Galaxies aren't moving through space and away from each other but with space. Some galaxies are already so far away from us, and moving away so quickly, that their light will never reach Earth. It's like running a 5K race, but the track expands while you're running. If it expands faster than you can run, you'll never get where you're going.
Welcome to ...
The place where the world comes together in honesty and mirth.
Windmills Tilted, Scared Cows Butchered, Lies Skewered on the Lance of Reality ... or something to that effect.
