PI: Scientific discoveries often happen where two or more fields intersect. What is your favourite scientific intersection, and why?
 
AB: I'm a relativist at heart, but an astronomer in practice. The whole schtick of what I do is that those two things intersect. For instance, with the new Event Horizon Telescope we can, for the first time, peer right to the edges of black holes. You can cast that as the intersection of astronomy and relativity; or if you want you can cast that as the intersection of empiricism and theory.

Could Black Holes Have Hair?

Thursday Feb 06, 2014

Perimeter researchers are trying to find out how far one can tweak general relativity and still end up with the universe we observe. Their method? Adding “hair” to black holes.
