    As we approach the end of Crash Course Astronomy, it’s time now to acknowledge that our Universe’s days are numbered.

    Stars will die out after a few trillion years, protons will decay and matter will dissolve after a thousand trillion trillion trillion years, black holes will evaporate after 10^92 years, and then all will be dark.

    But there is still hope that a new Universe will be born from it.
