Who cares about climate change? We're all going to die anyway when our galaxy is eaten by a violent galaxy-eating galaxy.
Andromeda, the galaxy next door, is like a violent criminal on parole. It's killed before and will kill again.
The UK's Independent reports astronomers say Andromeda has eaten several smaller galaxies and will eventually devour our own Milky Way. They say they know this because there are left-overs from previous meals. So, maybe that makes her more like a 14-year-old with a bag of chips stashed in its room?
- Don't cash in your retirement just yet, though. Andromeda is also apparently a couch potato. They say it's going to be four billion years before she gets around to opening the fridge again.
