well it isnt the year 7000, but i can answer a few black hole questions...
it isnt a warp hole or anything, its a very immense gravitational body so immense in size and density that gravity can within a certain distance draw specs of light towards it... i cant qoute the formula but its the mass of both objects that provides gravitational pull. well its intense to understand that a tiny thing as lightless as... well light could be pulled inwards by such a large gravitational body.
thus why a black hole is referred to as a black hole, cause no light can escape the immense gravity of it. the event horizon is the point at which light itself is drawn towards inwards. and to qoute my grade 8 physics teacher it could crush the world to the size of a pee.
