Dimensions

I really wrote this yesterday.

I spent some time today trying to comprehend the fourth dimension. It's something that heavily interests me, because it should be so easy, but it's completely impossible.
I started reading The Time Machine by H.G. Wells today, and I don't agree with the idea it presents: that we are already in the fourth dimension. It says that there are the three dimensions of "space" and the one "duration." I still think time is something else entirely. Time can not be a "dimension" because no other dimensions could exist without it. It is somewhat of a base of framework upon which other dimensions are allowed to exist. Under the idea that our dimension is the 4th dimension, than the third and second dimensions could still exist, but in a first dimension, there would either be no time or nothing existing in that time. Any kind of existence would be impossible without both. The whole theory seems flawed to me. While reading it, the way it was presented made it seem, at least, plausible, but upon thinking about it on my own, it just seems full of holes.
These thoughts, however, created a completely different string of thoughts on the subject of dimensions.
A couple of years ago, I asked a friend what he knew about the fourth dimension. At one point, he said that anyone in a dimension could comprehend each before their own, but none after; we can't comprehend the fourth dimension, but we can understand the first and second. This would also mean that any living beings in the second dimension couldn't comprehend the third, but they could understand their own and the first.
This does, however, bring up an issue. Would life even be possible in this theoretical second dimension? There is no proof that such life exists, but it would still be possible. We have created artificial life through animation. What are our own lives really, but programmed machines made of parts? Such a machine could still exist in a second dimension, though I imagine they would look quite different than we do. Even if you look at it religiously, why couldn't God create life in two dimensions? Any way you look at it, it seems wholly and completely possible.
Where we can comprehend all of the dimensions before our own, but none after, I believe we could exist in all of the dimensions after our own, but none before. We could not live in two dimensions, because our bodies were made to exist in three dimensions; they couldn't exist without depth. However, though I don't understand the fourth dimension, I don't think it would be completely impossible for us to exist there, or in the fifth or sixth. Our three dimensions still exist, but with a one, two, or three more dimensions tacked on. Under this theory, life in the second dimension would still be able to exist here in the third. Their dimensions -- length and width -- still exist here, there just happens to be another dimension -- depth.
So, if a two-dimensional being were to somehow gain entry into the third dimension, it could still exist, but it would have no depth, making it completely invisible.
Perhaps the second dimension even exists among us; all around us but completely invisible. Within that would be the first dimension. We would be within the fourth, un-mingling and unknowing.
Though that may be a bit of a stretch, I still think that it would be possible for life to live within the second dimension (maybe even all dimensions, for that matter) and for that life to live among us, invisibly. Even if that isn't where they always exist, these two-dimensional beings could be very technologically advanced, and they could find a way to access our dimension. I would like to visit the fourth dimension in such a way.
I do hope human technology will move in that direction someday; toward comprehending and/or viewing other dimensions. It seems to be something we barely ever think about. No matter how long I sit here, trying to comprehend the fourth dimension, I'll never understand it, but that doesn't mean I should forget all about it. If it could be possible for us to exist within the fourth dimension, it is worth thinking about how we can gain entry.


Note: While rewriting this, I had another thought. Basically, the higher dimensions probably think about this sort of thing more and more as the numbers get higher. Any life in the second dimension couldn't notice the pattern of adding perpendicular lines to create new dimensions, because you can't notice any patters between two things. I doubt they would even have any thoughts regarding "dimensions." How would they know? Indirectly, this would probably cause those in higher dimension to be significantly more intelligent than life in dimensions below them. We would probably look like ignorant fools to anyone in the fourth dimension.
I doubt we'll be getting any visits from anyone in the second dimension. They're probably not even as "technologically advanced" as we are. We also couldn't get visited from someone from any fourth dimension, though, because that's not possible. I guess we'll have to just sit here being ignorant, as always.
