     They are influenced, but they don't collide because of their great
separation and small size.  By collision, it is meant being substantially
deflected from their path.
     This is completely irrelevant.  First, the spacings of the planets is
much smaller proportionately than that of stars.  Thus, close encounters of
planets in colliding planetary systems (should that ever take place) are much
likelier than close encounters of stars in colliding galaxies.  Second,
electrostatics controls all of the motion on the molecular level on down.
Gravity doesn't come into play - ever.
     No.

From: casca@ASTRO.UMontreal.CA (Serge Demers Secretaire CASCA)
Subject: NGST Science Steering Committee
The Joint Subcommittee on Space Astronomy and the Canadian Space Agency have
been working toward Canadian participation in the Next Generation Space
Telescope mission.  Initial discussions have occurred between the CSA and
NASA, and formal contacts at the scientists level have begun, lead by Simon
Lilly. The board of CASCA has endorsed a JSSA recommendation that an NGST
Canadian Science Steering Committee be established.  The committee will be
chaired by Simon Lilly, and its mandate will include,
1) tracking the development of the science payload on the NGST and the
science access policy.
2) advising the JSSA and CSA on issues related to scientific use of the NGST
by Canadian scientists.
3) solicit input on Canadian desires for instrumentation and capabilities.
4) overseeing the development of proposal(s) for Canadian scientific
involvement in the mission.
5) communicating mission developments to the wider community.
The JSSA solicits expressions of interest to participate in the NGST Science
Steering Committee.  If you would like to serve on the committee please
respond by email to Russ Taylor (russ@ras.ucalgary.ca) before 1 April,
including a brief description of your specific interest in the mission.  The
JSSA will constitute the committee shortly thereafter.
Background information on the Canadian proposal for participation in the NGST
can be found at http://www.ras.ucalgary.ca/jssa/ngst.html.  For additional
information contact Simon Lilly (lilly@astro.utoronto.ca) or Russ Taylor.

People are watching the skies all the time. How do you think this latest
near-miss got into the news? We are often able to see asteroids coming years
in advance.  If an asteroid on a collision course was detected now, we would
probably plan to blow it up.  We have nukes capable of turning a roid into
pieces too small to survive reentry, we have spacecraft capable of asteroid
rendezvous, we have rockets capable of putting them into orbit, all available
on short notice if the emergency warrants jumping a few queues.
A decade or so from now, we will probably have asteroid mining capability,
nd
be able to deal with it in a more controlled manner.

assistant: Hi,
[..]
 O.k. fair enough.
 What was the 'state ' of the earth considered to be at the time of the
collision? Gaseous, liquid, solid?
O.k. well according to the above then the contact was a glancing collision.
If the earth was in gaseous or liquid state at that time then it makes sense.
If however it was solid then it doesn't. A large chunk broken away from the
earth would not reform into a spherical body.
 As you refer to the crust of the earth then logically it was solid.
 Hence that idea holds no water either(IMO)

The EQ is a long-term average.  If the earth had been slightly ahead
in its orbit 65 million years ago, the K-T event would not have happened,
and the Age of Mammals would have been nonexistent or at least
completely different.  If the continents had arranged themselves
only sightly differently, global ocean currents, thus climates,
thus beasts, would have been dramatically different.
I don't think that.  The statistical average rate of collisions
says nothing about any individual splat -- not its date, mass,
velocity, incoming angle, point of impact, etc.  That is the sense
in which there is a tremendous amount of randomness.  But yet,
on average, the EQ could continue to rise.  I'd bet that your
cites (above) show that EQ jumps significantly in the 20 million
years or so after mass extinctions.

assistant: Arnold G. Gill said the following to MIKE ROSS on the subject of
Are atoms expanding? (23 Mar 98  13:51:08)
This is exactly what I was getting at. For example the Sun's influence
on the Earth-Moon system is greater than by each member's on the other.
Take for example in the Earth's gravity field each part of a molecule or
atom is under its influence as a total system. Would the cosmological
influence act similarly on the microscopic?
Assuming an alternative viewpoint in which atoms are pegged to the
fabric of spacetime: If in the universe's history atoms were smaller in
the past then their continuum would have had shorter wavelengths than
those on Earth today.
However, it can be reasoned this difference could be exactly cancelled
by the cosmological redshift and we wouldn't be any the wiser why atoms
appear the same in the past as in our local space. How does one go about
proving this discordant idea is utterly wrong?

Write your reply.

assistant: Hi,
 Thankyou for clearing that point up in my mind.
 I would like to point out though that (accepting the above)
the amount of material 'splashed' would have to be enormous relative to the
amount of material in the earth.
 If the collision was head on, i.e. against the natural orbit of the earth,
then the majority of the material splashed would fall back onto the earth,
more so than if the collision was with the orbit, i.e. from behind so to
speak.
 In either case, much of the material, I have been told as much as 80 to 90%
would still fall back onto the parent body.
 If this is so then the amount splashed off would not leave behind, even with
the addition of the material of the object that hit the earth, the amount of
material we have at present in the earth. What %age of the earth is the moons
mass?
 Another arguement I have heard against the idea which appears to me to make
sense, is that the material splashed off in all directions would have no
reason to reform into a spherical body, it would cool very quickly and form
many small asteroids.
 Could you give me your thoughts on the above please.
