Space explained - look in a "empty" cardboard box - what do you see - space, or area. That space is no different than the space that is light years away. now put 2 tennis balls in the box, push them in opposite directions - what do you have? you have 2 objects moving apart - this doesnt mean that space is expanding - its just 2 objects moving through space. but some scientist make the claim that this is proof that space expands. it is important to analyze data correctly if you are to understand the truth about anything.
