There is currently great interest in experimental tests of quantum gravity theories. However the EHT may provide the first opportunity for testing quantum gravity. In particular the Chapline-Laughlin -Mazur vacuum for quantum gravity leads to a spectacular prediction: the event horizon for any rotatating compact object has a toroidal topology. if this is the case then AGN jets may originate from the throat of this toroid.
