Perimeter researchers use measurements from the Event Horizon Telescope to test Einstein’s theory with the supermassive black hole at the centre of the Milky Way.

Einstein's theory of general relativity may soon be put to the ultimate test through measurements of a black hole's shadow, says a pair of Perimeter researchers.

The international EHT research team, including Perimeter's Avery Broderick, has measured for the first time the magnetic fields that contribute to black hole growth.

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.

Perimeter Institute is building a team of researchers and students to conduct leading-edge analysis of astrophysical data collected by the Event Horizon Telescope. 


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.
