I'm sorry for anyone bored of reading the threads I've made so far but either I simply do not understand it or I'm imagining the singularity totally wrong. If I'm chosing my words correctly, at the centre of a blackhole is a dimensionless point of infinite density. The thing I have issues understanding is how an object can have infinite density and still exist.

So if we took a billiard ball and compressed it over and over again, it's diametre would approach 0 and it's density would approach infinite. The thing is once it's diametre reaches 0, you don't actually have an object anymore.

No matter how tiny incredibly small something is, it MUST have a diametre of some length... Regardless whether we can measure it or not... right?

I just don't see how you can take an object of some mass, compress it so much that it's diametre is reduced to absolute 0.

Obviously I'm in no position to question anyone as I barely understand anything about physics but I know the equations say this is how it is, but there is a chance the equations could just be wrong? I know we can't observe blackholes so all we have to go on are the equations but has there ever been a case where something has been thought to be true because of equations but later upon observation it was proved that the equations were wrong?

Sorry if I'm not making sense.
