Since the universe is accelerating at an increasing rate, will we eventually have our own isolated/closed systems when the distance between galactic masses (bound by gravity) grows to an accelerated rate beyond the speed of light?
If yes, will our new system collapse into a singularity due to...
Since this universe is a closed system of energy, is the universe expanding?
If yes, is the expansion rate increasing?
If no, does the universe have a finite mass/energy?
Does the law of the conservation of energy apply to the light in our universe?
If yes, is our universe a closed system?
If no, is our universe losing energy?
