Three White dwarfs in close orbit equal one BH.This was reality 18 billion LYs ago.Density was in the further back in time.Matter is losing thinning out as I type Bert


To make a black hole the three white dwarves have to die first. And you will have to get everyone off of the orbiting planets.

By their very definition, white dwarves are already dead. No fusion takes place in a white dwarf where mass is converted to energy. They only shine because of stored-up thermal energy. Any planets orbiting a white dwarf are also long dead, having been stripped of their atmospheres, there would not be anyone there to "get off".
