Earlier
this morning you were are Dr. M's having your skin sac emptied of old stuffing and refilled
with anti-bacterial stuffing. You have to return Wednesday morning for
expunging the old stuffing and refilling one more time. After noon you drove to
Mike's for a car wash, stopped at Piada's Street Italian for two salads to go,
stopped at McD's for two dollar drinks to go. Presently you are sitting near
the north center of Rose Hill Cemetery under the shade. You had your small
salads and now Carol is on page eight of David Baldacci’s The Last Mile.
The line of school buses is going south (in your mirror) on Mason-Montgomery to
pick up high school students at two-twenty-five. - Amorella
1415 hours. We are appreciative for
living so long; beyond schedules other than those of our own making. Retirement
has been good to and for us. The leaves are out on all the trees I can see from
here. We have never had such an early Spring before that we can remember. I
have these last two chapters on the left of the desktop. Time to work on
chapter twenty. (1420)
Let's
go to it. - Amorella
1441 hours. We have cleaned up the basics. Now to add the
Soki's comments on what's going on at a deeper level? Is he angel-like here or
just adding commentary like the Stage Manager in Our Town? (1443)
You
are home. Angels are another topic to discuss. It would not be right to leave
them out. Why not do this in the next chapter. - Amorella
1514 hours. Amorella, this is almost too much. I love
thinking about souls and hearts and minds and angels too. Must be too many
faery stories when I was a kid. I loved wondering about stuff and how it is
that such things 'might' really exist. I cannot remember when I did not think
on such things. One of the questions that came up probably in junior high -- 'How
would you know if there was an angel in the room?' A mind you have (brain) but
how would you know if you had a soul or if you didn't have one? A heart is
usually more discernable but not always. People can demonstrate that they have
a good heart for instance but it might be for a selfish intent. These things
are not so easy to know. I think even if you are machine based or bio-machine
based like in the film Ex Machina. (1524)

You
had make-shift suppers, watched NBC News, a "NCIS.LA" and a

are noting an article from tonight's Quora. Here it is. - Amorella

How do tachyon
particles comply with relativity if nothing can travel faster than light?

Who told you that nothing can travel faster than light? In
principle, even you can make something travel faster than light if you had a
powerful enough laser pointer and you can shake it rapidly enough. If you aimed
it at the Moon and wiggled it back-and-forth 50 times a second, the red dot
would be zipping across the lunar surface faster than the speed of light. And
this is perfectly consistent with both the special and the general theory of
relativity.
So let’s take a look at what the theory actually says. It tells
you that the vacuum speed of light is invariant. Which is to say that
its measured value does not depend on the speed of the observer. All observers
will measure the same vacuum speed of light. No matter how rapidly you are
chasing a beam of light, it will still be escaping you (as measured by you) at
the same vacuum speed of light.
One consequence of the theory is that there is no continuous
acceleration that can change the speed of an object (a bullet, a spacecraft,
you) from less than the speed of light to greater than the speed of light. So
it does not matter how powerful your rocket engine is or how long it operates,
you can never reach, much less exceed, the speed of light.
Another consequence is that there cannot be observers moving at,
or above, the vacuum speed of light. The invariance of the vacuum speed of
light means that if something moves at this speed, all observers measure its
speed as that value. So an observer moving at the speed of light would, in his
own frame of reference, measure his own speed simultaneously as zero and the
vacuum speed of light. This is clearly a contradiction, so we conclude that no
light speed observers exist. Similarly, when something is faster than light,
all observers agree that it is faster than light; so an observer moving faster
than light would simultaneously see himself as moving faster than light and
being at rest, again a contradiction.
What the theory does not say is that there cannot be elementary
particles (not observers!) moving faster than the speed of light. The only
catch is that these particles are always faster than the speed of light.
Just as you cannot exceed the speed of light, these particles cannot move
slower than the speed of light. But (insofar as relativity theory is
concerned) their existence is perfectly consistent with the theory.
There are reasons why we don’t believe
that tachyons can exist: for starters, we never observed any, but also, their
existence could be used to violate causality, by using a clever arrangement of
them to send signals to the past. But relativity theory, by itself, does not
forbid their existence.

2228 hours. If
relativity theory does not forbid the existence of tachyons, then it is
possible, by similar reason that angels may exist, that is angels that travel
faster than the speed of light. -- This is a hair-brained thought but I'm
dropping it in anyway.
