The article was completed by colleagues from the Universities of Cambridge and Harvard and focuses on the paradox of black hole information.
British scientist Stephen Hawking died in March and left incomplete an article on the paradox of black hole information. The work was now finalized by physicists who accompanied the scientist and was published for consultation.
The article focuses on the physics theory called "Information Paradox" which seeks to explain what happens to an object consumed by a black hole. This theory was present in the life of the scientist for more than 40 years, a puzzle that had been initiated by Albert Einstein, when he published in 1915 the Theory of Relativity. Einstein predicted that black holes could be defined by three characteristics: mass, charge and rotation.
Stephen Hawking added the temperature to the equation. The scientist argues that hot objects lose heat in space, the fate of black holes evaporating and disappearing. This creates a paradox, since according to quantum rules, information is never lost. According to Malcolm Perry, one of the study's collaborators, The Guardian, when an object is dropped into a black hole, it tends to disappear, but the team looked at the document to show how at least part of the information can be recovered.
