A really big congratulations to you and the various teams, both related to the 
press conference, and the RC3 release.  You are, indeed, a very busy person.

Thank you for the huge contribution you and the various teams make to science 
and ham radio in general.

[wsjt-devel] Gravitational waves

[Joe Taylor]

Hi all,

This is my last post here for today, and it has little to do with 
WSJT-related software development.  But its topic has occupied much of 
my time for the past ten days -- and it has made me feel as excited as a 
youngster with a new scientific toy!  A few have asked offline if I 
would share some insider details, so here goes...


A press conference was held this morning at the National Press Club in 
Washington, D.C., to announce the LIGO/Virgo collaboration's detection 
of gravitational waves from a binary neutron-star coalescence event. 
The event occurred some 130 million years ago, in a distant galaxy 
called NGC 4993.  The gravitational waves traveled here at the speed of 
light, arriving at Earth on August 17, 2017.  Best of all, the collision 
event event was also detected in gamma rays, X-rays, ultra-violet, 
visible light, infra-red, and radio waves: nearly the whole 
electromagnetic spectrum!  You can watch the recorded press conference 
and get some idea of the scientific excitement here:

https://www.youtube.com/watch?v=aEPIwEJmZyE

You'll find a few more scientific details on the American Physical 
Society's web site: https://physics.aps.org/articles/v10/114 .


You might be interested in a sidelight relevant to ham radio: the 
"Hulse-Taylor" team mentioned in the APS article could equally well be 
called the "WB2LAV-K1JT" team.  In 1974, when Hulse and I did the work 
described in the APS piece, he was my graduate student.  Both of us were 
working in radio astronomy in part as a result of our boyhood interest 
in Amateur Radio.

Hi Joe,

Definitely a weak signal reception !

Like a  jigsaw, every new piece making the picture clearer.
All confirming each other.
It must feel good to see it growing.
Thanks for sharing.

My original career path was Physics, although ultimately I did not 
follow it, science is still with me.
I do enjoy trying to keep up with it all !

Best 73, David GM6BIG

The design sensitivity of Advanced LIGO is 10 times better than the 
previous detector, and the low-frequency end has been extended downward 
from about 40 Hz to 10 Hz.

The present sensitivity is not yet quite at the design level for 
Advanced LIGO, but it's getting close.  I do not think the observed 
signal would have been detected in any previous runs -- or if detected, 
would not have been considered sufficiently reliable for publication.

Advanced LIGO's sensitivity is such that the instrument is likely to 
observe dozens of compact binary coalescence sources per year.

Quite the contrary -- there are no implied assumptions involved here.

The LIGO-Virgo Collaboration has made a thoroughly extensive search for 
any other way that the observed signals could have been produced nearly 
(but not quite) simultaneously at two sites separated by some 3000 km.
The group has been extremely careful and thorough; their results can be 
taken at face value.

The discovery opens up a few new questions, which
I have not found any answers to on the internet.

Previously it was thought black holes preserve
all information (and entropy), and radiate it
back out over the lifetime of a black hole,
through Hawking radiation.

This event radiated out 3 solar masses worth
of energy as something other than Hawking
radiation.

Does this impact the preservation of
information and black hole entropy theories?

Does the black hole retain all the spin and
charge of those 3 solar masses worth of
radiated energy?

Does this place an upper limit on the
density (or information/surface area) of
a black hole?

Or, is the amount of information on the
surface area of a black hole (especially a
stellar mass one) so far from the maximum
limits that no black hole is truly dense
from this perspective?

As you can see from the questions above,
I am not qualified in the least in this
area. Just wondering some random things,
that the internet does not (yet?) seem to
have any answers to :)

Re: [wsjt-devel] Gravitational Waves

[Michael Black]

Is it "luck" or misinterpretation of what they are actually seeing?
There's an implied assumption in the paper that they are seeing gravity
waves as though there is no possible other explanation.
I'm reminded of what happened in the 80's when universities were claiming
galactic gamma sources but it turned out to be RORSATs.  Numerous papers
were published about it.
Is the team actually willing to say that their system detects absolutely
nothing but gravity waves?  Given all the noise on the detector they show
seems like there could be another explanation quite easily.
"chirps" are very popular in nature.  Even assuming they are seeing a
gravity wave is the only possible explanation two colliding black holes?
Are colliding black holes that common?

