How the Universe ends and what might happen next
In short: This video explores the ultimate fate of our cosmos, from the death of stars to the eventual evaporation of black holes, questioning whether a new universe could emerge from the darkness.
The video outlines the timeline of cosmic decay, beginning with the death of stars in a few trillion years. It explores the long-term dissolution of matter, noting that protons may decay and matter could dissolve after a thousand trillion trillion trillion years. Eventually, even black holes will evaporate after 10^92 years, leaving the universe in darkness. However, the segment also considers the possibility of a cosmic reboot or the existence of multiverses.
