Quick question, if the properties or electromagnetic and gravitational are basically the same is it possible to block gravity like you can block em fields using a Faraday Cage or am i basing this on bad science?

There is gravitomagnetism, very likely to be proven, see http://www.esa.int/SPECIALS/GSP/SEM0L6OVGJE_0.html.

Sorry, what i meant was there are a few similarities between them and if this could be one. I have read about gravtomagnetism in the new scientist about a year ago...i must dig it up out of the pile of them under my bed. Thanks

Zapp, i think that an incomplete (and not always accurate) concept of GEM can sort of be had with the comparative inverse-square field behavior (what makes Gauss's Law work for both EM and gravity) and the additional postulate that pertubations in the gravitational field propagate at the same speed c as do perturbations of an EM field. a set of Maxwell-like equations for either case can be constructed that are consistent with the inverse-square and finite speed properties each case has. it's not an adequate description for real physicists, but for those of us that don't do GR, it's a sorta-kinda understanding.

At the moment i am studying a level physics and so i do not understand all what these contributers are talking about, but i am eager to learn and i will now read up on it. What I was originally talking about was the original Newtonian view of gravity ie. the inverse square law etc. Thanks
Quite; I don't really understand how the classical magnetic field is supposed to come about, but I've been told that it's to do with a relativistic transform of the 'electric' field - so they're actually one and the same. Presumably if viewing an electrostatic field relativistically yields a new field, viewing a gravitational field will do the same. This had never occurred to me but is fascinating.
