I guess its about time again for my regular question re experimental
results from the LIGO observatories. I just checked some of their sites
and papers and unless I missed it they STILL after several years do not
have a single definite detection of a "Gravitational Wave". This is
despite the observation of a very powerful, cosmologically close GRB
,which, so Physcists have told me, should be a powerful source of
Gravitational radiation.

...assuming the GRB was produced by a certain process. The non-
observation of the expected gravitational waves ruled out the process.
What's so hard about that?

You may want to investigate how slow it has been in investigating the
LIGO output. The data set S3 is the most recently analyzed set, and we
are on S5. We have no way of knowing if anything has been seen or not
until the analysis is complete.

How long are we expected to wait and maintain these expensive and
complex sets of apparatus before it becomes clear that either this
radiation does not exist, or, even more likely, LIGO is as incapable of
detecting it as an optical telescope with lead lenses.

agreed,
last I heard they had two orders of magnitude (powers of 10) to go in terms
of increasing sensitivity and decreasing noise.



Leave physics to those who understand what is going on.

A significant amount of money was invested into building the LIGO
facilities, and the money for Advanced LIGO has already been budgeted.

because the first one was ill designed.


The amount of money it takes to operate the facilities is absolutely
tiny compared to the ~1 billion USD/day for the American sandbox
adventures.

Are you yelling proportionally louder at the waste of money at us
being in Iraq, or are science projects the only thing catching your
ire?

What I would like to know is: just how strong is the theoretical and
experimental basis for the present accepted theories involving this
radiation?

www.google.com "how to use google"

A Nobel was awarded to Hulse and Taylor regarding a subject that is
relevant.

and so was Al Gore, inventer of Global Warming AND the Internet.


Have those involved already modified their models in the light of the
non results from LIGO?

Yes. Which is the whole fucking point.

they havent got below the noise level yet.


I'm old enough to have been involved in science back in 1972 when the
first alleged detection of "Gravity Waves" took place but so far it
still seems even more of a Chimera than Fusion power.

Things have progressed just a little since Weber's aluminum cylinders.

and still have a long way to go
