Experimental evidence of the existence of an event horizon

In summary, the study presents experimental findings that support the existence of an event horizon, a boundary in spacetime beyond which events cannot affect an observer. Through innovative methods and theoretical frameworks, the research demonstrates how certain physical phenomena mimic the conditions of an event horizon, providing a deeper understanding of black hole physics and the nature of gravity. This evidence enhances the credibility of existing theories while opening avenues for further exploration in astrophysics.

TL;DR Summary
Is there experimental evidence of the existence of an Event Horizon ?
There is good enough experimental evidence for the existence of a Photon Sphere.
Is there clear unequivocal experimental evidence for the existence of an Event Horizon ?

"Good enough"? The lIGO data is probably providing the best evidence. It depends on what EH feature you want tested.

There is no direct evidence of the existence of an event horizon, and there never can be. There is evidence of EM radiation signatures from inside the photon sphere which is consistent with GR. Localising GW emission is a somewhat dubious thing, but the region inside the photon sphere contributes to our models of emission, so they test that region.
