I want everyone to explain to me their understanding of the fourth dimension. Is it something we exist inside? Is time the fourth dimension? What research could be done, and what out there have you already read? Theories? I feel like everyone has a different idea of what the fourth dimension "is"..
I miss debate threads.. QQ
-
you enter the 4th dimension when asleep and its amazing and stuff.
-
Isnt 4D time?
-
The 4th dimension is time/space. It is a very confusing concept but I find it fascinating when I can understand it. The only thing that I can remember at this time is that time and space are relative. So the speed of light is the same for all observers but this is where you get into time travel. If your able to somehow go faster the the speed of light for about a year and then return to earth you would have aged 1 year while the rest of us aged 60 or 70 years. It is so much more complicated then that but that's all I got.

i don't know if this is realities and its also one of the conspiracies but apparently Albert Einstein learned how to tear into a different dimension ( possibly 4th ) where any possibility could happen but it had to be realistic. One of these was Time travel. Or some shit i could be getting the wrong any who.. The Nazi party later learned of this and put it to use.. They developed the Bell which was supposed to be a time travel device.. So on.. Shit got real.. Anyway they then tested the machine " Bell " with 4 Nazi honor guards and it did for a brief moment tear through the dimension but then it was shot back into ours and teleporting from Germany and later appearing in Roswell new mexico.. The men inside were turned inside out. This all sounds weird i know but it would be cool if it were true.

I was going to try and explain it but then I started trying to explain "gravity" and realised that most of you wouldn't understand so I'm going to give you a wiki link on Spacetime.

didnt you learn anything NEVAR TRUST TEH WIKI Meme4

The forth dimension is pretty much decided as time, so the question itself is somewhat mute.
However explaining time as a dimension would be hard as fuck, because as far as I know time is only the human perception of light (information) traveling by a speed of 3*10^8 m/s which is C in the well known Einsteins theory of relativity Eo=MC^2, and then light curves at the end of the universe.
By the way I think I should mention that Einstein is the one who started thinking if I sit on light nothing could go faster than me, considering as far as we know we would become energy/light if we did so. So that being said, don't think Einstein was much of a believer in time travel.
Oh well I didn't have physics for so long...
As for the possibility of more dimensions, there are a lot of theories that are somewhat backed by logic that basically require the existence of more dimensions. One of those would obviously be string theory.
-
What he said.
-
I can see what Jorgen said is somewhat valid, however if we are talking movie theaters here pretty soon our seats will be applied to the motion of what's on screen, and there could be more physical addons like wind/air, water, etc..
-
Well movies and cinemas are kinda different. Commercial dimensions is vastly different than those we talk about in physics, in fact you could make the argument that time goes by in a movie so every "2d" movie would be "3D" and every "3D" movie would be"4D".
Then what you are talking about would be some sort of weird hypothetical "5D", although it is more like a side effect of all the other dimensions (irl).
-
The 4th Dimension is the Dimension 3 Dimensions away from the 1st Dimension. Not related to the 4th Wall.
-
Well, what exactly IS time. For a while I was confused and believed time was simply a human creation to measure what has happened and what wll happen. Kind of like inches and pounds. Those measurements change from country to country, becoming more universal as we expand and communicate with another. Though time has always just been, we've all agreed on the same calanders and clocks. The reason I bring this up is because when one is traveling at the speed of light or just traveling in space; time is kind of different for them so to speak.
Also, if humans ever entered the fourth dimension, how would we travel, look and percieve things. I kind of always imagined it being everywhere you once were, are and will be all at once, kind of like becoming a sentient string of yourself.. but would t be a physical existence? Perhaps it's physical impossible altogether; or just inconcivable..
-
@Pillz gotta say I love when people don't read answers on their own debate thread.
Time is a human beings perception of light moving at a constant speed of C (3*10^8 m/s (meters not miles)) to all directions, eventually they get curved at the "end" of the universe.
Entering the fourth dimension is impossible to imagine, basically because it simply exists. It would be like imagining a 1 dimensional entity, how can something only travel one direction? even a line like - has 2 dimensions up/down and forward/backwards, how can something be 100% flat, would that not just nonexistence?
Also going faster than light is physically impossible because as far as we know in modern day physics if you travel at the speed of light you become light/energy basically derived from Einsteins theory of relativity. If you have become light/energy how can you propel yourself in a speed that goes faster?
written in a hurry which means it could be somewhat badly worded.

