Revision as of 18:50, April 9, 2007

Great article

1) Superb avoidance of difficult science in a scientific article. Best not to be confusing. 2) Nice attention on Eddington rather than the theory itself. 3) Good mind reading regarding Eddington's dreams. 4) Nice work ignoring the facts about things that have been inventing using GR such as GPS

And rather than simply be sarcastic, I will work on a better article over the weekend. One that actually discusses the science.

Special and general relativity

This article seems to combine the two. They are different ideas and need to be distinguished. JoshuaZ 19:21, 24 February 2007 (EST)

Agreed. Separate articles would make more sense. I don't have time to do the necessary work right now, but if no one else does it I'm sure I'll get to it eventually. Tsumetai 10:11, 25 February 2007 (EST)
If someone will split the pages, I'll help flesh them out.--ZLewis 10:42, 1 March 2007 (EST)

Moral Relativism line needs to go.

I have never heard anyone advocating moral relativism use either of the theories of relativity to do it. Actually, the only people who I've ever heard that from are relativity deniers like Fred Hutchison. Not only does that show a grave misunderstanding of the scientific theory, but also a misunderstanding of the phrase "moral relativism". In any case, you can't draw moral implications from scientific theories. When someone says that Einstein's theory of relativity implies some kind of moral relativism, they're really saying "The geometric theory of gravity allows me to internalize my moral decisions".

That line is ridiculous and irrelevant, and needs to disappear.

I don't like it at all in its present form, but the word "relativity" is thrown around casually quite a lot and there might be justification for a section with a title like "what relativity is not."
E.g. Scott Adams, author of the Dilbert comic strip, says "Einstein’s great insight was assuming reality was not fixed, and that everything was relative to the observer" and goes on to say "I have extended that thinking to people..."
I think using Scott Adams as a reference or a jumping-off point for discussion really constitutes holding one's self to a dismally low standard. He's posted his own theories of physics to his blog a few times, freely admitting that he knows they're wrong and that he just takes pride in the fact that the layman can't successfully challenge them. In all honesty, moral relativism is a perfectly valid subject for an article, but it doesn't have anything to do with physics other than an unfortunate overlap of words and definitions in English. Putting this section in just makes the authors look like they're bristling for a fight. Willforpresident 21:25, 7 March 2007 (EST)
What follows is interesting if not very profound, but dragging Einstein into it is not helpful.
It just goes to show the value of jargon. When scientists give something a simple name like "relativity," people assume they understand it and misapply it. I'm just thankful that people aren't very familiar with mathematics or we'd be hearding about crop circles in Galois fields. Dpbsmith 12:50, 25 February 2007 (EST)
I like the "what relativity is not" idea. Might be worth pointing out that relativity in physics didn't start with SR; there is such a thing as Galilean relativity, after all. Tsumetai 12:57, 25 February 2007 (EST)

This line must go. It is not relevant to the article. Have a disambiguation page for relativity. The citation is completely incorrect. The website http://www.moralrelativity.com/about1.html says nothing about general relativity influencing moral relativity. This article says 'Relativity has generated a huge following by advocates of moral relativism,' but the website http://www.moralrelativity.com/about1.html does not make any mention of this statement, therefore it is improperly cited. Citations are supposed to support claims, and this one does not. (Read the website for yourself). Also, just because relativity is a homophone in this case doesn't mean it belongs in an article of the (general) theory of relativity. Please make a disambiguation page because this is clearly in the wrong place.

