Sure it is known that a large amount of mass situated in a small-ish area, such as a planet or star cause a gravitational well. This well is the bend
or bump in space-time. The potential has a fall off effect however just as anything else does. Now the only object in our solar system that requires
2nd order corrections for this space-time curve effect is mercury. This correction is quite a small one and is used to explain the fact that in
newtonian motion you expect all planets to orbit in circles around the centre of mass (ie the sun), and in keplarian (sp?) motion everything can orbit
stably in ellipses where you get a near and a far point with 2 focal points. Classically however this motion is fixed in place and any precession is
determined by drag... (so like dust or general stuff that the planet sweeps through each year) so it is a very small effect!
Mercury on the otherhand is close enough to the sun that there is a space time curve effect which adds significantly.
Now, my point is that on the sales you are thinking of there is little to no dialation in any useful way between a object say in orbit or a space
craft leaving our solar system. The pertubation or gravitational attraction to the sun at those distances for a small object is extremely small.
It is like the example of astrology (where I have read people saying) "Well its from gravitational effects, like when a baby is born, it feels the
gravitational effect from jupiter"
when the truth is, the gravitational attraction from the mother and the midwife is higher than any that Jupiter has.
If the fall off of this effect is 1/r^2 which is a good bet... you will find any effect to be absolutely tiny for the sizes of objects we are talking
about being 'man made'
Voyager leaving our solar system boundary has been very interesting in itself... its left about 20 times now haha which is a really good indication of
how fuzzy that boundary is. Pretty awesome mission
