1-D, 2-D, 3-D,....Fourth Physical Dimension

Im kinda continuing this from another thread which deserves a thread of its own.

well somewhat like this the people in the 2-D plane have the square like us people in the 3-D plane have the cube, so the people in the 4-D plane would have the hypercube
a square is in the 2-D plane made of lines which are from 1-D(4 lines), a cube is made of squares which are from 2-D(6 squares), so a hypercube is made of cubes which are from our plane 3-D so i assume the hypercube would be made of 8 cubes but if we were to try to create a hypercube it would be paradoxilly wrong and disfigured it would be a jumbled mess and if you tried to take a picture what it showed would be paradoxically more confusing than what you actually but on the 4-D plane all the lines would be equal and straight, like all the lines of cube are on our plane

it is so hard to imagine of what a hypercube might look like because no one has ever seen "anything" from the fourth dimension so there is not even anywhere to start imagining this shape so as far as we are concerned the 4-D universe can only be described , yet the imagination is not trapped by these dimensioanal boundaries it can imagine nearly anything so maybe one day someone will truly imagine how the fourth dimension looks like who knows what effects it may (or may not) have on the brain, i have tried to imagine this 4-D plane but every time i get something extremely confusing i couldnt begin to explain it

we define our world/universe using Lenth,Height and Depth so what would this 4th property of 4-D geometry be some extra form of depth seems like the only extra one, logically there can only be one height and lenth so there must be some kind of "deeper depth" if that makes any sense

here's a link that i found about Hypercubes to help you visualize what a hypercube might look like-- this one is better with a moving picture http://dogfeathers.com/java/hyprcube.html

we just can't imagine this...
in theory, i mean, while writing on a paper and doing calculations, you could also create a 27th dimension, but no-one can prove this because we just can't imagine it.

just to know: i've read somewhere that our eyes aren't able to see 3d, they just see everything from an advanced 2D-view.

There are many connections between the Universe that we live in and and spaces of many dimensions. In fact physicists work on a new theory that unite all basic forces (like electromagnetism and gravity) into one. Actually the idea of more dimensions helps to simplify many physical theories.
I you want to easily learn more on multidimensional spaces and their connections to our world then read the following books for example:
Brian Greene - The Elegant Universe : Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory

i have heard and read that the fourth dimension is considered time
the first three are space, 1-D, 2-D, 3-D
and since time and space are part of the same universe, so it needede to be another dimension
this is why the supercube is not really possible to put into geometry, because time cannot be seen

just what i heard and read

i do not see time as a dimension, time just happens to be and is a result of causality, everything has a reason, everything results in something else, this means everything is changing and isn't standing still like in a picture, so we got time, in fact if you believe time is a dimension you could say causality is the 4th dimension, just a thought

in reloaded the oracle said the following sentence: "You have the sight now Neo, you're looking at the world without time" Do you guys actually now what this means? A world whitout time would be a world without causality. What's a world whitout causality, a world where only choices are made? I do not understand.

It is quite possible that the 4th dimension is time - that it can be seen, and that it is imaginable.

Think about any object in relation to time. For example, if I throw a ball from me to you, this 3 dimensional object will travel a hyperbolic path. 3D is thinking of a snapshot of the ball at any given point during its travel from point A to point B. On the flip side, 4D is the 3D ball creating a 3D arc.

well this/my theory is based on the fact that time is not a dimension it is just something that happens, it is a record of change without time there is no change

this is why the supercube is not really possible to put into geometry, because time cannot be seen


the hypercube (not supercube) of course could not be put into "our" geometry its impossible only part of it would fit and like i said up above this is based on time NOT being a dimension

the forth dimension could be 'evolution' instead of 'time' because time is just an illusion, but the things we see evolving in front of our eyes are not an illusion. we may not be able to see the "4th dimension cude' because it is evolving...
dont know all that much, but i tired to contribute as best as i can

cant exaxctly see where the sides are or the inside lol
(hypercube maybe..)

I believe that...
2 dimensional figures can manipulate 1 dimensional figures
3 dimensional figures can manipulate 1 dimensional and 2 dimensional figures
and so on..

Also 2 dimensional figures can not fully comprehend 3 dimensional figures.
3 dimensional figures can not fully comprehend 4 dimensional figures.
and so on..

In the film "donnie darko" The forth Dimension is regarded to as being "metal and water" that is what it is built up of.
If you look into time travel, it is explained that the reason that time travel could become possible (obviously in many years time) is that humans would find a way to break though the metal and water barrier, thus being able to travel back and forth in time.

