Re­mov­ing the im­pos­si­ble

For 70 years physi­cists have strug­gled over clas­si­cal black hole the­ory; con­cern arose from con­tra­dic­tions with tenets of physics like the in­for­ma­tion para­dox. De­struc­tion of data

The in­for­ma­tion para­dox made fa­mous by Stephen Hawk­ing de­scribes the de­struc­tion by black holes of data and facts about the stuff of the uni­verse. Tak­ing it to the grave Hawk­ing ra­di­a­tion showed black holes should give out low lev­els of ra­di­a­tion. This also high­lighted they are los­ing mass and will even­tu­ally die, tak­ing any trapped in­for­ma­tion with them. Leak­ing in­for­ma­tion

This para­dox can be avoided by re­mov­ing the in­escapable sin­gu­lar­ity with a less com­pact gravas­tar vac­uum bub­ble which could al­low in­for­ma­tion to leak out over time.
