the 4th dimension is that eerie glow from behind my wardrobe!

Haven't 'they' also made an electron 'move' faster than light using quantum tunnelling?

Number 19 is earwax. Just mine though - I have my own personal dimension.

Tunneling? "Worm Holes"? Yet another speculation. Yes, theres warped space, but a hole to travel from one warped point to another? Hmm...
Posted: 23rd Feb 2003 16:27
but for something to travell faster than the speed of light the above equation theorises that the electron would have a negatuve mass :S (which is physically impossible). Quantum tunneling? ooooh sounds star trekky (as with a lot of quantum physics!) my physics teacher could be a valuable resource?? (the above equation is also wrong sorry!
it should be:
M = m/(1-(V^2/C^2)) If V > 2*10^8 (Spd of Light [c]) then M = negative.
And what the hell has this got to do with the 4th dimesion?. May i also add that the glow behind my wordrobe is now getting brighter!!!!

Greetings,

First, let me say that dimensions are for forming frames of reference (directionality in some sense). The dimensions do not have to be orthogonal (meet at right angles), be straight, or even be constant. A 3D curve can be represented parametrically at functions x(t), y(t), and z(t), where t is a straight constant dimension, but x, y, and z are not.

When talking about the "real" world, the first 3 dimensions do not have to be spatial, and the 4th doesn't have to be temporal. My doctoral thesis was on a 6-dimensional representation for light filling a space. This is a real representation called the plenoptic function. The first 3 dimensions were the position of a viewer. The next two dimensions represented the direction that the viewer was gazing. The last dimension represented time. The domain of the function was (space, direction and time), and the range was incident light. So I should know that you can MAKE UP any dimensions you want.

As for Einstein, relativity, and other interesting stuff, look at "Faster Than the Speed of Light: The Story of a Scientific Speculation by Joao Magueijo." It is interesting in that it expands Einstein's ideas quite nicely, in some sense mapping Einstein's theories as functions of "universe time."

I more layman terms, the book contains very interesting info on Lorentz Transforms and the speed of light. The basic idea is that light does have a constant speed at each instant in the existance of our universe. So the constant c is actually replaced by a function c(t), where t varies ever so slowly through the lifetime of the universe. Very cool theory with huge ramifications.

I have my fireproof suit on, so let me have it!

Best,
Jeff

Wow! This post really is dragging on.

If c is a function of (c(t)) t decreases as c increases, this means for time to stop, you would have to have an infinite speed, or to c = 0 then time would have to be at an infinite rate. If you could reach an infinite speed, you would be everywhere at once (aparantly transwarp in star trek!!). Also space could be the 4th dimension. As space can be altered in the way dimesions can be. (Quantum tunnelling?) Wormholes/black holes also explain the 4th dimesion as space is bent/warped here. Quantum slipstream drives (star trek again!) would just be an expansion of quantum tunnelling. This can explain alot about the 4th dimesion..... and could also get me yelled at in this thread! Question, how many people have heard of the Atari Jaguar? (sorry, have to break this curse!!)

OK.. it's my turn:

1) go to this address http://dogfeathers.com/java/hyprcube.html

2) go to the cinema to see The Cube 2 - HyperCube

the life seems meaningless.. :-p

I never said that c(t) is a (monotonically) increasing function. I just said that c has a value that is dependent on universe characteristics that can be encapsulated in a t (time) parameter that describes the state of the universe. t is not necessarily the wall-clock time we are used to.

Maybe c(U(ut)) where U is a function that describes the state of the universe and ut is a parameter that fixes the universe time would have been a better simplification .

Best,
Jeff

I think the best way to explain time is:

Imagine a monorail traveling in a straight line for infinity.


The monorail has one coach travelling in one direction at a Const speed.....


We and the universe are on that coach on a one way ticket to infinty.

"WHY would time be the 4th?"

it has a lot to do with geometry, actually. you see, you can always check a point on a 2d plot of points to see if anything exists on it. This is done by looking at x,y. Similar are things on a 3d plot, instead though it is x,y,z. In a 4th dimentional plot, you look at x,y,z, and the time. The x,y, and z change as time changes. It makes logical sense..."the 4th dimension can be time or another spatial one" it is both at the same time, there is no "or."

and please, for the love of god, NOBODY ON HERE TALK ABOUT ANTIMATTER!! it is VERY unlikely that anyone will actually know anything about it besides the fact that its crazy and strange and being made in small amounts in labs.... dont drag it into our debate if its going to just confuse people...

btw, i like this topic, finally people to talk to about physics

1d is a single point it can't be place on any axis it just is.
2d is a 1d point or points position on 2 axis
3d is a 1d point or points position on 3 axis
a 4d picture is a 3d image compiled over a set time period. like a spear moving in a circlar path the 4d picture to show this is a torus, a intertub shape for those who don't know what a torus is.
the 4d axis is a time refrence a set period over which movement occurs.

"enculer" is the verb... "enculé" is the right word...

Well u obviously dont know how they r used then coz it was this french girl that typed it so...be quiet

.............Why don't you all make another topic but still about this... THIS TOPIC ALREADY GOT 130+ MESSAGES!!!!

whats the point?

I just spent 20 minutes reading this thread and I have to say its interesting.

All I gotta say is.. the 4th dimension is time! I stand by eintsien's theories.

Its all about world lines.
Posted: 17th Apr 2003 7:14
time a 4th deminsion-no time is merely a measurement term
motion a 4th deminsion-no then wouldnt we already be in the 4th deminsion??
The cube thing?-maybe hard to imagine but it is the only post in this topic that kind of makes since

Time doesn't exist. It is a illusion create by owr minds. It is not a constant for it flows differently for each person, there is no true way to measure it. Time does not exist.

If all the previous dimensions deal with geometry, WHY would time be the 4th?" why you ask....because thats the way its been for about 80 years since we've had the Theory of Relativity
Siecentics thought that our solar system was only one out there, and there were no other planets for hundreds of years. Just becuase a theory has last for a while doesn't prove it's correct.

In any case how do we know that there are any dimensions, let alone three? If you rotate a 3D object 90 degetes in any direction then it is at the same axis as when it started. Everything is perspective, we have yet to gain the knowledge to grasp the fundementals of the universe. In 100 years all the theories we have to day will be disproven.

On topic, nice code but I was expecting something I saw in another program somewhere, I wish I could remember what it was called.

Whoops, I didn't see there were 2 more pages, oh well, my comments still stand true.
