Wait a minute. I'm confused on a particular point, specifically the
use of the term "density".
I was talking gravimetric density because you were talking
gravimetric separation. Inertial mass density is a different thing.
Hypothetically speaking, if we were hanging
out in outer space somewhere far away from any large gravitational
body AND if we had three equivalent sized balls containing, oh, let's
say the element lead. If lead ball one contains 100 percent normal
matter, if lead ball two contains 50 percent normal bound matter & 50
percent mirror matter bound within the nucleus of each atom, and ball
three contains 100 percent mirror matter...
Now... wouldn't all three lead balls be perceived as essentially
indistinguishable from each other by our own senses?
Gravitational tests with pure mirror matter present an detectable can
provide very very sensitive tests - unlike the case where all the
matter has positive gravitational charge. Very slow drift rates are
easily measurable. I'm not sure how to answer that question without
very careful analysis. I can tell you for sure that the three balls
would be quite distinguishable anywhere in the vicinity of our solar
system.
The ball that is 50 percent mirror matter would have twice the
inertial density of a normal ball, and no weight. The high inertial
density of such matter makes it bad for long range space travel and
excellent for earth to orbit vehicle structural use.
If we were to
push against each of the lead balls floating in outer space with the
same amount of force wouldn't all three -resist-our pushes with the
same amount of inertia?
You are confusing inertial mass with gravitational mass. Negative
charge gravitational mass still has ordinary inertia.
If that is accurate assessment I don't understand your use of the term
"low density". I tend to interpret "low density" as meaning matter
containing atoms with either a smaller atomic number, or perhaps a
crystalline structure less densely packed.
BTW, I had not even considered the possibility of both normal and
mirror matter (protons & neutrons of both type) combining in various
percentages within the atomic nucleus. Jeez! That ought to complicate
the classification process big time!
Not at all with regard to the elements. As I said, the bond is very
weak, sub-volt binding energy. A centrifuge can do the separation.
I can not imagine what the
revised Table of Elements would look like.
There is no need for such a thing. The binding is not strong force
binding. A mere centrifuge can pull the stuff apart.
How would the subtle
changes manifest per individual atomic number containing different
percentages of each kind of nuclear material. Maybe we should thank
our lucky stars of the fact that we apparently live in an obscure and
unimportant portion of the galaxy, a neighborhood totally dominated by
one particular kind of matter. ;-)
If the MOND equations are due to mirror matter then there is a lot of
mirror matter in our galaxy, which, BTW, might well not be the Milky
Way, but rather the Sagittarius Dwarf Galaxy. Our solar system may
take a polar route over the top of the Milky Way, in which case it
has been bathed in a pretty good bath of the mirror matter. See:
http://viewzone.com/milkyway.html
Besides, we might be manufacturing the stuff ourselves, in particle
colliders. A proton-anti-proton collider should manufacture just as
much mirror matter as matter. A very small quantity to be sure, but
possibly a detectable quantity. It may be of interest to attempt
concentration of mirror matter from collider target area parts that
have been in service for a long time. I think there is a much better
chance of a find just looking around at crater sites.
