[QUOTE=Kuro.;24502204]If you believe anime, the universe will end when some egotistical fuck with too much money toys with quantum physics and causes dimensional convergence therefore negating all existence or some crap which is exactly what evil Crispin Freeman wants because he's a selfish pussy who can't get over the fact his friends died in a car crash and somehow thinks destroying all space-time will make it all better. (It won't)[/QUOTE]
Well that was an interesting read, care to clarify for those of us who dont know who Crispin is?
If we have 10 fingers, then creatures who live in four-dimensional universes must have
[code]
5/3 = 1 2/3
5*(5/3) = 25/3
Simpler:
5*(5/3) = 25/3 = 8 1/3 or about 8.3
[/code]

[QUOTE=booster;24482861]I don't know dimesnions too well, so this might be a stupid question. But can there be living things in the dimensions above the 3rd?[/QUOTE]
well if there is another universe and it has animals then yes.

He's a voice actor that does alot of work in games and anime. He's in a whole lot of stuff despite the fact he can only really do one voice. The anime I'm referencing is Noein.
Without spoiling anything he plays both the protagonist and the antagonist.
The fourth dimension is time is it not? As our Earth ages (as everything does) it moves through time. So are we not existing in all four dimensions?
[QUOTE=thf;24493307]Yes, but we would look flat to the 4th dimensional people.[/QUOTE]
we would fuck their brains so hard, they wouldn't be able to see us from one direction :psyboom:

I guess you could say they didn't see it coming.
[QUOTE=ColdFusion;24491053]The 4th dimension can bee seen as time or another physical dimension.
What you are looking for is probably the second universe. most likely made out of anti-mater looking 100% the same as the mater universe. but anything going there will disintegrate. (mater + anti-mater = nothing)[/QUOTE]
As far as I know, Matter + Antimatter = Energy
[QUOTE=superdinoman;24478044]Time for mind fuck.
You are viewing a 4th dimensional object being represented in 3 dimensions on a 2D screen.[/QUOTE]
That isn't a 4 dimensional object, because we can't view the 4th dimension.
That is actually a shadow, of a 4 dimensional "hypercube."
The only way we can perceive the next dimension, is though it's shadows, because shadows of objects are always in the next dimension below it.
So a 1 dimensional object has no shadow, 2 dimensional has a 1 dimensional shadow, 3 dimensional is 2 dimensional, and so on and so forth.

[QUOTE=thf;24493307]Yes, but we would look flat to the 4th dimensional people.[/QUOTE]
No we wouldn't.
We would look the same.
The 4th dimension simple has 1 more axis, W.
Meaning they could see us, but we couldn't see them, or at least not all of them.
(Fixed two things I realized were incorrect)
the same way flat people just see a part of 3d people (the side currently touching flatland, or the height where it is located) we can only see the part of the 4d that is where we are.. so lets say the 4d IS time, then we can only see the point in time at which we are at, and although that makes sense, then the fact that einstain said time was relative would mess this so fucking badly.
[QUOTE=JohnnyMo1;24491896]It's difficult to say but it's obvious time works differently than the other spatial dimensions somehow.[/QUOTE]
Johnny would you mind clearing this one up for me? I was of the understanding that the only difference between a spatial and temporal dimension is our perception of it. I remember reading in a physics encyclopedia some year ago that time is warped by gravity just like space, and we've seen these effects?
Also, I read somewhere that if we ever circumnavigated the universe (that is go in the same direction for god knows how long, and eventually end up back in the same spot) what would that mean in terms of dimensions?
just as you are able to create the illusion of a 3d object on a 2d surface i would imagine you could do the same with 4d on a 3d object

