Rob thank you for asking about my thoughts about push gravity
.
You may regret it and I can imagine some members reading you post will be saying "Oh no dont get him started he will never stop..."
For some years I have held a belief that gravity works along the lines first put forward by Le Sage in 1745.
I suppose it is aether based in so far as those who subscibe to the notion imagine there is a flow of particles from every star (and other bodies no doubt) in the Universe ... maybe a particle contained within the electromagnetic spectrum... neutrinos could be the sort of thing I speculate upon
.. however the flow of all these particles in effect create a pressure in space in fact I like to think space is teaming with particles..a somewhat infinite flow...
A mate of Newton was into the idea of push gravity (I cant recall his name) and I am confident that Newton was exposed to the idea... rather than embrace such a mechanical approach when asked what was the force of gravity Newton replied that it was the force of God which I find interesting as his push gravity mate was hunted down by the Church and done in
..apparently for his unhealthy influence over children but of course I see a conspiracy by the church not to let the power of God be subject to any further errosion
...
In such an environment of particles everywhere (all travelling at C or near it ...and I believe some nuetrinos have been attributted as near C) I speculate that gravity manifests via a shielding effect
...so we are stuck on the surface of our wonderful planet because the flow from above is unimpeeded whereas the flow that comes from under our feet has travelled thru the planet.... and so we have an imbalance in this flow which causes the effect most mistakenly call attraction but it an imbalance in the flow ..or gravity
(The flow for most purposes we could call the aether lets not get into the problem with it carrying light whatever... I know about the MM experiment but say that the gravity B probe in a mechanical sence is also mapping the path of the aether...anyways dont worry about that for the moment... just consider the particles flying about neutrinos etc and ask what do we call such if not the aether the ancients speculated upon)
Or think of it this way..you mention the solar wind..think of all the solar wind from all over from everywhere all stars... and if you are in a strong wind and sheltered behind a shed the shed may seem attracted to you but it is being pushed by the wind...as you would be pushed to the shed if on the windward side...actually add sand they can be our mythical particles for the sake of better metaphore... now dont take too much literal I am trying to cram a fair bit into a small space
... if you are really interested have a look at the site Ron built (below) I have been babbling about push gravity for years and Ron and others have placed it in the 2%ers club site
...
Now as to space drag I suggested space would be sticky ages ago and that what the pioneer craft would run into sticky space when they burst thru the heliosphere and that they would slow (and in fact in time will appear to stop and then accelerate until they appear to be racing away from us at (whatever speed our solar system is orbiting the centeral ..lets call it a black hole to keep everyone happy
... I think its 350 klms per second but not sure without looking it up..orbital speed anyways..now it seems that the craft are slowing... NASA though otherwise and are somewaht at a loss to explain the observation and suggest leaking "stuff" slowing them whatever...but I say it is simple, the push of stella space working to grab them whilst the rest of the solar system continues..or the drag of all those particles... anyways at last peek they were slowing ..if it is leaking fuel or coolant they will stabalise at a new relatively constant speed...however if not a leak they will continue to slow... so time will tell if they can keep track of them...and if so we will have observational evidence that space does in effect drag which comes about from the aether or whatever we need to call it when the concept is resurected
... as it will have to be I feel
..what will we call all the HB's flying everywhere??? they can not be confined to existing only in stuff one would think but I expect we could expect them to be everywhere..another part of the flow you see
...
General Relativity is geometry and as such it can not control or influence space ... General Relativity revells in the fact it requires no force... well of course it requires no force because it is the observation and not the machinery of the Universe... General Relativity (as I understand it and I do not pretend to understand it very well which means I am presumptuious when even taliking about it) as I said is geometry and can only ever be how we record how mass and space relate... and mass and mass of course...
Curvature of space surely is a comment on the space time grid as mapped by General Relativity... The "cubes" of our 3d (er 4d) grid become smaller the closer to mass reflecting greater gravity and as such enables us to have a map of space and a way to place within it matter (with mass of course) ....so I simply say this.. General Relativity offers no force for gravity
, neither attraction
or push
gets a look in upon my understanding
.. the force comes from the math itself
... and as such Dr A in a masterful stroke took science forward and like Newton had the good sence not to bring up the aether or erode the force of God for certainly I can see no other force as responsible for gravity in the GR context...
What is space...
Space is everything ..we are in effect in space..those gaps in an atom are space... space is the flow of all particles able to do so in everydirection from every body and every time...think of it this way..hold up your finger and ask what particles reasonably would reach this point...well when you think it thru something from everywhere will pass that point and that is true for ever point in the Universe.. and when one thinks about it that way it is not a long strech to imagine that all these presumed particles must push and places of greater or lesser pressure will present to us as gravity.
Yes I have a TOE is back in general chat someplace and it is constructed upon the push approach to the Universe...
That you for asking
