Summary
Mathematical and physical description of de Sitter space, including its role as the asymptotic geometry of an accelerating universe.
How this source is used on the map
Useful conceptual reference for any claim about long-term cosmology and the cosmological-horizon temperature.

Linked claims
In a long-lived, accelerating universe, random thermal fluctuations could spontaneously assemble a self-aware brain with false memories of a coherent life. Several modern cosmological models appear to predict such observers should statistically dominate — which is widely treated as a reason those models are wrong, not as evidence about you.
If quantum gravity is right, time may be derived rather than fundamental. Active research; nothing settled.
