Physics, Astronomy & Cosmology / What is the 4th dimension?
« on: 23/10/2003 04:28:10 »
I had an option of doing a project on the 4th dimension last year, I didn't actually do it but I looked at some books and website and things, and most of them were about the 3 dimensions we know, and that the 4th dimension is time. I don't really understand this concept, but one way I saw it related was this: Let's say you've got a little square isolated to the 2nd dimension. He can move up and down on the X and Y axes (plural for axis), but he can't move vertically through the height dimenson. Since he can't see it or ever actually move in this way, there's really no way for him to possibly understand this. You can try to explain it to him, but there's no way he can really know unless he expieriences it himself.
So I suppose if there were a creature that could use the 4th dimension it could move in and out of our vision using the 4th dimension, which I suppose could be time, meaning he could time travel? Anyway, I was just wondering what other theories were out there about this topic, and if there has ever been any speculation about something less than 1 dimension or more than 4.
