assistant: I agree completely to this point.
No intelligent dinosaurs doesn't follow.  The dinosaurs were wiped out by a
mass extinction event, not by "unfitness."  And so were the amphibians before
them.  I agree an intelligent species would most likely be roughly manlike in
form, but it could be amphibian or reptilian as well as mammalian.  If the
dinosaurs had lived predator-prey interactions and so on would have kept
driving up encephalization just as it later did for the mammals.  And they
_already_ had upright forms that used their forepaws for manipulation -- get
a good look at Stenonychosaurus inequalis or Velociraptor mongoliensis some
time.  I can see an intelligent species evolving from that.
And, interestingly, it's the small cats that are the more encephalized.  The
largest, the lion, has an E.Q. of around 0.6 compared to 1.0 for house cats.
There's much interesting stuff on this in Johansson's "Lucy" (1979).  The
feedback between upright stance (perhaps to look over tall grass), forepaws
freed for manipulation and brain size apparently drove the primates to
encephalize much faster than anything else.  There's no reason the same thing
couldn't happen on other planets.  So far that's the _only_ route we know of
to rapid encephalization -- although of course we're dealing with a sample
size of one planet and really shouldn't extrapolate too much from that!

assistant: Arnold is being "kind" in this assessment. A "dangerous" object
 on a global scale would be 1 or more km in diameter and if it
 hits an ocean (fairly likely since there is more water than
 exposed land ;-) the unimaginable amount of kinetic energy of
 the object would not be even marginally reduced by its passage
 through even th deepest ocean. The only "effect" would be that
 in addition to the several thousand cubic km of material from
 the ocean bottom thrown into the atmosphere there would also be
 thousands of cubic km of water (as steam mostly) injected into
 the atmosphere. Plus the Tsunamis of course.
 Don;t forget that immediately after the impact global firestorms
 break out, the atmospheric temperature rises to that inside a
 self cleaning oven and virtually all vegetation and surface
 structures are destroyed by it.

Write your reply.

assistant: This is correct though the amount of resources devoted to the
 surveys that are in progress are actually very tiny.
 None of the above is correct. We generally discover objects
 likely to make a close pass to the Earth and having the
 potential to impact us only day, weeks, or rarely a few months
 before the pass. The one recently in the news was quite unusual
 in being discovered several decades before the close pass.
 Objects discovered close to the Earth are already in the inner
 solar system and moving much too fast to be easy (or even
 possible) to rendezvous with. We would have no trouble landing
 on an object at the outer end of its orbit because it would be
 moving much more slowly and thus not requiring much boost to
 meet with if the rendezvous point is carefully chosen. We can
 only expect to land rendezvous very modest mass payloads with
 objects in the inner solar system since we are limited in how
 much fuel such a mission can carry. "Nuking" or otherwise
 destroying an incoming large (greater than 1km diameter) mass
 would be very difficult to accomplish and quite dangerous to
 attempt close to the time of impact. If we can get after it when
 it is still a long way (in time and space) away it would
 probably be doable with current technology but if the body were
 close we would be unable to do anything much.
 Asteroid mining will indeed likely figure large in our future
 and while I wish you were right about the time frame I have to
 say I don;t think you are even close ;-) I expect it will be
 50-100 years before we get after any of them.

assistant: a
 On the contrary. "Nuclear winter" is a shorthand term applied to
 a scenario which was first described in connection with theories
 about what might happen if a major global nuclear exchange were
 to take place. The term describes a situation where enough dust
 and smoke is thrown into the upper atmosphere to completely
 obscure the Sun for years. Ins true that in that scenario the
 dust would have been radioactive to some extent but the death
 and distruction caused by the obscuration of the Sun would be
 because of the resulting loss of corp, cooling of the
 atmosphere, death of animals etc. By the time the radioactive
 material settled to the surface all the major damage and death
 would have long since happened. "Nuclear winter" is a term
 al=pplied to the result of throwning truly massive amounts of
 obscuring dust into the sky regardless of the mechanism. It
 could occur from massive nuclear war, an asteroid or comet
 strike of sufficient size or even large scale volcanic activity.
 Radioactivity is not a requirement.
 The Inuit manage to support very tiny population levels in the
 face of terrible (but seasonal) conditions but they do have
 access to fish, seals etc. most of which would be wiped out in a
 large collision. The rest of us are effectively completely
 dependant on such a large and complex technical infrastructure
 to keep us going we would not stand much of a chance even if we
 were able to survive the first few weeks/months of flood, fire
 etc. It might well be true that a tiny population of human
 beings might survive the nuclear winter (and the Inuit along
 with certain primitive tribes in the Pacific etc. would indeed
 be good bets to be the ones ;-) but on a percentage basis it
 would be very tiny indeed, probably thousands or perhaps a few
 tens of thousands of individuals.

     Read my statement above - again.  The expansion of spacetime occurs
_between_ the galaxies.  It could also occur in galaxies, but then the forces
between atoms is such that the matter slides over the expanding spacetime.
Thus, no change in the galaxy itself.  We determine the rulers used by
observations of the matter.  Its physical properties do not change.
Observations of quasars and distant galaxies show that this is true to the
limits of the precision of the experiment.

I think nukes could be safely used in a more controlled fashion. For
example remote land an atomic powered rocket on the asteroid and
gradually guide it out of its presently dangerous orbit. An atomic
rocket has a greater power density than traditional rockets. True, it is
an untested technology but the designs already exist so it could be
quickly fast tracked and scaled up for such a mission. Of course the
danger is a launch mishap and subsequent possible release of fissiles
but the risk may be worth it. After all to launch a bomb or a rocket
engine the risk releasing materials is the same either way.

Rather like a shirt isn't much good at stopping a bullet, especially one

represents a good source of oxygen for the pyrotechnic display trailing
along behind the core.
Would this sort of event clean up in just a decade? I'll accept that it
would be at least that long, but some previous hits have been getting on
for geological timescales, and while a mile wide rock isn't as big as
some of them, there'd be a lot to clean up and little around to recover
the fumble. FWIW, there would probably be a new balance of nature,
perhaps 15% oxygen rather than 21%. The new life forms would, naturally,
maintain it at that new level rather than suiting us.

Well, we are regularily hit by rocks from space, but they usually burn
up and the ones that do get through are usually small. The asteroid in
question is unusually large, it being a proper asteroid rather than a
random rock. These near-misses, what sort of size are they? Enough to
