Quantum effects make distant objects move together: New research finds this may happen with ripples in space

Galaxies, planets, black holes: to most people, everything about our Universe sounds and feels enormous. But while it's true that much of what happens millions of light years away is large, there are also processes happening at the quantum end of the scale. That's the branch of science which explains how nature works at very small scales--smaller than atoms. At this level, things behave in surprising ways.
