Assuming the cosmic acceleration continues as it will according to most theories of Dark Energy, our observable portion of the Universe (within our horizon) will eventually encompass fewer and fewer galaxies. At some point in the very distant future (hundreds of billions of years from now), there may be no visible galaxies beyond our local group. Any newly born civilization in that era would face a far harder challenge than we do in figuring out the cosmology explained in this chapter. We may therefore be fortunate to live in an earlier part of the Universe’s history when there is still ample observable evidence to show us how we got here.
