Scenario 1: The universe would continue a permanent expansion being get rate.
Therefore, the Milky Way of solar system would have led to gravitationally combined galaxies with very near. In order to exhaust material gas, there are no longer new stars in these galaxies. There are only leaving remnants of black holes and neutron stars, white dwarf stars. (If dark energy is constant).・・・10 ^ 18〜10 ^ '25 years after
Scenario 2: Inflation would slow gradually, over time the expansion will stop. Furthermore, from which the universe starts to shrink, becomes very small and collapses. = "Big crunch"(If dark energy is weakened). ・・・10＾27 years after
Scenario 3: The universe would be expanding at an accelerating pace even more. Because of too rapid pace of expansion, the structure of galaxies collapses. ＝Big Rip［2］（If the dark energy becomes stronger）・・・10＾18から10＾25 years after
○ Future of the universe is due to dark energy.
Dark energy is the unknown energy to accelerate the expansion of the universe. It has similar properties as the cosmological term that introduced by Einstein to keep the static state of the universe without collapse by gravity. 
Its identity might be the energy of a mere vacuum as well as the cosmological term, or some potential energy (of the scalar field) that does not substantially change even in 10 billion years of time scale.
Others, it can be considered such scenarios that gravity theory which defines the cosmic expansion deviates from general relativity, or remnants of the high-dimensional cosmological such as membrane models have created an effective dark energy.
○In the case of scenario 1, it is necessary to escape from this universe after a few trillion years. 
[Expansion of the universe] 
○ For expansion of the universe is the expansion of space-time itself, so it is also possible to exceed the speed of light.
○Currently, the observable universe is expanding at 3.5 times of the speed of light. And expansion is accelerating. 
: In the 18 billion light-years distant, the expansion velocity exceeds the speed of light. = We can not observe in the distance from it.
○Outside of the observable universe is not known whether infinite or finite.
⇒ Therefore, in order to escape from our universe, rather than fly, it is necessary to exceed the time and space.
○But above is hypothesis and it is not intended validated. Moreover, the time requires 10 billion years. Don't worry!
○ Hypothesis over the future of the universe is a situation of "anything goes".
【Future of intelligence】
☆ The important thing for the intelligence is communication between the parallel universe rather than escape from the universe.
☆ Communication between the parallel universe would be done by GAI.
