Roger Penrose:Yes, that’s true, yes. Yes. Well, it was, I mean, what I did was basically in 1964, so we’re going way back, in which…it was…it was just a little while after the quasars had been observed and people had found this very puzzling. Well, it was a paper in 19...
In the light of his recent (and fully deserved) Nobel Prize, this pedagogical paper draws attention to a fundamental tension that drove Penrose's work on general relativity. His 1965 singularity theorem (for which he got the prize) does not in fact imply the existence of black holes (even ...
Back in the 1960s, Einstein's theory of general relativity re-emerged as a field of important research activity. Much of the impetus behind this resurgence came from powerful new mathematical ideas...doi:10.1007/978-3-319-67819-1_25RoweDavid E....
