I don't watch the show, and I doubt it's realistic (and I wouldn't care), but that makes less sense than saying an extra dimension was discovered (orthogonal, not parallel, to the normal 3 dimensions of space).

>>135943056

If you travel close to the speed of light between two 'stationary' points, you will experience practically no time interval. Going faster than light makes no sense because you can't improve your travel time below zero. It doesn't make sense to talk about increasing your speed relative to the observers beyond the speed of light either, because that means you can travel around a closed loop in space-time, violating causality.

The infinite mass thing is when you're travelling AT the speed of light. Travelling faster than the speed of light is just impossible.

You sound like imbecile that blindly swallows every bit of tripe thrown at him without question.

Photons have no mass. To travel FTL, you would need infinite energy. A physicist could explain this better. I recognize this is poor.

I'm not an expert in physics so I might be asking something retarded here, but aren't you always travelling at the speed of light relative to something, eg light particles being reflected from yourself? What is the "infinite mass" relative to?

>>135943943

No, it's just right generally, photons do not have any mass. But gravity affects the curvature of space and so photons can take different paths due to gravity.

>>135943249

>If you travel close to the speed of light between two 'stationary' points, you will experience practically no time interval

We can't even currently harness antimatter to any effective scale due to technology levels.

You aren't travelling at the speed of light relative to anything, since you have mass.

>>

>>135943943

>>135944046

Photons do have mass though. When they hit things they do impart an energy on them and push them.

Massless things can have mass, I don't really understand this much myself.

You keep saying this like it has meaning. It's the fastest you can move through regular space.

That means they have a momentum and energy, not that they have an associated mass.

Anti-Matter engines aren't for travelling faster than light, they allow you to hit higher speeds that come closer and closer to the speed of light and get tasty time dilation.

Black holes used to break physics.

We don't know the limits of technology yet.

Faster than light travel may be an impractical consideration now, but as we gain more insight a pathway may be found.

Even if the limit is absolute, if there is a way to practically act outside of the limitations, we will find and make use of it.

>>

>>135944091

>When they hit things they do impart an energy on them and push them.

They have energy and momentum, not mass.

Sometimes people make a distinction between "rest mass" and "relativistic mass," but physicists have moved away from this (sadly, not all textbooks.)

>>135944328

>No. If you're thinking p=mv or E=mc^2, think again.

See my image

>>

>>135944257

No, light (and any massless particle) is always moving at exactly the speed of light in your reference frame. You cannot Lorentz transform yourself into a frame that changes the speed of light because Lorentz transformations by definition preserve it.

>>

so light is not incestuous

so it explains while his D never reached the imouto

>>

>>135944066

It's not instantaneous in your reference frame, from the reference frame of light, the travel time is instantaneous.

>>

>>135944372

E^2 = p^2c^2 + m^2c^4

m = 0 for photons and thus E = pc, so their momentum is directly propertional to their energy.

>>

>>135944245

I hope field manipulation will become a thing, that it's possible. Create a vaccuum in the higgs field so all particles behave like they're massless.

>>

>>135942875

>>135942187

You can have a fourth axis t representing time, making what we call space-time with the xyzt coordinate. You're just ignorant.

It is.

>>135944087

there is no antimatter to harness in the first place. it's produced from energy, very inefficiently so.

think of it as energy storage, not an energy source.

>>

>>135944435

You have lost me.

>>

>>135944372

Well, see >>135944193

You could say "oh, if they have energy, they have an 'inertial mass' according to m=E/c^2," but that formula is only half the truth.

Actually, it is E^2=(pc)^2+(mc^2)^2, so for m=0, E=pc.

p is momentum, p=gamma*mv, v being velocity. Now for v=c, gamma is infinite, and with m=0, this is technically undefined, can be any finite value.

So, m=0 but E and p are not 0.

>>

if there is nothing faster than light how do you explain c-beams glittering in the dark near the tannhÃ¤user gate?

>>

>>135944284

Ah I remembered. For you to travel very close to the speed of light relative to the 'stationary' observers the space-time interval must be close to zero. Space-time interval is preserved in Lorentz transformations, hence in your own frame where you are stationary you experience very little time.

>>

>>135944245

Mass is just another form of energy, only made 'physical' by field excitations.

The way they've both worded it and visually (attempted) to project there implies a 4th spacial dimension. Which is nonsensical and inherently different to talking about spacetime dimensions.

That is a deep question, more than you might realize. A proton consists of two up and one down quark, yet there is a huge discrepancy between the sum of the quark masses, and the proton's mass. In a way, yes, most of the mass "comes from" the field/gluons that bind them together.

Time apparently doesn't exist past the event horizon, nothing does from our point of views and it apparently becomes another alternate time-line separate from this universe.

This probably doesn't answer your question, but for an observer free-falling into a black hole it takes a finite time to reach the singularity at the center.

>>135944684

Most of the mass of atoms is from the energy of the residual strong nuclear attraction between the quarks that make up the protons and neutrons, so yes. Most mass is just energy. Google the strong force for more information.

