to look straight ahead without looking at anything specific

He wouldn't even look at me. He just sat there, staring into space.

staring into space 

when you stare into space you are generally looking in the direction furthest away. its when you have been left to your own thoughts, and with no-one to talk to but yourself, and the pointlessness of losing your eyes cause it takes too much effort you just stare at no place in particular. If you're staring in to space, don't stare at any else, especially not your secret crush, it's weird mate and frowned upon.

that kids staring into space, he must have a LOT on his mind.
