 O.K. thanks

 Then it must apply that when we measure the s of l we are not necessarily
getting a correct answer. If so then how can we possibly tell what in reality
is the speed of an object receeding from us?

Well...  Radio creates electro-magnetic waves according to _all_ the tech
publications, and radio is the longer wavelengths of the same spectrun as
light.  It is easiest to treat the long waves of radio through their wave
nature, and the short waves of visible light through their particle
nature, but they are all instances of the same photon wavicle.
There is a mathematical relationship between the index of refraction,
the dielectric constant, and the speed of light through the different
glasses, crystals, and plastics.
Cherenkov radiation exists, and is caused by the lower speed of light in
dielectrics.

assistant: Hello James.  UT is defined as mean solar time of the Greenwich Meridian.
GMT is also called UTC, Co-ordinated Universal Time.  UTC, an SI time
definition, varies within 0.9 seconds of UT because of random fluctuations in
the Earth's orbit.  Whenever UTC wanders away from UT by more than 0.9
seconds, a leap second is added (or very rarely, subtracted) to bring the two
back into close synchronization.
   So, for all practial purposes, UT and GMT are the same thing.

 That does not mean to say that that is the age of the universe.
 I have! There is no logical connection between the age of the universe and
our ability to see unless we are able to see further back in time. How far we
can see is physics related to our ability to construct lenses. The only
connection is that obviously we cannot see something which is not/was not
there.

Write your reply.

assistant: Well, your half right ;-) You can't escape the Earth using a
 hovercraft. However there are 2 reasons for that. #1, the
 hovercraft design generates lift by containing the air flow
 inside the skirt which must be close to the ground to work
 properly. Thus a hovercraft's maximum altitude is defined by the
 skirt geometry and and fan capacity and genrally it can't lift
 itself very high. #2, the hovercraft drive works by circulating
 surrounding air into the skirt using a fan and hence can't work
 outside the atmosphere. A rocket is designed differently and
 works at any elevation and in the absence of an atmosphere. As
 long as you can keep providing power to move you away from the
 Earth you can escape it. You only have to be at or in excess of
 the escape velocity if you pkan to shut off the engine and drift
 away froma gravity well.

ABOUT Chiron? ON 01-26-98  10:48
|------------------------------------------------------------|
I currenly have from my library the "Oxford Illustrated Encyclopedia of
the Universe"
Though it's copyright year 1992, I thought you might still want to know
what it says about Chiron.
        CHIRON: The most distant of the objects classified as asteroids,
        discovered by the U.S. astronomer Charles Kowal in 1977. It's
        orbit has a semi-major axis of 13.69 astronomical units and an
        eccentricity of 0.379, implying that the orbit lies mostly
        between Saturn and Uranus, resembling those of short period
        comets. Because of strong pertubations and relatively frequent
        close encounters with planets, the orbit is chaotic and is
        rapidly evolving. The discovery, in 1989, of a faint coma around
        Chiron confirms that this object experiences comet-like
        emissions of volatile materials; it probably originated in the
        outer solar system and perhaps came in recent times from the
        Oort-Opik Cloud.
Well, I hope that's enough "enlightenment" for you.

assistant: Hyya Steven!
Please forgive the intrusion.
No it doesn't, as you so adequately prove below.  As long as your
propulsive thrust is opposing and greater than the force of gravity,
you will recede from the planet.  As you say, all you have to have is
the fuel source to sustain this thrust long enough and you're in
space!
Escape velocity is the speed-at-altitude where your vehicle will
continue to leave Earth's gravity well _without_ further pushing.
Vehicle efficiency, as I understand it, is a balancing act of getting
the vehicle over the magic number at the lowest possible altitude
without squishing the payload.
Or at any point.  You'd just have to keep throttling back the engines
as the force of gravity decreased with distance.
Cuz black holes are different.  You'll have to talk to the math gurus;
I've been led to believe that Newtonian physics is warped or
supplanted such that you can't even have a rocket in a black hole.
Besides, _something_ has to get out of a black hole or we couldn't see
the effects of its gravity.
Isn't the universe grand?