>>135944782

Have they've actually implied it's a spatial dimension that's supposed to work like the familiar 3? Introducing an extra dimension by trying to depict it as an extra axis in addition to the spatial ones isn't particularly nonsensical.

>>135944944

I really don't understand the Treaty, it seems more to appease normalfaggots than actually do anything.

>>

>>135944714

They're field excitations, they don't have a physical structure as we commonly understand it, no sides, no size aside from that created by their field interactions.

>>

>>135944943

Hence the energy-mass conversion via E=mc^2.

>>

>>135944684

I think it's pretty much the opposite with the commonly accepted model today. "Empty space" is a thing derived from the existence of mass/energy (the two are interchangeable).

This also calls into question whether the 4th dimension referred to in the OP, time (which is a patently stupid thing to be shocked at the "discovery" of) actually exists intrinsically or is another derived quantity.

>>

if you go near light speeds you atoms will move slower and become heavier

do they move slower because they became heavier

or

do they get heavier because they move slower

>>

>>135944991

No, they haven't. Treating it like an 'extra' dimension is just convenient because you can rework everything in tensor notation.

>>

>>135944991

Lumping them together with typical x, y and z which all have fairly consistent meanings in this case.

Unless of course they're using the terms abstractly, but lets be honest they definitely aren't considering they're talking about it in terms of a 4th dimension. And the show's description on funi's website supports that.

basically fuck you, that isn't how we'd do it, we're way too into not having to change the way we do things to just lump it in like that.

>>135945405

There is no 'the 4th dimension'

There is no 'the 3rd dimension' either

You can't just point to directions and number them as specific dimensions

If you have a pitcher of 3 cups of water, can you point to cup #2?

Time is like adding a cup of oil to the mix. It interacts with the other dimensions, but you can tell it's not quite the same in behavior.

There are 3 dimensions of space, and one of time.

A fourth spatial dimension is a mathematical concept that works take too long to get into , but here's a thing to help explain the concept: http://youtu.be/p4Gotl9vRGs

>>135945427

Do you really not see from the OP what's wrong with it?

>>

How the fuck else are you supposed to represent a 4th axis in a coordinate system?

Projecting a 3 dimensional coordinate system into 2d doesn't really work, it just feels normal since our brains can understand 3d.

But now you are projecting 4d into 3d and that into 2d, how the fuck is that supposed to look right?

>>

>>135945704

It doesn't, that's why is mostly theoretical math.

Fucking Google higher dimensional geometry.

>>

>>135945657

given a 3 dimensional space you can choose an orthonormal basis

so there are 3 dimensions

as for the 4th dimension I can't say anything

>>

>>135942187

That illustration is wrong, but the 4th spacial dimension is real enough.

>>135943659

All real theories.

Have to remember though that some of the interpretations the characters make are because they are in middle school and don't have the background to make more educated guesses. Tenjou lampshades it in chapter 7 iirc, "I'm in middle school, I don't understand this, I'm not an expert. But it's an explanation that makes sense."

It obviously exists and has been observed but cannot be contained for any decent period of time as of yet.

>>135945754

Saying 'the xth dimension' shows a gross misunderstanding of how dimensions work. There is no specific 'xth' dimension of space, there are simply x dimensions of space

~~Dark matter doesn't exist. It's theoretical basis is shit and MOND provides a more compelling explanation, while also predicting undiscovered phenomena (galaxies) unlike dark matter.~~

>>

>>135945859

no I am saying 4th can depend on what you choose and won't make much sense

but you can choose a basis for 3D space

You're an idiot with half-knowledge. Nay, fractional knowledge.

That's artificially generated antimatter. You see the word CERN there right in the headline? Does that ring a bell? If it doesn't: Particle accelerators.

I'm saying antimatter does not occur in nature in relevant quantities that would be harvestable as energy source. At best, and that requires significant breakthroughs, it could be used as a form of energy storage. You first have to put energy in to get antimatter (and matter) out.

the tl;dr version is that dark matter never existed, we just misunderstood gravity.

>>

>>135945704

projections are shit in general

you can do 3D->2D because it is easier to imagine

but if you think the 4th as time and try 4D-2D it doesn't even make sense

after all what guarantees time is perpendicular to other 3

You do realise dark matter has a laundry list of problems and has failed to actually predict anything right? just because theories are incomplete doesn't discredit them. But the fact dark matter has failed to make a single prediction should have made it a joke years ago.

>>

>>135946645

>You do realise dark matter has a laundry list of problems

dark matter IS a laundry list of problems.

There's no such thing as Dark Matter, it's a pure placeholder term for the discrepancies we see.

>>135946201

Nothing. Time isn't a spacial dimension anyways, not like x-y-z. Really, Time as the 4th dimension would be a lot easier to draw than a 4th spacial dimension (ie, not impossible) - just draw a person-tube.

