I hope a galaxy hits my house, so I can get out of work.

When we collide the chances of anything hitting anything else is quite small.

If we scaled down the universe so that our sun was 1mm in diameter then our next closest star would be about 17km 18 mi away (earth would be about 4.25 inches away) . Galaxies are so empty they would just sling stars around when they merge/collide.

Mooomm! He’s touching me!
