Black Hole Induced Galaxy Existence?

A new scenario has emerged from observations of a black hole without a home, may indicate that black holes may be building their own host galaxy. This may be the long-sought missing link to understanding why the masses of black hole are larger in galaxies that contain more stars. The study suggests that super-massive black holes can trigger the formation of stars
The chicken and egg analogy hence: did a galaxy or black hole come first?

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.
