Sagittarius Emergency

The Sagittarius Emergency (or Sagittarius A* Incident) was the unfortunately successful attempt to decompress a black hole using Mirror technology. The target black hole was Sagittarius A*, the supermassive black hole at the Milky Way galactic centre.

The incident began with Hegemony science vessels firing a Mirror targetting missile into Sagittarius A*, calculating for estimated diameter of object at black hole centre and Mirror radius so as to chop black hole in half. The Mirror destination was simultaneous with set up of a Mirror so that the mass of Sagittarius A* was teleported as close as possible to but only on one side of Mirror. The mass' gravitons were reflected back at itself such that each half of Sagittarius A* sandwiched itself against the mirror. Immediately thereafter, The Mirror was popped and the black hole's mass mass was flipped to the other side.

The result of this was an effect like a shaped-charge explosive where the most dense part of the mass was compressed in all but one direction, where there is nothing but empty space. Immediately thereafter, the mass exploded in that direction, ejecting a lot of heavy element mass at very high speed. An enormous Herbig Haro plume was formed from the high speed matter ploughing through the orbiting stellar system and surrounding dust, which became known as the Sagittarius Emergency Object. Although the process is on a timescale of millions of years, simulations predict the Sagittarius Emergency Object will eventually collapse back in on itself and re-form a supermassive black hole.
