A professor from the physics department at Fundan University in Shanghai, China, called Cosimo Bambi, is an Italian cosmologist and physicist, and he proposes sending a ship to a black hole. It seems a bit crazy to send a ship. If it is difficult to send a ship to another star system, imagine sending a ship to a black hole.
The idea would be to investigate what a black hole is in general, to investigate the extraordinary phenomena that happen in their environment, black holes are the product of a gravitational collapse and a lot of amazing things happen around them and I'm not saying what happens inside, we have no idea.
The mission would be a mini spacecraft propelled by a laser and together with another, there would be two, one would go into the black hole and the other would observe what is happening with the ship that is going to go into the black hole.
But we have a black hole nearby, because the closest known black hole is about 1,500 light years away, but it turns out that according to this research there could be a black hole just 25 light years away from us. I think the most complicated thing about this mission that this researcher proposes would be to locate that black hole.
Because keep in mind, that the closest known black hole called Gaia BH1, which is 1560 light years away in the constellation Ophiuko, is inactive and when a black hole is inactive, there is no way to know where it is, there is no way to detect it, except that it is disturbing other stars in its environment, and that is how they discovered this one, because the gravity of the black hole is making a wobble in a star that is close to this hole. black, a star similar to the sun.
So it will be difficult to find a black hole in a range of about 25 light years away, but the question is, why would we have black holes nearby? And here comes a part that interests me and that, mentioned in other publications, in the image we have our stellar neighborhood, the solar system is going through what is called a local bubble, which would be the image in the graph above.
The solar system would be practically in the center of that local bubble, the local bubble is the product of ancient supernova explosions, those explosions have made “holes” in what the galactic gas of the Milky Way, creating that bubble, These supernova explosions took place between 10 to 20 million years ago, although it is called a bubble, it is more in the shape of a shopping bag because it is about 300 light years wide by about 1000 light years long.
We are in an old battlefield, if we had arrived at this place 10,000 million years ago, we would be exposed to a mass extinction due to these supernova explosions, luckily, we have arrived a little late, but now we are in the middle of this ancient battlefield.
The question is where are the “corpses” of those stars that exploded, because a supernova is caused by the explosion of a massive star, its outer layers are thrown off and the core normally collapses into a neutron star, but if the mass of the core exceeds the Tolman Bheimer Volkov limit, estimated to be between two and three times the mass of the Sun, then gravity wins and the core of that old massive star that has exploded as a supernova becomes a black hole.
So in theory we should have neutron stars and black holes nearby, because 10 million years have passed and those neutron stars and black holes may have dispersed because when a supernova explosion occurs, the resulting object also receives a push that ends up taking it out of the explosion zone, it is not something immediate, but there should still be some black hole from those old supernova explosions