I removed the moral relativity part from this article and placed it in a new article called Moral relativity. Relativity here is clearly just a homophone, and moral relativity is irrelevant to special or general relativity. To illustrate my point, see http://dictionary.reference.com/browse/relativity. Relativity in physics has a special meaning. Teji 00:38, 5 April 2007 (EDT)

Folks, moral relativism is a big reason for the political support of types of relativity. It's obviously relevant to this article, and the above criticism only reinforces the need to include a reference. We can debate how to say it, but censorship is not an option here. Go to Wikipedia for that.--Aschlafly 01:31, 5 April 2007 (EDT)
Okay, then that can go into the Moral relativity article, which now exists. There is no support for your claim. Neither is there a need for political support for a scientific theory. The way you describe it, moral relativity references this theory of relativity, not the other way around. The theory of relativity neither relies on moral relativity in any explanation of it or needs it to be mentioned for a complete treatment of the theory, and therefore it is inappropriate to add it here. I direct you again to the dictionary http://dictionary.reference.com/browse/relativity in order to clarify that relativity in this sense has specific meaning in the domain of physics, and arbritrary theories that share the word are not in this domain nor are related in any concrete way, simply being homophones. Teji 18:40, 5 April 2007 (EDT)


Someone added more about the moral relativity bit, so I put it in the right place: in the article on Moral relativity. The section says, "Advocates of moral relativity seized on the theory of relativity to legitimize their views," which is about moral relavitity and how they use the theory of relativity, not how the the theory of relativity involves moral relativity. I challenge the writer again to find a work on the physics theory that metions moral relativity at all. Just because a page mentions the theory of relativity does not make it a legitimate part of the theory itself, and as such, does not belong in this article. If anything, the Moral relativity article should make a link to this article, not the other way around. I am not sure the agenda here, but it seems that someone would like to promote moral relativity by attaching it to unrelated articles. Please add your information to the correct article in the correct place. Again, here is the link: Moral relativity. Go crazy. Teji 14:42, 6 April 2007 (EDT)

ASchlafly, you added the line "Advocates of moral relativity seized on the theory of relativity to legitimize their views" and gave a citation afterwards. If you read the page that you cite, you will see that the author merely uses Special Relativity to demonstrate how moral relativism works. He does not "seize" on the theory and does not use it to "legitimize" his view. Can you find a better source please? (or remove the sentence)

I can't tell who or when this comment was made, because it lacks the signature (use the signature button above). But I will look for more sites about to support my statement, which should be easy to find. Frankly, I've never heard anyone doubt the statement.--Aschlafly 20:07, 8 April 2007 (EDT)


Perhaps you've been listening the wrong people. No reputable explanations of relativity mention moral relativity. Find a reputable one. Don't look for moral relativity explanations that include physics relativity, because that information belongs in Moral relativity, not here. You are researching the wrong topic. Repeat: look for information about the physical theory of relativity and see if you can find one that mentions moral relativity (not pages that talk about moral relativity and mention physical relativity). Furthermore, anyone can set up a web page and say whatever they want, so web pages are generally not a very good resource (unless it's the physics department website at MIT, for instance, because it has credibility in this field). You should find reputable scientific texts. And, please, stick the topic at hand: physical science topics needs physical science resources. There is ample room in the Moral relativity article to discuss. In fact, I'm surprised you aren't contributing more to that article (especially compared to how much you try add to in this article), since you seem to be very interested in the topic and are more knowledgable about it than physical relativity. Teji 13:08, 9 April 2007 (EDT)

not "attributed" to Einstein.

isn't just "attributed" to Einstein. When someone says "attributed", they typically mean that someone is given credit for an idea somewhat apocryphally. Einstein obtained the relation in his Zur Elektrodynamik bewegter Körper, in which, from the Lorentz transformations, he obtained the relations:

and then, as :

.

And these bizarre polemics are undermining what little credibility this encyclopedia has. Sneering at Einstein and glorifying the contributions of Ponicare makes all of the sense of arguing over whether Leibniz or Newton invented calculus, particularly since there are very palpable differences between Einstein and Ponicare's treatments of the subjects. And, I see someone has removed the "there is no evidence for the general theory", but I'm sure it will be back by this afternoon. That's ever weirder -- how on earth can someone say that "there is no evidence" and then, in the same article, link to black holes?

