Just a query. He mentioned referencing the Bible. It seems to me that this shouldn't be in a science thread.

Alright, ICANT, if you would be kind enough, could you tell me what you think a singularity is?
In your own words, not an definition.
I'll work from there.
​
Can I have a go. This is the picture that I have come away with after reading Greene, Hawking and others.
​
Hawking defines it this way: A point in space time at which the space time curvature becomes infinite. That sounds great and I'm sure it's correct but it goes beyond my understanding so I'm wondering if the following is correct.
​
It seems to me that a singularity is a dimensionless point of infinite or almost infinite energy. If I can go further it seems that particles are pretty much the same thing except with defined amounts of energy.

First of all, I'll begin with what you might call an operational definition of a singularity. A singularity is a point where a physical quantity becomes undefined. Usually due to the appearance of underlying physics not fully appreciated in the model.
​
It seems to me that these statements can be compatible. If it is undefined then it could well be dimensionless. It seems to me that most of the things I have read seem to imply that singularities and particles are dimensionless points but like you say the nearest thing that can be said with confidence is that they are undefined.
​
Is this a reasonable statement?
Thanks for this. Free school!
​
Everybody is entitled to my opinion.
