!!! Black Hole Gravity - speed of gravity

Hi Painius The heart of my "Spin is in theory" is the electrons spin at
'c' and emits photons at the speed of its spin. This is reality from the
beginning of spacetime,and our present space time. The spin speed of
the electron is a constant. The speed of the photon has to be a
constant. Bert

I would have to agree with you on this, John. As sort of a
footnote, since you have evidently read the book in question,
maybe you could help me out on something?...

On June 9, 1952, less than three years before he died at the
age of 76, Einstein wrote in his note to the 15th edition,
"Physical objects are not _in space_, but these objects are
_spatially extended_. In this way the concept 'empty space'
loses its meaning."

How do you interpret his words in terms of whether he thought
space itself was "nothing" or made of "something"?

His "Note to the Fifteenth Edition" is essentially an introduction of
"Appendix Five." Rather than trying to glean deep significance from a
one-liner from the note, I would suggest that you read (the 24 pages of)
"Appendix Five" (and ask questions about that if you wish).

I interpret his words to mean exactly what he explains them to mean in
"Appendix Five."

That's my whole point. I don't understand App. 5. Okay,
your response above was not a very trusting answer, and i
understand why. I'm being sincere, here, John.

Einstein's intro and the appendix itself would seem to
indicate that he was never actually opposed to there being
some kind of fabric to space. He was unhappy with the
old, static aether, to be sure. And yet, to me, Einstein
was not ruling out that space may still have some sort of
structure to it. He never became specific as to the nature
of this structure, but he seems to indicate that space is by
no means empty, or void.

So i was wondering if you understood the text better than
i do and could tell me if i'm wrong, or maybe i'm close to
comprehending what Einstein was writing about?

What do you mean by "electrons spin at 'c'.."? Do you mean that their
surface is moving at c?

Adam No surface. The electron structure is a cloud. The cloud is
composed of photons,and virtual photons,and it is this "c' spinning
cloud that emits,or absorbs photons.*natures balancing act". Adam
they have just detected the electron spin. If it is spinning at "c" like
my theory predicts I should get the Nobel Prize Bert

I still dont understand what you mean when you say the electron (or the
electron cloud) spins at the rate c. Are you saying the cloud has a
surface, and the surface has an equator that spins at c?

Also, i wonder how much c would change for a given
change of pressure? We know that the force of gravity
changes as the square of the distance, so presumably
the change of pressure would be proportional, but it is
possible that even a huge change of pressure would only
slightly affect the value of c. Can this be predicted, and
if true, do we have sensitive enough instruments to detect
a small change in c in the areas of space frequented by
us (still near very large, high-gravity objects)?


By definition c is the speed of light _in vacuo_; if you're measuring
the speed of light through any substance you're not directly
measuring c. As for the effect of pressure, a gas's index of
refraction, which is related to the speed of light through it, is
proportional to its pressure.
