<h2>Questions of Interest</h2>

- to discuss and bring meaning to
- the 'warp metric'
- the shaping function
- york time
-energy density

Archaelogical and archival
- Where are the deepest historical records that discuss the warping of space
- Is there a human sensory faculty that could theoretically detect an externality of a such an anomoly?
- is there evidence of current technology already deployed?

purposed goal

look for or make a little python app that can toggle the values of the functions,
extend this app with 'Bubble oscillation optimization'

-toggle this optimation with various parameters for cool graphs :D :D
-Fish for control mechanisms to perhaps guide the bubble from position A to B

Have fun for the math of it :D

<notes>

on '<b>Alcubierre Metric</b>'

"... Since the expansion and contraction of space does not have a speed limit,
Alcubierre developed a model (metric) within the domain of general relativity that uses this physics loop
hole and has almost all of the desired characteristics of a true interstellar space drive, much like what is
routinely depicted in science fiction as a “warp drive”."

ds^2 = −c^2dt^2 + [dx − v_s(t)f(r_s)dt]^2 + dy^2 + dz^2

x,y,z 'euclidean' coordinates
t time

curve = (x= x_s(t), y = 0. z = 0)

v_s is the velocity of craft in crafts frame

subscript S is the radial position in the view of spacecraft origin

question: does this mean ds^2 = 0 is a warp ship moving along the x-axis?

f(r_s) coined 'top hat' is the 'shaping function'

' For very large σ, the wall thickness of the bubble becomes
exceedingly thin, approaching zero thickness in the limit'
<i> shields up Scotty</i>


'The driving phenomenon that facilitates
speedy travel to stellar neighbors is proposed to be the expansion and contraction of space (York Time)
question -> phi the gas pedal?


" As the warp bubble thickness is decreased, the magnitude of the York
Time increases. "

Energy Density:
' For a
fixed target velocity v_s and warp bubble radius R, varying the warp bubble thickness σ changes the
required peak energy density for the field at a fixed velocity. '

Yes, turns out space its self may be akin to a fluid. If i'm understanding the work done here, we can, like water, make waves of it which constructively and destructively interfere, and let's not even imagine how Heisenberg uncertainty principle would apply.

I have an intuiition that an AI will be able to construct a 'warp resonance' schematic, which may be able to soften space time by constructively interfering high energy electromagnetic waves

>>11474947
From what i gather the warp metric describes the position and momentum of of a warp ship at a time.

That velocity term is that of the spacecrafts moving frame, so i suppose akin to watching a warp ship hover over Capitol Hill and than iterate dt once and and observe the bubble

I think it will come in incredibly useful, like how different notes come to make a chord, so should multiple EM waves harmonize into cavitites of soft and hard spacetimes

I have a few questions.

1)what does [math]ds^2[/math] mean?
2)what does the variable s represent?
3)is d a metric or a derivative?
4)what do they mean by metric? Do they mean it in the usual sense, as say the euclidean metric?
5) what is this based on? Seems like results from relativity

[Anonymous No.11475114]

>>11475014
According to the 101 paper the s subscript describes the radial axis. I'm guessing s is a function of x, y, z. But i'll have to dig deeper into this 3 + 1 formalism of general relativity. https://arxiv.org/pdf/gr-qc/0703035.pdf

My intuition is, that because the warping of space changes the angle by which x,y and z axis are crossing, like how light will curve around a black hole, thinking its going straight, we need a function that describes this curve. definitly could be way off though


Digging into the original paper
https://www.researchgate.net/publication/1963139_The_Warp_Drive_Hyper-fast_Travel_Within_General_Relativity

'Let us now assume that our spaceship moves along the x axis of a cartesian coordinate system. We want to find a metric that will “push” the spaceship along a trajectory
described by an arbitrary function of time x_s(t) . A metric that has this property is given

'some jagon equations'

to v_s(t) = dx_s(t)/dt and r_s(t) = [(x-x_s(t))^2 +y^2 + z^]^ 1/2

It seems we need to construct a radial definition of our velocity and position for the warp metric to spit out something meaningful

so for 1) i suppose ds^2 is the second partial deriviative of the radial position

2) radial position

3) I'm pretending metric and deriviatives are the same thing, I would love to know the laymans difference.

4) yes, it appears this result stems from this '3+1 formalism' of general realtivity

[Anonymous No.11475155]

>>11475114
>Second partial derivative of radial position
What do you mean by radial position?
Second partial derivate with respect to whom?
Why is it written with a [math]d[/math] instead of with a [math]\partial[/math] then?

>I'm pretending metric and derivative is the same thing then
No no no no they're completely different things.
In the general context of analysis and topology, a metric [math]d[/math] on a metric space [math]\mathbb{X}[/math] is a function [math]d: \mathbb{X} \times \mathbb{X} \rightarrow \mathbb{R}[/math] such that if [math]x,y,z \in \mathbb{X}[/math] then the following is true:
1) [math]d(x,y) \geq 0[/math] and [math]d(x,y) = 0 \iff x = y[/math]
2) [math]d(x,y) = d(y,x)[/math]
3)[math]d(x,y) \leq d(x,z) + d(y,z)[/math]

A derivative on the other hand is a linear transform of a function defined as follows ([math]dy/dx[/math] does not denote a fraction)

[eqn]f'(x) = \frac{dy}{dx} = \lim_{x \rightarrow x_0} \frac{f(x_0) - f(x)}{x-0 - x}[/eqn]

[Anonymous No.11475160]

>>11475155
Shit, small typo, I meant:

[eqn]f'(x) = \frac{dy}{dx} = \lim_{x \rightarrow x_0} \frac{f(x_0) - f(x)}{x_0 - x}[/eqn]

My point is, I dont understand what these physicists mean when they talk about a metric.
That warp metric thing seriously doesnt look like a metric.
Then they talk about a "metric tensor" and make this even more confusing.
Can a physicist please clear this up?? I'm actually genuinely interested.

[Anonymous No.11477659]

>>11477565
How is learning general relativity, and testing that knowledge by building a computer model of a complex formula that can be hooked up to AI something that is unrealistic?

This is a great project to extend ones understanding of physics, mathematics, and software engineering, Is a bonus because thinking about warping space is fun

Also, If you haven't noticed, this model is well thought out, and worked on by some of the finest scientists the world has too offer. Who cares if it appears unrealistic today, the tangential knowledge of this persuit is worth it enough

Now, did a physicist stumble in here and have an answer to >>11475422 guy?

Dude, since you still refuse to get the simplest fact here; all time-critical functions in python are implemented in either C or Fortran. That way, you have the ease of programming in Python with almost the swiftness of C.
Again, read the description of what he did there. If you're retarded enough to implement array sorting yourself in a scripting language, it's not the language's fault.
