Dimensions

[SnWRifleman]

Does anyone have a complete list of all the dimensions that are known so far? I know like 1-D, flat shapes, shapes with volumes, and blah then there are the weird ones like the Twilight Dimension and black holes that can alter dimensions or whatever.

 

 

 

Links are nice too :P

 

 

 

Just some info on object dimensions I looked up-

 

 

 

1-D: Basically a line. An example would be like a straight line....(DUH!)

 

 

 

2-D: Your basic plane figures such as squares, rectangles, and such.

 

 

 

3-D: Your shapes that have volume, such as cubes. An example, would be a box.

 

 

 

4-D: Shapes within shapes, I'm guessing. I'm not too familiar with these dimensions past 3-D. An example would be a tesseract, which is kind of a box, without the squares as the sides. It connects to a middle square inside the outer square.

 

 

 

5-D: This consists of, not like the fourth dimension, not only 2 shapes connected, but many different shapes. In physics, this is a hypothetical dimension used in the Kaluza-Klein theory used a fifth dimension to unify gravity with the electromagnetic force, and now is seen as essentially a gauge theory with gauge group the circle group.

 

An example of this would be a penteract

 

 

 

I don't know about other dimensions.

this video greatly explains the first through tenth dimensions.

 

 

 

edit: warning - this video has been reported to contain inaccuracies. remember that the dimensions explained here are only theoretical.

that video is amazing, even though I'm struggling to understand anything above the 4th dimension.

 

I kind of worked out that each dimension is a line between 2 points (which are the previous dimension), and then a line from that line to another point (the previous dimension) to create the next dimension. the cycle then starts again, 2 points (the previous dimension) with a line between them.

 

 

 

its really hard to explain and that video does an amazing job of it.

[oegly41]

Yes, that video is marvellous! But that video talks about the forth dimension as time, not a space dimension. He is basically saying that tesseracts don't exist. The forth space dimension is very hard for us to imagine, as it could almost be explained as invisible pockets everywhere. A forth dimensional creature could be able to take the content of your stomach without harming you.

 

 

 

[hide=Tesseract]

 

 

* 1-dimensional: Two points A and B can be connected to a line, giving a new line AB.

 

* 2-dimensional: Two parallel lines AB and CD can be connected to become a square, with the corners marked as ABCD.

 

* 3-dimensional: Two parallel squares ABCD and EFGH can be connected to become a cube, with the corners marked as ABCDEFGH.

 

* 4-dimensional: Two parallel cubes ABCDEFGH and IJKLMNOP can be connected to become a hypercube, with the corners marked as ABCDEFGHIJKLMNOP.

Jeez, watching that shape animation thing is addicting, haha.

 

I've always wondered what the 4th dimension would be like, but thats pretty dang complicated.

 

 

 

(For me anyway, I'm pretty terrible with shapes and dimensions, haha)

So a Tesseract is basically space inside of space? If we can figure out a way to use that to effect, then we won't have to worry about limited space, especially if one spot can hold more than one "space". What I've always understood a Tesseract to be (functionally, a wormhole that you can direct where to open) seems to be wrong. Meh, I don't mind. This way can be better, really. We need to develop tech towards this, imo. However, I'm sure all of us saw The Mist. Don't want that sort of situation. :? :ohnoes:

anybody ever see the movie cube? man that was awesome.

[warren211]

Disney and other amusement parks seem to be convinced that 4-D is like a 3-D movie except you can smell and feel things liker water spraying and stuff... I'm having trouble understanding dementions beyond 3rd, although the teserract looks freaking awesome.

[assassin_696]

Just a heads up, that video seems to explain things beautifully at a superificial level, but it's not really based on any kind of science or mathematics. It's just some aesthetically pleasing speculation on behalf of the author. Don't make the mistake of thinking that's how string theorists conceptualise 10/11 dimensions, because they don't even try, it's impossible.

 

 

 

(Surprised I beat Reb to it :P )

 

 

 

I bought the book, because I am a graduate student in string theory and was curious about "new" ways of thinking in ten dimensions. I knew the author of the book was actually a musician (some research with google was required for that), but so is Brian May of Queen, and his book "BANG - THE COMPLETE HISTORY OF THE UNIVERSE" is very well-written. Well, I couldn't be more wrong. Whereas Brian May studied physics (and is currently doing his long-lost PhD), Bryanton has never touched a scientific article, let alone stood near the mathematics required to grasp them. All his "knowledge" comes from science fiction (which he uses as genuine "references" for his wild ideas), popular science books (Greene, Kaku and Randall) and Scientific American.

