Have any of you thought that there is a fourth dimension or tried to imagine what a 4d object looks like? anyway, i've been doing research on the fourth dimension, and i think that it is awesome and mind boogling, but doesn't exist. However, my uncle has a theory that the universe is actually in a torus (donut) shaped object that is rotating around in the fourth dimension. Basically, he is saying that if you go far enough out into space, you will end up back at earth. Here are some awesome links i found on the topic:
http://en.wikipedia.org/wiki/Fourth_dimension (http://en.wikipedia.org/wiki/Fourth_dimension)
http://eusebeia.dyndns.org/4d/vis/vis.html (http://eusebeia.dyndns.org/4d/vis/vis.html)
Please post any thoughts that you have on this subject, because i'm very curious what you think about it. Enjoy!
first, my views on the universe. like your uncle, i believe that the universe that we live in is donut-shaped and that it is floating in the fourth dimension. however, there are also other universes floating in the fourth dimension and really we live in a multiverse.

i'll type the rest tomorrow because it's late and i'm tired.
...my brain hurts.
More than 3-dimensional stuff creeps me out.
Awesome though, nonetheless.
My teacher is going to teach us about 1-10D
I've researched it in the past, too, but my brains just aren't capable of understanding it. =')
Isn't time considered the 4th dimension?
that's what i thought it was...

or do you mean "brain's"?
Even though the 4th dimension is considered to be time in physics, i'm talking about a 4th spacial dimension. I also read about the superstring theory, which is only plausable if there are 10 dimensions, with 6 of them wrapped up in the sub-atomic level. People also have theory's that state that other dimensions besides our 3 could be used for time travel. I've also read that all invisible forces like gravity and particles originate in the 4th dimension. Finally, in reply to what razer said, even though i don't believe in that "donut" theory, if it was true, then theoretically, our "donut universe" could be the necklace or painting for a 4th dimensional creature/human. Just some things to think about. And if you read through all of the articles from the second link on my first post, you will get a much better understanding of the 4th dimension. It really helped me to comprehend the 4th dimension much better, and now I can actually think about what the 4th dimension would be like without straining my brain so much!
yes. apparently gravity is a very weak force in our universe compared to other forces, so it was theorized that gravity originates in the 4th dimension (where it is very strong) and leaks over into our universe which is floating in the 4th dimension. as a result only portions of gravity are being absorbed by our universe (like when you put a sponge in a bucket of water, it soaks up all the water it can hold, but if you measure to see how much water is in the sponge compared to how much water is still in the bucket, the water in the sponge is much, much less than the amount of water in the bucket) and thus gravity is much weaker in our universe than in the 4th dimension.
my friend and i had a theory that if we can "fold" up part of the universe (the 4-d part) we can travel through as if the distace has been halved or even reduced 99%
but i forgot almost every single thing we talked about...
since our shadows are 2 dimensional, im assuming we are the shadows of a 4th dimensional world
the hypercube is an excellent example of a 4-d shape

what you're talking about is called a wormhole. wormholes do exactly that. (in theory, of course.)
i thought wormholes were something differnt.... :-[
well it looks like i have to reresearch this topic!
dang it i should have done this for my project!

