Alex,

Here is the experiment performed over 200 years ago.
It is based on the torsion balance.

Lets start another thread for elaborating further on this, mate...
This is too basic for this place, where GR discussion is taking place

Steven,
Alex is talking about definition.. or even the very existence of attraction force...
In a discussion with me couple of years ago, he was arguing that the attraction can't exist because, according to him, there is no mechanical way to communicate this force to other bodies ("come to me... ").. while it is quite easy to understand "pushing" force (as result of collision).
So, he was arguing (and he still does, obviously) that the attraction force between two bodies is actually a manifestation of push, resulting from flow of hypothetical particles (we called it "push_itron" or "pussitron") coming from everywhere, and effect of mutual screening of that flow by two nearby bodies.. So the attraction, according to him is just an illusion.
Obviously, this discussion is not over yet

EDIT:
"push_itron" is spelled as this to circumvent the built-in dirty language detector of this forum (at least it was working last time when we had this discussion)

Sorry I only got back a few minutes ago.
Thanks Steven I will look at the link.
Thanks Bojan for for a brief history of my time..on push.
I have to do more stuff now so I will be a while reading everything here.

There is a limit to what one human mind can comprehend.

Does anyone here think that the human mind can comprehend itself? Let alone the Universe!

Bert
Bert I presume you mean other humans as I am sure you know by now I will happily answer yes to your questions

Subjectively each of us are here for an eternity as we can not comprehend a world in which we do not exist and from there we realize we are indeed the center of the universe (observable universe us being the observer) and gaining the realization we are so important how could one be wrong about anything let alone everything.

I am just happy I have found all the answers before I pass on. unfortunately I can not remember all the questions.

The experiment also disproves push gravity. If you replace the larger spheres with a different mass but of the same diameter, the result should be same, as the screening of the "push_itrons" is a function of diameter of the spheres not their mass.

This clearly is not the case.

I enjoyed all of that Steven.
Bojan explained my point very well.
..although I am not fixated upon a specific particle but simply that what we observe as attraction at work is not along the lines of..to make it simple...a message of "come here"...anyways Bojan covered it well enough.

I can not see why the prospect is difficult to speculate upon ...how else can a field work other than by a pressure of particles...I submit the Pioneer slowed because once outside the heliosphere as they would encounter a stronger gravity field rather than a weaker one... mind you I have zip support on this even though they did what I predicted..and I made that prediction on this site using a rather elaborate metaphor... but it could be like Bert's dog thing..seize a fact and fit it to your pet idea...anyways I am not the only human who can be accused of such folly... still I was right and NASA were wrong ... but I recognize it has a Jack Russel taste to it.... anyways I did not want to get onto this...I am sorry ..I swore all this was behind me.

I have never said screening was related to area or volume etc. Clearly mass is key our observation make that obvious.
AND nothing I propose need alter any sums we currently use... and lets face it Steven although we have many formula gravity related we still have absolutely no idea of the mechanism... I know you find it curious one needs a mechanism but without a mechanism..a particle..a machinery we have little more than sums that are useful and work but tell us nothing about the process..I submit that what we have borders on belief in magic...space bends because of mass etc but why what is physically going on..if we dont know what is physically going on we know nothing..Gravity is a field so it must have particles in there somewhere if we recognize their significance and fit them in maybe all the forces can be united...but to grasp at GR calling it a field and not looking at why we will always be in the dark...

A push field offers acceptable explanations for the problems dark matter seeks to cure...and what that means really is while you have attraction as a concept you have to add mythical material..dark matter.

Sorry to rant I have had a stressful day and should not use here to relax and speak my mind.

So let me get this right.

(1) We don't know what a push particle is.
(2) We don't know what propels it.
(3) We don't know the origin of a push particle.
(4) We don't understand the push mechanism as collisions can neither be elastic nor inelastic.
(5) We can't classify it in Particle Physics.
(6) We can't isolate it in the laboratory.

But it's not a mythical material like "Dark Matter"

I'm glad you have clarified it Alex.

Regards

Steven

Aha!!!
I have only one theory.
It is kinda of a secret
My theory is that the human race will be gone before they can even get to another planet to save themself
(unless they get past the theory about the speed of light ).

When you put it that way Steven it sounds as if you see no hope for the idea which surprises me

Still let me deal with the matters you raise.

1. That is correct.... but does that really matter in a speculation such that I indulge in... lets face fact we are not sure we can find the HB but certainly the HB could be a PP after all the HB is the particle that scribes the Higgs field..and what is the Higgs field..it is a field made up of Higgs bosens..how is one to see this field working I ask...are HBs sitting around not moving waiting their opportunity to give a particle mass..do sit in the voids ? are they maybe our dark matter?. how do they give a particle mass?...could it be that HB's fly around at near C to create the Higgs field which I submit would be the sort of thing I suggest. If we cant find them how do we know what they do or where they are..they are as illusive as PPs

If a push particle exists in its own right it may simply be something we already "know" about...even a neutrino sounds like a good candidate..and lets face it Steven Neutrinos and others have been suggested for dark matter ..I suggest that such an approach is not that different to mine...They dont know..I dont know but neither they or me need give up on the premise because we dont have the detail nailed down..if that were the case all speculation upon dark matter should be disregarded..