 

 

 

Although the book is not intended to be a discription of "real physics", as he points out in the introduction, his ideas on ten dimensions and the alledged connection to string theory and the many worlds interpretation of quantum mechanics couldn't be stated more explicitely and couldn't be more wrong. The many world interpretation 'assumes' multiple universes in which all possible quantum processes do happen. Bryanton thinks these multiverses are in the dimensions 5 to 10. Moreover, our third spatial dimension is merely the thing "we fold through" to go from one place on a surface to another, which are not directly linked. If he is referring to the holographic principle, he's wrong there as well. Physically and mathematically, what he claims about space and time is absolute bullocks, if I may use the expression. The first chapter is exactly what is shown on his website and the rest is just a filler in which he tries to explain the ideas of quantum observation and its relation to philosophy, poorly. There is absolutely no (scientific) connection to string theory or whatsoever, except that the number 10 and the word dimensions are in the same sentence. The eleven dimensions of M-theory are in his view superfluous.

 

 

 

The book is perhaps intended to be scientifically and philosophically provocative, but in fact it is scientifically incorrect and at most philosophically boring. If you really want to know something about string theory and modern developments on a non-technical level, buy The Elegant Universe or The Fabric of the Cosmos by Brian Greene, Hyperspace or Parallel Universes by Michio Kaku, or Warped Passages by Lisa Randall, and your money will be well-spent. Other ideas on quantum gravity can be found in Lee Smolin's "Three Roads to Quantum Gravity". For the mathematical inclined reader (as Greene would call it in the notes), Penrose's "The Road to Reality" could be interesting, which is a brilliant mathematical exposé of theoretical physics.

 

 

 

Moreover, because the author does not fully understand quantum physics, his explanations are even for scientists hard to follow, because they don't seem logical. For non-scientists, I cannot recommend this book either, since I don't think it will help you in any way: you probably won't understand the science and if you do understand what the author says, you understand the wrong thing.

[bleep]. Yes, you did beat me to it. In fact, I saw the title, thought, "yes, someone's going to post that and I can do some bashing!", came in, saw the vid posted in like the third post, felt great joy, then saw your post, and suddenly became depressed for losing out. Good job.

[Cyco_Reborn]

Yes, it was awesome and the hypercube one explains 4d shapes reasonably well!!!

[mrpez]

the video is just theory. no one said it was actuality.

[Rebdragon]

The very fact that you posted it showed that you believed it had some credibility, where none existed. You're not stupid for it, you just didn't make sure it had good credentials before wholeheartedly accepting it.

 

 

 

Now that you know, never post that again, and spread the word to others to never post it. It is a malevolent cancer on the already weak-minds of internet geeks.

[Jaziek]

the video is interesting the first time you see something like it, but they become boring the more samey lolpseudoscience videos you see.

[Dizzle229]

this video greatly explains the first through tenth dimensions.

 

 

 

 

 

 

 

 

Lol, I could only understand the first through fifth dimmensions.

[SnWRifleman]

If any of you guys have seen the show Jimmy Neutron: Boy Genious, he keeps a "hypercube", AKA a tesseract, which can hold more than it's volume. So basically, a 3 dimensional object, would be flat to a 4th dimensonal, I think. Also, in Fairly Odd Parents, Timmy's Godparents have that castle in their fishbowl which can store more than it's volume. Just a few examples.

This video was rather interesting but made my head hurt :wall: at some points, like the multiple infinities and universes (multiverse?)

[bleep] you, science!

[Randox]

It should be immpossible for us to concive the workings of any higher physical dimmesnsion then the 3rd (except mathmaticly on paper) simply because our brain works using only 3. Its just like trying to immagine what an infrared or ultraviolet colour would look like, or any other part of the EM range other than that we can see. The brain can't just make up a new colour that has never been precived before. For all our creativity, there are definatly limmits. One example of something that you have never experianced but can immage is 360 degree vision. Its pretty chalenging when awake and I doubt many people can concentrate hard enough for long enough to do it, but while lucid dreaming it is possible to do. The reason this works where new colours and physical dimensions work I immagne would be because 360 vision is merly an expansion of vision, so we have some point to work from.

I remember seeing that video about string theory and the ten (current) dimensions. Interesting stuff, and not too hard to understand. It makes pretty much sense, to be honest.. Until something better comes along.

If you've got any suggestions, I would be happy to hear them. Preferably something I could download or buy for a fairly low price.. I don't have as much time as I would like to spend on things like this, due to real life responsibilities. :|

 

 

 

 

 

(And I do realize that the video is really not very accurate or in depth, but even so, it is interesting to watch.)

[Lenticular_J]

You guys should read the Cantos by Dan Simmons; four great sci-fi books. They aren't exactly the most realistic takes on physics and the like, but some very interesting, if deep, views about the dimensions of the world. It's really hard to truly grasp the series, though - tons of symbolism and references to John Keats (in particular; other authors and poets did show up), who I think was a very, very difficult poet to read.

The entire explanation of at least half the levels of wrongness of that video are all in assassin's post. Read and stop spreading the cancer that is that piece of crap of a video.
