Go outside at night and look at the stars. The beautiful sea of stars that surrounds us is billions of years old, and all formed together after The Big Bang. However, the apparent tranquillity of the night sky does not reflect the dastardly effects the Milky Way is having on poor smaller dwarf galaxies that happen to be passing by.

It's a galaxy eat galaxy universe out there, and I'll try to shed light as to how exactly the Milky Way's galactic appetite is an important part of galaxy formation.
