Organization: Travelers in The Night
Link : Travelers in the Night ; @Nmcanopus
Description: Today’s two stroy:
- A rock from another solar system is likely to have streaked by Earth before heading back into interstellar space.
- Perhaps the reason that we have not detected alien civilizations on distant worlds is because they exist in oceans covered by miles of radiation absorbing ice and rocks.
