The creepiest part of the Universe is that it's mostly patch black empty space.
If the milky way and andromeda galaxies merge it's unlikely any stars will collide because of staggeringly empty space.
If you still can't comprehend how empty space is, here is an example.
Imagine you are traveling in space and a huge cloud of sand is approaching at high speed. Even if your ship gets hit by one grain of sand, it can severely damage your spaceship.
Except that wouldn't happen because each grain of sand on average is TEN KILOMETERS apart from every other grain of sand.
That much empty the space.
