Kim confirmed that M/I is working on the
blueprints. Wednesday you are meeting Kim at Roush Honda in Westerville at ten
when she leaves her Odyssey for service. You and Carol will pick her up and go
see a model of your house under stick construction at a similar M/I development
in Dublin. After which you will have lunch then drop her off at Roush's to pick
up her car in time for her to pick up the boys at school and take them to their
Jujitsu classes after school. - Amorella
2108 hours. Another day and I don't really remember what we did. This is
two days in a row. I cannot remember using the computer or watching . . . we
did watch two programs this afternoon after picking up a usual foot-long Subway
sub and bringing it home for sharing. We watched "Madam Secretary"
and "NCIS.LA" from last night. I took a nap, had half a sandwich for
supper and watched NBC and ABC News. There was a good science article on BBC
that I shared on FB. Real news.

Einstein’s waves
detected in star smash
·
16 October 2017
They have confirmed that such
mergers lead to the production of the gold and platinum that exists in the
Universe.
The measurement of the
gravitational waves given off by this cataclysmic event was made on 17 August
by the LIGO-VIRGO Collaboration.
The discovery enabled telescopes
all over the world to capture details of the merger as it unfolded.
David Reitze, executive director
of the LIGO Laboratory at Caltech in Pasadena, California, said: "This is
the one we've all been waiting for."
The outburst took place in a
galaxy called NGC 4993, located roughly a thousand billion, billion km away in
the Constellation Hydra.
It happened 130 million years ago
- when dinosaurs roamed the Earth. It was so far away that the light and
gravitational waves have only just reached us.
The stars themselves had masses
10-20% greater than our Sun - but they were no larger than 30km across.
They were the crushed leftover
cores of massive stars that long ago exploded as supernovas.
They are called neutron stars
because the process of crushing the star makes the charged protons and
electrons in the atoms of the star combine - to form an object made entirely of
neutrons.
Such remnants are incredibly
dense - a teaspoonful would weigh a billion tonnes.
In the landscaped campus of one
of the laboratories that made the detection, a fountain sprays jets of water
skyward which are then pulled back down by gravity, sending ripples across the
crystal clear pond.
The LIGO detector, sitting
incongruously in the vast woodland of Livingston in Louisiana, was designed to
detect the gravitational ripples across the Universe created by cataclysmic
cosmic events.
Since it was upgraded two years
ago, it has four times sensed the collisions of black holes.
Gravitational waves caused by
violent events send ripples through space-time that stretch and squeeze
everything they pass through by a tiny amount - less than the width of an atom.
The LIGO lab at Livingston
consists of a small building with two, two-and-a-half-mile pipelines stretching
out at right angles. Inside each pipe is a powerful laser accurately measuring
any change in its length.
I walk along one of the pipes
with Prof Norna Robertson, a Scot who used to work at Glasgow University - and
more recently helped to design the instrument's detection system.
Prof Robertson's work has helped
the LIGO-VIRGO Scientific Collaboration to make the first ever detection of the
gravitational waves given off by the collision of two neutron stars.
"I'm really thrilled about
what we have done. I started off as a student in Glasgow 40 years ago working
on gravitational waves. It's been a long long road; there have been some ups
and downs but now it's all come together," she told BBC News.
"These last couple of years,
first of all with the detection of black holes mergers and now a neutron star
merger, I really feel we are opening up a new field, and that's what I wanted
to do and now we've done it."
The detection enabled 70
telescopes to obtain the first ever detailed pictures of such an event.
These show an explosion 1,000
times more powerful than a supernova - a burst called a kilonova.
§ Gravitational waves are a prediction of the
Theory of General Relativity
§ It took decades to develop the technology to
directly detect them
§ They are ripples in the fabric of space-time
generated by violent events
§ Accelerating masses will produce waves that
propagate at the speed of light
§ Detectable sources ought to include merging
black holes and neutron stars
§ Ligo/Virgo fire lasers into long, L-shaped
tunnels; the waves disturb the light
§ Detecting the waves opens up the Universe to
completely new investigations
Researchers had suspected that
this huge release of energy leads to the creation of rare elements, such as
gold and platinum.
Dr Kate Maguire, from Queen's
University Belfast, who analysed the collision's burst of light, said that the
theory was now proven.
"Using some of the world's
best telescopes, we have discovered that this neutron star merger scattered
heavy chemical elements, such as gold and platinum, out into space at high
speeds.
