The strange behavior of hypervelocity stars suggests a nearby dwarf galaxy must contain a supermassive black hole. If so, a collision with the Milky Way is inevitable.

A Milky Way collision with a supermassive black hole might be closer than we thought. Hidden deep in the Large Magellanic Cloud dwarf galaxy that orbits the Milky Way on an ever-closing loop, signs of a massive invisible object clocking in at around 600,

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed. HVSs travel much faster than normal stars, and sometimes, they can exceed the galactic escape velocity.

Fast-moving stars zooming through our galaxy might have been slingshotted from a black hole inside the neighbouring Large Magellanic Cloud

The Largest 'Black Hole Jet' Discovered Is Estimated to Be Twice the Size of Our Milky Way We know black holes to be mysterious regions in space where the gravitational pull is so strong that even light can't escape.
