Nothing That Matters

Lets go back to my post about "Voyager Shortchange", in the light of my post below, on Dr Lisa Randall's theory of negatively warped 5-dimensional space around us. The two have much in common. We had seen that Voyager Spacecraft is approx. 8,000 miles too close to us, than it should have been according to calculation as per latest theories of gravitation. Among the various hunches, one was about modification of Newtonian inverse square law of gravitation.
Now Dr Randall postulates that we are surrounded by a five dimensional space, which would have given us an inverse cube law of gravitation, but for the propounded negative warping of this dimension, so that we perceive it as only 10^-31cm wide. (De ja vu - I Have been proposing that space also comes in quanta - you can't have space less than a minimum size - which I had rough guessed as 10^-31cm.)
If we were in a full fledged 5-dimensional space, law of gravitation would have been inverse cube law. But because of warping of the 5th dimension, the gravitation inverse square law would have very close fit, over short distances. But over astronomical distances, the miniscule effect of curled up 5th dimension would make gravity a wee bit weaker than inverse square law.
We may recall that Voyager craft derived its speed from gravitational sling-shot trajectory around large outer planets like Jupiter and Saturn. Therefore this slight weakness of gravity would explain the voyager shortchange over large planetary distances.
This is easily verifiable by precise measurement of gravity, in laboratory or of astronomical bodies.
Voila! that will also be a verification of RS-1 and Rs-2 theories.
