Is it possible to create an artificial Black Hole? I am quite curious about black holes. Once I just thought whether it is possible to create an artificial Black Hole, i.e. an human made black hole. Also explain there formation if it is possible.
There has been a lot of speculation, whether it's possible with particle accelerators to create micro black holes. This is only feasible, if space is higher dimensional on very short distances. This kind of black holes would be very short-lived due to decay by Hawking radiation. This kind of black holes could be detected by their decay products.

There seems to be no evidence, that black holes have formed in a particle accelerator.

In standard 3d space the smallest black hole needs the energy-equivalent of more than $10^{19}\mbox{GeV}$ of the Planck mass of about $20\mu\mbox{g}$ to form. That's far beyond the energy a particle collider can focus onto a single particle collision.

Even the most energetic cosmic rays are several orders of magnitude below the needed energy.

LHC provided up to 8 TeV (8,000 GeV) for proton-proton collisions, scheduled are 13 TeV for the upgrade. That's 15 orders of magnitude below a smallest 3d black hole, but might allow short-lived black holes for higher-dimensional space. This way LHC can constrain the structure of space on short distances.
