Well, first, I said "analogue". It is not a contradiction for an analogy to have its limitations and break at some point. But since you bring it up,...
How so? I was making a point about GR being a relativistic theory. Q-reeus countered with a situation where the relativistic nature of GR by itself...
What exactly do you think is its significance? Yes, the presence of an electromagnetic field affects the gravitational field in GR. If you were...
I think you missed the bit in emphasis. What I said applies to systems that are the same up to a coordinate transformation. So, for example, the...
I really don't see what you think is special about black holes here. It seems to be a general issue with the coordinate-independence of GR. In GR...
A correction: I just looked up the Tolman-Oppenheimer-Volkoff equation in more detail and it describes the variation of pressure inside a static...
So is the energy. Like I said, energy is not the same as the full stress-energy tensor. It is just one aspect of it. More precisely, the local energy...
That depends on the person. Most people don't care enough about GR for it to be worth spending months learning about in detail just to know the...
I didn't say "go do the math", but what you're paraphrasing here is a valid criticism. General relativity is a mathematically-defined theory and what...
Well first, as a simple matter of fact, the momentum density (and the rest of the stress-energy tensor) does vary depending on position. This is...
No. You're once again making assumptions. Angular momentum is handled via the stress-energy tensor just like everything else...
There is no contradiction in GR. Rather, you seem to be mixing GR with your own assumptions that contradict it. Specifically, you seem to be under...
Like DaveC426913 pointed out a spreadsheet should be able to do what you want, although you probably already know that. If for whatever reason you...
Similar here. The PhD student who was supervising me at the time told me "equations are part of your prose and should be punctuated" back when I was...
You use a '&' character to separate columns: A = \begin{bmatrix} a_{11} & a_{12} & a_{13} & a_{14} \\ a_{21} & a_{22} & a_{23} & a_{24} \\...
You really want to learn LaTeX for that sort of thing. An article What's Wrong with these Equations? by N. David Mermin is also highly recommended...
If you like technical stuff (like programming), you may want to look into learning LaTeX (https://www.latex-project.org/). It's a free software...
OK. Apparently Linux Mint doesn't automatically install the standard C headers when you install GCC for some reason. It's difficult for me to tell...
Cool. You shouldn't really need anything other than a text editor and GCC (if you installed it via the package manager) to compile beginner-level C...
So how is that going?
Separate names with a comma.