>>

>>135946811

>spacial

it's spatial

>>

I don't understand how you would show a fourth dimension, but the reason the image is retarded is because it implies that there is a fourth spacial dimension that we simply aren't recognizing or aware of but works within physics as we know it.

>>

Gravity is merely a theory, by the way.

>>135946765

Which Milgrom himself addressed?

>>135946871

draw 3 dimensions on paper normally as you always do

write T=T0 below it

It is the cleanest way

>>135946871

From just that pic, doesn't imply that. It seems kind of stupid to assume it does.

>>

>>135942580

Good sci-fi.

Like Asimov or Lem. Pretty much every good sci-fi author was a physican or mathematician.

>>

>>135942187

I've not seen this, but how does it relate to the plot? Especially considering that a fourth dimension does not and cannot exist?

>>

>>135946871

The fourth dimension would be represented by a collection of 3dimensional charts aligned left to right infinitely.

>>

>>135942937

Not him, but the thing is - you got three axis, each being an infinite line, aka continuing in the opposite direction beyond the O point. There is no space on that coordinate system for a fourth dimension, as it already covers all available ones that can be physically observed. If anything, a fourth dimension would be intertwined with all three axis.

>>

Time isn't a fucking dimension, it's just a concept.

fuck me lads

>>

>>135947814

>it's just a concept

Just like dimensions. Just like anything in our theories.

>>

>>135947814

Time is far more than a concept, but it is certainly not a dimension.

>>

It's not even wrong, having a "fourth spatial dimension" is mathematically possible, just read Flatland.

>>

>>135942937

Their "fourth" axis lies on the other half of one of the existing axes, therefore not a fourth axis.

The best way to visualize a fourth axis would be showing superimposed xyz-axes. It would still be "wrong" but atleast not this stupid.

>>

>>135948004

as we can observe it is an arrow

probably an N dimensional continuum

>>

Has nobody here done any research at all?

https://en.wikipedia.org/wiki/Four-dimensional_space

The concept of a fourth spatial dimension (as opposed to X,Y,Z, time) is nothing new and its been explored since Flatland was published in 1884

>>

>>135946871

the best way to represent it would be thus

show that a 2D plane is an infinite summation of 1D line

and a 3D space is an infinite summation of 2D planes

then a 4D space would be a summation of 3D spaces

(concept of dimensional analogy)

Four dimensional space is nothing more than mathematical wankery.

At least say that about infinite dimensional spaces or something like that.

Everything in physics is mathematical wankery, if we depict in our theories that space is a 4 dimensional thing, then it is.

This thread along with the OP is beyond retarded.

You now must solve pic related to post anything related to math ITT

>>

>>135948694

3 dimensional space is a observation and description of our natural world, as is all of science. Anything that postulates about something that does not exist is wankery.

>>

>>135948473

>Everything in physics is mathematical wankery

Not at all. Physics describes the operation of the natural world. Anything beyond that is wankery. Nothing more than self pleasure using mathematical formulas.

>>

>>135942187

Just think of the stuff in your image as a new way to visualize the theory behind the new dimension. Mathematics and physics are full of crutches and freshly defined visualizations of stuff that's hard to imagine, so they can wrap their heads around it in an ordered manner. Just assume that it doesn't make sense to you, because no one here had the need so far to visualize dimension W yet and that the thing just looks like regular 3 axis system.

tl;dr don't strain your head over unnecessary stuff.

Or are you next gonna complain that you can't build a complete working template of a W coil from the schematics you saw?

> Physics describes the operation of the natural world

Wrong.

Physics makes models that best describe processes and predict things we see in the real world, the models themselves don't have to describe what actually happens in the real world, as it is impossible to know what really happens.

Hence physics is as much wankery as math.

There is no difference between noting that a projectile follows a parabola like trajectory or that space is a 4 dimensional space, because that is what see, hence it is what it is described at until a better model comes up, like new theories of mechanics, like relativity.

>>

Sorry if this has already been answered, but what show is this?

>>

>>135949421

That doesn't make any sense. Just because you cannot accurately describe the entire universe down to the most fundamental level doesn't mean that all of physics and science is wankery. Yes, physics is more or less an estimate of the workings of the universe, but it is a fairly accurate one. Physics has actual, real world applications. Imagining a fourth spacial dimension and writing up mathematical formulas does not, and is nothing more than shameless self pleasuring.

You couldn't just look up the subbed line in the OP?~~Hint: it gives the title.~~

>>

>>135949645

Except using said models with 4 dimensions we can make more predictions than before, hence it is useful in both physics and other real world applications.

In real world applications we use much more than simple 4 dimensional spaces, we even use infinite dimensional spaces in physics.

Because the bottom line is that dimensions aren't something special contrary to what you see in sci-fi, they're just a property of some mathematical structures.

When you identify such structures, you can use their properties.

You can view, for example, matrices as n by m dimensional spaces, and use properties of such spaces, which is something that is very useful in computing for example.
