Been catching up reading #astrobites.
Nearly missed this little gem about Penrose Diagrams.
Prof. Sir Roger Penrose did this seminal work in 1963, now, these diagrams are an important tool in #physics when trying to understand causality in general relativity.
Sir Roger continues to do important, interesting, and somtimes controversial work in physics, #maths, #consciousness & #computability.
