Hey OP what the fuck does this mean

What

>>11207481
Basically, I want to know if it's possible to align the interior of a black hole region by accelerating it relative to another black hole, so that it's possible to transmit information from one interior region to another, without having to merge them necessarily. Similar to a wormhole I guess.

I guess this depends on how spacetime curvature is affected by an accelerated mass. If there is some kind of lag, this could be used in this way.

In fact I wonder if it might even be possible to see things inside a black hole from the outside region by using another one to "warp" the interior region in such a way that it doesn't point into a future that doesn't exist yet (and hence is black) but into the other region with matter and radiation you can see. That's a bit wild though.

Specify the force, acceleration should be proportional to mass...or... idk...I dropped out of high school so...

I'm asking because since gravitational waves move at the speed of light, it should also be possible to move a black hole in such a way that the position of the gravitational source isn't at the center of what would be the event horizon as seen the outside region of the black hole, since it takes time for gravity to propagate.

This would also mean that the inside region would be at a different angle compared to a stationary black hole which is more or less straight, or perpendicular to the surrounding space or however you want to call it. Could this create a connection between the two interior regions if one or both are moved in such a way that the regions start overlapping (independently of the black holes merging)?

>is it possible
Is it probable?

Does GR allow for a path to the interior region that doesn't directly lead through the event horizon? Can interior regions "touch" and become connected? Or do those parts explode into gravitational waves or what? That's probably the simplest way to state the two key questions.

>Is it probable?
Except for the cartoony stylization I would think so, given that:

1: spacetime behaves geometrically in these conditions
2: applying this much energy doesn't tear apart the interior regions in some way
3: applying this much energy doesn't necessarily create a new horizon, effectively merging them anyway, but leading to some even more fucked up shit since now there are two black holes nested into an even larger one.
4. similarly, the event horizon of the accelerated black hole doesn't grow in such a way as to make it impossible to not merge
5. gravity propagates at finite speed. I think this is true for accelerating objects, but I could be wrong.

Of those only condition 3 I could reasonably check myself, at least to a certain degree. Condition 2 I could see being the most likely reason this wouldn't work for the same reason worm holes and rotating black holes have unstable regions, especially those which are similar to what I'm suggesting in that they connect parts that wouldn't be connected usually. But this wouldn't be a wormhole in the usual sense which connects two points in what amounts to the same region, not two separate ones like here.

But then what happens? According to GR at least? Obviously I'm not asking for anyone to actually perform an experiment and check. Thinking about this a bit more my best bet might be looking for papers on black hole mergers, that probably answers at least part of the question. So thanks for asking that.
