List Members,
Recently Frode sent around a quote from Pari Spolter on gravity vis-a-vis
the true configuration of the Earth. I am going to re-quote, and include the
part before, too.
She makes two good points:
One is that you can't determine the density distribution from seismic data
alone. On order to justify the idea that gravity is related to the density
of mass, physicists have to assign a lot of density to the Earth's interior;
almost ever increasing density- the kind which wouldn't permit a hollow
shell to stand, nor cavern worlds to exist ( sound familiar? ) But the
interpretation of seismic data, which is unproven theory, depends largely on
the Cavendish experiments, which assign density to the Earth. But the
Cavendish experiments are also flawed- the gravity which they indicate for
large spherical balls can't be applied to large orbs. If they don't know how
gravity is caused, they can't determine how it will acti within a globe,
what to speak of a hollow one. They have no empirical perception nor
experimental proof. It is all unproven theory which rests on yet more
unproven theory. Circular reasoning.
Then she says: " This currently accepted Earth Model is inconsistent with
the law of sedimentation in a centrifuge." In other words, if the Earth was
formed by a centrifugal process, the denser part would have been thrown to
the OUTSIDE, not that it gets denser the furthe inside that you go.
From studies of seismic wave travel time, geophysicists have outlined a
layered structure in the interior of the Earth. There is no accurate way
currently known of estimating the density distribution of seismic data
alone. To come up with a mean density of 5.5, earth models assuming higher
density values for the inner zones of the Earth have been devised. ...
Except for the ocean and the crust, direct measurements of the density of
the inner layers of the Earth are not available. This currently accepted
Earth Model is inconsistent with the law of sedimentation in a centrifuge.
The earth has been rotating for some 4.5 billion years. When it was first
formed , the earth was in a
molten state and was rotating faster than today. The highest density of
matter should have migrated to the outer layers. Except for the inner core,
which houses the engine, powered by a nuclear reaction and which keeps our
planet rotating, The density of the outer layer of the earth should be less
than 3 g cm-3.
Also heavy elements are rare in the universe. How could so much of
materials with such low stellar abundances have concentrated in the earth's
interior?"
Members-
About this last comment. If these dense materials are not so abundant in the
cosmos, then how come they are found all " densed up " in the inner core of
the Earth?
A good understanding of gravity- and what it isn't- is important in order to
be able to speak freely about theHollow Earth Theory.
