dont mind "feel good", he has no idea what he is talking about.
We assume, and the theories predict that singularities exist.
The existance of black holes, nutron stars and the like
show what the theory predict, and so we can assume that the theories are correct.
a singularity is really not a single point, it does have size(sort of). However that size is not measured the same way we measure other things, and can be thought of as a single point. Think of it this way, an atom is made up of protons, neutrons and electrons. However they account for a tiny tiny fraction of the volume of an atom. Therefore theoretically you could condense many billions of atom parts into the space occupied by a single atom. When you have enough mass to cause such a collapse (such as in a black hole) the mass of the star is squished down into a tiny tiny fraction of its original size.
Also remember that neutrons and protons are themselves made up of quarks which are very much smaller again.
Now because of the extreme bending of space around this mass a distortion of what we think of as size occurs, and when you start talking about distorted space time all sorts of weird things happen as a consequence. One being that the mass is concentrated in what we call a singularity, and we define it as having no dimentions. (although different theories pedict a one dimentional line or a two dimentional sheet)

In the same way in electro statics we make calculations using "point charges" where we assume that a charge is a perfect point. We know it actually has a tiny volume but it makes the calculations easier and for all intents and purposes the answers come out the same.
Another example is gravity, when calculating the mass of the sun and planets we assumer the mass is all concentrated in one spot (a sort of point mass) but once again this is just for ease of calculations. The answers come out the same either way,
so a bigger black hole will have a singularity which is the same "size" and just more "powerfull" if you will.
if it is hard to grasp dont worry, you are talking about something that is very foreign to our everyday experiences.

***Some people below me read my answer and don't know what I'm talking about, don't understand it. Many of the things that have been predicted by the mainstream WILL be found in space, but not for the same reasons that they were predicted. One of the current "laws" is that the charge on an electron is constant, but there are many examples we've witnessed that allude to the contrary. There is evidence that an object's redshift may not actually tell us its speed (and therefore its distance).

Check out this site before you make up your mind. Go through the archive and read some of the articles, and understand what they're talking about. Our ancient ancestors talked about massive lightning bolts and comets flying in and ******* everything up. Our ancenstors claims should have been given a little bit of credit the moment we discovered Earth had an electric field.***
There is no such thing as a singularity. They are predictions that were made up way back in the day to help explain why the galaxies and star systems could rotate so rapidly without flying apart. Unfortunately, we started seeing examples of this in areas where we couldn't even detect a blackhole, so they had to invent the idea of "dark matter."
Relativity works well in in astronomy and space science because of how it was created. Basically, the scientists took the answers (how the planets revolve around the Sun, the Mass of the planets and stars, how the stars and galaxies move) and created an elegant series of equations to explain them all. They believed their equations to be correct because this is what they were observing, so it must be true right?
Well no, as we built better telescopes we began witnessing objects and entire galaxies moving far too fast for their observed mass, defying the equations and defying gravity! It wasn't light pressure robbing these celestial objects of a few arc seconds, which is what sprung Einstein to whop up Relativity. Venus was so much of a mystery, but Einstein cracked it, right?
WRONG! If the atom doesn't fit, you must aquit! Electromagnetic forces have been known to cause these very same effects we witness the galaxies doing. If the astronomers can't explain something they see, they blame it on magnetics. Double-helix galaxies, just like our DNA, are floating around out there. That should tell you where you should start looking to explain the molecular and Universal connection.
Venus' orbit is nearly a perfect circle, and it spins the other direction very slowly. It used to be called the hairy planet, the smoky planet, and bearded planet. It's latin name means morning star. It was literally glowing! I'm sure some electromagnetic stuff was going on with it, and that would help explain it's brand spanking new surface.

Mars got blown the hell up. That's a start on finding out about it right there, google should take you the rest of the way. Hope this helped you understand why singularities will never truly be discovered. Relativity was based on a few wrong assumptions.

I have no idea what Mr. Feel good above is talking about. He offers some true comments about dark matter at the start, but that didn't have anything to do with your question about singularities (singularities are NOT a theory that was replaced by dark matter). And his attempt at disproving relativity didn't seem to go anywhere either. And DNA-shaped galaxies??
Anyway, as I understand it, singularities have a specific amount of mass, but no volume. So although all singularities have the same size (ie. no size), they have different masses. And different masses make for different event horizon sizes.
As for your question about existance- does something with zero size "exist"? I'd say that's too abstract a question. Obviously it's "there" cause we can see the effects it has on things around it, but whether or not you call something with no size "existing" is up to you.
That's the best I can do for ya. Good luck

Yes, there is a singularity in existence. A black hole is one. It does not have a size, and if it did, it would be infinitesimal. Yes, it does bend space and time, it bends more as you get closer. In fact, it is bending an infinitesimal bit right now.
The singularities are the same size and power, for their power is infinite.
Now, your grade point average would have been the same size as a singularity if you did not know the answer to these questions on an astronomy test.

There are things that would make any humans jaw drop if our finite minds were able to comprehend the wonders and the mysteries of the universe. Like another said, although we can't see one directly, we can see the effects it has on those things that are nearby it. So we can deduce that there is such a thing. Also I don't believe a scientist that will seriously answer your question would not at least try to use the spelling checker. Don't trust folks who can't spell.
