What’s inside a black hole? Probing the interior of black holes with gravitational waves

I will present general arguments, based on fundamental physics principles, as to why we should expect a significant, horizon scale, departure from semiclassical gravity inside astrophysical black holes. Then, I will present a simple model which realizes this idea: the frozen star model. I will show that a static frozen star looks exactly like a black hole to an external observer. I will discuss the stability and the spectrum of internal modes of the frozen stars and show that they possess an interesting spectrum of non-relativistic modes and end with an example of how the detection of the emitted gravitational waves during blackhole mergers can test the frozen star model.
