>The Universe's expansion causes all galaxies beyond the former Milky Way's Local Group to disappear beyond the cosmic light horizon, removing them from the observable universe.[89]

>High estimate for the time until normal star formation ends in galaxies.[4] This marks the transition from the Stelliferous Era to the Degenerate Era; with no free hydrogen to form new stars, all remaining stars slowly exhaust their fuel and die.[3]

>By this time, if protons do decay, the Black Hole Era, in which black holes are the only remaining celestial objects, begins.[3][4]

>On this timescale, any discrete body of matter "behaves like a liquid" and becomes a smooth sphere due to diffusion and gravity.[99]

>Estimated time for a Boltzmann brain to appear in the vacuum via a spontaneous entropy decrease.[6]

>Around this vast timeframe, quantum tunnelling in any isolated patch of the vacuum could generate, via inflation, new Big Bangs giving birth to new universes.[103]
