The Noddy answers are always the best.
I'm just waiting for lightarrow to point out something wrong with such a simple answer.
At the moment I couldn't find anything wrong about it, however let's remember that neutrons and protons are not elementary particles; making them close and close each other will probably result in a "plasma" of quarks and every quark is now more little than a nucleon. What could happen after that...is a total mistery.

it has been suggested that there is a further stable phase between neutron stars and black holes that of a "Quark star"  (google this)  The nucleons have merged to leave free quarks.  however as the size difference between a neutron star and a black hole is relatively quite small  their external properties will be quite similar.

Measurement blah blah position harumph velocity mumble mumble; we all know the score by now.

So, in a neutron star there are all these neutrons (hardly surprising really). They're squeezed together very tightly by gravity; even tighter than Graham Norton and his "friend" at a Village People concert. Now if they're being squeezed together like that, surely it must restrict their movement somewhat. But do they have less freedom of position and velocity than ordinary neutrons at the centre of an atom? Could there come a point where their movement is so restricted by being squeezed together that the Uncertainty Principle either no longer applies or, at least, needs modifying?

They would certainly have more freedom as constituents of the nuetron star, than being confined to a nucleus. And despite the star being very dense, there is still a lot of space on their level of perspectives. For instance, the earth itself isn't very dense - but we compair this density stuff with a quick example.

A spoonful of nuetron star matter would be as heavy as all the cars and trucks of the earth. But theoretically, you could squeeze the entire earth into just the size of a spoonful into an infinite density.

Th nuetron star, as dense as it is, still has a lot of space seperating its nuetron components.
