You are antagonizing wherever me maliciously, and this is not academic discussion,Your science may be, but the rest of the world is doing fine, thank you.

This parameter is superfluous in the solar system, not always there. to plus this parameter, you have to assume that it's small enough, which means to add a more hypothesis,and science is rigorous and can never add hypothesis optionally. Einstein thought that adding cosmic constants was his biggest mistake, and Einstein's understanding was profound. Unfortunately, later generations did not understand Einstein, once encountered difficulties to continue to add cosmic constants, this is the folly of posterity. Please remmber that the random addition of parameters or hypothesis may make any calculation meaninglessSee, this is why I know you don't understand it. It's not adding a parameter; the parameter was always there. No equation is being changed; the parameter was always there. Leaving it out would be an additional assumption. That your math skills are too poor to understand this, doesn't mean it's wrong.
Says the person that changed the subject away from the factor 2...Don't change the subject.
Please don't put words in my mouth. Where did I say that information came from a paper?Please recommend the paper I asked for.
Again, read the textbooks, and search online to all the students (or people in general) that have pointed out problems with the establishing of the coefficient.since you say that a lot of students are talking about the coupling coefficient,is it difficult to recommend a few articles on discussing the coefficient?
As you've demonstrated multiple times in this thread: you indeed don't.don't I understand cosmic constant?
*BOOM*you understand, oh, do you know shame?
Says the person not able to provide any evidence for most of his/her claims.What else can you do besides sophistry?
So now you're backpeddling on your comment in post #534? Typical.You don't have any innovation,
That's a contradiction.you just insist in old theory in the name of innovation.
Except it isn't, as we've discovered in this thread.Yang's modifid theory is the improvement on the shoulders of his predecessors,
Wait, now innovation is something positive again? Which is it?so it is the most powerful innovation and the real progress.
Says the person that has been insulting me and calling me names throughout this thread.You are antagonizing wherever me maliciously,
No, thankfully for you, because in an academic setting, you'd have to prove your claims, instead of dodging questions and issues.and this is not academic discussion,
Neither is the Hubble constant, so you're also arguing that's a mistake too.This parameter is superfluous in the solar system, not always there.
If it were large, it'd be easily measurable in the solar system. So your argument is circular; you are using the fact that it isn't (easily) measureable in the solar system to prove that the cosmological constant is small-ish (which is true), and then you argue that thus it cannot be large, so it must be false. You are attacking your own assumption.to plus this parameter, you have to assume that it's small enough,
False; as I said, it's a free parameter. That you don't know what that means, doesn't mean it's not.which means to add a more hypothesis,
And it wasn't. That you don't understand this, doesn't mean it's bad science.and science is rigorous and can never add hypothesis optionally.
No, you believe Einstein was wrong about the EFE entirely, remember?Einstein thought that adding cosmic constants was his biggest mistake, and Einstein's understanding was profound.
And neither do you, as you've demonstrated in this thread.Unfortunately, later generations did not understand Einstein,
Except the truth is the total opposite. But clearly, you don't know what you are talking about.once encountered difficulties to continue to add cosmic constants, this is the folly of posterity.
Please remmber that the random addition of parameters or hypothesis may make any calculation meaningless
It's not difficult to have patience when truth is on your side.I am not able to figure out who of the two has better patience.
What gave it away?Both seem to relish this ongoing word mumbo jumbo.

