimensions are spatial environments. Where Time is not. Have you ever read the definition of “time” in the dictionary?
Small excerpt from Merriam-Webster Dictionary
Noun- Measured or measurable period. More broadly, it is a continuum that lacks spatial dimensions. Philosophers have sought an understanding of time by focusing on the broad questions of the relation between time and the physical world and the relation between time and consciousness. Those who adopt an absolutist theory of time regard it as a kind of container within which the universe exists and change takes place, and believe that its existence and properties are independent of the physical universe. According to the rival relationist theory, time is nothing over and above change in the physical universe. Largely because of Albert Einstein, it is now held that time cannot be treated in isolation from space (see space-time). Some argue that Einstein's theories of relativity vindicate relationist theories, others that they vindicate the absolutist theory. The primary issue concerning the relation between time and consciousness is the extent, if any, to which time or aspects of time depend on the existence of conscious beings. Events in time are normally thought of in terms of notions of past, present, and future, which some philosophers treat as mind-dependent; others believe that time is independent of perception and hold that past, present, and future are objective features of the world.
That is just a small excerpt. It is one of the longest descriptions you will ever read in the dictionary.
It is also interesting to note that (if you ever go) in the Astral Realm, time appears to move at a different rate there, compared to here.
In physics, three dimensions of space and one of time is the accepted norm. There are theories that try to unify different forces and such—these theories require more dimensions. Superstring theory, M-theory and Bosonic string theory respectively posit that physical space has 10, 11 and 26 dimensions. These extra dimensions are said to be spatial. However, we perceive only three spatial dimensions and, to date, no experimental or observational evidence is available to confirm the existence of these extra dimensions. A possible explanation that has been suggested is that space acts as if it were "curled up" in the extra dimensions on a subatomic scale, possibly at the quark/string level of scale or below.
Some complex networks are characterized by fractal dimensions. The concept of dimension can be generalized to include networks embedded in space and characterize by their spatial constraints.
So is the Temporal Dimension the 4th Dimension? I don’t think so. I think it needs its own classification. Dimensions should be spatial measurement only. To clarify, parallel dimensions probably have measurable spatial features, I think it is safe to classify them in with dimensions as well. Even the Astral Realm I would consider as a dimension, but Time...?
I use dimensions heavily in my next book because the character Kealin becomes trapped in one different from where she belongs.
I know it seems like such a nit-picky thing to debate with myself, plus the guy I had lunch with ages ago doesn’t even know the debate is still going on in my head. What a wack-a-doodle I am.
