We do not actually know what is happening within a black hole. It is clear that the currently accepted theories of Physics cannot explain what exists within the Schwartzchild radius of a black hole (and the Schwartzchild radius, or event horizon, is much larger than a point). There are some interesting new theories, but it unlikely that we will soon be able to place instruments near enough to a black hole to test these theories. Once the Large Hadron Collider at CERN is up and running, it may give us some data which will help to test these new theories.
Not much. The whole point of a black hole is that a lot of matter is concentrated in a fairly small space. The Schwarzschild radius of the Earth - i.e., the size into which it would have to be compressed to become a black hole - is less than 1 cm; the Sun would have to be compressed into a sphere with a radius of about 3 km. In general, the Schwarzschild radius is directly proportional to the mass. In a real black hole, the Schwarzschild radius corresponds to the event horizon - the point of no return.
No, that is not likely to happen. At some point, a significant part of each galaxy will be absorbed by the supergalactic black hole in the center; but it is impossible that those black holes all come together, considering that most galaxies are moving away from one another.
A black whole is made from a star which has gone supernova (a massive explosion, then implosion), and this star needs a minimum amount of mass before it can actually become a black whole. The smallest star that can possibly make a black whole is a baby blue giant (roughly 300 times the size of our sun).
Assuming standard (pure, clean) water, and standard temperature and pressure,the density of any amount of water is always 1.In order to find the density of a substance, you don't need to know mass or volume.You only need to know what the substance is. That's the whole point of 'density'.
No, a part or slice of a substance will have the same density as the whole piece, provided that it is made of the same material and has not been altered in any way (e.g., through changes in temperature or pressure). Density is an intensive property, meaning it does not depend on the amount of substance present. However, if the slice is mixed with another material or if its temperature changes, its effective density could differ.
To round density, you would take the given density value and determine how many decimal places you want to round to. If rounding to the nearest whole number, you would round the density value to the nearest whole number based on the decimal point.
Yes. That's basically the whole "point" of black holes.

Of course you can the whole point of the black market is that it's illegal and when you do get arrested you will be sentenced to a long time so best to get out while you can.
Black holes are extremely dense, with a mass packed into a very small volume. Their density is much higher than that of other celestial objects in the universe, such as stars or planets. This high density is what gives black holes their intense gravitational pull, which can even trap light.
decimal point
The average population density for the whole world is approximately 58 people per square kilometer.
5.43 gr/cm3
yes
it is determine in term of density . it is the ratio of density of water to the density of milk . cow milk density is 1.0032
A parabola is NOT a point, it is the whole curve.
The decimal point seperates whole numbers from fraction of a whole number
