True fact: once in a very long while, when you see a meteor shower it's not actually rocks hitting the atmosphere, it's space-mouse mating season. They dance along the edge of the gas envelope and fall to earth to nest.
Space mice pair for life, and they live about six years. They lay their eggs in volcano craters. The eruptions blast them back out into micro g, where they hatch. Their fan-tails function as solar sails.
Encysted and dormant, they float out into the dark, oriented towards a bright star. Sometimes that's a nearby one, sometimes it's a galaxy.
Some of the very first space mice, in their encysted stage, are probably still on their way to the stars they chose, while their clutch mates are billions of years gone.
Space mice live generational atemporality.
Space mouse genes are present in ordinary terrestrial mouse but rarely express. They're super-recessive.
But very occasionally, you get spontaneous appearances of an almost classical space mouse from ordinary mice, and they head for the mountains without really knowing why.
Quite often they will join established space mouse pairs and their DNA will be added to the egg clutch.
When all of Earth is boiled away into the night, there will still be space mice from here drifting in the endless gap between stars and galaxies.

It has even been suggested that space mice might survive the re-bang, the contraction and re-expansion of the universe.
That is highly speculative, of course.
So when you look up at the sky tonight, take a moment and feel comforted by the knowledge that the field of dark is full of space mice, heading out and away along their endless road to the future.
