Query: Newtonian black holes: Particle production, "Hawking" temperature,
  entropies and entropy field equations   Newtonian gravitation with some slight modifications, along with some highly
simplified ideas from quantum field theory allow us to reproduce, at least at
the level of back-of-the-envelope calculations, many results of black hole
physics. We consider particle production by a black hole, the Newtonian
equivalent of the Hawking temperature, and the Bekenstein entropy. Also, we are
able to deduce Newtonian field equations from entropy. We finally study
higher-order Newtonian theories under the same assumptions used for ordinary
Newtonian theory. In a companion article we will look at entropic forces for
various entropies and make contact with our analysis of higher-order Newtonian
theories.
