Lol, I need to pay more attention to the auto spell correction. I'm not limiting myself, I get the question and I've thought about it. I've probably come up with all the ideas everyone else did, but, in the end, the question is faulty. If there's only two, there can't be a third. If there was, it look like what we see now with an x y and z. I completely understand what you're getting at, though. And for whoever said the universe is expanding: expanding into what? Now there's your philosophical question.
Dude, you sound like me after a smoke a big one I think it's like the old Final Fantasy, once you reach the edge of the world, you reappear on the other side! No?! And what if you could see in 4D? What would it be? How about seeing a color you never saw before? Too much man, too much...
Actually, there are colors we can't see. They fall into the spectrum of ultraviolet light. You can see that they're there with UV sensitive cameras, but we can never see what they really look like with our eyes and brains. Also, those colors are in front of you face right now, you just can't see them. Ultraviolet light isn't a special type of light, it's just a high frequency. All colors are a different frequency, but we can only perseve a certain range. Now that I find trippy.
Dude, every night when I get home Hell, I wish some of you TA'ers in SF would come on over to my house for a smoke & talk session
Ok, so take the 3D universe, imagine it is 2D, and then try to think of it in 3D? You're right, I really don't quite know what you're asking. But that aside, I kind of get what the idea is behind your question, even if I don't fully understand the question itself. Like the existence of more dimensions right, greater than our own? Like a 4th, and 5th and so on, which I frequently find myself pondering about. Ignoring this "The 4th dimension is time" crap (which largely has to do with the sheer size and distances in space, you can't look at anything through a telescope without also realizing that the image is in fact, much older than what the current object really is.) the idea of an actual dimension in geometry makes my head hurt. There's an interesting thing on wiki (I'm sure it is other places, but well, wiki is the firs tplace I look) called something, can't remember, and it's basically a model of what the 4th dimension might look like (Ok, looked it up, it's called a tesseract, again, use internet to find out more). They (mathmagicians) say that if you take a picture, which is two dimensional (ignoring the actual dimensions of the photograph itself, the paper), there is enough information in the photograph (shadows, focus, etc) for our brains to "see" the three dimensions. And the image provided on the wiki page of a tesseract supposedly provides enough information to allow our brains to contemplate a fourth dimension. But I don't know. It is very difficult. Like trying to think of a color you've never seen. So I'm still not sure, I think I get the basic premise of the question, but who knows.
Here's something else to ponder. Imagine that multiple realities are actually real. There is an infinite number of them but instead of the theory that they are all unique bubbles floating in some kind of mixture, what if it was more abstract in the sense that everything and anything within this universe are in fact from all other realities. Imagine yourself as the endpoint to a needle who's base resides in one reality. The needle head itself though, has pierced through that reality and is now inside of another. Imagine you're the head of that needle. I wonder how you push and pull the needle. What do you think?
