I understand that Arp’s work has not been confirmed but then two patches to the standard model, dark matter and energy have not been confirmed yet either. The book is from 20 years ago and has been take seriously by Hoyle, Narlikar, Geoffrey and Margaret Burbidge and many other reputable...
So as far as I can see the kinetic energy a particle could be continuous but we have no way of measuring it. We know it is quantized when it is in a system where we give it quantized pushes.
So we don't know much and there is no experiment we can do to understand my original question (thanks...
Excuse me if I shift to cosmology. From what I understand the observed red shift of stars should come from three factors - according to the present model - First is a red shift given by the recession velocity (or general expansion of the Universe) second by the red shift caused by light having...
What if I use the lasers as clocks - measure the pulses, divide many times and put the data to a readout. Shouldn't the clock (laser) on the mountain be slower?
I do understand that light as it falls into a gravitational field it gains energy and moves to blue and the opposite happens as light...
Is this the question you want me to answer? Rather offensive actually. You imply that aside from being ignorant (which I admit) I am also stupid.
What I have been trying to ask is inertia a factor in the stability of clocks? It is in my pendulum clock, my balance wheel watch and in the...
This is just what I was trying to understand. The stability of the electronic clock is at least partially based on the fact that the mass is fixed.
I would like to say more but it is not a subject for this forum.
I realize there it isn't possible to pin down shape of the nucleus or where any bits are at anyone time but is there movement or rotation in the nucleus?
I have heard that "spin" is actually spin with angular momentum and other that say it is "intrinsic" (whatever that means) and doesn't...
OK as I said I’m not the expert.
But then you say:
Here it sounds as if you are not sure how it works and I never suggested it might be a sphere.
You say:
Well it should be or if it is not then something is wrong – IMHO- tell somebody who has just had his car smashed by inertial forces “well...
I got this from: http://hyperphysics.phy-astr.gsu.edu/hbase/Nuclear/nspin.html
“nuclei often act as if they are a single entity with intrinsic angular momentum I. Associated with each nuclear spin is a nuclear magnetic moment which produces magnetic interactions with its environment.”
As I...
I do understand English. Most people in this thread talked about how to synchronise clocks - very little on the physics.
Cut me out if you wish.
Tired of being bullied by the powers on this forum.
You qualify the above with (pendulum). Isn't it possible that if you drill down into the mechanism of all clocks you will find Inertial mass somewhere in the regulating mechanism.
Thanks, this is what interests me, the how or physics of the regulating mechanisms of clocks.
The various versions have muddied the waters. The one that needs explanation and inclusion is the real simple one – the one where I spin around, my hands are pulled out and the stars spin around me – or Mach 0.
As you point out there are dents in Mach’s principle (talking about Mach0 here) –...
I realize that you and the other leaders & moderators of this forum are not fans of Mach’s principle. This has been made clear to me by the moderators as some of my previous comments were deleted from another conversation.
I thank you very much for you explanations. I will try to get my head...
So we are back at Mach's principle.
Both of your platforms are rotating in relation to the stars. So not only is the kinetic energy of the clock tied to the stars but also its tick rate.
Or that is how I see it! IMHO as they say
The experiment done by Hafele & Keating took clocks around the world in two directions and compared the readout to a static clock to measure time dilation effects. Everything fitted nicely with Einstein’s predictions.
To avoid confusion let’s move the clocks way out in space to a real inertial...
I said: How do we decide what is a clock and how do clocks that rely on different technologies stay synchronized?
The how was the interesting part for me.
That was the discussion that I hoped for - the physics of clocks - how do clocks that rely of different principles stay synchronized? (or...
Not in the least. Most people who contributed to this little discussion talked about synchronizing clocks. I'm not interested in that at all.
This above is interesting to me - how clocks work - for example the balance wheel clock as perfected by Harrison shifts energy between the inertia of...
These quoted are all "good" clocks. It is fairly easy to see them synchronized. I didn't say that we didn't need another clock. It is obvious that a clock cannot exist by itself. The existence of one clock implies a second clock.
I just probably didn't word the question very well.
What I am really interested in is how clocks work. What is the process in one type of clock that makes it synchronize well with another type of clock? Is there a common factor in good clocks that allows the different technologies to offer a...

"Nuclear Spin
It is common practice to represent the total angular momentum of a nucleus by the symbol I and to call it "nuclear spin". For electrons in atoms we make a clear distinction between electron spin and electron...
No not a research paper. Trying to get my own thoughts in some sort of a shape.
So in my clock one of the stabilizers is the inertial weight of the pendulum.
Does the inertial weight of the bits of the cesium atom provide stability to the atomic clock?
I have a lovely pendulum clock on my wall. It is accurate to within a minute a week. The speed of the clock is regulated by the equivalence of inertial mass and gravitational mass. What about the other clocks? What do they depend on to be stable (lets assume we are not traveling at enormous...
From outside the black hole we can detect the change in mass after two black holes merge. Isn’t the detection of the change in gravity a type of gravity wave only slower. As I said above if I can detect the total mass beyond the event horizon why can’t I detect the masses settling down (as seen...
I can know the mass of a black hole from the outside and when two black holes merge, say 14 and 7 solar masses, and I can tell what the internal mass of the black hole is after the fact. I get a nice clear signal, the mass makes a big distortion of the local spacetime. Why can I “see” the mass...
It seems as if the ringdown happens after one black hole joins another and all the mass is beyond an event horizon. The ringdown could be noise as the masses settle down beyond the event horizon.
Information waves continue to exit the black hole as “ringdown” after a mass goes beyond the event horizon. This seems to be confirmed by the recent LIGO experiments. But also as I understand it time almost stops beyond the event horizon. So why do we still hear what is going on inside?
I read recently that no information comes out of a black hole. Doesn’t the mass information exit a Black hole with ease? Say I am orbiting a black hole and looking away. If while looking away the black hole gobbled up another star I could tell immediately that something had changed inside the...
The paper is about the origin of Inertia. I suppose, however, with the principle of equivalence you can interchange gravity and inertia at will.
And you are right he never came up with his promised complete theory.
In post N.4 Chronos sent a link to a paper by D. W. Sciama which agrees nicely with my non-academic (a polite way of saying it) world view.
From Sciama's paper:
“If the rest of the universe determines the inertial frames, it follows that inertia is not an intrinsic property of matter, but...
Peter,
Having read the rules (a bit late) I now realize that I shouldn't have posted at all. I find the Big Bang abhorrent from both a technical physical and from a philosophical point of view. Also I have no degrees.
I'll send you a personal note with a question or two. I hope you will...
Thanks Ken G, I agree that maybe we should work with Universe we find ourselves in. And thanks and to all who have contributed to this discussion.
[Moderator's note: personal speculation deleted.]
A different angle…. (Assume flat Spacetime)
I am mystified by Kinetic energy & Inertia. It is assumed that inertia has no limit and experimental evidence seems to bear this out. It is by far the most powerful force in nature. It would theoretically be possible to use any amount of energy to...
Spacejunkie,
I found this definition of Mach's Principle very difficult to follow. Nowhere near as clear in writing as the paper linked by Chronos (http://articles.adsabs.harvard.edu/...=2&data_type=GIF&type=SCREEN_VIEW&classic=YES) by Sciama.
Thanks all the same
Peter
Thanks I understand most of your criticism and the reason why the gyroscope might not be perfectly stable. This comes from the twists and the dents in the underlying space – or spacetime if you prefer.
Let’s just say that the preponderance of inertial forces come from distant matter...
