Preamble:
I ain't no physics expert!

I'm under the impression that there are no answers to gravity (i.e. a
graviton is a hypothetical particle) If I use a gyroscope  and place
it at an angle off a table end it doesn't fall down. There is an
existing explanation for this phenomenon involving perpedicular force.

*I don't like this explanation because in tests my gyroscope never
tries to slide across the table it is leaning on - friction doesn't
seem like it would be strong enough to counteract any lateral forces*

My question is this: 

Is there any reason why the following alternative explanation can't be true. 

If Gravity were a particle like an Electron, that a gyroscope creates
a gravity current, and that the current is completed where the
gyroscope touches the table. I.e. the gravitons travel to the point of
least gravity resistence down the gyroscope to the table where they
then travels straight down to the core of the earth.

Hope my question can be deduced from the above :)

I can recommend cosmology books by Steven Weinberg, who shared a Nobel
Prize for proving that electromagnetism and the weak force--two of the
four basic forces (the others are the strong nuclear force and
gravity)--came from the same source. Try his book, _Dreams of a Final
Theory_.

Almost any cosmology book will include gravity information and
theories. It's a hot subject, and you'll find plenty to read.

Do a web search for "grand unified theory" and "theory of everything."
Also search for "gravity waves." You'll find lots of info on gravity
with these searches.

I have many friends who are physicists--some are experimental
physicists and some are theoretical. I love reading about cosmology
and subatomic physics, then picking their brains.  :-)

The rate of change of the angular momentum of any object (including a
gyroscope) is equal to the net torque on the object.  Gyroscopes are
subject to the same simple laws of Newtonian physics as every other
classical object, and no complicated new explanations are necessary. 
The only difference between a gyroscope and other objects is that for
a gyroscope, the simple Newtonian laws say a different thing from what
most people's intuition says.

Thanks for the comments <u>Dance the Con</u> and <u>Race Car</u>. I'll
look into it furthur.

I wonder if HTML will work in here
