Andromeda–Milky Way collision - Wikipedia

The Andromeda - milky way collision is a galactic collision predicted to occur in about 4.5 billion years between two galaxies in the local group - the milky way (which contains the solar system and earth) and the Andromeda galaxy. The stars involed are sufficently far apart that it is improbable that any of them will individually collide. some stars will be ejected from the resulting galaxy, nicknamed Milkomeda or Milkdromeda. The Milky Way and Andromeda galaxies each contain a central supermassive black hole, these being sagittaruis and an object within the P2 consutration of Andromeda's nuclues. These black holes will converge near the centre of the newly formed galaxy over a period that may take millions of years, due to the process known as dynamic friction: As the SMBHs  move relative to the surrounding cloud of much less of massive stars, gravitational interactions lead to a net transfer of orbital energy from the SMBHs to the stars, causing the stars to be "slingshotted" into higher - raduis orbits, and the SMBHs to sink toward the galactic core.
