Sorry if someone already asked these, but I didn't see anything that was the same. A few of my friends are in a film class and we're working on a little indie movie, and the concept of it is a micro black hole is discovered at the edges of our solar system, and we want to make it somewhat realistic. So I'm hoping to get a bit of input on some of the things here to work on the script and visual elements and make it better. Anyway, I know black holes are usually developed when a star's core collapses, but would there be any other possible cause? As it stands right now we don't really have much of an explanation for it (the script kinda skips over it, basically just says that it's more important to destroy it than figure out why it's there), which is fine since we couldn't find any other possible cause online and someone wants to use it as some statement that I forget what he said. I read that they may have formed during the cosmic inflation, but since that isn't really what's happening in our solar system it probably isn't a very good idea to say that's what caused it. We talked a little bit about it, and someone brought up an idea about a tear in the spacetime continuum linked this time dimension to one during the big bang, thus forcing the black hole to form (I personally liked the one where we didn't really say why it was forming because what he said made absolutely no sense to me). Secondly, to destroy it, the ship drops basically a negative matter bomb close to the event horizon, with the plan that it would force the black hole to evaporate. But if it was dropped, when it hits the event horizon would it still be one object or would it start breaking down within the event horizon? On a side note, if say part of the ship were to run into the event horizon but the rest was out, like an antennae or something, would it be broken off or would it pull the rest of it with it? Another part of the story has them using the ergosphere to flip around, and using the acceleration as momentum for the return trip. So if they were to enter the ergosphere, would radio waves also be absorbed by the black hole and therefore distorted if they broke free from the ergosphere? And outside of the ergosphere, does it have any affect on objects? Could you remain stationary and not be affected by it's gravitational pull, or would you need to be a lot further away? I think I'm forgetting some things that I meant to ask... but oh well. Anyone that can clear this up for me, it would be appreciated.
