What If a Magnetar Collided With a Black Hole?

in the center of our galaxy the Milky Way there is a supermassive black hole feeding on nearby stars it's called Sagittarius a star and if a giant gravitational monster slowly eating the galaxy isn't terrifying enough there's another cosmic monstrosity lurking around it is it possible that one day they would get a little too close and collapse on each other what would be left of the Milky Way if they did would there be even a slight chance that the earth could get out of that safely this is what if and here's what would happen if a magnetar collided with a black hole this monstrosity creeping through the Milky Way is a remnant of a giant exploded star but it's not just any remnant it's an extremely dense and very magnetic collapsed stellar core magnetar let me refresh your knowledge of magnet ARS they're born when a star at least eight times more massive than our Sun reaches its expiration date and explodes in a beautiful supernova much of that star is gone but the dense core of it remains most of these remnants become neutron stars they spin very fast usually a few times per second and they're composed of neutrons some neutron stars have such strong magnetic fields that they emit electromagnetic radiation from their poles that makes them pulsars and you can observe them with a telescope when their poles face the earth only a few pulsars develop such an extremely powerful magnetic field they become the strongest magnets in the universe the magnet ours they spin once every 10 seconds but their magnetic field is a hundred times stronger than that of a neutron star if one of those magnets came halfway between the moon and well it wouldn't be pretty but would it be as bad from a distance of 26 light years away well what I'd like to know is what a magnetar swallow a black hole or what a black hole gobble up a magnetar the collision of these two giants wouldn't end up in an explosion but in a quiet cosmic merger stretched over billions of years although magnate ours are incredibly powerful they would lose the battle with a black hole depending on the trajectory of the magnetar as well as the size and mass of both the magnetar and the black hole the magnetic monster would be eaten up either hole or slowly piece by piece as the magnetar was being torn apart by the black hole it would be sending gravitational waves throughout the universe disturbing the curvature of space-time once the black hole consumed the magnetar its mass would increase and expand its event horizon and thanks to this expansion more and more stars would be flung into its dark density the black hole would be slowly eating our galaxy starved by star eventually after quadrillions of years of star consumption the black hole could gobble up the Milky Way all of it by that time humanity would most likely be long gone anyway that is unless another cosmic event disrupts this feasts some four and a half billion years from now but that's a story for another what if you