That is a direct contradiction with the claim that pressure is negative. So which is it?I'm here to introduce Yang's achievements. The key to this achievement is to modify the coupling coefficient of the field equation, that is, to change the original -8 to the present 4, and the pressure is proved to be negative. This modification is essentially to seek another more reasonable static spherically symmetric weak field approximation's solution to the field equation-----note that the coupling coefficient and pressure are also solved together with the metric as an unknown number, unlike before, pressure was treated as zero in advance.
See? Pressure must be negative, but you just said that pressure was treated as zero. You can't have both.To ensure that a new and more reasonable metric can occur, Yang found that the coupling coefficient should be 4paiG but not the provious -8 paiG, and the pressure must be negative.
And I never claimed otherwise.The whole calculation process is clear and clear, step by step, and there were also 2 in the middle, but there was no special significance.
You still don't understand: if two people derive the EFE, and one gets a coefficient of -8, while the other gets 4, at least one of the two must be wrong. You claim only Yang is right. I'm skeptical that all those tens of thousands of GR-experts are wrong.there is no factor 2 problem, but you try to tangle factor 2 over and over again and treat it as a problem,
That you don't want to face the music is your problem, not mine.this is clearly your misconception and you bring up unnecessary ramifications.
No, the disgusting part is the part where one of us continually ignored many issues, dodges questions, and doesn't understand half of the established cosmological knowledge that's brought up.But instead of looking at yourself, you continue to mess with it, you're too disgusting.
Obviously? Well, let's see the evidence for that then! If it's obvious, it should be easy for you to prove.obviously, you are lying,
... Are you schizophrenic? Why are you talking about yourself in the third person?heyuhua never said such words,
And I never claimed otherwise.that is Hayden's, who is another Registered.
Again, name calling. How very mature of you.You don't even see the door, you shit
And thus Weinberg proves Yang wrong: there needs to be a coefficient of -8, not 4. That's what the factor 2 business is all about. You know, the thing that you, just a few posts ago, said wasn't a problem, that was my misconception. Well, clearly, Weinberg says otherwise. (As does Carroll, by the way.)announced again,the Ricci tensor we use is the Wimberger's definition, not the carroll definition.The difference between the two definitions is a minus sign, that is, Rij defined by Wimberger=- Rij defined by Carroll. therefore, using Wimberger's definition the original field equation is Rij=-8paiGS ij, and using carroll's definition, the original field equation becomes Rij=8paiGS ij, these two equations are completely equivalent. Here Sij=Tij-gijT/2. Obviously, Yang's modification aimed at Rij=-8paiGS ij, not considering Rij=8paiGS ij,
here I is still to say that pressure is negative, no contradiction. Of course, the conclusion that the pressure is negative is proven rather than a new hypothesis, that is, the negativs pressure is solved from the field equation rather than artificial imagination.That is a direct contradiction with the claim that pressure is negative. So which is it?
The fact is that, Weinberg did not prove Yang was wrong, but Yang proved Weinberg was wrong. If he saw Yang's demonstration, would be admired because Yang's demonstration was indeed higher level than he didAnd thus Weinberg proves Yang wrong: there needs to be a coefficient of -8, not 4.

(As does Carroll, by the way.)
OK, I understand now: that particular statement was just broken language.here I is still to say that pressure is negative, no contradiction.
Yes, and the conclusion reached thus demonstrates that this EFE is not compatible with our universe: matter does not generates negative pressure in ours.Of course, the conclusion that the pressure is negative is proven rather than a new hypothesis, that is, the negativs pressure is solved from the field equation rather than artificial imagination.
As I've asked you multiple times: point out where Weinberg makes a mistake. And Carroll. And Einstein. And Mesner. And Adler. And your own provided Chinese author.The fact is that, Weinberg did not prove Yang was wrong, but Yang proved Weinberg was wrong.
Again with your fantasies...If he saw Yang's demonstration, would be admired because Yang's demonstration was indeed higher level than he did
you say so indicates you still have a lot of misunderstandings, it is inpossible that I proved Yang wrong, this is ridiculousAs I said before: your own provided sources prove Yang wrong. That you choose to ignore that issue, doesn't make it go away.
4 and -8 are different, where the 4 should appear the -8 appears, isn't that a mistake?As I've asked you multiple times: point out where Weinberg makes a mistake. And Carroll. And Einstein. And Mesner. And Adler. And your own provided Chinese author.
I can't reach him. But I'm afraid it's harder to convince him than you. Planck seemed to have said that it is a waste of effort to let an expert accept new ideas unless they die.Have you contacted Carroll already? Since he's still alive, you should have no trouble convincing him, right?
