| 1d, 2d, 3d, but how do you think the 4d would be?
Posted: 9/1/2009 2:17:34 PM | I have a theory on the forth dimension...
In the first dimention there is only one .
In the second dimention there is lenth and width.
In the third dimension there is length, width and height.
In the forth ???
Imagine if you lived in the second dimension you would be flat and would not be able to see the 3rd dimension true? You would only know left and right, forward and backwards but up and down wouldn't exsit.
So living in our 3rd dimension we can move fowards and backwards left and right and we know there is down and up.
So my theory is the forth dimension is the dimension we go to when we die, as we know we all have souls its the blueprint of our character, so in the forth dimension you would be able to MOVE forwards, backwards, left, right up and down! however we wouldn't know what the forth dimension looks like because we can't see it because we live in the 3rd dimension.
What are your views ? Does it sound like a possible theory? (yes im high) | |

Posted: 9/1/2009 2:27:13 PM | | Great, so if the forth dimension is time then that would mean you would see your birth and death? and it would be possible to go back in time and forward in time? amazing... | |

Posted: 9/1/2009 2:38:46 PM | No, Time is not a Spacial Dimension. It flows in one way, and we currently don't have much evidence that suggests we could go backwards in time.
1D = Left and Right, there is no other way.
2D = Left, Right, Up and Down, there is no other way
3D = Left, Right, Up, Down, and Depth, there is no other way
4D = Time, not a spacial dimension. Flows forward only
5D = ? Good luck imagining that. | |

Posted: 9/1/2009 2:52:07 PM | If that is true maybe the 5th dimention is a collection of information what an object does in it's lifetime therefor you'd be able to go back to a point in that objects time using the 4th dimension.
If I had an apple and the forth dimension is time and time only flows forward the apple will eventually rot and disentergrate so it could be possible the 5th dimension would be all points of the apples exsistance which you could go back to when the apple was fresh making past and present and future possible.
Does that make any sense? | |

Posted: 9/1/2009 2:55:34 PM | | A dimension is not somewhere you occupy, it is a property of something. Length is a property but you can't go inside length. Add breadth and width, you have two more dimensions, which are properties of space, which is what you occupy, but space is not itself a dimension. You could keep adding as many dimensions as you like and you would still be here with them. You would just have more dimensions to trip over. Eternity is the name given to somewhere there is no time. It means timeless, or, without time. That's hard to get except as an idea because for you to be someplace without time, you couldn't be there long enough to notice. Perception requires time. | |

Posted: 9/1/2009 3:24:15 PM | Haven't you answered your own question here
Imagine if you lived in the second dimension you would be flat and would not be able to see the 3rd dimension true? You would only know left and right, forward and backwards but up and down wouldn't exsit.
As a 2D object would be baffled by any explanation of 'up or down' so would any explanation of 4D be to us 3D objects. So even if I did have the answer I wouldn't be able to explain it to you in any reference that you could understand. | |

Posted: 9/1/2009 3:31:44 PM | | Given the nature of discovery, one of the best ways to do it is to wonder why and talk about things you don't understand. That's how it's done. If people stuck to what they already knew and what was known generally, there could be no new and better ideas. In asking the questions, trying out new explanations, you create new knowledge by stumbling on what nobody has yet found. | |

Posted: 9/1/2009 3:49:22 PM | The easiest way to think of a dimension is thinking of the Cartesian plane in mathematics. At one dimension you just have a point. At 2 we have the classic (x,y) coordinate plane. At 3 we have (x,y,z) coordinate plane. At 4 I guess you could say we have (x,y,z,) and the movement of x,y,z through the plane t (time). The co-ordinates x, y, and z describe space, they are spatial dimensions. If you've ever done the equation of a line or calculus you will find out that a point can sometimes move along a path. That path in the fourth dimension can be described by time.
Its important to note two things. Firstly while we opperate in a 3 dimentional space and are completely aware of it. However we are not completely aware of the fourth dimension time. We are only aware of it at subjective moments. One comment from a person was that
"If we were completely awaree of the 4th dimeantion then we would seem like a long undulating snake"
However we don't. We don't see ourselves from brith to death but at certain moments along the progression through the fourth dimension time.
To see ourselves in the 5th dimension we would have to have a new definable axis that we are aware of. Once we have that we can calculate the location and movement of a point in the dimension. String theory is famous for theorizing higher dimensions.
Lastly dimensions are very important in physics and is often showed through vectors. For instance 14 km/h is a vector and km and h can be thought of as dimensions. We have km which is the speed at which the point moves. Then we have time which is the speed at a certain point in time to give us the rate 14 km/h. It is a linear equation and it shows that the point has the form y=mx+b. m in the equation doesn't change. It is a set variable (unlike calculus that describes the rate of change). Therefore we can say y is to kilometers as x is to time. If m is an unchanging quantity (this would be 14 since the point progresses linearly through the Cartesian plane). We therefore have the equation km=14(time). When time = 1 hour km= 14. When time = 2 hours km = 28 and so on.
It is in this very basic way the evaluation of higher dimensions is done. Its just that very complicated methods (at and beyond the level of calculus III) are often used. Also we can even have half a dimension (fractals and the like). It can get very complicated and mind boggling from there. It may not be possible to imagine the 5th dimension however we can toy with the idea through mathematics.

