In connection with a discussion on the Blaze Labs Yahoo site, I had
reason to review some of my past departmental note - in particular,
note N21/87. In it I referred to a paper by Hoyle and Narliker
(http://groups.yahoo.com/group/blazelabs/files/HOYLE%20Fred/).
I was re-reading Hoyle's paper this morning when I came across this
bit which is relevant to this thread.
==========================================
"Plainly then, we cannot expect to arrive
a conformally invariant system of dynamics
so long as the mass of the particle is
considered a fixed quantity belonging
autonomously to the particle."
==========================================
I have no idea what a "conformally invariant system of dynamics" is
- but Fred seems to think it is a good thing. 8-) . So if he was
still with us [d.2001] he would no doubt be pleased to find that
mass is a property of substance which does not belong "autonomously
to the particle". 8-)
Another theme towards the end of his paper may be of interest to
certain Vortexians.
=============================================
In this representation...G...is proportional
to T^-1. Such a variation would have a
profound effect on astrophysics and
geophysics.
There are aspects of geophysics that seem as
if they would be greatly helped by this kind
of dependence. Steadily weakening gravity
would gradually release the interior of the
Earth from compression. It can be calculated
that the radius of the Earth would be
required to increase at about 10 km per 10^8
years. There is no possibility of this
expansion being resisted by the crust, which
must be cracked open repeatedly to make way
for new surface material. At all times there
would be an excess upward force on the crust
at the limit of its strength.
The possibility of large horizontal pressure
differences, of order 10^9 dyne cm^2, also
exists, provided in particular regions that
excess pressure is conveyed to the immediate
subsurface by fluid material.
We are reminded in this connection of the
old controversy concerning continental
drift. Our impression is that, while modem
evidence shows unequivocally that drift
actually takes place, the early calculations
demonstrating the need for exceedingly large
forces, really remain valid. If this is so,
we would be inclined to think that some such
behaviour of G as is given by our model
becomes essential for an understanding of
the geophysical evidence.
