In science:

Adams, Mbonye, and Laughlin conjecture that the cosmological constant is caused by a sea of virtual particles, and that black holes may swallow those virtual particles and thereby accrete energy.
Black Holes Must Die
Adams et al. attribute the unexpected increase in black hole mass in their model to swallowing of virtual particles.
Black Holes Must Die
In the ordinary (no Λ) Hawking process, the black hole cannot gain mass by such processes; the negative energy particle can’t propagate outside the horizon, and if the positive energy particle joins its partner and is swallowed, nothing has changed.
Black Holes Must Die
Of course, if the supernova forms a black hole with mass greater than ∼ 2 solar masses, it will swallow up its innermost material and, thus, most or all of the 44Ti (and 56Ni) it produced.

Accretion Disk Models of Luminous Black Holes
At the high temperatures appropriate to RIAFs, electrons radiate energy much more efficiently than the ions (by virtue of their much smaller mass) and are, therefore, expected to contribute dominantly to the observed emission, while the thermal energy of the ions is swallowed by the black hole.

Nevertheless, physical intuition tells us that the entropy of the hole should have gone up when it swallowed the box of gas.
What Exactly is the Information Paradox?
As we have already seen, it is possible for black holes to give up energy to the outside world both by swallowing material particles of negative energy and by accepting negative energy electromagnetic fields.