Hi Joe,

it seems such a large clean signal that I assume even the previous 
equipment might have detected it.

I had been following the press on this since the hints of something 
interesting a while back. Way back in '76-'78 when I was an 
undergraduate studying chemistry at Bristol University UK there was a 
gravitational waves detection experiment in the tower of one of the 
university buildings, I have a vague memory of attending a lecture about 
what they hoped to achieve and have followed progress as a passing 
interest since.

Perhaps they had a bit of luck to find a strong signal in the 16 days of 
fully analyzed data (taken between September 12 and October 20, 2015). 
But already in the discovery paper they show evidence of a second event, 
with about 1/3 the strength.  I think it likely that many more such 
events will be found in coming months.  We will soon know.

I'm in total agreement too. It is a totally outrageous comment. It is just
plain rudeness and bad manners. The poster should grind his axe [and maybe
something else ;-)] elsewhere.

I am fascinated by this advanced stuff even if I cannot understand it. I'd

Hi Joe,

it must be fantastic to have the lIGO team make direct observations here 
on Earth of what your previous work had measured indirectly!

Do you think they got lucky with their detection so soon after the 
equipment upgrade or are these observations going to become as 
commonplace as other types of astronomical observation?

Thank you very much. Is there a tentative release date for JTgrav? ;)

You are a little late to this party, as usual. A lot of the discussion about 
this phenomena, which doesn't have anything to do with WSJT (other than your 
ego that this is in fact your mailing list) has been happening all over so many 
mailing lists that your response is cluttering, off topic and a bit of 
braggadocio, even for you (who had nothing to do with the confirmation of an 
earlier theory). The most fruitful discussions can be found, in the mailing 
list world that many here might be interested in, located on the Time Nut's 
list. There may be other lists that cross boundaries that many here would find 
interesting, too. 

Next time, please confine your responses to those who asked you what you 
thought, because I know this list doesn't need a lot of off topic mail- your 
own rule, I think. But maybe you've changed it in midstream, like you do so 
many other things.

And while I'm wondering, since Steve did most of the work on the decoder 
recently- it will be his name first in the QEX article, right? Or do you 
actually believe you should be listed as the lead author for the article- even 
though you did nothing more than error checking?

Hi all,

After spending a most enjoyable week on the sunny Caribbean island of
St. Lucia, I'm home again.  Returning was quite a shock -- the
temperature here on arrival was 6 F.

Probably you heard last Thursday's announcement about the detection of
gravitational waves originating from a pair of colliding black holes,
some 1.3 billion light years away, in the southern sky.  This is a major
discovery in physics -- it opens a new window on the universe, if you
like.

Since I've already had off-list queries from several list members about
this announcement, I'll share a few links to some of the essentials:

Full press release from the LIGO (Laser Interferometer Gravitational

The actual detected waveform of the black-hole collision, presented as
an audio clip you can listen to:

In case you're interested in more details, I've posted a copy of the

Re: [wsjt-devel] Gravitational Waves

[Chase Turner]

Joe,

You are a little late to this party, as usual. A lot of the discussion
about this phenomena, which doesn't have anything to do with WSJT (other
than your ego that this is in fact your mailing list) has been happening
all over so many mailing lists that your response is cluttering, off topic
and a bit of braggadocio, even for you (who had nothing to do with the
confirmation of an earlier theory). The most fruitful discussions can be
found, in the mailing list world that many here might be interested in,
located on the Time Nut's list. There may be other lists that cross
boundaries that many here would find interesting, too.

Next time, please confine your responses to those who asked you what you
thought, because I know this list doesn't need a lot of off topic mail-
your own rule, I think. But maybe you've changed it in midstream, like you
do so many other things.

And while I'm wondering, since Steve did most of the work on the decoder
recently- it will be his name first in the QEX article, right? Or do you
actually believe you should be listed as the lead author for the article-
even though you did nothing more than error checking?

Thanks,
Chase
