No, they don't. If anyone in this thread is missing the point, IMO it's you. Nowhere, because the quantum system in this case only...

Ah, I see. So this is not the "orthogonal foliation" notion of distance, or the "odometer" notion of distance. It's the other one from...

Any curve whatsoever that is orthogonal to an Eulerian worldline must have a zero ##t## component in the standard warp coordinates...

No, because there's no white hole horizon, any more than there's a black hole horizon. It's just outgoing radiation. The portion of the...

Yes, you're right, I was too pessimistic there. However, any such geodesic orthogonal to an Eulerian worldline would have to lie within...

Any curve in a surface of constant time in the warp coordinates, and only such curves, are orthogonal to all Eulerian worldlines. That...

If you mean in the supposed "vacuum" region, that's kinda sorta true--the "hole" becomes effectively de Sitter only at very small ##r##...

The thread topic has been sufficiently discussed. Thread closed.

No, it can't. That was already pointed out in post #2 of the thread.

Moderator's note: I have moved all of the posts from the second thread @DanteKennedy started on tunneling, into this one.

In a Bardeen black hole solution, there is no information paradox because there is no true event horizon anywhere. The causal structure...

Yes. And in the back wall, Eulerian observers asymptotically get "peeled off" of the wall and released into the region behind the bubble.

Yes, agreed; in the scenario in Figure 3 of the paper, where the bubble stops once it gets to Alpha Centauri, it can be escaped then...

And in that previous post I basically rediscovered what's presented in section 5.5 of the paper that talks about the event horizon. What...

I think I might be getting at something similar here to what the paper discusses in section 5.5 about an event horizon. That section...
