assistant: I'm not ignoring them simply discounting them as being of minor
 interest for the types of "back of the envelope calculations I
 am engaging in here.
 #1 is true but relatively unimportant. Iron (of which most of
 the inside of the Earth is composed) is fairly incompressible
 but the "real reason it is unimportant is that compression is a
 process which occurs as atoms are shoved closer together and has
 essentially no influence on the spacings within a specific
 atom.In other owrds the dimensions of an atom are not affected
 to any significant degree by outside compressive forces. That is
 true until the pressure becomes sufficiently great to decompose
 the atoms into the material which makes up a neutron star.
 Pressures at the centre of the Earth are nowhere near those
 levels ;-)
 That's also true but largely irrelevant. At best (from your
 perspective) we would find the artificail BH inhabiting a cavity
 slightly larger in size than we would at surface temperature.
 However the cavity, whatever its size, would be tiny by
 macroscopic standards.
 I do not think I understand what you are trying to say here. The
 BH is not different (except in density) from any other mass. It
 would be moving with the Earth and rotating with it just as you
 and I do. Any 10KM cube of material at the centre of the Earth
 would behave in the same way the BH would in terms of rotation
 and translation.

 to state. If you are disagreeing with the chemical composition
 percentages of the Sun then if we use yours we get the Sun
 containing enough "other" material to construct roughly 2 solar
 systems worth of planets. Same conclusion, different details.
 Namely that it is not correct to postulate that somehow the Sun
 didn't get its fair share of heavier elements ;-)

Write your reply.

assistant: The Solar system probably formed from a Bok globule.  There is nothing to
indicate that supernova events were directly connected to it.  Supernovae may
generate the shock waves that cause star formation, but they are not
necessary for that, or the first stars wouldn't have formed.  They do
contribute heavy elements to the interstellar medium.
There are heavy elements in the Sun -- in fact, there are more heavy elements
there than in all the planets put together.  It's just that the Sun, being
extremely massive, hasn't lost much of the gas that constituted most of the
original nebula.
Current estimates are that 2% of the Sun, by mass, are elements heavier than
helium.

assistant: This Week's Planet Roundup
MERCURY emerges into view low in the dawn late this week. Look just above
the east-southeast horizon as morning twilight begins to brighten. Don't
confuse Mercury with Antares, about a fist-width at arm's length to its
right.
VENUS is the brightest light (magnitude -4.7) in the southwest during and
after twilight. It's getting a little lower every day now.
MARS, quite dim at magnitude +1.2, appears near dazzling Venus this week.
They're closest on December 21st and 22nd, just 1.1 degree apart. (That's
less than a finger's width at arm's length.) In the following days Venus
moves down to Mars's lower right. Try binoculars!
JUPITER shines brightly (magnitude -2.1) 17 degrees to the upper left of
Venus during and after dusk. It sets around 8 p.m.
SATURN, in Pisces, glows at magnitude +0.7 high in the south during early
evening.
URANUS and NEPTUNE (magnitude 6 and 8, respectively) are in the background
of Venus and Mars.
PLUTO is very low in the southeast before dawn.

 In that case if black holes were part of the original formation of the

Write your reply.

assistant: This might be possible in theory, I think, but I suspect it would probably be
even more difficult than building a BH out of charge.
One thing I don't have a good handle on yet is the required energy to
ssemble
the charges.  One potential clue - the irreducible mass of the sort of black
hole I was talking about is 1/2 the total mass.  (It's possible to extract
energy from a charged BH by dropping charges into it, but one cannot reduce
the BH mass below the irreducible mass by this mechanism.)  So far I haven't
seen anything that gives the total energy required to assemble the charges
and/or the potential of the black hole formed by this mechanism.
When we have the resources to build a BH, even a small one, we probably won't
be facing an energy crisis, though it is possible to extract energy from
matter falling into a black hole (in theory).  There's some details on one
mechanism in "Gravitation".
