Note that this is a *popular*-scientific journal where you find
sensationalist wordings, tantamount or close to being wrong, such as
“Black holes are known for their voracious appetites, binging on matter with
such ferocity that not even light can escape once it's swallowed up.”

Instead, a black hole is simply a region of spacetime in which all
worldlines meet in a spacetime singularity; if Sol would be replaced with a
black hole of equal mass, the only mid-term effect would be that the day
would become dark. The river model of black holes (Andrew J. S. Hamilton et
al.) describes this spacetime as space beyond the event horizon falling
faster that the speed of light:

negatve energy particles....
?

A requirement of the conservation of total (vacuum) energy. One partner
of a pair of formerly virtual particles. That which remains when Hawking
radiation is emitted.
