Isn't the 4th dimension actually TIME?

>Isn't the 4th dimension actually TIME?
There's more than just 4 dimensions. If they want to exclude time but include another one, that's a legitimate decision.

Way to go, OP...you SERIAL KILLER!

Time is same as space.

Time is not the "4th" dimension. But rather the "additional"/last dimension. In a classical physics, you have a 3 dimensional world and then time. But with modern understanding of QM and such, you have roughly 10-11 dimensions and the time is the other side of those dimension.

i kinda like the show but i couldn't get my mind off how W is just X. i hope i forget it so i can watch retarded anime for retarded people in peace

And you fags give Americans shit for being bad at math.

>>136266429
nah, it's just some fictive lolscience dimension

>>136266429
A dimension is a concept made up by humans. Whether time is a dimension really depends on the definition you're using. Time is a dimension when you define it as an axis of the object that you can 'draw' of everything that ever happened in a fixed space- and timeframe.

It's impossible to visualize a 4th dimension in three-space so they just took an easy way out.

>>136266429
we think it's time, but it could just as easily be gravity or something else

it's one of those "we don't know so we're guessing" things

>>136267914
Well, according to the manga, the dimension W is just some sort lolscience mishmash of fictive / parallel / ghost realities / dimensions where time and distance are inexitant, and that are mixed into some sort of energy.
The big towers over the world pump this energy in a stable way to avoid dimensionnal collapse and reroute it directly to the coils all over the world.
That's also why New Tesla keep the technology to themselves: they fear that if they share it, cheaply made coils would appear and wreck shit all over the world, as it's a very dangerous technology.
It's also why Kyouma hate coils: he saw some real shit that could happen and got massive >sufferings from it.

Just like you can project 3D to 2D, you can project 4D to 2D as well.

>>136271682
Yeah but it doesn't have much meaning.
casting a 3D object to a line (1D) or a 2D object to a line it'll just look the same.
To much information is lost and our brains can't even conceptualize a 4th dimension. It's pointless to try.

Physics grad student here.

It can be whatever you want it to be. There's no such thing as "THE 4th dimension". You just build mathematical descriptions of things that utilize a tool called "dimensions". It varies from model to model and subject to subject.

Say for example you have 2 particles in space. You can model that as 2 points in a 3 dimensional space right? But mathematically it's exactly the same amount of information as if you used 1 particle in a 6 dimensional space.
Another example is something used in physics all the time called "phase space" in which you treat momentum as dimensions.

In other areas of physics it's really useful to treat time as a dimension because if someone tells you where a party is and you show up 5 years later then you didn't make it to the right event. So it's natural to treat time as an extra coordinate to describe events in "spacetime". But calling it the "4th" dimension is meaningless, it might as well be the first, it doesn't matter.

>>136266429

In the inertial frame light moves at a constant speed for all other inertial observers. You could be traveling at 80% the speed of light relative to me, yet the light coming from me will be going 100% the speed of light and I will see the same from you. This also works in reverse so if you travel away from me the light which I detect will still be traveling the same speed of light.

Because the speed of light is constant for all inertial observers we can use it as an absolute ruler for space and time simultaneously. One light second is about the distance from the earth to the moon. As observers move closer to the speed of light space and time distort while the speed of light remains constant. The only way to resolve this problem is to treat both space and time as dimensions that dilate relative to each observer. According to light talking about space or time are just different ways of saying the same thing.

>>136272085
Yeah but perceiving things as 3D is something our brains are specialists at.
We can easily tell how far certain objects are in photographs, but that's a hard task for a computer.

if you assume there are only 4 dimensions then the fourth is time but hyphothetically if there was another spatial dimension time would be the fifth.
and it looks like dimension W is part of X because their world has an unspoken convention of using YELLOW to indicate it's a new dimension and not just the old one, they just forgot to say this in the anime. now stop being autistic.

>>136272242

But it does help not to word it in such a way that it may be interpreted that the existence of a fourth spatial dimension has been excluded from possibility.

All I was saying is there's no answer to OP's question.
What dimensions you're using depends on what area of physics you're considering, and in some cases even depends on the specific problem you're doing.

Even though it's standard to use time as a 4th dimension in relativity that doesn't make "time is the 4th dimension" into some fundamental statement about our reality. It's just a mathematical convention. Dimensions aren't nearly as special as most people make them out to be.
A physically 4 dimensional space would be special, but a mathematical model in which you have 4 dimensions is not, and which dimension is "the 4th" is meaningless.

