My Non-Paradoxical Explanation of Time and Space
One night, when I was in the shower, I was frustrated about how the 4th dimension was so different compared to the first three. Keep in mind the fact that I have Asperger's Syndrome. I suddenly had a moment of inspiration. "What if they aren't so different? What if they follow the same pattern? What if the difference between dimensions two and three are the same as between three and four?" I then started scribbling in a notebook for the next few hours. This is what I got:
The 0th dimension is a dot. No length, no width, no height. Zero dimensions.
The 1st dimension is a line. This single dimension is usually called length.
The 2nd dimension is like a square. They have two dimensions, which are titled two of the three following: length, width, and height.
The 3rd dimension is like a cube. It has three dimensions, being length, width, and height.
It follows the pattern:
The 4th dimension is like a cube, stretched out through a timeline. It has four dimensions, being length, width, height, and time!
The 5th dimension is like a cube, stretched out through multiple timelines. It has five dimensions, being length, width, height, time, and what is probably an unnamed measurement whatchamacallit.
Here is another pattern, that really makes light-bulbs go off in people's heads:
The 0th dimension is a dot.
The 1st dimension is a line. A line is made of an infinite number of dots strung together.
The 2nd dimension is like a square, which is made of an infinite number of lines strung together.
The 3rd dimension is like a cube, which is made of an infinite number of squares strung together.
The 4th dimension is like a cube stretched out through a timeline, which is made of an infinite number of squares strung together.
ETC.
Because of this pattern, there are an infinite number of dimensions. Given the fact that there are infinite dimensions, separations between dimensions are an illusion we created by giving them a name. A dimension is just a way of classifying a part of something that is already there, but everything has infinite dimensions. Paper still has thickness. Paper still moves through time. The paper still exists in alternate timelines. Et cetera.
I've also used these patterns to show how time flows, how time travel would work, etc., but I'm short on time. I'll come back and edit this post within the next few days.

I find some of Rob Bryanton's videos helpful in understanding dimensions but my brain malfunctions with these ideas after a while: https://www.youtube.com/user/10thdim

Re: My Non-Paradoxical Explanation of Time and Space
One thing to bear in mind: the concept of dimensions is a mathematical construct. For sure, it is useful for modelling the observed world that we call reality, but you can go wrong if you start to confuse the map with the territory - to think that those dimensions are reality. You're quite right in observing that it is perfectly mathematically consistent to just keep adding more dimensions, obeying the rule that each new dimension is simultaneously perpendicular to all of the previous ones. But that doesn't necessarily mean you've made any empirical discovery about the observable world. It means you've used some deductive mathematical reasoning to make a discovery about mathematics.
The mathematical concept of an n-dimensional space is useful for modelling and visualising various different aspects of the physical world. Not just the thing that we normally refer to as space and think of as having 3 dimensions (or space-time that we think of as having 4 dimensions). That's just the most well known one.
Another well known use of this mathematical model called dimensionality is the concept of "phase space". As an example of this, think of all the numbers required to entirely define the state, at a given instant, of a point particle at a location in physical space. It is 6. You need 3 for its position and 3 for its velocity. Now imagine a system of n particles (where n is any whole number) like, for example, an ideal gas. The number of numbers required to define the state of that gas is 6n. Now you can imagine a "space" with 6n dimensions. In that multidimensional space a single point represents the entire state of that gas - the state of all its contituent particles. A line in that space could represent the evolution of that gas over time.
These are the ways in which the concepts of dimensionality and space can be used to manage the complexity of modelling complex systems.

There maybe some different things, the spirit world, the warm holes, ether and others, but physically we know only know these four and the time.

Re: My Non-Paradoxical Explanation of Time and Space
I also like more the larger cosmology, the philosophical cosmology than the astronomical cosmology.
These 5 can be seen in the reality. In mathematics there can be more, but in the physical reality we now can see only these 5. Of course there can be other realities, the spirit world, the things of Quantum Theory and so on, but they are not clear yet for us.

Re: My Non-Paradoxical Explanation of Time and Space
Consider an ordinary timeline. This is mapping time as space.
The timeline itself is the fourth dimension of space (or "space-time").
The plane on which the timeline is drawn is the fifth dimension of space.
The "room" on which the plane exists, on which the timeline is drawn, is the 6th dimension of space.
If you imagine our present-day Universe as a dot moving through 3-D space, much like a speck of dust floating around a room, you can visualize 6 dimensions of space. The 3 dimensions of space in which the speck of dust is moving through is 3 more dimensions of space than the speck of dust itself, which is representing our 3-D Universe. Therefore the room the speck of dust is traveling through represent the 4th, 5th, and 6th dimensions of space, which, due to the fact that our 3-D Universe is moving relative to, gives us our perception of time. This is why we have the idea of a "before, now, and after" ---> it's because our entire 3-D Universe is moving within higher dimensions of space....

Re: My Non-Paradoxical Explanation of Time and Space
This all we can rationally say as philosophers. The models in astronomical cosmology are a little different thing. The philosophy is a larger cosmology.

Further to the questions approached in this thread: I realise I do not have the mathematical training or aptitude to comment usefully nor to assess the comments of others, with regard specifically to matters of Physics in general and posited relationships between purported 'dimensions'.

Re: My Non-Paradoxical Explanation of Time and Space
Yes, and those three spatial dimensions make the form through which the material world is for us. And because we exist temporally, that is, our being consists of successive experiences of the world, also the world must be temporal, consisting of material events. We measure those events with our clocks, and now the situation becomes a bit more complicated, because those clocks go slower or faster depending on our position in relation to the clocks. Space and time get intertwined, and we have the concept of space-time, which is the result of applying and extending our original, subjective time to the material world.Surreptitious57 wrote:There can only be three classical spatial dimensions for that is the only number we can actually
