Conservation of space
OK, I again will try to consolidate a few questions that I have.
1) I was thinking about space and what is space. People here say that space is nothing. They give examples of expanding balloons and the like and say that space is just the distance between particles. I disagree with this. Space is the canvas that matter is painted on. ( heh ... well more complicated than that) Space is not nothing. When space expands it has a specific meaning. Space has properties. The space right outside a black hole differs from the space in the deepest void of the universe. Rates of expansion, curvature, temperature?? Space can have state. Space is not nothing.
2) Space is gravity. Without gravity there is no such thing as space. A true vacuum can not exist. Our universe or at least our visible universe is all connected because at every point in space there is some energy and some gravity. Space does not exist outside of this definition. Gravity not only curves space by it is space. Space and gravity and energy go hand in hand, one can not exist without the other.
3) Because matter and energy are conserved based on the first law of thermodynamics, space is also conserved. What does that even mean? That means that the total amount of space in the universe remains constant. Space can curve, but when space is curved other space needs to be curved to compensate for this curvature.
4) the perceived expansion of the universe is the compensation for the curvature from all the gravity in the universe.