Well technically we are in a way in the fourth dimension since it is time and space. Physically at this point in time we really can't control how fast we go enough to effect things like I was saying early with time and space is relative. The closest thing to the 4d is a blackhole which sucks in light and everything else so if we were able to move around in a black-hole (theoretically since it would completely rip you apart upon getting anywhere near it) you would be moving at such a higher speed then anyone else so you would age slower but not sure how much that helped.

No I get what you're saying, and I often wonder about black holes. Quite frankly I'd give my life just to hop into one; given nobody who ever would comes back to tell the tale. It would be a nice end, and perhaps I'd live a bit longer than anyone expected.. Everyone says your strung out like spaghetti, though perhaps it doesn't distort your actual body... Seriously nobody really knows what the fuck happens in a black hole, we just know it doesn't come back. It's possible there's a connection to the 4th dimension.. given whatever goes in just kind of.. "disappears".. Though the only thing strong enough to cause a black hole is the collapsing space and time of a star/planet; correct? I know the process of a dying star and everything, but I wonder if it's possible to recreate on a small scale.. Probably not because black holes are supposedly these massive growing vortex's of destruction but still..
PERHAPS BLACK HOLE = NETHER PORTAL
-
Lol some people believe that a blackhole is a portal into another dimension but tbh I have no idea but I don't believe it does anything except completely disintegrate you. Although I found it cool when spock and nero were pulled into that blackhole and thrown into the past I guess (not sure can't remember). But in that sense moving forward is possible but moving back in time is not possible. But from what I have learned the reason it is black inside of a blackhole is because it sucks in and destroys the light along with everything else.
-
The theory of time I subscribe to is that it is basically how fast we are travelling through space. The faster you go the faster time passes. As for black holes their immense mass causes their particals to go extremely slow through space. Because of this if a human were to enter a black hole time would go extremely slow although it would probably feel like the same amount of time is passing as when you aren't in the black hole. Like Sprite said you would be torn to pieces because the "gravity" is so intense, it would just take a very long time.

The 4th dimension is time/space. It is a very confusing concept but I find it fascinating when I can understand it. The only thing that I can remember at this time is that time and space are relative. So the speed of light is the same for all observers but this is where you get into time travel. If your able to somehow go faster the the speed of light for about a year and then return to earth you would have aged 1 year while the rest of us aged 60 or 70 years. It is so much more complicated then that but that's all I got.
Problem is in order to go the speed of light you have to be light, and matter can't turn into energy.
-
As far as we know. You have to remember that this is all just theories for the most part that we're throwing around here.

Yup, but if ever, it'll probably be a very long time before stuff like this starts being disproved.

I wouldn't say very long, I say it's within our grasp; or if not our grasp, our lifetimes. Maybe not Cadavers, but perhaps our lifetimes. Honestly, look at the progress we've made in 30 years.. and now imagine if we made the same, or better yet DOUBLE the progress in the next 30...
Muahaha!

I beg to differ. Look at how much stuff we have discovered in the last 100 years. Be a little optimistic :)
Damnit pillz beat me to it.

That is exactly my point unless we ever find a way to go faster than light or find a way to survive moving through a black-hole time travel is impossible its not like how the movies portray it.

Umm matter turns into energy every single time a fission takes place or a fusion takes place E=MC^2.
LITERALLY MATTER CONSISTS OF ENERGY.

Also you guys need to read http://en.wikipedia.org/wiki/White_hole .
Entering a black hole it will drag on you more and more the closer you get, so it will drag you unevenly therefor dragging you in half or making you into spagethi.
The time aspect of a black hole is that close to the middle of a black hole it literally defies what we know as natural laws, light can no longer escape at all and it is percieved as if time has stopped.
-
1. Record a video of moving light
2. Speed up the video
Congratulations, you just recorded something faster than the speed of light!
3. Roll in profits.

