Nah, rocks of significant size are moderately rare. Out at the edge of
the solar system, your average rock tumbles lazily along, and as it
falls in towards the sun it speeds up. It whizzes past the sun and
hurtles back out into the outer solar system, and then stays there for a
long time.
Smaller rocks do indeed pass hither and thither, but we can be fairly
confident that they are not life-threatening as we know roughly when
large rocks have hit in the past and they aren't common at all. If they
were, we'd not be here.
There is no way to avoid a large rock from outside the solar system
which decides to hurtle in at high velocity and just happens to hit us,
but there's nothing to suggest this will ever happen.
The large rocks from the outer regions, though, can be observed
moderately well and plenty of warning acquired. Also, we can do rather
more about them before they get in too close. Once a mile-wide rock is
entering atmosphere, it's too late and we all fall down. A mission to
drop proximaty nukes in front of an oncoming asteroid is perfectly
feasible, even if it has to be a suicide mission (if you're gonna die
anyway, why not save the world doing it?).
Orbits being what they are, even a fairly light explosion will change an
orbit enough to ensure a miss. A hit is rare, and anything on course
will be on a different, missing course if disturbed even slightly in
speed or direction.
FWIW, the first attempt to stop the rock would be a high velocity
unmanned nuclear vehicle with a computer programmed to home in on the
rock and explode near it. If that failed, we could send a volunteer crew
in a shuttle stuffed with supplies and enough fuel to get up to speed
carrying a few nuclear devices so that a hit is certain.
The threat is real, but it's not as hopeless as some might say.

Write your reply.

assistant: It looks now like the Universe is open -- will expand forever, getting less
and less dense overall.  After a very long time all natural stars will go
out.  After a still longer time everything will have been swallowed by
globular cluster, galaxy or galaxy-group black holes.  After still longer,
Hawking radiation will turn the giant black holes into sprays of particles.
The ultimate fate of the Universe is a bunch of isolated particles tending
toward lower and lower density with time.
For non-scientific reasons I believe the Second Coming will happen some time
before that and that the natural history of the Universe will then be
interrupted.

 would only impart an extremely tiny blueshift. The shift would
 not be observed since detection is hard enough examining entire

assistant: Arnold G. Gill said the following to MIKE ROSS on the subject of
Are atoms expanding? (28 Mar 98  10:01:12)
Yes but this last neglects to account that distant galaxies appear as
they were when much younger in the distant past and that, due to their
lack of evolution, they may be very different physically from our nearby
ones (Tinsley). Quasars could be but a phase in that evolution.
Measurements made at the limits of the instruments can be off by an
order of magnitude. The meaning of the word "precision" is rather
interpretative in this case and must be used with caution.
I have shown you an example of how it was possible for atoms to expand.
However, you still haven't clearly demonstrated why not. You haven't
even shown qualitatively how my example doesn't work except to say it
doesn't work.
Simply nay saying is not a good enough answer to satisfy my curiosity.
"Read my lips" is not an objective answer. Please, tell me why you are
so sure the meter stick is not connected to the cosmological?

assistant: Ian Smith said the following to Barton Paul Levenson on the subject of
our moon (29 Mar 98  16:53:18)
Yes, it does! It rotates completely around its axis once every 27.32
days compared to a fixed background of stars. The only thing is it
also goes around the Earth once every 27.55 days, so that together
with the Earth's 1 day rotation we always see the same side but with a
retardation in moonrise of about 50 minutes per day towards the East.
From one new moon to next new moon it all adds together as 29.53 days.
The Earth-Moon system are in a tidally locked and synchronized orbit.
The distance to the Moon varies by about 50,000 km from the furthest to
closest appoach so that its size appears to vary slightly by about 10%.
Charon is almost the same size as Pluto. Pluto has a diameter of
about 2,445 km and Charron is about 1,199 km in diameter. It orbits
Pluto in about 6.3 days and because Pluto also rotates on its axis in
the same amount of time, they make up a unique fixed-pair system.
The moon Charon has been resolved and it is a sphere too.

Listen, we've only just barely made social progress which brought us
from sacrificing virgins, land ownership by barons, institutionalized
slavery, women suffrage, and free speech in a scant few thousand years.
I mean not even 60 years ago we were cramming people into ovens.
I imagine that if a civilization has had 4 billion years in which to
evolve its societies, it would almost certainly consider us
insignificant animals by comparison and would have likely nothing in
common with us socially. We being much more loathesome to them by
comparison than the barbarian hordes were to the Romans.
They may view our technology as we view chimps feeding by using a stick
as a tool in collecting ants from an anthill colony. Their motives for
existence wouldn't coincide with ours by a longshot. However there is
hope in that we may at least have some common ground in the most basic
of fundamentals which make up our subjective sensibilities. Art, music,
poetry, love, play, curiosity, etc... which we also find to some extent
in animals. That means they may easily confuse humans with our animals.
Or, we've been declared a galactic quarantine zone. Perhaps instead a
galactic state park game reserve. Or by fluke they missed us or we're at
opposite ends of the Galaxy.