"These new results have
significantly contributed to solving the long-debated mystery of the origin of
elements heavier than iron in the periodic table."
Dr Joe Lyman, of the University
of Warwick said described the observations as "exquisite".
"They tell us that the heavy
elements, like the gold or platinum in jewellery are the cinders, forged in the
billion degree remnants of a merging neutron star."
Improvements coming
It was also direct confirmation
that short bursts of gamma-ray radiation are linked to colliding neutron stars.
By combining information from
gravitational waves and the light collected by telescopes, researchers also
used a new technique to measure the expansion rate of the Universe. This
technique was first proposed in 1986 by the University of Cardiff's Prof
Bernard Schutz.
Prof Stephen Hawking of Cambridge
University told BBC News that this was "the first rung of a ladder"
for a new method of measuring distances in the Universe.
"A new observational window
on the Universe typically leads to surprises that cannot yet be foreseen. We
are still rubbing our eyes, or rather ears, as we have just woken up to the
sound of gravitational waves," he said.
Prof Nial Tanvir, from Leicester
University, uses the VISTA telescope in Chile.
He and his colleagues started
searching for the neutron star collision as soon as they heard of the
gravitational wave detection.
"We were really excited when
we first got notification that a neutron star merger had been detected by
LIGO," he said. "We stayed up all night analysing the images as they
came in, and it was remarkable how well the observations matched the
theoretical predictions that had been made."
LIGO is now being upgraded. In a
year's time it will be twice as sensitive - and so will be able to scan eight
times the volume of the space.
The researchers believe that
detections of black holes and neutron stars will become common place. And they
hope that they will begin to detect objects that they currently cannot even
imagine and so usher in a new era of astronomy.

hours. The article is awesome because it represents new knowledge; it is always
cool to be able to read or hear about new scientific knowledge.
During most your conscious life your fondest
secret wish was having contact with either real aliens or real angelic
creatures. - Amorella
2131 hours. That explains a lot. It was a secret wish, a hope really. It
probably was a product of my thinking (when I began delivering the morning
newspaper at ten years of age - "The
Citizen", then "The Citizen-Journal". As I've mentioned before,
I loved to get up early enough to read the paper before I delivered to my
customers in Minerva Park. I wanted the news first. Communicating with aliens
was my wish. Later, angels, after I assumed that if they were real too then it
might be possible to communicated with one of them. Ha. Basically, Amorella,
you are a wish fulfillment. (2138)
Ironically, one you did not ask for and one
you earned unconsciously under conscious existential circumstances. - Amorella
2141 hours. That's the rub, isn't it.
Yes, indeed, boy. That's the rub. - Amorella
2143 hours. We live in such a world this circumstance can exist in my
head as a once real circumstance.
No one can say for sure. "Am I, the
Amorella, a real Angel?" Do you deny that I am, boy?
2147 hours. I cannot, but I do not believe you are. After all these
years, all these words, I cannot deny, but then I cannot define what a real
angel would be. As far as I am concerned no one else can define what a real, a spiritual
angel, is either.
You were interrupted by your favorite black
and white cat, Jadah. She climbed up and waited until you put the computer
down, and your head pillow and your lap pillow. After which, she climbed upon
your left arm, sat comfortably, and purred contentedly, until she jumped down
and left the bedroom. Carol is sitting on the bed reading your latest
"Consumer's Report" while listening to a TV show. Imagination drifts
away in such a scene. The ceiling fan is set on low, you hear what sound like
singing crickets in your head. This is tinnitus. A problem you have had since
you were five and lit a firecracker near your left ear. You thought it was a
dud. - Amorella
2209 hours. I did. I dropped it in a backyard fire can burning trash. It
didn't have a fuse. I figured it was a dud. I was surprised when it blew. My
ear was less than a foot from it. Pretty stupid. Both ears ring from time to
time. I remember I was told that the sounds weren't real, that other people did
not hear the ring (or other noises). The sounds were in my head. Even though
the sounds appeared to be real to me they were not real. Later, angels were
like that, sometimes real to me, but not to others. I had no trouble balancing
this out. I was making it up without knowing I was doing so. That is, my ear
was making up the noises. I did not do this on purpose. What else could I do
but just live with it, like everyone else has problems they have to live with.
You adapt. That's what people do, that's what I did and still do. So much for
aliens, angels and other wishes. Who would have thought I would live so long. (2219)
