Is a black hole an actual hole or a very dense sphere?

My idea of a black hole is that it is an incredibly dense sphere. Is that correct? And anything that falls ‘into’ the black hole is pulled onto the sphere and adds to the mass.
So I assume that I would be crushed if I fell into one. But what is going on at the event horizon re: Time and space?

Time = 3.50
Space = Sonic

Black holes do feed and grow - what you're talking about is the event horizon and it's the point at which no information can cross back. There are lots of theories on what happens after the EH but it almost infinitely unlikely that we'll ever know because there isn't any way to get the information back out. I personally like to believe that a different universe exits inside every black hole.
I guess to answer the other part of your question I guess a black hole is like a spherical drain. But I'm no Carl Sagan or Black Science Man so who knows
And now, here is a bear with num-chuks

If a black hole is so dense that not even light can escape it how does that jive with nothing can be faster than the speed of light. Wouldn’t the light have to be pulled in faster than the speed of light?

You’ll have severe time dilation as you approach the event horizon due to gravitational forces but other than that the event horizon is merely the point of no return. Once you cross there is no path for anything to get back out, not even light you emit. You could spend hours or even days traveling before you hit the singularity.

Gravity moves at .8-1.2x speed of light

the laws of physics break down at the event horizon

All light inside the event horizon can’t escape as all paths it could take bend inward. It’s not it getting pulled straight to the center, it’s that it no longer has a path through gravitational lensimg facing outward.

The singularity. Not the horizon.

Do we think those paths get brighter and brighter as more light is absorbed?

it is a singular point in spacetime

We have literally no idea.

I don't know if it results in a sphere, but I think your general line of thinking is correct:
quote:
According to general relativity, gravity is actually caused by a curving of space and time. Since light travels in a straight line through straight spacetime, the curving of spacetime causes light to follow a curved path.
...A black hole is a region where spacetime is so curved that every possible path which light could take eventually curves and leads back inside the black hole. As a result, once a ray of light enters a black hole, it can never exit. For this reason, a black hole is truly black and never emits light.

Atoms are mostly empty space. I think of a black hole as a place where all that space has been crushed down. For example if the earth was as dense as a black hole it would be less than the size of a golf ball.