But I wonder if hypothetically; if one was being spaghettified, is that something we feel, like our nerves and muscle is being twisted and ripped; OR is it just a distortion of reality/matter/time that we don't even feel as it happens.. perhaps not killing/destroying what enters the black hole.. simply spitting it out after it's done..
That would mean the purpose of black holes is: once there's too much matter/energy/whatthefuckever going on ( a star/planet/whatever explodes ), everything collapses and starts emptying shit across the universe.
It's that or they simply just become evergrowing holes of death that just obliterate everything that enters them forever. Really if that was the reality, doesn't that mean that one day the universe will be covered in black holes until it's swallowed hole? It's strange, thinking about their purpose.
Regardless; that's off topic BUT I'LL ALLOW IT. BLACK HOLE DISCUSSION IS NOW A PART OF THE FOURTH DIMENSION DISCUSSION.

Let me rephrase that: People and objects can't be transformed into energy, carried around faster than the speed of light, and put back together in one piece.

Almost correct, light = information and from information we can recreate. Which means we could potentially recreate said object but it would be extremely energy consuming among other things + if it was a person the personality of that person would already be completely dead and you would just have created a clone basically.
@Pillz I would wish a human being could last as far into a black hole that it would notice the time distortions and also notice how our natural laws are being demolished in front of us, but sadly the spagethisation or dismemberment starts way earlier than the part of the black hole that does that stuff.
Also from what it seems (to me) the stuff that comes out of a white hole is only light, which would mean a full conversion from matter to energy.

So basically a black hole would destroy you and spit you back out, just like it does to the stars it swallows. It definitely isn't a portal of any kind, it's just a hurricane in space.. It's a "storm" of gravity and other elements from the collapsed star it once was and whatever else it swallows. After looking at a few videos and reading on it; I don't think it's any kind of portal or anything other than a destructive force. White holes are intriguing though..

Random fact for fun I learned in one of my physics lectures since it relates here. 1 second is equal to 9, 192, 631, 770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.

So I actually just read a book on this, and I'm not sure if I understand some of it yet (Maybe once I get my Physics major), but from what I read there is another concept of a "fourth dimension" that people tend to confuse with time being the fourth dimension. In theoretical physics, time is the fourth dimension, and that's where you get into Einstein, light, general relativity, and all that jazzy stuff. But in Mathematics, there is another concept of the fourth dimension classified as a "Euclidean Dimension". Basically, it follows the logic (I'll try to explain it the best I understand it) that in a 0 dimension universe, nothing would exist. The universe would exist as a point, no more, no less. A 1 dimension universe would exist as a line. No height or width, just length. (See where I'm going with this? x,y,z coordinates. Purely mathematical, no physics involved in this concept). A 2 dimension universe would exist as a plane. no height. It's hard to imagine anything existing without any height, but that's just due to how we humans perceive our universe, which brings us to 3 dimensions, the world we live in. (Again, excluding time because this is conceptual mathematics, not theoretical physics.) Three dimensions, width, length, height; or the x, y, and z coordinates, respectively. Then we move on to the fourth dimension. So with 0 dimensions, we drew a line 90 degrees to that point and made a 1 dimensional universe. Draw a line at 90 degrees to the 1 dimension, and we get 2 dimensions. Draw yet another line perpendicular to the planar universe, and we have our 3 dimensional one. NOW. Try to imagine drawing another line, at 90 degrees to the other lines already drawn, and you have your fourth dimension. Sorry for such a lengthy explanation (hopefully I made it clear enough), but that's just another view of the fourth.

It must be impossible! Defining the laws on physics and math!! AHHHH Meme8
-
Another way of explaining: If you took a point, added another point, connected them with a line, you'd have one dimension. Add another point equally spaced from the others, connect that to the other 2 points, you have a 2D triangle. Add a 4th point (again equally spaced from all of them), connect it to the 3 already existing points, you have a pyramid. Add one more point (equally distanced again) , connect it to the others, you have a hyperpyramid. (Four dimension triangle)