2. Do we know what propels dark matter? we dont know what it is or if it is there it exists because we are determined that attraction rules the sums... however if dark matter is say the neutrino it is clear what propels it.. i think it is clear.
I think PP will be somehow connected with the EMS ...but clearly anything on push is speculation...and I think most ideas start as speculation and someone asking..what if... now plenty of crap comes from such an approach but also plenty of valid discoveries come from someone speculating upon possibilities based on their observations and thinking...

I never suggest I have the answers but in this area given the little we know I do not see a problem. I know GR is complex etc but it tells us very little really and clearly fails us in some areas...we now have someone fixing it or fine tuning it..no problem but even so we still have not credible mechanism.
The graviton is a mere speculation I believe ..it has no lab experiment proving it does it? Even the HB is an educated guess at this point... I dont think any thing is rock solid when it comes to our understanding of matter.

3. We dont but if it is a neutrino we do...if it is a HB we can work it out..

4. I saw something on the HB showing the HB running into a quark and I thought thats cool a PP would be the same maybe.
Again I speculate for I dont know but if for a moment the push idea was given any credit and other minds offered input as to why it could work rather than why it can not work more would be built...lets face it everything is built from an idea...GR BB etc is not different. AN idea is born an infant not fully developed and complete.

5. I dont know that anyone has or will try.
I imagine whatever would fit the bill will be very small and travel at near c and such an animal would not be easy to observe...and thats the case for neutrinos and HB..How long have they been monitoring their underground tanks of window cleaner or whatever they use...One such attempt I noted the other day..been years at it and only had one "flash"...
My point is simply no matter what one seizes up[on finding one is not easy at this level of smallness.

6.Look I did find one but being so small I lost it
Steven if we have so much difficulty in finding stuff we are reasonably sure is there (HB neutrinos ..er I think many particles are inferred by their decay trails) think of how much trouble we will have finding anything... it is no good to say ..find one..as if everything found to date was easy work.

Thank you for taking the time to provide regions to think about.
I appreciate you taking the time but think about what I have said... we can not unite the forces and have had a long time now and we are not going anyplace..is it such a bad thing to specualte upon a mechanism...I know we dont admit the aether but I suggest things would work better with that type of fram work.MM proved it was not there etc but I suggest that if we can not find the HB or the neutrino with a greater ammount of effort that we may have been too hasty to draw the conclusions that nothing meant nothing..there is always something and it is this something that we do not yet understand.

I appreciate your abilities and that math is central and you maintain a discipline to avoid speculation ..that is good..however rather than try to point out why such a concept could not work please indulge a speculation as to the many difficulties that universe such as I suggest would overcome...and finally it is only the concept of attraction that is causing problems..

It is clear galaxies are not held together by attraction but some external force (which must be a push one must conclude)...so we have a force strong enough to hold galaxies together but this massive force does little else..why would gravity work as a push at that level and not down here.


ANYWAYS I am one man how can I present a complete theory of everything no one has a model yet even S Hawking ..and Dr A tryed all his life...and many great men have not come up with all the answers so although I do my best I cant do everything.

DAm it you have got me going again ...I dont want to think about this stuff anymore...

AND may I round off with this....why did the pioneers slow using all we think we know...was it a jack russel event or could a mug like me have just got it a little right?

I know you cant come straight out and agree Bojan

No I was happy that you could state my position without comment identifying what your thoughts were... I have always felt that you never quiet agreed with my general premise ... I have some math weapons these days but I wont bring that in until I have an experiment or something...I am still only developing the premise of the general idea.

A better example without the irony may be feeling hungry - hunger is real, folks but when I'm hungry I'm the only one who knows it;

3) Reality by Concensus - what politicians practise - eg: "Giant Jack Russels exist because me, my mate and everyone else agrees that they do - so they are real".

But Gravity (or the 'force of attraction) falls well and truly into (1) above. ?? Illusion ?? - Only if one's mind is in either of the other two realities !!

PS: A topic for a separate post, methinks !!
Sorry for being late to reply Craig.

I agree with your comments but again note that the area of particle physics is not one where one buys some scales and tape and runs out and write down all the answers.

I made the comment that finding a neutrino was not easy..check this but one example of the difficulty in measuring ..er even finding something the standard model includes in the game...

http://www.sciencedaily.com/releases...0109002326.htm

Now that is one of many stories on the difficulties dealing with finding and measuring a neutrino...one candidate for dark matter. And what about the HB I dont think it at this point fits reality one ... and notwithstanding all the good reasons why it is there the reality (1) is that it is not yet a reality.

So why be so harsh on a mug like me with no budget I cant produce a PP or take the premise past speculation. but the reality as always comes down to available funding...so I conclude cash is the only reality worth considering..... but give me $250,000,000 and I will search for the rest of my days for whatever you like....

Apologies if I seemed that I was being harsh. I actually thought my post, which you quote, contained some pretty cool distinctions, (even if it was prompted by my frustration about disrupting what could've been a really interesting discussion on GR). I don't think I'd ever elucidated those thoughts in writing before. (Not bad for a hamster, huh - Witten's Hamster, that is).

With the benefit of further posts on your topic, I now 'get' where you're coming from. But to me, it seems like a difference in semantics. (As Steven pointed out). Your questions it seems, & as I think you have pointed out, will seemingly all come out in the wash anyway, courtesy of experiments & research, presently being funded as a result of Lamba-CDM thinking.

I'm still left puzzled by why graphene electrons speed up as it cools down, though ... fascinating !!

Cheers
