Threats within 100 light years

+0
−0

So I'm making this game where the player has to launch probes into interstellar space within a 100 * 100 light years map to detect threats that could wipe out humanity in a few decades. Everything is going well, except that I could not find enough scientific based threats.

I only came up with a few threats:

  • Gamma-ray bursts
  • Rogue Planets/Black holes/Stars (they do not really work because if the rogue object is going to enter the solar system within a few decades, it's probably a waste of making a 100*100 light years map)
  • Alien life

So is there any other scientific based threats that could wipe out humanity within 100 light years range under a few decades? Or any way to make Rogue objects work?
