Perimeter researchers try 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.
The international EHT research team, including Perimeter’s Avery Broderick, have measured the magnetic fields that contribute to black hole growth.
Could black holes be the universe’s own accelerator experiments, churning out signals that may unveil exotic new particles – perhaps even the elusive dark matter?
