but if there are these neutrinos, wouldnt by theory (since the are a massive particle) they have to propagate some sort of gravitational properties? (and as i understand it we dont really know what gravity is either, rather we just have models to demonstrate the effects of it)

www.thefinaltheory.com... - new book on which this discussion may be already solved


Sure, but neutrinos may have only kinetic mass, just like photons. Photons don't cause gravity, but they have mass, otherwise they would have no energy (because E=MC^2, and if M = 0, then E = 0).

I am kick-starting this tread since new papers have been published about the Pioneer anomaly since this thread began.

First, there is a new paper out on, September 30, 2005. The ESA Advanced Concepts Team, proposes methods for testing current theories on the Pioneer anomaly. Options for a non-dedicated test of the Pioneer anomaly PDF


And a September 17th, 2005 International Journal of Modern Physics by R..Foot. Mirror matter-dark matter PDF


The latter article also relates to R. Foot's and R. R. Volkas previous article in 2001 from the University of Melbourne, Australia.A Mirror World Explanation for the Pioneer spacecraft anomalies PDF


I'm no expert, so what do you think? Could the anomaly be caused by, and is there such a thing as left handed, or mirror matter?

Don't be prematur. Just because unexpected drag has occured doesn't mean the theory of gravity is wrong,.


The thing that is strange it Pioneer is not slowing down as drag would cause it too its infact speeding up. The acceleration is tiny, less than a nanometre per second per second but nobody knows why its doings this.

They have already ruled some stuff out like software errors, the solar wind or a fuel leak.

If the cause is some gravitational effect, it is not one we know anything about right now.

Could it possibly be caused by another planet, like the hypothetical "Planet X"?

Perhaps there is a body with enough gravitational pull that is causing the anomoly...

Just my $0.02.

This could be this source of the Pioneer anomolies.

www.pparc.ac.uk...

Basically this theory proposes that our understanding of Gravity is flawed and that it acts differently at different distances. Quite a fasinating theory actually.



Milgrom's theory has been worked on by a number of astronomers since and Dr Zhao and Dr Famaey have proposed a new formulation of his work that overcomes many of the problems previous versions have faced.

They have created a formula that allows gravity to change continuously over various distance scales and, most importantly, fits the data for observations of galaxies. To fit galaxy data equally well in the rival Dark Matter paradigm would be as challenging as balancing a ball on a needle, which motivated the two astronomers to look at an alternative gravity idea.


Allthough it still doesn't touch on what Gravity actually is.

Nice research

This could very well be the explanation we're looking for.

NO....It was slowing down.