I'm not going to go back to that article on Dirac Notation to fill up all of those links with articles until I'm sure one of the administrators isn't going to replace them with accusations of quantum mechanics being tantamount to the Kabbalah, or something equally stupid. (unsigned)

It is a fact that Poincare published E=mc2 and most of the rest of special relativity before Einstein. Maybe you think that this is sneering or glorifying, but it is a fact, and there is no serious dispute about it. RSchlafly 20:17, 9 March 2007 (EST)
This is true, but what Poincare described was a specific case of E=mc2. An experimental result showed that there was momentum when a body ejected EM radiation, but the mass was unaccounted for. Poincare described the mass of the EM as m=E/c2. Einstein derived this formula from more fundamental assumptions, the speed of light is absolute, etc. This is why his work is so famous. In fact, in all of science, nothing belongs to any one person, even though they may get credit, but are supposedly discovered. Also do not forget that Einstein also published General Relativity.
Furthermore, while Poincare regarded it as superfluous, scientists of the day were still trying to work with the luminescent ether. Einstein's work proved this unnecessary.
Again this is a lesson in science. We are always trying to compress and refine our science. Einstein, while he of course drew on other's work and surely knew of Poincare's m=E/c2 paper, his work was more refined and simpler, deriving many principles, Poincare's and new ones, from a few fundamental principles. Poincare published a paper about a month before Einstein with similar work, but in science, no one person makes a discover. Don't forget, Newton has his Hooke. But like Newton, it was Einstein's derivation and formalizations that worked better. (unsigned)
Yes, Poincare described was a specific case of E=mc2, but so did Einstein. Einstein did not foresee particle annihilation or nuclear energy. Poincare's description of the ether as superfluous is nearly identical to Einstein's.
How was Einstein's work on special relativity any more refined, simpler, or better working? I deny this. Poincare showed a better understanding of the theory than Einstein. RSchlafly 14:16, 23 March 2007 (EDT)
Don't ask me, ask Lorentz. http://ia331314.us.archive.org/2/items/theeinsteintheor11335gut/11335-h/11335-h.htm
OK, I looked at your link. The first thing I saw was a claim that the 1919 eclipse proved the General Relativity. We now know that eclipse proved no such thing. So much for the credibility of that link.
The link does show that Lorentz and Einstein were patting each other on the back. That's fine, but it suggests a lack of objectivity towards the odd man out, Poincare. This dispute cannot be resolved by self-interested party, obviously.--Aschlafly 01:29, 5 April 2007 (EDT)
Can't get much more credible than a publication by Lorentz on Gutenberg, bud. It may be dated, but it is closer to the date of Einstein's work. As far as I see you, you have the burden to prove your claim as much as everyone else has to support the opposite claim. Where is your evidence of credible sources? Teji 18:45, 5 April 2007 (EDT)

Old version

I was just looking at an old version of this page, and the absurdity of the "scientific" claims made, combined with the low quality of the writing and blatant inaccuracies, make the article, quite frankly, almost intellectually offensive. I realize that this has since been rectified, but if this is the quality that is to be expected of Conservapedia articles, then I do not blame those who dismiss it as a failed attempt. Geekman314(contact me) 15:12, 9 March 2007 (EST)

be specific in your statements if you expect a response.--Aschlafly 19:04, 9 March 2007 (EST)

I find the content reverted to in the above edit to be quite disturbing.