In theoretical physics, time is the fourth dimension, and that's where you get into Einstein, light, general relativity, and all that jazzy stuff. But in Mathematics, there is another concept of the fourth dimension classified as a "Euclidean Dimension". Basically, it follows the logic (I'll try to explain it the best I understand it) that in a 0 dimension universe, nothing would exist. The universe would exist as a point, no more, no less. A 1 dimension universe would exist as a line. No height or width, just length. (See where I'm going with this? x,y,z coordinates. Purely mathematical, no physics involved in this concept). A 2 dimension universe would exist as a plane. no height. It's hard to imagine anything existing without any height, but that's just due to how we humans perceive our universe, which brings us to 3 dimensions, the world we live in. (Again, excluding time because this is conceptual mathematics, not theoretical physics.) Three dimensions, width, length, height; or the x, y, and z coordinates, respectively. Then we move on to the fourth dimension. So with 0 dimensions, we drew a line 90 degrees to that point and made a 1 dimensional universe. Draw a line at 90 degrees to the 1 dimension, and we get 2 dimensions. Draw yet another line perpendicular to the planar universe, and we have our 3 dimensional one. NOW. Try to imagine drawing another line, at 90 degrees to the other lines already drawn, and you have your fourth dimension. Sorry for such a lengthy explanation (hopefully I made it clear enough), but that's just another view of the fourth.
The man that stunned all the stoners in CG
Not such a bad way to start my reputation on the CG forums. :D

I can't fucking picture it! Just like trying to picture a color that doesn't exist.
This text below makes things a little more clear. You still can't really picture it, because we can only really imagine things in our third dimension. We are not fourth dimension entities.. Carl Sagan sometimes made it seem like he could perceive the fourth dimension; but later Hawking said he has troubling imagining the 3rd dimension, let alone a fourth.
Quoted from some website forum somewhere:Alright. So you guys already know that the first dimension is simply a line (according to our 3-space perspective).
The second dimension extends a line at 90 degrees from the first, creating a plane.
Adding yet another line 90 degrees from the first two lends a cube. You may spare no great expense visualising the corner of a 'box' to see the corner has three line elements; all at 90 degrees from each other, that lend it the property of the cube.
Now here comes the tricky part: Add another line to the corner of our cube; 90 degrees in relation to the other three lines, and we obtain the hypercube ("Tesseract"), which is the fourth-dimension analogue of our regular, ol' cube.
Now I'm asking if the human mind is capable of visualising something like this. I have a hypothesis that answers this in the affermative, but I still need help. But first, some background.
A 3-D sphere entering then leaving the second dimention would appear as a circle that starts from a point, grows to the max diameter of the sphere, then shrinks back into nothingness
Likewise, a hypersphere entering our 3-D space would appear to us as a regular ol' sphere beginning at a point, growing to the maximum diameter of the hypersphere, then decreasing in size to nothingness.
A 2-D organism would observe the sphere entering his universe as an object with depth and height, but no width. We may interpret this as an infinitely-thin sliver; an infinitely thin slice of a 3-D sphere.
As 3-D organisms, we percieve the 4-D hypersphere entering our universe as a regular ol' sphere having height, depth and width but not omega (omega is the fourth-dimensional line element. Thus, we have width, length, height and omega). The fourth-dimensional organism would interpret the sphere we see as an infinitely thin slice of his hypersphere.
Interesting properties:
When we, as 3-D organisms, look at any surface in our universe, what we're actually looking at is second-dimentional planes. Just look at a box if you don't believe me: The box you're looking at is consisting of three planes joined in 3-space to form a cube.
Likewise, the organism in 2-space, when looking at his square, is actually looking at lines. Two of them, provided the corner of the square is seen.
It stands to reason, therefore, that any fourth-dimentional organism looking at the surface of his hypercube would actually be looking at cubes. That's right: The surface of the hypercube is the cube, just like the surface of our cube is the plane.
Here are some helpful pictures and shit.

Supposedly, the hypercube. What the cube is to the square, the "Tesseract" is to the cube. This is a famous gif kind of showing how it works.

Actually, watching that cube move for a while shows actually how simple it is.

If by that you mean rapes your mind from behind then yes, yes it does.

Not really, the cube just turns itself inside out, the inner cube stretching its top out to become the top of the outer cube, then the top of the outer cube going around and becoming the bottom, and the bottom going inside to create the bottom of the small cube. All it is is just a bunch of moving parts.
Just a cycle. The only think that makes it complicated is the amount of moving parts, in fact it'd probably be easier to see if it wasnt always rotating.
Inside goes out top, outside top goes around to bottom, bottom goes inside.
