The point mass of infinite density where space and time don't exist.
Gravity affects space, doesn't it? But since space and time does not exist at singularity, it couldn't have an affect on the gravitational pull... Now I'm confused... Cata?

Your cousin would be correct.
Really ? I was more leaning to the vodka bottle
Singularity:
The point mass of infinite density where space and time don't exist.

Unless you are trying to say the disc is the point pulling it all in o.o

There is no limit in principle to how much or how little mass a black hole can have. Any amount of mass at all can in principle be made to form a black hole if you compress it to a high enough density. We suspect that most of the black holes that are actually out there were produced in the deaths of massive stars, and so we expect those black holes to weigh about as much as a massive star. A typical mass for such a stellar black hole would be about 10 times the mass of the Sun, or about 10^{31} kilograms. (Here I'm using scientific notation: 10^{31} means a 1 with 31 zeroes after it, or 10,000,000,000,000,000,000,000,000,000,000.) Astronomers also suspect that many galaxies harbor extremely massive black holes at their centers. These are thought to weigh about a million times as much as the Sun, or 10^{36} kilograms.
The more massive a black hole is, the more space it takes up. In fact, the Schwarzschild radius (which means the radius of the horizon) and the mass are directly proportional to one another: if one black hole weighs ten times as much as another, its radius is ten times as large. A black hole with a mass equal to that of the Sun would have a radius of 3 kilometers. So a typical 10-solar-mass black hole would have a radius of 30 kilometers, and a million-solar-mass black hole at the center of a galaxy would have a radius of 3 million kilometers. Three million kilometers may sound like a lot, but it's actually not so big by astronomical standards. The Sun, for example, has a radius of about 700,000 kilometers, and so that supermassive black hole has a radius only about four times bigger than the Sun.
The spatial singularity is the term used for a black hole. Different from a normal singularity discussed by einstin. it happens when matter is compressed to small spaces creating very high densitys. The gravataional pul warps space-time into a sphericle disk. HEnce black hole. THAT IS WHAT A BLACK HOLE IS. Not a point of infinte mass. GEEZ. No one listens to josh.
Thats the truth..... Dude. Its awsome that you are trying to learn, but honestly. Do a google search or something. Anyway.....rock on

Wth... Search everywhere for the parts that make up a black hole. The singularity is part of it.The spatial singularity is the term used for a black hole.

The singularity is a part of it. It's what creates everything else in a black hole, the accretion disk, the event horizon. The singularity ISN'T the damn black hole. It's the center point of it, that creates everything else. That's where the star is/was/will be.It occurs when matter in our universe is compressed to infinitely small proportions, a mathematical point. When this happens, the gravitational force becomes dominant and causes space-time to fold in on itself, creating the spherical event horizon, which separates the singularity from the rest of the universe.

His point was that the spatial singularity that causes the formation of a black hole is not the same as a point of infinite mass; an einstein-defined singularity.

It's a point of mass of infinite density where space and time stop.
Well... It does have infinite mass, because infinite density would have to have infinite mass to help it along. O.o
