А гравитационные волны.... Ну я пока, кажется не нашел.
Если их так и не найдут, это будет посильнее отрицательного результата Майкельсона-Морли. Мне сдается. что это именно так. Хотя, я могу ошибаться. Гравитационная волна может оказаться эфирным ветром физики ХХ века.
Прекрасненько... А вот, что Вы, Bob, можете рассказать нам о широко разрекламированных косвенных свидетельствах Hulse and Taylor по потерям в двойном пульсаре?
Вот ниже John Baez вещает о "Gravity waves detected in the local region"... >;^)
"the main piece of indirect experiment is the experiment of Hulse and Taylor on
the decay of the orbit of a binary pulsar."

What's the "JSD"? Could you give me a reference for this article?
I'm worried that you or they may be mixing up "gravity waves" and
"gravitational waves". These are completely different phenomena!
1) A "gravity wave" is a wave in the earth's atmosphere, analogous
to a large wave in the ocean, in that the restoring force that
keeps the waves going is the earth's gravity. More generally
one can speak of a gravity wave in the atmosphere of any planet,
or for that matter in the atmosphere of thus sun.
Gravity waves are comparatively easy to study. For some pictures
of gravity waves in the earth's atmosphere see:
http://cimss.ssec.wisc.edu/goes/misc/980319.htmlhttp://whirlwind100.nssl.noaa.gov/~spc/coolimg/gwavepix.htm2) A "gravitational wave" is a wave in the spacetime metric,
predicted to exist by Einstein's theory of general relativity.
There is no direct evidence for their existence; the main piece
of indirect experiment is the experiment of Hulse and Taylor on
the decay of the orbit of a binary pulsar. Currently people
are building a number of devices in order to detect gravitational
waves.
For the LIGO project to detect gravitational waves, see:
http://www.ligo.caltech.edu/ Now, the situation is slightly confused by the tendency for
people to colloquially call gravitational waves "gravity waves",
but the important thing is that we have two utterly different
phenomena here.
I can easily imagine gravity waves in the Sun's atmosphere being
relevant to sunspots. However, I wouldn't get excited about this
as "direct evidence of gravity waves in our local region", unless
I happened to live on the Sun, because we have plenty of easily
visible gravity waves much closer to home! - namely, in the Earth's
atmosphere. So I have trouble imagining that that JSD article
is trying to say, unless they are using "gravity wave" to mean
"gravitational wave".
On the other hand....
I cannot imagine gravitational waves being relevant to sunspots
or the solar cycle! First of all, gravitational waves are far
too weak to have any noticeable effect. Secondly, if they did
have an effect, it would have to be the best-kept secret on the
planet, because lots of people are spending millions of dollars to
detect gravitational waves, and all these people are under the
impression that gravitational waves have not yet been seen.
So either way, I don't understand what this quote is trying to
say."
