I have trouble understanding the following.
Lets take 2 galaxies moving away from each other caused by the expanding universe.
A spaceship traveling between these 2 galaxies, more than one time, will experience a greater distance for each travel.
Therefore my conclusion is, that there must have been created more empty space/vacuum between the 2 galaxies each time the spaceship take another trip.
I have read, that when space expands, then the density of the vacuumenergy remains constant.
So i conclude, that there must have been created more energy and information, coming from nowhere.
But that dosen't make sense to me when I consider the rules about energy/information conservation.
Dosen't conservation in these cases mean constant amount of energy/information?
I already know part of the answer you guys/girls will give me, that there for some reason, haven't been any violation of neither energy nor information conservation.
Im no mathguru, so what I hope for, is some kind of abstract that can give me a basic understanding of why not.
