Billions and billions of galaxies, the universe is so vast, we can't even imagine what those numbers mean. But 14 billion years ago, none of it existed, until the Big Bang. The Big Bang is the origin of space and the origin of time itself. We take a journey through space and time, from the beginning to the end of the universe itself.

浩瀚的宇宙中漂浮着数千亿个星系，我们甚至无法想象这些数字的含义。但在140亿年前，宇宙间还是一片混沌，大爆炸改变了一切。大爆炸是宇宙的起源也是时间的起点。我们将开始一段穿越时空的旅行，从宇宙的诞生直至宇宙生命的终点。
