As the expansion of space accelerates, space is created and this seems to break the conservation of energy law. I've googled this but have not found a really good explanation of this.
Imagine for a moment we're so far into the future that there are vast vast voids between what remains of galaxies. Some of these voids may be larger than the current known universe. Background radiation from the big bang has red-shifted to the point that it's wavelength is longer than the size of the known universe.
How is the expansion of space at some mind-boggling rate with nothing in it and no background radiation not breaking the law of conservation of energy?
Second question: Can light actually stretch that far or will it eventually be absorbed into the background quantum fluctuations and "die" so to speak?
Thanks for helping me with my curiosity!
