Black holes (in the astronomical sense) have never been made in the laboratory.
There aren't any (yet), black holes are still a (strong) mathematical/theoretical concept.
no black holes are stars
they are collapsed stars, that draw other matter in, forming the spirals of galaxies (in theory)
well you wouldn't need any to make a black holes to make binary systems but what do make binary systems are two stars.
They do the opposite, they stretch you.
The existence of miniature black holes have not been confirmed yet. It has been hypothesized that there may be some, that formed during the Big Bang. If they did form, we might see flashes from the disintegration of those black holes, now and then. (A miniature black hole takes much less time to disintegrate than a bigger one.)The existence of miniature black holes have not been confirmed yet.

Black holes are located throughout the universe, often at the centers of galaxies. They can also be found in binary systems with other stars. Some black holes are remnants of massive stars that have collapsed, while others are supermassive black holes at the center of galaxies like our own Milky Way.
No, black holes do not make sound in space because sound requires a medium to travel through, and space is a vacuum with no medium for sound waves to propagate.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
They don't. They never have. They never will.
The black holes found in space? No. An underwater volcano or a split in the seafloor can leak magma into the ocean causing it to instantly cool. This is one way islands are formed. So the volcanic stone may be black, but they are not referred to as black holes.
The closest known stellar-mass black hole seems to be at a distance of a few thousand light-years. Of course, there may be black holes that are closer, but that are not known as such yet.The closest known stellar-mass black hole seems to be at a distance of a few thousand light-years.