Well, I've been pimping my crackpot black hole/dark matter/big bang hypothesis to /sci/ for years now and a vital part of it is that there are more than three spatial dimensions. So reading that there is no 4th dimension triggers me.

>>136272996
I didn't say that though. At all.

The word "dimension" is ambiguous, as it can either be a degree of freedom, or a scalar number assigned to how many dimensions a space has.

We might occupy a space "of dimension 4" or higher. But that doesn't imply there's any meaning in talking about which dimension happens to be "the 4th". It doesn't matter.

It's an easy way of showing that different coordinates in 3 space have a corresponding value in a fourth dimension that can't be represented well spatially in 2 or 3 dimensions without confusing most people. It would be the same principle as thermal images, except with the colours signifying different values of the W dimension. They probably didn't want to go with this if they thought of it though, since it would require a legend instead of just a simple graph that might be wrong. Because honestly. It's anime. I'm more surprised when they get something right.

>>136266429

They haven't explained what THE 4TH DIMENSION is at all, or why there are people who abhor the practice of exploiting it for material use. It might be a time lord, it might be heaven, it might be hell, it might be an alternate timeline, it might be your mother. What we can surmise is there are extractors all over the planet, and they're all probably bound to blow up at some point because the core premise of the series is a corporation recklessly taps into a dangerous power (which is a sensitive issue in Japanese society given how Fukushima was the result of a natural disaster colliding with a nuclear power company who didn't give a shit).

>>136274208
You've just gotta roll with the magical physics.

a dimension is technically any unit

the implicit understanding when you say dimension is spatial dimension but just the word 'dimension' in and of itself does not denote such a thing. There's a concept in engineering called dimensional analysis which is entirely about tracking units (time, mass, length, etc).

Let me help you out. Every show, book, movie, whatever you've ever seen that ever talked about anything being "from" a dimension or what "the Xth" dimension IS, is total bullcrap.

If you have 5 dimensions it's because you hand selected those dimensions to match the "dimensionality" of whatever physical theory or system you're dealing with.
Pretty much this >>136274424

>>136274857
It literally is. Just another piece of bunk material floating around that people always post which lends to the misconceptions that dimensions are physical things that we "discover" rather than mathematical tools that we are free to choose however we want to describe situations.

>>136275060
The states evolve in time. Time literally appears in Schrodinger's equation in a derivative.
It's not usually treated as a dimension though I guess. But that doesn't mean it can't be either.

In general relativity, using the Minkowski metric to measure the geodesic of a moving photon requires 4 variables, (t,r,theta,phi).
Basically, the azimuthal coordinate set with time as a 4th variable. This is from assuming a flat and expanding space (as observed).
This yields imteresting results, such as setting ds, the rate of change of distance between 2 points, to zero for a photon gives dr/dt = (+ or -) c.

I didn't say they were the exact same thing. I said they carry the same information.

I'm not sure what you mean with the matrices though. If you're referring to quantum mechanics then particle positions wouldn't be handled with matrices since it's a continuum and each point in space would be assigned its own dimension. So you have an infinite dimensional hilbert space.

But still the concept can be applied to other properties that would use matrices like spin for example. Two particles with their own spins would have eigenstates in different 2-dimensional hilbert spaces which can be expanded into a single state in a larger 4-dimensional hilbert space.

Not that guy, but he's technically correct in that the two representations are algebraically equivalent ("isomorphic") under elementwise addition/multiplication.

Do you even abstraction bro?

That's where the dimension of archetypes comes into play, as it ascribes significance to the three dimensions before it.

The extra dimension isn't bad, I mean it's a classic SF trope, the problem for me is that they tried to provide an explanation to it.
This is always a problem with cheap SF... if you create a universe with something hypothetical in it for your SF story, either make sure the math/physics are correct OR say that it happens "because x" but don't explain it, that way you get a "because magic" but instead of magic it's "science" and so suspension of disbelief holds.
The more you try to explain bullshit the more it sounds like bullshit, writing 101.
The intro especially, it fucks me up since they put the fucking explanation as a "and thus we have this SF setting", so every single fucking day_dog.jpg I have to see that fucking W dimension appear on the fucking X and then coil around like what is that kind of stupid shit?

That said, robogirls are my fetish so whatever.
