Reason to be alive 5 billion years from now
The Andromeda Galaxy is currently 2 million lightyears away, but is approaching at a speed of over 500,000 km/hr. In about 5 billion years it will either collide with the Milky Way Galaxy, or fly-by so close that it will FILL THE SKY !!!! Imaging looking up at the night sky and seeing the Andromeda Galaxy there, bigger and brighter than the moon, literally filling the sky as it approached !