Posted: 9/1/2009 3:56:00 PM | This thread is thinly veiled religious confirmation.
In reality, astrophysics and mathematics tell us that there ARE other spacial dimensions...as many as 11 according to superstring, or M, theory. And this fact is gotten to by using the math and physics, NOT by pure conjecture. According to the math, it is likely that other spacial deminsions exist, but are too small to affect us. Of course, this has not been proven yet. Not dont make the mistake of equating the math with pure conjecture.
Here is an example of pure conjecture: The 5th dimension is The Land Of Dairyqueen.
Another example is the original post of this thread.

Not to sure where you're comming from here but no one has yet said that a 4th dimension does not exist. What we ARE trying to do is explain what one would look like. | |

unfortunately this can not be done by imagination. It can only be done thru mathematics. A three dimensional brain can not think of the 4th spacial dimension any more than a 2 dimensional flatlander can imagine the 3rd. This was well illustrated in the book Flatland by Edwin Abbot.
Higher dimensions can only be grasped thru the math that explains or predicts them. This is a limitation of our brains. No astrophysicist can "picture" as a reality, the fourth spacial dimension. But mathematically, they can understand them well.

Posted: 9/1/2009 4:36:22 PM | yes, you did. So unless we start using the advanced math of astrophysics in this thread, there is no point in trying to explain what the next dimension looks like. And I dont know the math well enough to bring it here.  | |

Posted: 9/1/2009 4:45:23 PM | | this is where someone jumps in and writes fancy symbols and uses their O so powerful brain to enlighten all of us...awkward silence...yeah I'll stick to the conjecture thingy. The 4th dimension is a rabbit playing ping pong on the back of a angry turtle and the 5th dimension is superman destroying the universe by accidentally farting. There...we know what the 4th and 5th dimensions look like. | |

there is a certain personality that just can not describe things on a visceral level. If you cant understand the basis of someone's post, then there is likely nothing to understand. A famous person once said, "if you cant explain what you mean to a 12 year old, then you dont know what you mean"
The funnier thing was, alot of his math wasnt right either. | |

Posted: 9/1/2009 5:31:35 PM | Well just out of speculation, does anyone have any ideas on how another dimension could possibly behave? The ones we know appear to build on one another. I just don't have a clue how the next step up could go.
You have length, then add another line and you have width, now add a third line for depth, and that's 3 dimensions built on one another. The next one is Time, which pretty much gives things the ability to move and change from point to point within the 3 dimensions.
try to make the speculation at least somewhat realistic.
Maybe the 5th dimension is a branch off from Time, showing all possible outcomes or directions that time can go (based on choices/how things work out, etc..). I really can't imagine how a 4th Spacial Dimension could go, since we can already seemingly move in all directions, where else is there to go? Of course I'm sure a "flat lander' would say the same thing if he can only perceive left and right, and has the ability to move both left or right -- where else is there for him to go? | |

Its unlikely to be time as time is a function of 2 & 3 dimensions. Look at a computer, that is strictly 2D, on/off...1 and 0, but in order for it to work there has to be a time element, we call it clocking speed.
Time is more like the 1st dimension where it only has 1 direction, forward, and that can be varied (dilated) with relation to its energy
More likely to be energy or gravity, energy is what makes up matter. I'm just quessing now. I doubt that it is anything tangible. | |

Posted: 9/1/2009 6:58:03 PM | | I am disappointed in this thread. Naturally, the most stringent requirement of a viable string theory of the Universe is that eventually the theory has to make contact with the 4-dimensional space-time in which we appear to live. This passage from 26 dimensions to 4 dimensions occurs in two steps in heterotic string theory. First of all, 16 of the original 26 dimensions must compact, or curl up on themselves, in a very nice self-consistent way; and then 6 of the remaining 10 dimensions must compact nicely as well in order to get down to our apparent 4-dimensional observed universe. | |

Posted: 9/1/2009 7:08:26 PM | 26 dimensions?
I thought String Theory theorized 11 dimensions, but then again I'm not too up to date on that. As for dimensions curling up on themselves or being compacted to very small scales, I'm not even sure how that works, it seems to defy logic.
Do they know what kind of dimensions they are? Spacial/Temporal/ some other unknown kind. | |
