What is Paris Hilton's take on the feasibility of ion propulsion in future manned space missions?

It dosent push against anything. Basic physics. For every action, there is an equal and opposite reaction.

Hot gasses escaping from the rocket motor cause an equal reaction by the rocket in the opposite direction.

There are many ways to look at what happens, and they are all (mathematically) equivalent. Think of the centre of gravity. Imagine a vehicle (full of fuel or whatever else) just sitting there, stopped (relative to some reference).

The centre of gravity just sits there. Shoot off the fuel out one way (using a rocket engine, for example). Because no outside force is involved, the centre of gravity cannot move, therefore, the rest of the vehicle must move the other way, so that the combined centre of gravity (vehicle plus fuel) remains stationnary.

The faster you shoot off some mass in one direction, the more the vehicle must accelerate the other way. ---------- You can go one step further and find the centre of "energy". (Same idea, especially while the vehicle is stopped).

Shoot off some energy one way, the rest of the vehicle moves the other way. Imagine a giant flashlight, stopped in space. Turn it on.

It shoots off light in one direction and the probe accelerates (extremely slowly) the other way. Each photon of light carries a tiny bit of energy, but at extremely high speed (the speed of light, of course) so that -- adding up all these tiny photons -- the vehicle moves the other way, even though the acceleration is very slow. You could not take off from Earth (not even from the Moon), but once in "open space", as long as you have plenty of time...

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
