Dear Friends,
Here's the latest from Dr. Tom Van Flandern.

Does Gravity Have Inertia?
Inertia: the tendency of a body at rest to remain at rest and the tendency of a
body in motion to remain in motion.

Abstract. ÃÂÃÂÃÂÃÂÃÂÃÂà ÂÃÂÃÂÃÂÃÂÃÂà ÂÃÂÃÂû Gravity makes heavy and light bodies fall at the same rate. Gravity
obeys the ?equivalence principle?, and is just "curved space-time geometry" in
geometric general relativity. But space-time curvature alone cannot initiate
motion, and changes in momentum still require a force acting. Moreover, gravity
can deviate slightly from the ?equivalence principle?, and ?space-time? is
really just proper time and does not involve any curvature of space. The Le Sage
?pushing gravity? concept is a better way to explain the physics of gravity. For
forces other than gravity, the momentum transferred must be shared by all
particles in the target body, producing what we call ?inertia? -- a simple
dilution of momentum. Gravity obeys the ?transparency principle?, allowing
momentum to be transferred directly to each particle. Without need for dilution
of momentum, gravity has no inertia. ÃÂÃÂÃÂÃÂÃÂÃÂà ÂÃÂÃÂÃÂÃÂÃÂà ÂÃÂÃÂë
Gravity is different from the other known forces of nature. All
bodies, big and small, accelerate at equal rates in any given gravitational
field. That property is opposite to our everyday experience, in which more
massive bodies require more work to move or accelerate than less massive ones.
That gravity accelerates masses of all size with equal ease is so anti-intuitive
that people universally believed otherwise until Galileo?s demonstration at the
Leaning Tower of Pisa. He simultaneously dropped a heavy and a light mass (both
heavy enough that air resistance was not a factor), and observers below tried to
time which hit first and by how much. But to the astonishment of the observers,
who were certain that the heavier body would fall faster, the two masses reached
the ground at the same time.
