The science of expansion: Andromeda, gravity, and the ‘Big Rip’

If the universe is expanding in all directions, why is Andromeda hurtling toward the Milky Way?

  • The Andromeda Galaxy and our Milky Way are on a collision course that will obliterate life on Earth 4.5 billion years from now.
  • The universe is expanding in all directions, all at once – so why are Andromeda and the Milky Way drawing nearer? The gravity between them is a stronger force than expansion.
  • The rate of expansion is accelerating. If it continues to speed up, its force may become strong enough pull things apart that are currently held together by superior forces: Our galaxy, the solar system, and even the atoms in our bodies. That possible ending to the universe is known as the 'Big Rip'.

  • One obstacle preventing this kind of treatment from becoming accessible is that it requires invasive surgery, though improved technology could someday change that.
