a black hole is a singularity, size is determined by the "event horizon" or the radius in wich light gets sucked in. a singularity is somethign infinently dense and infinently small. imagine something smaller than a quark that has a mass 3x our son.
it's imposible to know if wormholes exist, unless you can find a way for a ship to survive getting cruched into something infinently dense and ininently small, and still go faster than light speed and come out the other side.

yes infinity is basicaly impossible to reach but it's to the point were it acctualy takes up no space therefore it must have a density = hoververmuchstuffisinit/0 cm^3, that is undefined, and if you think about it the best way to explain it is that 0 goes into the mass an infinite number of times.

ok then take this equation and put it in a graphing claculator:
x ^ -3 now if you want to know this eq is one that goes up to infinity as it nears the Y axis, though it can never reach it, no matter how small the number you plug into it, but it can never equal 0 (or else you get the 1/0 thing going on) also in the other direction the line conitnues to near the x axis but can never reach it either, no matter how high x gets, it just keeps gettign smaller and smaller forever. in effect the latter part of the lin is like a black hole, it has so much mass to it X that it is infinently small, becasue it can never reach 0 so basicaly you get to pick any number and it is smaller than that. EDIT: its acctualy easier to see if you use something like -z x ^ -3 were z is a bigger than one, it make the graph taller, and flips it over x
