<crickets>

Since no one has any counter-arguments then I have shown that there is a way to escape a BH. All you need is another BH to help you out. :showoff:

So do the BHs merge? If so, what mechanism ensures that?

Or does the spacecraft escape? If so, where is the flaw in the current no-possible-escape formulas?

I wasn't trying to imply that at all. xilman was first to post the handwavey explanation of how there is no way to escape. I have no clue what would happen. I am happy to accept that the two BHs will...

For a single BH I have no problem with the standard interpretation. You get stuck, that's your lot, now you get crushed.I don't see where the specific situation of two singularities acting in...

I chose the billion solar mass size because I wanted the temperature, tidal forces, and the luminosity to be negligible, and for the BH lifetime to be considerably longer than the period of...

Wouldn't that break the time-reversal symmetry? We would have to know the past of two BHs before we can determine the shape of the EHs.

You might be right, but how? Each singularity has not entered the zone of no return of the other. What mechanism will prevent them from departing? If they had a relative passing velocity of say...

Also the time to reach the singularity, in this case about 4.3 hours, would also be different. Since the spacecraft wouldn't be moving towards either of them.

We have two giga-Sun-Mass BHs, A and B, on hyperbolic trajectories toward each other but with the paths slightly offset so they won't directly collide.

I have positioned my spacecraft precisely at...

"not peer-reviewed" so perhaps no so after all. So many theories, so little evidence.

For sure space can be said to be big, but there is no evidence to show that it is infinite1. My current lack of understanding with infinities is of the very small type associated with black holes.
