@enumaris OK, thank you so much!
Aug 20, 2018 20:54
@enumaris could you share the link to the related Mathematica page? I couldn't find anything except a page with some information mathworld.wolfram.com/EinsteinFieldEquations.html
Aug 20, 2018 20:49
OK, one last question: Do you know a software or any implementation of Einstein field equations in a programming language so that I can tweak with the values and see what happens in my computer? Not necessarily a visualizer.
Aug 20, 2018 20:44
@enumaris but you guys said it's possible to calculate in 3D?
Aug 20, 2018 20:42
@ACuriousMind I'm not talking about the "expansion of space" actually. Please just think of the drawing of the Riemann tensor on a 3D graph. Wouldn't that drawing expands with a mass?
Aug 20, 2018 20:38
*expands
Aug 20, 2018 20:38
@ACuriousMind OK, what would be the comparison of applying the 3D Riemann tensor to each point in a spherical volume with no mass and applying the 3D Riemann tensor to each point in a spherical volume with some mass in it. Wouldn't it shift the points outwards when there is a mass? So that the spherical volume extends?
Aug 20, 2018 20:30
@enumaris so can we calculate the Riemann tensor just for 3D space? I mean excluding time dimension?
Aug 20, 2018 20:28
OK with calculating the Riemann tensor at each point we get a curved spacetime right?
Aug 20, 2018 20:26
@ACuriousMind so you say, we get "4d array of numbers varying at each point in spacetime" as the output from the Schwarzschild metric?
Aug 20, 2018 20:24
@ACuriousMind OK, let me simplify my question. The Schwarzschild metric is a special case of Einstein field equations for a spherical mass, with no angular momentum, no charge etc. right?
Aug 20, 2018 20:17
@ACuriousMind by "extra space" I mean the increased area/space in this kind of an analogy en.wikipedia.org/wiki/Einstein_field_equations#/media/…
Aug 20, 2018 20:14
@enumaris by "total curvature" I mean the total difference in the curvature of space caused by the mass. If there is no mass it's flat space right? Then think that suddenly a single blob of a spherical object with 9 x 10^{10} solar masses worth of luminous matter appeared in the vacuum. So how much it bends the space and creates extra area/volume when it compares to vacuum state of that space.
Aug 20, 2018 20:02
@enumaris do you know a research done in this topic? I mean I can't be the first person in the world who wants to know the total curvature of the Milky Way Galaxy, right? I scanned the literature for a while but couldn't find any result.
Aug 20, 2018 19:57
@enumaris what do you mean by "embed space-time in a higher dimensional manifold "?
Aug 20, 2018 19:54
Hi, is there a method to calculate the total curvature created by the mass of luminous matter in the Milky Way Galaxy? My goal is to find the extra space created by that curvature.
Aug 31, 2017 20:19
@Blue oh OK, I will be waiting...
Aug 31, 2017 20:18
I think I found an equation to calculate the dark energy mass in per 299 792 458 m^3, don't you have any comments?
Aug 31, 2017 20:10
Could someone briefly review this paper of mine? (researchgate.net/publication/…) I'm curious about your comments...
Mar 12, 2017 00:09
@ACuriousMind OK, thank you very much. I understand the problem.
Mar 12, 2017 00:04
So in the future maybe I do not make the same mistake if I understand the problem.
Mar 12, 2017 00:03
What was wrong with my question could you explain as an experienced user?
Mar 12, 2017 00:03
Hello, I have asked a question and get many downvotes: physics.stackexchange.com/questions/318140/…

@AlanMunn @cfr \\begin{circuitikz}[every node/.style={scale=0.5}] partially fixed my problem, thanks for your help :)
May 2, 2017 03:38
@cfr this was a simple example to demonstrate if you make -400 to -600 it will exceed. Have you ever looked the other links I provided?
May 2, 2017 03:03
@AlanMunn I don't understand about \ctikzset{bipoles/length= could you give me an example?
May 2, 2017 02:50
no it's not possible with that either :/ it's disturbing the balance if I scale down to 0.5 I need to multiply x by 2 so what's the point of scaling down?
May 2, 2017 02:45
OMG it's possible with \begin{circuitikz}[scale=0.01] I spent 3 hours to figure it out lol.
May 2, 2017 02:39
Can I scale down the logic gates?
May 2, 2017 02:37
Here you can see the overlapping logic gates: imgur.com/a/i4NpY
May 2, 2017 02:34
If you change -400 with less than -500 or more than 500 you will get Dimension too large error.
May 2, 2017 02:33
Even though I'm trying to go further I'm failing to prevent overlaps.
May 2, 2017 02:32
The purpose of using such values like y=1500 is preventing the overlapping logic gates. I couldn't find a better solution if you have any please tell me.
May 2, 2017 02:31
@AlanMunn this is the file I'm dealing with: gist.github.com/mertyildiran/baf9269271a04ac4151dd7d5695314a7
May 2, 2017 02:27
OK I will give you the files wait please...
May 2, 2017 02:09
@AlanMunn it's a TikZ package yes.
May 2, 2017 02:09
I'm using this package: \usepackage{circuitikz}
May 2, 2017 02:08
nodes are logic gates like: \node[nand port] at (10,1500) (nand2) {};
May 2, 2017 02:07
@AlanMunn @cfr x,y coordinates y=1500 for example
May 2, 2017 01:01
hi, I have a huge LaTeX file generated programmatically. I need to place nodes around 1500 or -1500 but I'm getting Dimension too large error. How can I increase the maximum dimensions?