Its an interesting idea.

But in order to travel thru time you have to go faster than the speed of light which is impossible becuase as you get closer and closer to the speed of light your mass increases and as your mass increases you need to go faster to achieve the speed of light so its a circle, you go faster and get more massive so you then need to have more propulsion but then you get more massive and so on and so forth.

I read a similar situation in a book i read "The Cosmos" its an in-depth veiw at every aspect of human history and what we klnow of our universe and where its headed and so on, but anyway it talks of situation where a ship steadily increases to the speed of light but as it speed up it gets more mass and it ends stating that to reach the speed of light you would need an Infinite amount of energy

I just thought of something in regard to time always being a higher dimension. Its sort of paradox in a way, If there is an infinite amount of higher dimensions and time is always a higher dimension so that it "flows" through all of them. Its strange because in some ways the theory nulifies it self unless there is something higher than infinity as such. An entire zone of existence seperate from the dimensions all together, and in that way It all works out.

But then again this kind of goes against, me not counting time not being a dimension.

If you guys want to read a great story about the fourth dimension and the supercube:

Just type "--And He Built A Crooked House" in Google. It will take you to the story. Its the first or second choice.

Its by Robert Heinlein. Its a really trippy story.

Thanks NMN only read a little bit of it, but great so far :)

I always talk with my dad about this, and he always siad the 4 th one is time and so does mummy. But in hypercube the 4th one looked like it was a black hole, and time was all twisted up. in the end the cube disapered and if illusion is like when something disapers then, maybe stalin is right. I need more help though with thi.s.

HEY CONNER! :D Nice to meet you :)

I agree with you about that 'black hole'.
In the book of time travel, it was said that the 4th dimension was the product and space and mass, thus creating a never-ending 3D tube that is able to be seen, but one can not see through it, or know where it ends up.

4th Dimension is based also based alot of the theory of time travel. It was the theory, that because the 4th dimension was made up of space and mass, that is one was able to actually see this dimesion, time travel would be achieved.

I will have to do some more reading and get back to you on this one :)

Thank you so much stalin. I wish he had read your reply before he went to sleep, though he was very impressed with it all and at one stage was a bit hyper lol. I'm very proud of him, and when he does read here he soaks it up like a wee sponge. I'm quite proud of him. I have to help him type of course, though it's all his words.

(can't half tell I'm a very proud mother can you)

No, not at all, UT;)

Now, AC, nice to meet you bud. I am so happy you talk about science. It brings joy to my heart. *tear* Man that is so cooooooooool!!!!

Now enough of my geekiness. I still think you guys need to read that story i posted above. It is reallllllllllyyyyyyyy good. I guanrantee.;)

didnt really think this was "worthy" of a new thread since its for the most part about the same thing

Fragmented dimensions, dimensions where only certain things exist period. Such D would be where there is only lenth and nothing more, or there is "stuff" but no lenth or width or depth. Becuase these dimensions lack any other properties time does not quite "flow" through them as it should, there are pockets where time is hyperactive. Other zones where it moves so slowly that no obserable change could be made in millions of years.

man what a freaked out imagination I have. :PI


Welcome Conner glad to have you here :D



The Xenocidal pyscho has spoken

4-D lokks like 3-D..so isnt that 3-D???

I'll admit that a lot of this stuff I find difficult to grasp. Now that I've got that off my chest, check out the books "Flatland" and "Flatterland"- they've got some interesting ideas relating to other dimensions (primarily "Flatterland").

4-D lokks like 3-D..so isnt that 3-D???

Well the 4th physical dimension does not look like the 3rd because there is an extra geometric quadrant.

In M-Theory(Membrane) however the 4th dimension is time, so in fact we live in a 4th dimensional universe.


Thx Psp, would I be able to find these books at borders or Amazon ?

no problem :) They're fantastic books, and "Flatland" is fairly short, which adds to its appeal. "Flatterland" goes into more depth of other subjects, such as dimensions beyond 2-D and 3-D.

Buy Flatland (http://www.amazon.com/exec/obidos/ASIN/048627263X/qid=1098934142/sr=2-1/ref=pd_ka_b_2_1/002-4773036-0762463)
And here's Flatterland (http://www.amazon.com/exec/obidos/ASIN/073820675X/qid=1098934142/sr=2-3/ref=pd_ka_b_2_3/002-4773036-0762463)
