The bottom of a slinky goes into a free fall when you hold it from the top and drop it, the bottom will create a zero gravity effect as it floats in the air. Using a large number of slinky's you could keep a platform attached at the bottom in a free fall state, and if you stood on this platform your balance system might feel like its falling or floating.

I'm confused are you saying no pope?
You do not know what "nope" means? That's strange. It is a term of negation. In other words your scheme of a "zero gravity machine" is all wrong. There's no such thing as defying gravity.

That's still not presenting any kind of arguement.

What's to argue? Even with a slinky it should be obvious that the center of mass is falling at the normal rate for objects in a gravity well. It just looks like something strange is going on.

The bottom is motionless because the slinky is a spring and is pulling the bottom upward while gravity is pulling it downward. It stretches until it reaches equilibrium. When the top is released the process is reversed. If you held a string in the same way there would be no upward pull so the entire string would fall at the same rate. Class dismissed.

Free fall is not zero G. It only looks like it from the perspective of those experiencing it. True zero G is something that can only be experienced far outside the gravity well of massive objects.

There is no place in the universe with zero G. It holds galaxies together after all. Zero G really means zero change in acceleration and free fall is exactly that.

In the spaces between the galaxies the universal attraction of distant objects cancels out and space is said to be "flat".

No pope. Even in the spaces between galaxies there is still gravity and if your velocity were zero you'd eventually fall into one or the other. You could say the moon is in zero G since the gravity of the Earth cancels out the gravity of the Sun.

Where space is flat you are embedded in the minuscule gravity of the entire universe pulling from every direction and cannot readily become gravitationally bound to any distant object.

Any gravity is still gravity. You might be in a Lagrange point but you are still in a gravity well. Free fall is no different. Our difference by be semantic and, of course, I'm not anti-semantic. :auiqs.jpg:

Uhhh.... Teacher, will this be on the final?

I'm not sure I like your attitude young man. I may need to speak to your mother. Send me her picture and I'll let you know.

Gravity is not a detectable force like electromagnetism. It's a phenomena caused by the curvature of spacetime near massive objects. It can only be detected by it's effect on mass and electromagnetism. Being all by yourself in flat space there is no way to orbit anything. Applying acceleration in any direction there means you will continue in a straight line until you encounter curved space again. Even that will not happen unless you can go fast enough to beat the general expansion of the universe.

Sorry, kid. Gravity isn't just a good idea, it's the law.
