what do you think of strong gravitational lensing, the lensing of supermassive black holes M87* and SgrA*as a way to test quantum gravity effects ? does string theory make any predictions of strong gravitational lensing, the lensing of supermassive black holes M87* and SgrA*? could quantum...

"Our theoretical analysis suggests that with advancements in future astrophysical observation techniques, it might be possible to test loop quantum gravity theory using the gravitational lensing effect." LQG makes specific predictions on strong gravitational lensing for the supermassive black...

what would be the reason to To construct a CQ theory of gravity from an existing theory of quantum gravity? CQ theory of gravity is to do away with quantum gravity doesn't string theory posit smooth space like GR?

any chance you could write a paper on Ashtekar variable that by combining Witten's 2022 paper with the 2017 paper by Mahdi Godazgar, one might be able to figure out the "proper method" of quantizing Ashtekar variables would the semi classical limit to GR be easier since arise as a coherent...

could their advanced, technical, mainstream work of quantum field theory be applied to Ashtekar variables in a new way for proposing a fundamental theory of quantum gravity if mainstream lqg is wrong is there a way to quantize Ashtekar variables to create a fundamental theory of quantum...
