Does this equation (Einstein’s field equations in general relativity) equal 12?

[BadgerBadger92]

This is a weird post but I posted on Facebook Einstein’s field equations in general relativity and I thought there could be numerous answers to this equation but some girl responded the answer was 12. Am I right in that there are numerous possible solutions or does it truly equal 12? Or is there something relating to this that does equal 12?

The girl got it wrong. Actually, the answer is 42. See https://simple.wikipedia.org/wiki/42_(answer)

Does what equal 12? R? g? Something else?

The entire equation itself. I thought there was something fishy with her answer

The $\mu$ and $\nu$ are indices that each take four different values - so that is a compact way of writing sixteen (4×4) equations. The number 12 is not sixteen values, so cannot be equal to the equations.

Somebody is pulling your leg.

I thought so. She claimed to have a higher IQ than Einstein which I doubted after seeing her “answer.”

You mean you have never read it, right?

There was a movie too but the book is better in my opinion.

Yes, I have seen ii, but it seems that he thinks that there is only a movie.

Or the TV series.

It was a radio series originally, then a book series, then a TV series, and many years later a movie.

She would not know that because on one ever measured it, there are only estimates but they are a best guess.

The book is definitely best IMHO. It basically reads like one long standup routine with a "plot".

"He was so mad that for a moment he seemed to be steaming!"

"40 billion tons of hydrogen gas rose slowly above the swamp and managed to look slightly damp."

(Possibly paraphrased)

EDIT: Although, to be fair the movie did a good job.

It's not about IQ, it's about knowledge one has.

It's not about IQ, it's about knowledge one has.

Also, a lot of people take online IQ tests that aren't necessarily reliable. There's an old observation that the average reported IQ online is about 150.

I don’t trust online iq tests. I’ve taken one out of boredom years ago and gave me the ridiculous result of 200.

Not to distract from the movie references, but a solution of the EFEs is a spacetime manifold M with Lorentzian metric g (M, g).

There are an infinity of such solutions depending on what you set as the stress energy, T, of matter in the space time. Even in the case the stress energy is zero, you can have different solutions for different symmetries (Schwarzschild, Kerr, etc.).

If your friend figured out how to crunch all of that into the number 12, maybe she really is smarter than Einstein. :)

I asked her what she meant and she said this

“When equations are divisible by 1/2 and your solution is equal to the sum of 4 in most cases 8 is half the sum of 4 squared and 16 is the sum but 12 is 1/2 squared so when 2 is not subtracted or limited to the sum you get 12 every time.”

Is this really her answer!? And if it is, are you really unable to tell if it makes sense or not!?

The entire equation itself.

In reference to the statement that the equation was equal to 12, an equation is not "equal to" anything. An equation can be true for a certain variable or collection of variables, always true, or never true.

“When equations are divisible by 1/2 and your solution is equal to the sum of 4 in most cases 8 is half the sum of 4 squared and 16 is the sum but 12 is 1/2 squared so when 2 is not subtracted or limited to the sum you get 12 every time.”

She was trolling you...

I don't trust that result, either.

Any equation is divisible (on both sides) by 1/2. For if x=y, then surely 2x=2y. Therefore by the argument given, you get 12 every time. Every equation is 12 in disguise. She even said the square of 1/2 is 12 and when you assume a contradiction you can prove anything. Therefore, seems legit to me. :)
