And where is the Sun during this time? Asleep?
Why was the object THERE in the first place unless
because of the Sun's gravity pull? What OTHER
pull is it responding to that it wants to leave? Greg's
explanation is only a neat math equation that
balances various other neat equations put together to
describe the motion humans observed in the solar
system. They ASSUME an escape velocity exists,
because this makes their math neat. In all fairness,
they have no reason to think otherwise, except for the
fact that the dirty snowballs they call comets appear
to leave the solar system, picking up speed for NO
reason, after having pulled close in to the Sun.
Apparently, the comets studied math in school and
are being obedient, in order to get an A and a pat on
the head and a job after they graduate.

They TRADE? Do they negotiate before making the
trade, as occurs at the Stock Exchange? Do they
mull this over and can they decline? What
happened to Newton's LAWS? They get to decide
if they want to or not, or are they under a Newton
MANDATE? Can't have it both ways. If a planet
or comet is close into the Sun and then "decides" to
increase its velocity and move away from the
gravitation giant is it visiting, WHAT is influencing
that decision, other than the math Newton used to
DESCRIBE what he was seeing? He did not
EXPLAIN what he was seeing, please note. In order
to explain what he was seeing, he would have to put
forward cause and effect. What is the CAUSE of
the increase in velocity and pull away from the
gravitation giant, and please don't tell us the cause
is a neat geometric formula, as though these bodies
had gone to school and have the math in their little
orbiting heads. They are drawing geometry? What
happened to the Inverse Square law, which should
keep them close into the Sun when they arrive there?
The math only works when you keep it apart? Can't
put your math together? Is that because it is
CORRECT?

In order to remove a planet permanently from the solar
system you'd have to remove the Sun, first. Why would
it LEAVE? What happened to the Inverse Square law?
Took a nap? Hello! Earth to Greg, who is floating out
there in space unable to put his math together. When
you're on a trampoline, you bounce UP because your legs
did their best. This equates to a planet getting bumped
or influenced violently AWAY from the Sun in some
manner. Then the force of gravity stops your "escape"
from planet Earth via your trampoline, and you slow to
a STOP, then REVERSE to return to Earth. This
equates to what the "escaping" planet would experience.
There are many factors that determine what orbit a
planet assumes around a Sun, and all of these would
come into play during such a planetary shuffle, which
HAS happened in the past in your solar system. This
is why your Earth is lopsided. And then there is the
Asteroid Belt, standing as evidence of horrific planetary
encounters in the past. Do you not think your Earth
achieved an "escape velocity" during such an encounter
which put the hole that is her Pacific into her side? Did
she leave the Sun? She was certainly at the "escape
velocity" during that moment! Perhaps she did not
know she wasn't supposed to put her math together, on
the same page, and got confused, listening to the gravity
pull that your Inverse Square law describes. No A for
planet Earth, she flunked the course!