  • The General Theory of Relativity does not reject Isaac Newton's "God-given" theory of gravitation, it simply provides an explanation for why it functions.
that was obviously vandalism.--Aschlafly 19:04, 9 March 2007 (EST)
  • It is most certainly not a problem that the General Theory of Relativity is based upon mathematics as opposed to empirical evidence, as seems to be insinuated by this version.
mathematics is mathematics, and unless there is empirical evidence it is not science.
Mathematics describes physics. Geekman314(contact me) 22:33, 9 March 2007 (EST)
  • Albert Einstein's work did contribute to the development of the nuclear bomb. E=mc2 describes the duality between matter and energy, the principle upon which the nuclear bomb, and all other nuclear devices, functions.
nope. E=mc2 is a statement of relativistic effect, not atomic power.
Yes, but the mass lost in the nuclear reaction is converted to energy, which is the fundamental power of the weapon. Geekman314(contact me) 22:33, 9 March 2007 (EST)
  • "Nothing useful has even been built based on the theory of relativity." Sure, sure… nuclear power plants aren't useful at all, are they? GPSs aren't useful at all, are they?
GPSs are useful, but they weren't built using General Relativity.
Without realativity describing gravitation redshift, the timing for the GPS satelite would be off by about 45 microseconds/day. Further reading on the matter at http://www.astronomy.ohio-state.edu/~pogge/Ast162/Unit5/gps.html --Mtur 19:08, 9 March 2007 (EST)
I think Lorenzian relativity accounts for the GPS time dilation more precisely. But that isn't really my point. The GPS clocks are updated based on communications between the satellites and ground stations, not based on any theory. If you claim that GPS is built based on relativity, then you should be able to prove your case with an historical reference. No such proof exists.--Aschlafly 20:39, 9 March 2007 (EST)
That observation does not support the false claim that GPS is based on General Relativity. Other theories predict a dilation of time, and satellites are obviously synchronized based on communication, not theory.--Aschlafly 19:11, 9 March 2007 (EST)
No, they have GR corrections built in. Tsumetai 19:15, 9 March 2007 (EST)
Can you please cite an alternate theory that accounts for the time dilation experiecned by the GPS satelites along with the math that matches that of relativity? --Mtur 19:17, 9 March 2007 (EST)
  • "Most conservatives are skeptical since science is supposed to be about finding proof before a theory becomes a fact, not after." And where are the statistics that show this?
Don't know who wrote that statement, but it's a correct statement of what science means.
I was refering to the claim that "most conservatives are skeptical since science…" (emphasis added) Geekman314(contact me) 22:33, 9 March 2007 (EST)
  • Gravitons are not predicted by general relativity; much to the contrary, the two have not been reconciled.
  • It is currently believed that space does indeed have curvature, what is described as "negative" curvature, giving it a saddle-like shape overall, but curvature nonetheless.

The denial of demonstrated principles because they do not coincide with your worldview is not scientific, it's purely reactionary nonsense. I'm not impressed by Examples of Bias in Wikipedia citing Wikipedians taking issue with this as a "bias". Geekman314(contact me) 16:11, 9 March 2007 (EST)

OK, fine, no one is trying to impress you. The Wikipedia entry was biased and demonstrably false, as explained in Bias in Wikipedia.--Aschlafly 19:04, 9 March 2007 (EST)
Oh, and I mean no offense to Aschlafly. Although I do not necessarily agree with all his views, I do not wish to disparage him, and I recognize his value as a contributor. I've reconciled with him on this issue, and want to make clear that I do not mean this comment as an attack. Geekman314(contact me) 22:44, 9 March 2007 (EST)
I just realized that I had somehow managed to fail to see that Aschlafly's edit was a simple revert to a previous version. I don't necessarily agree with the decision, and I don't retract the points with which I take issue, but Aschlafly is not responsible for the content, and I'm sorry for insinuating that he was. I've changed some of my comment to reflect the fact that the edit was simply a revert. Geekman314(contact me) 23:29, 9 March 2007 (EST)

Merge with draft

There is a draft for this article here. Surely it's about time these two were merged together or at the very least decide which one is to be continued. I will continue to work on Theory of Relativity/draft as I feel it is a much clearer article. What does everyone else think? MatteeNeutra 07:33, 8 April 2007 (EDT)

Your draft article has some great stuff in it. Would you like to merge it into the main article now? However, please do not delete anything from the main article as part of the merge. Thanks and a good Easter to you.
By the way, it appears that relativity is taught in college without using the concept of relativistic mass. But let's go with your relativistic mass as you wrote it.--Aschlafly 20:06, 8 April 2007 (EDT)

This isn't Wikipedia

Teji, don't delete facts here that liberals don't like. This isn't Wikipedia.--Aschlafly 13:02, 9 April 2007 (EDT)

