and you're are getting close to the crux of the fallacy.
Relative to the entire universe, of course.


The spacecraft is part of the universe. All the rest of the matter in the universe excluding the spacecraft is also part of the universe.

You have (I trust) no problem with the concept of a spacecraft accelerating, provided that a force is applied to it?

Now, the mass of a spacecraft is m = U*(mf_s), where U is the mass of the universe and mf_s is the fractional mass represented by the spacecraft, right?

Why should there be a problem with an aggregate mass of U*(1-mf_s) accelerating under an applied force? The principle is exactly the same; it's just that the quantity involved is larger, and closer to the total mass of the universe. Provided U itself doesn't accelerate (yes, I know I'm not using rigorous notation), nothing unthinkable happens.

There's no fallacy involved. It's just a question of scale.

It appears J.Woodward is working on a new paper that's estimated to be released in a few weeks.

Hey now, don't get your panties in too much of a bunch.
But your tirade is infantile and I don't want to get into it. I don't come here to be abused, if the quote is not removed and yourself reprimanded Talk-Polywell will be a lesser place for it. Please remove this insidious quote that you have put my moniker on.

If you are heartily offended by a light-hearted "Kool-Aid" reference well I think the mirror is a good place to begin for you, sir. Afterall you yourself admit at this point, the "Mach Effect" is more of belief system than a real physical phenomen.

93143::

Okay, so the rest (not the spacecraft) of the mass of the universe moves (ever so slightly) with respect to the mass of the entire universe and the center of mass of the whole system is stationary?

And you don't see any problem with the logic here?
You have (I trust) no problem with the concept of a spacecraft accelerating, provided that a force is applied to it?
Another facetious, rhetorical question ... give it up, you were busted.

darn right it is a question of scale. Now you have involved the whole of the rest of the mass of the universe, (but not the entire universe I should remember which universe I'm talking about here it seems). So now tell me how quickly is this information that rest of the mass of the universe has moved is transmitted to the center of mass telling it to stay where it is? (and at the same time perhaps you'll explain how fast the information travelled from the spacecraft to the rest of the universe telling it that it should move)

Hint: the answer can not be instantaneously as per GR.

Nope. I'm starting to wonder if you've ever actually worked a simple vector mechanics problem...

The entire universe includes the spacecraft. That's the key.

Busted how?

I was trying to lead into the rest of the explanation. Yes, I'm getting impatient and it's affecting my style. You seem to be too busy being contemptuous to actually understand what I'm talking about.

How about you come out and explain what it is you think is wrong with the conservation-of-momentum argument, instead of hinting around that I'm some kind of idiot for not figuring it out myself?

That's a completely different issue and you know it. Talk to Paul March about gravinertial fields and reversed-time waves; I'm not going to get into that.

Also,
how quickly is this information that rest of the mass of the universe has moved is transmitted to the center of mass telling it to stay where it is
is nonsense; either it was posted too quickly or you are somehow under the impression that the "center of mass" is somehow a separate, discrete thing rather than just the abstract concept of a mass-average of the "rest of the mass" and the spacecraft...

Bear in mind that according to current theory the universe doesn't have a centre of mass in the location-in-3D-space sense, only in the velocity/momentum sense...

Offended if you consider it not knowing whether to laugh or scratch my head. My tirade? Abused? Light hearted? Seriously? Cause that's not how you came through (e.g. the name distortion thing is in my mind almost a guarantee that I'm dealing with a teenager). You could've cleared this up earlier; it's curious you wouldn't have. And it's clear what I said, it's there in black on white.
Did you or did you not throw a fit only because the ME conjecture I had to mention to answer two people's questions is junk in your opinion, and because I refused to take responsibility for how credible or not said ME conjecture is, and had the spine to call your insistence that I am for the strawman it is? A rhetorical question.

I'm going to delete my off topic posts so this thread is back on track.
Afterall you yourself admit at this point, the "Mach Effect" is more of belief system than a real physical phenomen.
No, and this is why I can't take you seriously - and the only thing I'll reply to henceforth:
1- It's clear as daylight that I haven't and am not admitting any such thing either way. I'm only passing on the information requested.
2- I don't see how you can believe that it is or isn't a real physical phenomenon without proper research. Which is what J.Woodward & co are trying to see through. Or alternatively by debating the technicalities like 93143 is doing above and like P.March would probably be glad to do with you if you did more than call what he proposes junk.

