   The life of such a system is limited, as the entropy of a closed system can only increase with time.

   It took 4.5 billion years before humanity appeared on Earth, and life as we know it will see suitable conditions for 1 [95] to 2.3 [96] billion years more. Red dwarfs, by contrast, could live for trillions of years because their nuclear reactions are far slower than those of larger stars, meaning that life would have longer to evolve and survive.
