Gravitational Slingshot.

..
Flyby Anomaly.

..
Gravitational slingshot increases velocity of spacecraft without
expelling propellant or reaction matter. This obviously voilates
newton's third law of motion and flyby anomaly supports voilation of
newton's third law of motion.

Umm neo, gravitational slingshot hardly disproves Newton's 3rd law.

It no more disproves it then when I hit the 8 ball with the cue ball and it
goes flying off at an angle.

No proprellent or reaction matter is expelled.


and flyby anomaly supports voilation of
newton's third law of motion.

Not true. The planet involved changes momentum by an amount equal and
opposite to the change of the spacecraft's. Of course this is
unobservable, due to the enormous mass ratio. Newton's laws are obeyed.

Hey stooopid - the planet slows down as the spacecraft speeds up.
Linear momentum, angular momentum, and kinetic energy are all exactly
conserved.

You are obviously an idiot.
There is a corresponding slow down in the speed of the planet,
momentum is conserved.

Apparently so, but in reality, the new velocity is the vectorial
resultant
of both the craft's escape velocity and the planet's velocity.

The reason why the planet does not actually slow down in reaction
is that the minute amount of energy that it contributes to the craft
is instantly replenished on account of it being in stable gravitational
equilibrium on its orbit. (Remember that force is a function of the
inverse square of the distance between the primary and the planet,
and that the energy induced is directly related to the force at
any given distance.

Instead of slingshotting to accelerate, slingshotting to decelerate
to a lower velocity is just as easy, it suffices to have the craft
approach still parallel to the planet's orbit, but going in from the
opposite direction.

Newton's third law is fully respected.

Take a classical mechanics course and stop being a moron.

This is a simple elastic scattering problem. Conservation of kinetic
energy, angular momentum, and linear momentum come together to either
take away or add to the momentum of the spacecraft depending on what
direction the approach relative to the motion of the planet is.
