The fourth dimension

[Charlatan]

To get into the fourth dimension, you need to pierce a cube, or this world's dimensions, then open it up. To do that maybe you need to do it at sub atomic level? That would be a very small space indeed, so we will try to make objects four dimensional - visually.

Maybe by piercing a space, then expanding atomic structure from within that object we could simulate this concept of the fourth dimension. If you look at a cube and look into the cube, you will be able to imagine a dimension inside of the cube coming out and going around again. To simulate that we need to pierce the cube and expand a cube within the cube, then merge them into the same thing. That means tking two objects and making them the same one, not by merging exaclty, but by intersecting the dimensions or angles so that they are the same thing, while they are not, but they will be the same thing in the end.

But what about people going into the fourth dimension? They could surely have their insides turned out, so we need to be more careful. Maybe if we were to add to the human form, then intersect the objects, we could see a person going into the fourth dimension? If we were to place a human inside a four dimensional space they would enter the fourth dimension, but only be three dimensional, as in energy form they could do that - so maybe with out of body experiences they could go into the fourth dimension in out of body mode so they are not harmed?

It shouldn;t be too hard to make a four dimensional space, but is it hazardouse? Maybe try with a mouse first?

What have you got against mice?

[Philitas]

Utter nonsense. What a waste of a perfectly good mouse.

I don't understand exactly what you're going on about. Correct me if I'm wrong, but the fourth dimension (and any dimension that may exist after it) isn't something that can be visualized. It can only be represented mathematically. As far as we're able to claim with any sufficient degree of certainty, there are definitely at least four dimensions. The first three are obvious, i.e. what comprise the world we see and give it depth. The fourth dimension, then, must be time.

Arguing for any dimensions after the first four is merely speculation (perhaps only until the LHC is back on), often just a necessary mathematical construct used to make the wilder postulations of theoretical physicists possible. For example, one physicist argued that there could indeed be as many as 11 dimensions of space, and two dimensions of time. And this apparentrly reconciles some alternate hypothesis of Super String theory with Einstein's Theory of Special Relativity. To most of us neophytes, myself included, this sounds like gibberish, with about as much superstition involved as positing the existence of a supernatural deity.

If space and time are so interwoven that we simply refer to it as space-time, then there are obviously 'dimensions' for both space and time. From what I've gathered, you're talking specifically about a 4th spatial dimension, rather than the necessary dimension of time that must accompany the first three spatial dimensions that are apodictic. You seem to think this fourth spatial dimension is just another space within the third dimension, so to speak. But that is inherently paradoxical if you think it's something that can be visualized or conceptualized.

Nice synopsis.

From what I remember from physics, that's very close to accurate. Here's what I remember, as it differs slightly from what you said, but the general idea is the same.

I was taught that the notion of the 4th dimension as time was inaccurate. The 4th dimension is spatial, as are all dimensions involved with String Theory (which requires 11 dimensions as per the new models instead of, I think, the old notion of 6). Most of the dimensions exist as almost infinitely small, coiled "string-like" structures called branes. These coil up around each other and vibrate, producing the wave functions of the particles that exist on our plane. I think it's the 5th through 11th dimensions that are so small they could never be anything like the three dimensions we enjoy.

Time, as opposed to being a dimension, is a component of the fabric of space. When space gets distorted through gravity so does time.

Three dimensional objects are incapable of experiencing anything more or less than three dimensions, so it's folly to try and move into the fourth. You can move a 2d object all you want through a 3rd dimension but it can never escape the confines of its 2 dimensions.

We were taught some multidimensional math. That was a miserable time. That's what I remember, but any of it could be wrong or out of date by now.

This part confuses me the most. You have this notion that the 4th dimension is an actual place, apart from our three dimensions, that people can go to. On the contrary. As the first and second dimensions are integrated into the third, so too is the fourth into the first, second, and third. We're already in it. It's not like what we see in Flat Land where the main character actually leaves the second dimension to visit the first, third, and fourth.

(by the way, I'm speaking of the fourth spatial dimension, and not time).

Hmmm, surely the Bible will be able to answer this?

[chrisphd]

(by the way, I'm speaking of the fourth spatial dimension, and not time).

There are only three spatial dimensions and one time dimension.

[Philitas]

There are only three spatial dimensions and one time dimension.

Actually, modern models of physics suggest 11 spacial dimensions and, if I'm not mistaken, no time dimensions. I haven't seen mentions of time-related dimensions in any of my years in physics courses.

In 1908, Hermann Minkowski presented a paper which introduced the idea of time being the fourth dimension of spacetime, which would be the basis for Einstein's theories of Special and General Relativity. This association of the fourth dimension with time rather than space has become the popular understanding of the term, even though it is applicable only to Einstein's theories of relativity. Nevertheless, mathematicians today continue to study the rich geometry of four-dimensional space regarding the fourth dimension as a spatial, and not temporal, dimension.

If anyone is interested lookup a book titled Experiments in 4 Dimensions it was published by TAB books and shows the math for 1-D through 4-D and says it is easy to adapt for higher dimensions.

Yes, it does, Aussie. Thanks for bringing it up.

A sort of polarized prism(s) view ? :-)

Hawking asserts that there are 26 dimensions and Time seems to be the key factor.
Regardless of numbers, but Homo Sappiens can percept 3D only.
There are few creatures that operate within 2D, though.
