Did galaxies evolve much quicker billions of years ago since expansion hadn't yet pulled them as far apart? In other words, the further back in time you go did matter tend to interact much more frequently so in some sense the interaction-time of the universe is much longer than the actual number of years?
Between two charged particles (electric or maybe neutral particles by gravity) is some force. Moving them away will require energy.
So e.g. you put two charged particles in this expanding space, the ongoing expansion will cause some energy which can be harvested? Can we build our "Zero point modul" which generates energy out of "nothing".<p>We dont even need particles for this effect since this is based on virtuell particles which ghostly appear and disappear (the Casimir effect)?
Or maybe a proper medium would suit better (more particles more energy from expansion) e.g. the densest object like a black hole in this expanding space machine?
The simple answer is "No."<p>The more complicated answer is that empty space is expanding, but matter is not. Gravity, and matter subjected to the various forces, holds together even as empty space expands around it.
Yes if we consider the universal as information and our relationships to it as receivers. We've been expanding our time experience for millennia and will continue to so as long we continue to imagine and create.