Please read my explanation above. I don't think anyone likes unsourced information that is in the wrong topic. Please contribute to Moral relativity. I had to create that page while someone was adding information about it to the this topic. Teji 13:10, 9 April 2007 (EDT)
Furthermore, that link is about moral relativity, not special relativity. It belongs in Moral relativity. It is shocking that someone so interested in that topic didn't even think to make the article. In fact, I started that article! Teji 13:12, 9 April 2007 (EDT)
Here is what I said above in case you didn't catch it: No reputable explanations of relativity mention moral relativity. Find a reputable one. Don't look for moral relativity explanations that include physics relativity, because that information belongs in Moral relativity, not here. You are researching the wrong topic. Repeat: look for information about the physical theory of relativity and see if you can find one that mentions moral relativity (not pages that talk about moral relativity and mention physical relativity). Furthermore, anyone can set up a web page and say whatever they want, so web pages are generally not a very good resource (unless it's the physics department website at MIT, for instance, because it has credibility in this field). You should find reputable scientific texts. And, please, stick the topic at hand: physical science topics needs physical science resources. There is ample room in the Moral relativity article to discuss. In fact, I'm surprised you aren't contributing more to that article (especially compared to how much you try add to in this article), since you seem to be very interested in the topic and are more knowledgable about it than physical relativity. Teji 13:08, 9 April 2007 (EDT)
I find it interesting that when you cannot support your information you resort to name-calling and statements about wikipedia. Does this site want credible and accurate information or information with an agenda? Because if it is the latter, please make a statement to that effect in your policy pages, or would that make this website too credible and accurate? Teji 13:16, 9 April 2007 (EDT)

Teji, the statement does not claim that the theory of relativity supports moral relativity, but merely that supporters of moral relativity seized upon the theory of relativity to justify their views. "Advocates of moral relativity seized on the theory of relativity to legitimize their views.[3] Historians such as Paul Johnson wrote about how the theory of relativity caused a sea change, justified or not, in 20th century thought." That statement is correct and should not be deleted. Read it, and reread it, and only comment further here if you can provide something that specifically refutes that statement. Thanks.--Aschlafly 13:18, 9 April 2007 (EDT)

It is in the wrong place. The statement is clearly about Moral relativity. This statement is also correct: Jesus is God, does it belong in this article? No. Here is another correct statement: morality is "what is the good" and ethics is "how do I practice it" from the moral relativity site. Does it belong in this artcle? Certainly not. Teji 13:21, 9 April 2007 (EDT)
Correctness is not enough. There also must be accuracy. Information about Moral relativity belongs in that article. Teji 13:22, 9 April 2007 (EDT)
Maybe you should change the title to just "Relativity". RSchlafly 14:03, 9 April 2007 (EDT)
Okay, how do I do that? We could also make a disambiguation page, but I don't know how to do that either. Teji 14:28, 9 April 2007 (EDT)

Why was quote about Dicke removed?

I added this quote about the Francis Dicke's theory. Aschalfy, why did you remove it without any comments? It is from the same time magazine article that is already cited in this article. It clarifies why Dicke's theory is less professionally accepted! Please read the article yourself. It shows that Einstein's theory was closer than Dicke's.

But the J.P.L. experimenters reduced the margin of error to 4% or less by locating the distant spacecraft within 100 ft. of their actual position. Thus, when they calculated that the signal to Mariner was slowed down by 204 millionths of a second on its round trip, they dealt the Brans-Dicke theory a sharp if not decisive blow. Their measurement was only 4 millionths of a second off the Einsteinian prediction, but 18 millionths of a second off the Brans-Dicke figure. http://www.time.com/time/magazine/article/0,9171,943324,00.html

This is the same article that that is cited for the statement Physicist Robert Dicke of Princeton University was a prominent critic[7]. The same article that shows why Robert Dicke's theory is not accepted among scientists. Dicke suffered not just because he criticized Einstein's theory, but also because his theory was not as accurate. Teji 14:41, 9 April 2007 (EDT)

Time magazine is not an authority on whether Dicke's theory is better than Einstein's. Our rules are very clear not to cite journalists as authorities beyond their expertise. A scientific citation that I added shows that Dicke's theory is held in high regard to this day.--Aschlafly 14:50, 9 April 2007 (EDT)