lol. anyway, i'm just kind of a nerd and i watch shows about all this stuff on the science channel, so it's not like you're stupid or anything. and yeah, this would've made a good project.
im a nerd too
lol
Science channel rocks
Discovery is better though :D
Well.. I see no reason a 4th (or more) special dimension can't exist.
Imagine living in a two-dimensional universe. X and Y. No Z. Now, you're walking along your two-dimensional sidewalk, and suddenly someone from the three-dimensional world tears a whole in the piece of paper-like universe you're living in. You fall through the hole, and immediately the fabric of space rearranges you, stretching and squishing, making you another ordinary 3-dimensional shape. (yes, you probably died the transformation from 2D to 3D. :()
NOW. Imagine YOU are walking down the street, and someone from the 4th dimension tears a hole in the puny little cube you're living in. You fall through the hole... and die. However, in the 4D world, you are officially a 4-dimensional shape.
Now, the way I see it, is to get to the second dimension, you have to go THROUGH space.... between matter. Now, we can't necessarily do that, as we'd be creating a singularity. To get to the 4th dimension, you'd have to do the opposite: Not go between space, but go... through space. Instead of squishing between infinitely small particles of nothing, you'd have infinitely large particles squish through you, shoving you out, and reassembling you. Now, that's just my theory, and yes, you'd die... but hey, that's life. :P
So no, it would be impossible to hold a truly 4-dimensional cube in your hand, as the moment it enters our dimension, it would immediately be rerendered as a 3D cube. Does that make sense?
Plus, we don't have the means to get to our lower dimensions, so the greater ones shouldn't have means to get to us. However, the idea of gravity (I've heard it was in the 5th dimension, though...) and time (4th dimension) being so powerful, they leak into (between infinity: remember!) our dimension... that's quite a possibility. It would make sense, too: Gravity affects time AND us, time affects us. Does time affect how heavy something is? Nope.
Adding to that, light is in our dimension, and is probably the most powerful force that belongs in it. (Lightspeed!) Thus Einstein's belief it is impossible to go faster than light.... if we were to go faster, we'd probably tear a little hole in our universe. :'(
And that's my story. ^_^
EDIT - Actually, instead of light being the more powerful forces in our universe, Electromagnetism, the Strong, and the Weak Nuclear Forces, would be the 3rd Dimension's, "biggies".
1st Dimension - ???
2nd Dimension - ???
3rd Dimension - Electromagnetism, Strong Nuclear Forces, Weak Nuclear Forces
4th Dimension - Time
5th Dimension - Gravity
if we were to go faster than light speed, we would enter the next higher dimension (and yeah i knew the whole gravity is 5 and light is 4 thing, i just forgot :P) because we would have used more energy than is available in ours. then if we break the speed of gravity, we would go to Dimension 5, and so on.
to get to a lower dimension we would have to give up energy somehow, and because energy cannot be created or destroyed, this seems impossible. the simple way around this is that if we go to a lower dimension (this also works for going to a higher one, just conversely) we have to switch spaces with energy from the lower dimension. if we go through some space/time portal to Dimension 2, then we would leave some of our excess energy (because as stated in the first paragraph, there is more available energy the higher you go up in the dimensions) and the energy we would be adding is sent from D2 to D3 (like water displacement, jump in a bathtub thats full to the brim with water and some will leak over the sides). this would mean that if we went to D2 then some of D2's energy would have to be converted into one of D3's main energies (like what Dekudude said).
so, if we were to throw an apple into one of these portals (an artificial one, or possibly a wormhole or black hole) we might see a flash of lightning (electromagnetism) or a small nuclear blast (strong/weak nuclear forces) come back out of our end as the energy was displaced from D2 back into D3. in D2, a smaller apple (because if the loss of energy) or a rotten apple (again, loss of energy) might appear. or possibly they would just see a flash of whatever energy is the dominant form in D2. if we went up to D4, then more gravity would enter this dimension, but there would be no need for the apple to lose energy because there is more available energy in D4; in fact the apple might expand.
so yes, there is really no reason why more dimensions could exist, and no reason why we can't travel to them (we might die, but we would still arrive there. our corpses at least...).
Would it be possible that a black hole's singularity would have enough gravity to tear a hole in space, opening up another dimension? We couldn't get there, but just a thought..

possibly, singularities might have enough energy to be portals to various other dimensions.
Actually there are theories of 10 dimensions. With the continuity of things we could have an infinite number of dimensions, but our mind isn't advanced enough to possibly imagine anything past the 10th dimension.

Wait....how do you tear a hole in nothing? :P
Nothing? It'd be tearing a whole in the fabric of space and time. :P

actually, that made complete sense to me.
And also, if you went at the speed of light for at least a few decades in space, when/if you got back to earth, you would be younger than everyone who was originally your same age because as you reach the speed of light, time slows down. This, along with razors ides, makes the idea of the 4th dimension being time perfect sense, because you would start to enter the "time dimension", so time wouldn't act the same.
you know
we should gather all our ideas as a report or presentation and send it to some science institution or labs or even NASA!
they would laugh at us.

i'm not commie dammit!
In my geometry class, we think that the 4th dimension is a sponge cylinder... lol (true story). Anyway, i don't think anybody in any high position would even bother with our ideas. Plus, when do you honestly think that we would be able to travel at the speed of light to see if there really is a 4th dimension
i said it was possible, not plausible.
The look will probably stop my brain and make it blow up. 3 dimension already makes me quesy, i try not to go any more than that. :o

Damnit. We can't even see the 4th dimension of objects. Our minds are incapable of perceiving anything outside of the 3 dimensional structures that it is made out of.
