The Big Bang Theory theme

our whole universe was in a hot dense state,宇宙一度又烫又稠密
then nearly fourteen billion years ago expansion started. wait...140亿年前终于爆了炸等着瞧...
the earth began to cool,地球开始降温
the autotrophs began to drool,自养生物来起哄
neanderthals developed tools,穴居人发明工具
we built a wall (we built the pyramids),我们建长城(我们建金字塔)
math, science, history, unraveling the mysteries,数学自然科学历史揭开神秘
that all started with the big bang!一切由大爆炸开始
