Two-part documentary which deals with two of the deepest questions there are - what is everything, and what is nothing?
In two epic, surreal and mind-expanding films, Professor Jim Al-Khalili searches for an answer to these questions as he explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness.
The first part, Everything, sees Professor Al-Khalili set out to discover what the universe might actually look like. The journey takes him from the distant past to the boundaries of the known universe. Along the way he charts the remarkable stories of the men and women who discovered the truth about the cosmos and investigates how our understanding of space has been shaped by both mathematics and astronomy.
The second part, Nothing, explores science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. Jim sets out to answer one very simple question - what is nothing? His journey ends with perhaps the most profound insight about reality that humanity has ever made. Everything came from nothing. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim can prove it.

人类到底是如何获得改变行星地球的巨大力量的？在外太空遥望地球的夜景，就能见证到人类对能量的掌控和利用，以及它对人类存在的重要性。谁都离不开能量。我们用能量修建容身庇护之所，为房屋照明，更重要的是，对与生命本身而言，能量亦是不可或缺的。如无法从食物中获得生存的能量，迎接人类的只有死亡。可是，能量到底是什么？又是什么让人类离不开它？为了揭开谜底，科学家们发现并归纳总结了一系列的法则，这些法则将下至引擎、人类上至恒星的世间万物都囊括其中，原来，至关重要的能量也在帮助人类了解着整个宇宙。
这两集纪录片便是要来讲述人类对宇宙法则的发现之旅。一路上，人类终于认识到，不论哪种形式的能量最终都逃脱不了分解、耗散的命运，随之，宇宙也从井然有序的一点走向混沌的另一点。宇宙更是通过在此两点间的不断转换，创造了人类周遭的万物。
