The modern theory of gravitation is Albert Einstein's theory of general relativity. This theory describes gravity by relating the differential geometry of spacetime to the energy momentum stress and pressure properties of the matter it contains through second order coupled nonlinear differential equations called Einstein's field equations. An exact spherically symmetric vacuum solution to those field equations is the Schwarzschild solution. If the matter in space is compacted under a radius proportional to the mass contained called the schwarzschild radius, the schwarzschild solution is then referred to as a black hole. Should this happen general relativity predicts that the matter will fully collapse and the schwarzschild solution describing the spacetime can be shown to describe two external regions connected by two internal regions. A theoretical spacelike hypersurface connecting the external regions is called a wormhole. In the case of a Schwarzschild black hole one can not transverse the wormhole fast enough to avoid intersecting the matter that has collapsed and so this kind of wormhole can not be transversed, however the solutions to Einstein's field equations for charged and rotating black holes have external regions that are theoretically possible to reach from ours without intersecting the singularity.
No one knows; you would be crushed before you even got to another end - if there was one. Some say that you can go to another part of space-time thus, i think, worm holes are possibly related to black holes.
Probably not. Or let's just say that wormholes are very speculative. You'll encounter them more in science fiction stories (where it may suit a particular story plot!) than in serious science.
Black holes do not die but they can evaporate.
The most massive stars will die as black holes.

No,
there two different things
they look like worm holes but even bigger. they are in space
Worm holes have not been discovered.
True
it is theorized that it is possible for black holes to act as worm holes but most scientists believe their gravitational pull is simply too powerful for anything to survive being ripped to pieces before it goes anywhere.
You can travel from one place to another , it depends where the black hole starts and ends . you also need a worm hole key
Probably not. The existence of black holes can be considered to be confirmed; the existence of wormholes is highly speculative, that is, they probably don't exist at all. According to String Theory, worm hole does exist. However black holes are not warm holes. Even if you did found a wormhole, it probably going to be only about 1 atom small.

the caforlian black worm has
Something similar to a black hole but with an exit would have to be a worm hole. worm holes are only science fiction (because they have not been proven to exist) although many people believe when entered they will transport you through many light years of space.