If inertial mass is electromagnetic in origin you can manipulate it with electromagnetic fields. Feynman did not go into the implications of what he posited for engineering i.e. inertial drive.

I don't see why conjectures by some of the great minds of physics upset you so.

====

The question of course is why inertial mass = gravitational mass. If gravitational mass is geometric (per Einstein) and inertial mass is at least in part electromagnetic (per conjectures arising out of Maxwell and hypothesized by Mach and Feynman among others) there is a unification theory missing. Feynman called it one of the very big holes in physics. And yet exploration of this fundamental question is done out of pocket by folks interested in it.

Good on the people (March et. al.) doing this for trying to get answers from macro systems. So far all we have to go on is indications from micro systems (particles with similar behaviors but different masses depending on charge).

icarus,

I don't understand your hostility to exploring a fundamental question. Are you heavily invested in mass ejection rockets?

What would I suggest? Read Chapter 28 Volume II of Lectures to get up to speed.

And the title of the Chapter? Electromagnetic Mass.

Would that be by advanced or retarded electromagnetic waves?

As I said upthread: your knowledge seems to be stuck in grade school understanding of physics - or to be more charitable engineering physics.

Why not educate yourself some (always fun and sometimes profitable) and then come back and poke holes when you at least understand the questions. It is only one chapter in Feynman. How hard can it be?

I think Higgs is the fashionable answer. LHC may tell us for sure pretty soon. (It sure is an exciting couple years ahead, isn't it?)

Which reminds me: will anything coming of out LHC impact Mach effect theory? If so, what if any predictions does MET make for LHC results (looking in Paul's direction)? I know it has implications for Heim and (obviously) string theory and Standard Model.

No kidding. And I suspect there are yet more implications to nonlocality that will become apparent over the next century.

93143: As always, thanks for your contributions to this thread, they greatly increase my understanding of things I haven't studied enough.
n*kBolt*Te = B**2/(2*mu0) and B^.25 loss scaling? Or not so much? Hopefully we'll know soon...

Mach effect vs Mach principle vs Mach conjecture...

Post by Nik »

Is this related to the 'enclosed thruster' proposed a year or two back ? Where the energy density in a *closed*, tapered waveguide theoretically causes thrust ? I remember the uproar, and reading that the math comes down to a Y/N result depending on arcane, ambiguous interpretations of the physics. IIRC, the only way to conclusively disprove it is to build and fly it...

Uh, back on topic, given entangled particles may be half the known universe apart when they next interact, Mach's principle may have a mechanism...

Entangled gravitons, any-one ??

OT: Why doesn't 'Mach Effect' wiki have a disambiguation link to lengthy wiki on 'Mach's Principle' ??

( Apologies for spelling: One of our cats is helping me type ;-)

"Which reminds me: will anything coming of out LHC impact Mach effect theory? If so, what if any predictions does MET make for LHC results (looking in Paul's direction)? I know it has implications for Heim and (obviously) string theory and Standard Model."

As far as Woodward is concerned, the existence of the Higgs particle has no bearing on the M-E or what causes inertial mass in a GRT based universe. The interactions of the cosmological gravinertial field with the local electromagnetic fields in electrically charged elementary particles like electrons and quarks is the causative agent for inertial mass per Woodward and the Arnowitt, Deser, and Misner (ADM) model of elementary particles pended around 1960. In that model with Woodward's modifications to same, (See Woodward’s “Making History Safe for Historians” (MUSH) & "Twists of Fate:..."), the very large but finite negative "Bare" electromagnetic mass of these elementary charged particles is mostly cancelled or balanced out by their interactions with the gravinertial field. The small imbalance between these two competing agents results in the measured inertial mass of all subatomic particles. In other words as far as Woodward is concerned, the Higgs field and particle is just another error of the current elementary particle "Standard Model".

From Woodward's latest still unpublished paper:

"They (ADM) asked what the solution of the field equations of general relativity was for the case of a spherical cloud of electrically charged “dust”, which they assumed to have some bare mass. It turns out that this problem has an exact solution. And, as Abay Ashtekar pointed out in a review article on quantum gravity he wrote in 1990, the ADM model suggests that in a correct theory, renormalization should be unnecessary for gravity and electromagnetism compensate in such a way as to keep things finite in even the most extreme circumstances."

no. I think you are talking about the EM-Drive, by Roger Shawyer, not ME-Thruster. The name is similar, but they are worlds apart, completely unrelated effects, theories, physics and PLAUSABILITY.

Can anyone tell me if Mach's Principle and Heim Theory are compatible or not?
