Mid-morning. You just got word that Linda is
checking out of Riverside Methodist Hospital after an overnight stay for
possible heart problems yesterday morning. She is okay, and did not have anything
serious. You are going up today (she will be at Kim’s) and you’ve decided to
turn the rental in at Columbus and drive the Honda back (as Linda is not up to
it and Carol is not allowed to drive yet). Carol is at physical therapy at the
community center. – Amorella
0938
hours. Always something. Linda gave us a scare yesterday. She came back from
Patti’s early and wasn’t feeling well. Paul got her admitted to Riverside so
they ran tests and discovered (thankfully) that is in good shape health wise.
It is about time to pick up Carol.
Late
afternoon. You are home from Kim and Paul’s – you had lunch at Local Roots in
downtown Powell then drove two miles west to drop off the Enterprise rental.
Pit stop at K/P’s then safely home. - Amorella
1710
hours. We had some rain on the way up and back but no problems. Glad to be
home. No doubt we’ll be watching last night’s PBS two-hour special review of
the first four seasons of “Downton Abbey “for Linda’s reviewing. Tomorrow the
girls want to go see Mission Impossible so that’s the agenda. Also, Kim
loaned Linda her Girl on the Train to read before she leaves for home on
Saturday, after that Carol and you are going to read it. – It is nice to have
our Honda Accord back. Actually, it is a more fun, better, more stable ride
than the new Chevy Sonic – amazing when you think it is ten years older –
everything but the gas mileage. The Sonic gets 31.2 and the Accord a 27.1
averaging mostly between 60 and 78 miles per hour on the freeway.
Presently you are at Kroger’s on
Mason-Montgomery Road. Yesterday, Amy King brought over peaches from the week
trip in Georgia. Carol and Linda have decided to make a peach pie either
tonight or tomorrow.
Earlier Doug sent you an article from the
Smithsonian about another possible end of the world/universe. You find it
interesting for what it says and what it doesn’t. No one knows of course, and
you find delightful humor in this aspect. – Amorella
1859
hours. We are home. A chain reaction that triggers the collapse of the
universe, now this would be something to write home about (if we knew where it
and we went). I find such articles interesting. I find most science
interesting, hypothesis, theory and otherwise. Here it is, and thank you Dr. John Douglas Goss for sharing.

Why Super-Small Black Holes
Haven’t Destroyed the Universe
And probably won't
By Marissa Fessenden

AUGUST 4,
2015
When the largest machine on the planet, the Large Hadron
Collider, first fired up, people got a little concerned that the high-energy
particle collisions scientists would produce might create mini black holes that
would gobble up the Earth. That didn’t happen, and researchers soothing the
feathers of a nervous public. But now theorists posit that a chain reaction
involving mini black holes could trigger a universe collapse, reports Adrian
Cho for Science.
Of course, the Sun, this planet and humans are all still here,
as is the rest of the universe, so this hasn’t happened. The question
intriguing physicists is: Why not?
The whole issue got more complicated with the discovery of the
Higgs boson, an elementary particle which provides a way for other particles to
have mass. The discovery of the Higgs boson means that the Higgs field probably
exists — an invisible energy field spread throughout the universe. (The Higgs
boson is actually a manifestation of that field.)
But given the mass of the Higgs boson researchers measured in
2012, and assuming that the current standard model of physics is correct, the
Higgs field might not be stable. It could be in a higher energy state. If
something triggers it to fall to the lowest energy state, it could cause the
vacuum of space to collapse. No, you did not misread — if the Higgs field falls
to its lowest energy state, the universe could simply disappear. (Those
intrigued or puzzled by this can check out an explanation of this vacuum decay by
Sabine Hossenfelder at Medium.)
Fortunately, that would require a lot of energy. As theoretical
astrophysicist Katie Mack of the University of Melbourne explains for The World
Science Festival’s blog if such a phenomenon could happen, it probably would
have already.
New calculations from theorists in the United Kingdom show that
mini black holes, which may exist, could trigger a bubble of space that does
fall to that lower-energy vacuum state. That bubble would ripple out and
consume the universe. The black holes would have to be small, Cho reports, but
it could still happen.
There’s another wrinkle in the question of why black holes
haven’t already laid waste to the entire universe — the mere fact of humans’
existence. Physicists may need to find some new physics to explain the mystery
of why tiny black holes haven't triggered this vacuum decay, researchers argue
in their paper for Physical Review Letters. After all, something must be
stabilizing the vacuum.
Theorists will debate whether this new argument is persuasive or
not, but in the meantime, there's no need to fear your abrupt end at the hands
of a very small black hole. After all, fretting probably won't be enough to
stop the collapse of an entire universe.

Later. Post. - Amorella
Time
for bed. You watched two of your programs after Carol and Linda went upstairs
to read on their books and go to bed early. – Amorella
2234
hours. I watched “Human” and skim-watched “Under the Dome”. “Human” had a plot
line I did not anticipate and with only one more episode for the season it
doesn’t look good for the good guys – still interesting. “Dome” has pretty much
run its course. Too easy to follow, even the cross framing back and forth
dialogue is not much, at least to me.
2246 hours. I enjoy seeing the 'humanity' jump out at me from the synths.