Read my post, it explains pretty much this.
I can just imagine it now, a 4th dimensional being explaining how a third dimensional being would experience reality and the complications of 4th dimensional objects interacting with stuff in the 3rd dimension. And then the person would go onto explain that a 3rd dimensional being wouldn't be able to imagine the world that they live in, just as they can't imagine what the 5th dimension would look like.
[QUOTE=Rastadogg5;24507604]No we wouldn't.
We would look very odd, but not flat.
The 4th dimension simple has 2 more axis, V and W.
Meaning they could see us, but we couldn't see them, or at least not all of them.[/QUOTE]
I don't know if we'd look odd because I'd assume a 4th dimensional being would be aware of what objects look like in 3 dimensions. Just as an example, 2D is very common for us to look at and it doesn't look odd. I think that as we go up and up in the dimensions that the beings could still be able to grasp hold of the smaller dimensions such as the first, second, and third, especially since it is a big part of physics.
Also, why would it be two additional axises, that doesn't make any sense to me. Maybe I'm understanding this wrong.

No, it isn't. Learn about spacetime.
[QUOTE=CommunistCookie;24507361]As far as I know, Matter + Antimatter = Energy[/QUOTE]
Matter + Antimatter = destruction
[QUOTE=Mindtwistah;24509173]No, it isn't. Learn about spacetime.[/QUOTE]
what about spacetime

You are in 4D right now, you just can't see or feel it since you live in 3D.

[QUOTE=Tetracycline;24509249]Matter + Antimatter = destruction[/QUOTE]
Matter + Antimatter = Annihilation
Annihilation = Matter and antimatter decay into high powered photons.
Guess what light is? Photons.

I was trapped in a 4-dimensional cube once and one of those started flying around the room
Oh wait that was just a movie
ah fuck, i shouldn't have read this thread so early in the morn.
the hypercube and other polytopes(? just mindlessly saying words right now) became so much less mindfucking after the Carl Sagan video. once i found out that the 3D representations are just shadows, it occurred to me that i couldn't possibly understand the objects themselves, and so gave up trying.
this thread made me switch back to ubuntu's 'polytopes' screensaver.
[QUOTE=Detective P;24499104]From what I understand, it is. As me move through the space-time of the fourth dimension, to us it seems as though we are moving forward through time. Our movement through the fourth dimension is what we interpret as time.[/QUOTE]
But that's a movement outside of time, which is not possible

[QUOTE=sbradford26;24502067]We would look 3d. But I get what you mean.[/QUOTE]
They would probably call us "flat"

But flat is 2 dimensional but 3d would be close to the same thing as flat to us.
[QUOTE=sbradford26;24516099]But flat is 2 dimensional but 3d would be close to the same thing as flat to us.[/QUOTE]
Yeah and I guess they wouldn't see 2d stuff at all like we don't see 1d stuff :v:
I know I'll probably get boxes but can some put the 4th dimension into laymans terms for me?

How is movement through time/spacetime movement outside of time?
From what I understand, time to us is simply our movement along a fourth dimension through four dimensional spacetime. While there is a forward and back along a fourth dimension, we only go forward from our viewpoint, and hence we can only see it limited, similar to how Sagan explained that a 2dimensional flatlander can only see small sections/slices of a 3dimensional object at a time, we can only see slices of 4dimensional spacetime at a time.
It's like if we were flatlanders, and only had two dimensions- length and width, and the concept of height was not fully understandable, if the entirety of our 2d spacetime were to move in 3d spacetime along a third dimension, say 'up', then we would realize when we passed certain points in 3d spacetime that we passed them- similar to how when we move along a fourth dimension, we pass points in 4d spacetime which we interpret as moving forward through time.
Least that's how I've always been taught it.
I doubt there's a 4th dimension, although it's interesting I think it's just one of those things that are perhaps plausible but in the end an idea created by humans. After all, there is no world that is 2D.

There can be no motion without time. You need a [i]Δt[/i] for [i]Δx/Δt[/i]
The derivative of time with respect to time is meaningless. Therefore there can be no motion in the temporal dimension.

Also, this thread makes my head hurt but I completely understand what everyone is saying. It's just one of those days I guess.
[editline]12:15PM[/editline]
But I'm still confused by the video about the dimensions after the 4th.
