New Method To Recreate a Black Hole?

Dartmouth researchers proposed creating a new way of reproducing quantum sized black holes in the laboratory. This will enable researchers to study them and verify Stephen Hawking's proposal that black holes emit photons or Hawking radiation. The researchers show that a magnetic field-pulsed microwave transmission line containing an array of superconducting quantum interference devices or SQUIDs, which enables the exploration of analogue quantum gravitational effects.
