Poincaré recurrence of the universe
The Poincaré recurrence of the universe is a theoretical scientific model in physics where after sufficient time (estimates are around years[1] or years[2]) the universe will create an exact replica of itself through quantum tunneling.[3][4] This would be through a spontaneous entropy decrease[5], this hypothesis explains that the universe would be a system where the Poincaré recurrence theorem applies.[6] An alternate way the universe could recreate itself after the heat death is through thermal fluctuations[7][8] and fluctuation theorem. In this hypothesis, the universe has no origin, and the recurrence will happen an infinite amount of times. This is explained because the entropy of the de Sitter horizon is , meaning that things will start to repeat after it passes the cosmological constant.[9] It is stated that this hypothesis would only apply if these two things are true:[citation needed]
- All the particles in the universe are bound to a finite volume.
- The universe has a finite number of possible states.
However this has been disputed by Lee Smolin.[10]A criticism describes the idea as "highly speculative, probably wrong, [and] completely untestable."[11]
