Probably not, but there are some interesting if highly unlikely theories.
there is no exact answer, different black holes have different speeds, but all black holes can crush 1 tonne of metal into a size of a pebble
No
Black Hole simply cannot be destroyed because Black holes have so much Gravity That even light cannot pass or go from near the black holes. Black Holes pull the object passing from 10,000,00 (10 Lakh) away from them. So nobody can go near them to destroy it
you go to a hole that's black and tell people about it.
It depends, Black holes can go from being microscopic to supermassive black holes that entire galaxies revolve around. It all depends on which black hole and which quasar.
No where. Black holes eat up every thing around it, including light. It just become part of the black hole. Hope this helped, WoodWorkingMaster
yes, but by the time they do they will no longer be rockets.
Can black holes alter time? Probably... I mean a black hole interfears with time and space... maybe... just maybe.... we could go either to the future or back to the... past.
After consuming all nearby matter, black holes continue to exist in space but may not be actively consuming more matter.

Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
1). Stick a pencil into the object. Make a note of the direction in which the end of the pencil is pointing. Go away for a while. Come back after some time has passed. Make note of the direction in which the pencil is pointing now. If the direction in which the pencil points has not changed, then the object most likely is not rotating. Go to section 2.If the direction of the pencil has changed, and the object has not been disturbed since your first observation, then the object is rotating.2). If the direction of the pencil has not changed, remove the pencil, and stick it into a slightly different place on the object. Repeat the test, using a slightly different interval of time between observations. If the pencil again does not change the direction in which it points, then the object is not rotating.(Second test-run eliminates the possibility that the pencil was originally stuck into a pole of rotation, and the possibility that interval between observations could have been exactly a whole number of periods after the first one.)
