There aren't any (yet),
black holes are still a (strong) mathematical/theoretical concept.
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.

Black holes in science fiction movies are giant, black holes that rotate like a circular saws inwards.

Science at this time can find no end to black holes. They seem to last forever.
the experiment is not to create black holes . the experiment is to see how the big bang happened . nothing will happen to us .sit and relax
yes there is by ian mortensen (Breeze)
Gavity. It has no upper limits. That's why black holes exist.
I assume you mean "black holes". Yes, it is now considered quite certain that they do, indeed, exist. Please note that the properties of black holes in science fiction are often quite different than those of real black holes - basically, whatever suits the author's plot.

stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Currently the best online sites for black holes are: NASA Science - Astrophysics, Hubblesite - Explore Astronomy, and schools - Wikipedia. There is also a clever demonstration/animation of Kerr black hole orbits on 3DKerrBlackHoleOrbits.
To play the harmonica, place your lips on the harmonica and blow or draw air through the holes to create different notes. Use your tongue to block and unblock holes to change the pitch. Practice breathing techniques and experiment with different rhythms and melodies to create music.
