Science

This still begs the question what the fuck is space if it can expand? If it's not just empty space and the distance between two objects is increasing therefore the space itself is increasing then space itself has a physical property, like water filling a bath, and the water is growing to fill the bath. The gravitational objects are "pinning" the water the same way that putting a ball inside water displaces the water around it or something. But, water is water, space is space but we don't really understand its physical property the same way?

I do not like thinking about this. It hurts my head.
