One of physicist Stephen Hawking's most famous paradoxes may finally be solved: Black holes may in fact hang onto information about the massive stars that created them, new research indicates. 

 This information may lurk in the radiation around black holes – colloquially known as “quantum hair” – and could, in theory, be retrieved to retell the origins of those black holes, the research suggests. 

These findings, published March 6 in the journal Physics Letters B. (opens in new tab), may finally resolve a thorny problem that Hawking was working on in his last years.
