Answer to my own question.
Brilliant show (http://www.thenakedscientists.com/HTML/podcasts/).
Story idea: Einstein's view of black holes. Presumption he could have been correct, for the sake of argument...
So far as I can tell, nothing observed, so far, requires event horizons. And, event horizons violate causality, no matter that S. Hawking desperately attempts to argue away the fact.
Is there a way, using gravity wave measurements, that the "frozen star" model can be disproven?
In frozen stars, what would happen?

What do you think?

When undergoing gravitational collapse a star's mass will at some point be entirely contained within the event horizon. This does not mean that an entirely smooth sphere is the result of this collapse. There will be an enormous amount of turbulence in the system. Some of the surface of this collapsing mass will be inside the horizon before other bits are. This unevenness during collapse suggests that a frozen star would be lumpy and uneven internally. I am not sure what this would mean in terms of this hypothesis.

Einstein's view of black holes. Presumption he could have been correct
Einstein had different ideas about how to interpret his equations, at different stages of his life.
There is not a single idea about black holes that he held for his whole life.
Is there a way... that the "frozen star" model can be disproven?
The first thing to say is that it hasn't been proven.
The frozen star hypothesis is something that is thought to occur at a distant time in the future, when there is very little Hydrogen gas left to fuse into Helium. However, there is still a lot of Hydrogen in the universe, so normal glowing stars should still continue to appear for billions of years.

Thanks for the link. Just a head's up that your last parenthesis was not included when you highlighted for the hyperlink, so it doesn't go to the right page right away.
