[geocentrism] Re: Can we really say for certain?

Philip,
 
Do you know how a "gravity slingshot" is supposed to work? The alleged "probe" 
does not "bounce off" a "bouncy" medium. The thing is supposed to be captured 
by the planet's (or moon's) "gravitational field", be pulled around behind the 
planet, and swung off on its journey. This is like strip the willow, not Donald 
Bradman knocking a cricket ball to the boundary. This is why I said that the 
acceleration it received on approach would be completely negated by the 
deceleration it experienced on recession. This is a "field," not a bat and ball 
game.
 
Besides all this, the accuracy required for this science fiction manoeuver, 
over billions of kilometres, is absurd. I will not produce detailed mathematics 
on the forum, because many would not follow it. I appeal to your common sense 
and everyday experience instead.
 
As regards, "Can you discuss the physics, without being sidetracked by the 
accentrists flawed assumptions?", no I cannot. The vast distances between 
planets in the acentric model is fundamental to the whole issue.
 
The alleged probe would be pulled back, with a force that is basically the same 
strength and the opposite direction to that which it would have received on 
approach. Gravity slingshots are nonsense.

Ok ... so ignoring Jupiter and just coming closer to easily discernable

as I described. Can you discuss the physics, without being sidetracked by the

assumptions. 

Since I last posted I discovered some more detailed information which also 
makes more sense and adds energy to my projectile. 

As usual I convert the math to practical realities, so that all can see my 
point. When a cricket ball is hit by the force of the bat swung with great 
force, some of the batsmans energy is added to the ball. The back swing sends 
it for six behind the wicket. Do the vectors. 

If I threw a "perfect bouncy ball" at the moon as it was coming towards me over 
the horison at thousands of miles per hour, (GC speed) It would hit the ball 
like a cricketers bat, and bounce it off even further into space, adding part 
of its own kinetic energy . 
Do the vectors. 

I followed the vectors. The equations made no sense to me. But you can verify 
them for me if you will Neville. At the following sites.

gravity like a magnetic field would I think make for an almost perfect bouncy 
medium for transferring energy or work.Therefore as in practise we cannot 
bounce our projectile off the surface, we can bounce it off by absorbtion in 
the gravitational field.

A poor analogy of what I mean. 
A diagram should not be needed, but consider a cricket ball that is a 
theoretical North magnetic Pole being thrown at velocity in the direction of 
rotation close to a rotating South magnetic field. Ok so its Don Bradman 
swinging his bat which has a south polarity at its extremity. Its a close miss 
pass the end. No collission damage. But no doubt the ball will get an injection 
of momentum... (Basic electric motor?) 

regards,
Philip.
