"Dyson's eternal intelligence concept (the Dyson Scenario) states that intelligent beings would be able to think an infinite number of thoughts in an open universe.The intelligent beings would begin by storing a finite amount of energy. They then use half (or any fraction) of this energy to power their thought. When the energy gradient created by unleashing this fraction of the stored fuel was exhausted, the beings would enter a state of zero-energy-consumption until the universe cooled."@en .
