The observable universe began in a gigantic explosion about 13 billion years ago.观测宇宙开始于一个巨大的爆炸，大约13亿年前。 This explosion created everything now known, including space which is currently in an accelerating phase of expansion.这一切发生爆炸造成目前已知，包括空间目前正处于加速阶段的扩张。
About the major mass-energy components of the visible universe, the dark energy (approximately 70% of mass-energy) and dark matter (approximately 25% of mass-energy) we have little knowledge but some falsifiable theories.关于质量的主要能源的组成部分可见宇宙的暗能量（约70 ％的大规模能源）和暗物质（约25 ％的大规模能源） ，我们所知甚少，但一些证伪的理论。 It is expected that we will know more about these things soon.预计，我们将更多地了解这些东西很快。
Our sun is about 4.5 billion years old and in 4-5 billion years from now will enter the red giant phase of its evolution.我们的太阳大约45亿年岁，在4-5亿年从现在开始将进入红巨星阶段的演变。 It is not clear at this point whether the earth will at that time become engulfed in the sun’s outer corona, dragged into the sun and subsequently vaporized, or whether the earth will stay outside of the sun and simply be burned to a cinder.目前尚不清楚在这一点上是否地球将在那时成为吞噬在太阳的外层日冕，拖入太阳，随后蒸发，或是否将继续地球以外的太阳，只是被烧毁的煤渣。 Either way, the Earth will be sterilized at this point.无论哪种方式，地球将会消毒在这一点上。
Even though we just arrived at the scene and thus only see a snapshot of the current Universe’s evolution, we now have the minimal confidence levels required to put some numbers on the long term evolution of things, as in the figure below.尽管我们刚刚抵达现场，因此只能看到一个快照，目前宇宙的演变，我们现在有最起码的信任程度要求把一些号码的长期演变的东西，如低于这个数字。
The above picture shows time on a log scale with base 10, and ends at 10 to the power of 1000 years.上述图片显示的时间记录规模基地10个，并结束于10日至权力的1000年。 That is a 10 with 1000 trailing zeros.这是一个10千尾随零。 At the end of the Universe’s evolution is the ‘heat death’, a state of maximum entropy that makes heat engines, such as you and me impossible.在结束宇宙的演变是'热死' ，一个国家的最大熵，使热发动机，如你和我是不可能的。
Assuming the above description of the Universe’s evolution and ultimate death is correct (a big assumption), then what does all this mean for our everyday life?假设上述描述宇宙的演变和最终的死亡是正确的（一个大的假设） ，那么所有这一切意味着我们每天的生活？ What kind of value system or philosophy can one have if everything ‘runs down’?什么样的价值体系或哲学，才能有如果一切'运行了' ？
When you go on a roller-coaster ride you do not expect the ride to last forever.当你来到一个过山车乘坐你不要指望乘车前往万古长青。 You like to have an exiting time and some fun with nobody getting hurt.你想有一个退出的时间和一些有趣的人受到伤害。 That’s the universe, in a nutshell.这就是宇宙，概括。
