Canterbury Distinguished Professor Roy Kerr gives Black Hole lecture via Zoom
The Royal Swedish Academy of Sciences is awarding the Oskar Klein Medal to the University of Canterbury’s renowned Canterbury Distinguished Professor Roy Kerr.
Canterbury Distinguished Professor Roy Kerr is an eminent mathematician, known internationally for discovering the Kerr solution, an exact solution to the Einstein field equation of general relativity. He will give the 2020 Oskar Klein Memorial Lecture on Friday morning (NZ time), at the University of Canterbury.
In 2019, astronomers captured the first image of a black hole, heralding a revolution in our understanding of the universe’s most enigmatic objects, and proving Canterbury Distinguished Professor Kerr’s 56-year-old solution correct.
The 2020 Oskar Klein Memorial Lecture is titled: ‘Kerr Black Holes have no Singularities’.
Abstract: All proofs that Black Holes have real physical singularities make assumptions about the nature of the matter inside and of certain light rays. It is shown that there are such lines inside Kerr that do not satisfy these assumptions. As an example to show that the behaviour inside the event horizon for real matter is very different from the idealisation of empty Kerr we consider two slowly rotating Black Holes collapsing to a single object. There have been many different approaches used to calculate the collapse of two BHs to a single one. We show that the best starting point is the Kerr-Schild form for a Black Hole. This explains the unexpected accuracy of a calculation by Jose Rodriguez for the first gravitational wave discovery, GW150914. (More at: www.okc.albanova.se/research/memorial-lecture)
Given the travel restrictions, Canterbury Distinguished Professor Kerr will deliver the lecture internationally via Zoom (https://stockholmuniversity.zoom.us/j/63531400896), 8am, Friday 18 December New Zealand time (8pm on Thursday 17 December in Stockholm, Sweden), with a physical audience in Lecture Theatre E5, Engineering Core, at the University of Canterbury’s Ilam campus.
