The purported properties of Black Holes though cause serious problems in showing they exist. You would have to show that particles or other masses entering the BH have the property of infinite clock-maker time to enter the BH horizon. Another problem would be that you would need to show that one could legitimately expect a singularity to exist, but since no observer could report getting to the singularity — since the observer would be supposedly destroyed in the process, and any such observer could not expect to report their findings once past the event horizon of the BH, the theory of BH’s is non-falsifiable.

Sounds a lot like the argument: “I have never been to France, therefore France does not exist. QED”

There is a lot of direct observational evidence that there exist extremely large mass objects in the universe. At the center of our own galaxy, where stars’ orbits have been used to estimate that object’s mass, and its other properties, and closer objects that represent the decaying remnants of stellar explosions.

It doesn’t seem to be much of a stretch to extrapolate that, at some mass, the gravitational pull of the object will yield an event horizon beyond which nothing inside can escape outside.

That the inside of a BH can not be vetted by an observer communicating back to us is not a limitation of the theory, it’s just a limitation imposed by reality.
