maybe, but i dont think they should be described as "black" either. because their gravitational pull is soo great even light itself cannot excape, there for it apears bright in the sky.
-
...I personally think Black Vacuum would be the best option.

"Black hole" is more of a name that stuck than a description. Insofar as we talk about a singularity in spacetime I think it is aptly named. Although, what you call "black sphere" may already have a name: there is the Schwarzschild radius (sometimes event horizon): this is the radius around the black hole where escape velocity = speed of light, i.e. the point of no return. The black hole itself is smaller, a collapsing star reduced to a singularity.

it's actually more a hole than a sphere. however there is a sphere like phenomenom that occurs around the hole, the point of no return, in which the gravitational pull exceeds even the speed of light and from which point the further in to the hole the stronger the effect increases until even light and time itself cease to exist. it's a complicated idea, and what we know of black holes are all theories as it is, at least now, impossible to even get close to one. but the theories are based on logic and by what we do infact know of gravity and its extreme power. the hole does have a convex shape, in some regard, however you can't see a cone like shape extruding from the other side. this is were it gets skethy and the way light curves around it, it's impossible to every truley see a black hole

Not really. I think you're thinking of a black hole as a big black round thing, but black holes are really more like very heavy dots. We don't really know how big they are but they are truely tiny. General Relativity says that they should be zero sized, but probably quantum effects come into play before you get that small. What people talk about is the event horizon - this is the point beyond which all particles' futures lie inside the event horizon - i.e. there is no escape - this can be some distance from the black hole. So far, in fact, that for a very massive black hole you can theoretically pass the event horizon without even noticing!
-
I think that would be correct. A black hole is defined by its event horizon, and that is spherical for a non-spinning black hole. If the hole is spinning fast, the event horizon is more oddly shaped.

Think of this: You are looking at a trampoline. Pretend this trampoline is space. Put a stuffed animal on it. It hardly goes down at all. Place a cinderblock on it. It sinks down very far. Put an elephant on it. It doesn't stop sinking down for quite a while(let's just say it's a baby elephant and it somehow left the trampoline without damage) This resembles a black hole. It's gravity is so massive that at the event horizon, a certain distance from the particular black hole, not even light can escape it's pull. Now just think of the impression in the trampoline being there without the elephant. This is a black hole. Basically a dent.

No, not better. It may be more like a sphere on the inside but the colour is unknown. The reason why we call it a black hole is because gravity is so strong than light can not escape from it. So I think hole describes it better than sphere.
-
A sphere is just an approxamation - it would better be termes a tear or anomaly. An unlikely escape is best.
-
Nope, I think that turbowrays car, would be a better description, things go in, never to be seen again tee hee!
