Speaking of a star here or there for a steller close encounter is one thing, but....
What about a trillion star encounter? Such WILL happen, with Andromeda galaxy and the Milky Way making a beeline for each other. One trillion stars will “collide” with the 100 billion Milky Way stars.
Timeframe for any concerned.... About 3 billion years.
Excuse me? But did you say that'll be 3 million or 3 billion years?
:)
After the merger, will the new galaxy lay off a billion stars?
